Many agroforestry species have hard seed coats which are impermeable to water and

air or which prevent the emergence of seed parts. Hardseededness tends to be

promoted with delayed harvesting and prolonged drying. Hastened seed germination

is essential for rapid and uniform seedling establishment and to shorten the time of

exposure of seedlings to pests and other stresses. The following procedures are

some pre-germination treatments which may be carried out singly or in combination

to enhance germination of hardseeds.

TAP WATER TREATMENT

Soak seeds in tap water for 1248 hours (depending on species) before planting. Sow

only seeds that absorb water. If a large portion does not absorb water, other

treatments should be used.

BOILING WATER TREATMENT

1. Place seeds (and a stick to stir them with) in cloth bags or used socks.

2. Dip and stir seeds in boiling water (5-10 parts water to 1 part seed) for 3-15

seconds. Longer time is needed for seedlots with thicker coats or with more

hardseeds. Boiling water may also be poured into a container with seeds.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 5/155

Picture 12

HOT WATER TREATMENT

1. Pour hot water (boiling water allowed to cool for about 10-15 minutes) into a

container with seed (10 parts water to 1 part seed).

2. Let stand for 3-10 minutes or until water cools off. Seeds may be left soaked

overnight in cold or tap water.

MECHANICAL SCARIFICATION

Nick-off seedcoat with a knife or nailclipper, or rub with sandpaper, file, or any

rough material, taking care not to injure the internal portion especially the radicle

(rootend). This technique is practical only for small seedlots.

Seed storage and longevity

Seeds, even if adequately protected during storage, still undergo deterioration with

time. Major factors affecting longevity (Iife-span) of mature, viable and healthy

seeds are moisture, storage temperature and pests.

Most seeds are drying-tolerant (orthodox). Under ordinary room conditions (open

storage), viability of these seeds is generally reduced by half within six months.

Seeds with harder seed coats tend to live longer than those with thin coats. For

improved storability, seed moisture and storage temperature must be kept low and

controlled.

1. Store only new, mature, healthy and well-dried seeds, except for a few species

which do not favor drying. Keep these in dry and cool environments for longer

viability.

2. Seeds easily reabsorb moisture. To maintain dryness, place dried seeds in air-tight

containers like tin cans or glass jars with tight-fitting lids and use some water-

absorbing materials like sifted dry wood ash (white), dry charcoal, toasted rice

(cooled), silica gel or pieces of newspaper (to occupy about a fourth of the

container). Place a sheet of paper on top of these water absorbing materials if seeds

are to be put directly into the container. Replace or redry these materials if

containers are frequently opened. Fill the rest of the container with seeds. Plastic

bags may be used to keep seeds dry if sealed by heat.

3. Label containers with the harvest and storage dates and place of harvest (or

acquisition). If possible, also indicate the initial percentage viability or germination

of seeds.

Picture 13

4. Dry seeds may be protected from insects by using naphthalene bails (1 or 2 pieces

per kg seed) or by mixing seeds in the containers with some materials like fine sand,

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 31/155

dry wood ash, powdered seeds of black pepper or neem, plant oils from coconut,

neem, peanut, castor, cotton, etc., (one teaspoon of oil per kg seed).

A few species have seeds which are sensitive to drying and, often, also to cold

temperature (recalcitrant). They have storabilities of only several days to a few

months under ordinary room conditions in contrast to the drying tolerant or

orthodox species. Recalcitrant characteristics are commonly found in many fruit,

plantation and forest species (such as lanzones, rambutan, durian, mangosteen,

mango, jackfruit, avocado, rubber, cacao and Dipterocarpus spp.)

Picture 14

For slightly longer storabilities, keep these seeds wellcleaned and moist (1 to 2 days

of air-drying is generally sufficient to keep the seed coat slightly dry but still moist

inside). Store them in small batches in a cool room in inflated plastic bags (half-filled

with seeds and opened once a day to prevent fermentation) or in perforated plastic

bags. Moist charcoal, peat moss, sawdust, sand or coirdust may also be placed inside

the bags. Moist storage for more than a week requires that seeds be protected from

molds and bacteria. This may mean soaking seeds in a sterilant like the commercial

bleach, chlorox (1 part chemical to 5 parts water) or applying anti-mold substances

like fungicides or some plant extracts (try extracts of garlic cloves, acapulco leaves,

malunggay leaves or achuete seeds). A temperature of 15 C is often used to further

prolong storabilities and, to some extent, reduce infection. Recalcitrant seeds also

need special attention during transport. The life time of seeds can be extended if

extraction is deferred until seeds arrive at the collection site at which time care must

be taken to avoid heating and/or fermentation of fruits by aeration or cooling.

Tree nursery: Establishment and management

The difficulty of procuring tree seeds and their rising cost makes it necessary to find

means to increase seedling survival and growth. Nurseries provide the necessary

control of moisture, light, soil and predators and allow production of healthy and

hardy seedlings. Here are some steps to make construction of a nursery and seedling

culture more successful.

1. Select a good site.

An ideal location would be a place near the house (so that the nursery is often and

well taken cared of), with good soil, near a reliable source of water and where water

does not stagnate. Avoid placing the nursery or raising species in an area where

existing species of the same family have pest and disease problems.

Picture 15

2. Clear the site.

Remove stumps, roots, rhizomes and stones in the area. Leaves and other non-wood

debris can be separated and made into compost.

3. Layout the beds

Picture 16

4. Bulid the nursery structure.

D:/cd3wddvd/NoExe/…/meister10.htm 51/155

Some vegetation surrounding the nursery can provide shade but the following shade

structures can also be constructed:

•

D:/cd3wddvd/NoExe/…/meister10.htm 53/155

Picture 19

Construct a shade roof to provide partial shade. It should be loosely woven and

easily removed when the seedlings need to be hardened off.

Examples:

Picture 20

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 54/155

Banana leaves or cogon grass can be added to any of these to provide more shade if

needed.

5. Prepare the germination beds.

If many seedlings are to be raised as in for fuelwood or timber plantation, it is

generally easier and cheaper to raise them in a seedbed and transplant the bare-root

seedlings (uprooted seedlings without soil). This technique works best for hardy

species with a strong taproot, such as mahogany or yemane. Bare-root seedlings are

easier to transport and plant than potted seedlings. However, survival is lower.

Small or delicate seeds are those with low or unknown

germination percentage, are best sown in a seedbed or seedbox and then

transplanted to pots, if desired.

Seedbed

Dig the soil, break lumps of earth and remove remaining roots and rhizomes.

Loosen the soil and make a raised bed, narrow enough to allow for weeding without

stepping on it.

Add compost and river sand. Mix well. Sand loosens the soil for better drainage and

easy uprooting of the seedlings.

Level the bed. Using a bolo or a stick, make shallow furrows.

D:/cd3wddvd/NoExe/…/meister10.htm 55/155

Picture 21

Sow the seeds (treated with protectants necessary) in the furrows. Allow sufficient

room for the seedlings to grow if they are to be directly outplanted. If the seedlings

will be transplanted to pots when they are still small, the seed may be sown more

densely.

Cover the furrows thinly with soil no more than 2-3 times the thickness of the seeds.

Picture 22

Scatter wood ash all over the seedbed if ants and snails are a problem.

Water the seedbed carefully.

Use mulch (or plastic) like rice straw, grass, compost and partly decomposed forest

litter to protect the seed and soil from heavy rains and weeds and to keep the soil

constantly moist.

Make sure to allow enough time for the seeds to germinate. Some tree seeds, such as

mahogany, may take a full month to germinate.

Seedbox

Use a seedbox for very small seeds like eucalyptus and agoho, Benguet and Mindoro

pine and Kaatoan bangkal.

Build a wooden seedbox with 10 cm deep sidings and with holes in the bottom for

drainage. An old washbasin can also be used if holes are punched in the bottom.

Elevate the seedbox to allow drainage.

D:/cd3wddvd/NoExe/…/meister10.htm 57/155

Picture 23

Place the seedbox in a shelter or under a protective roof. Also, set the legs of the

seedbox in cans with water to prevent the seeds or seedlings from being attacked by

ants.

Prepare the medium of equal parts soil, sand and compost. If possible, screen the

soil through fine wire mesh to break up any clods or lumps.

Cover the bottom with 3 cm layer of pebbles or gravel, then fill the seedbox with the

medium.

Picture 24

Pour boiling water over the seedbox to sterilize it and to prevent damping off.

Broadcast the seeds, then cover them with fine sand or soil. Another method is by

mixing the seeds with the medium before broadcasting.

Watering should be done in the morning and in the afternoon with the use of a

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 58/155

sprinkler with a fine mist.

6. Transplant seedlings into individual pots.

If only a few large seedlings are to be raised, it is better to pot them. Fruit tree

seedlings are almost always potted, as rootstocks for budding and grafting.

Picture 25

Large seeds of good viability may be sown directly into pots. The point on the seed

where it is attached to the fruit is called the hilum. This is where the root will

emerge, so plant the seed with this point downwards.

Prepare the seedling pots as the seeds start to germinate.

Mix equal parts of sand, soil and compost. Pulverize soil to break up clods and lumps

If seedling bags are to be used, perforate the bags and fill them with the medium up

to the brim, firm enough to stand. Push inwards the two pointed ends of the bags to

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 59/155

flatten the bottoms. Arrange neatly in the nursery

Picture 26

Use small (4"x6") plastic bags for forest and fuelwood trees and others which will

be outplanted in 4 to 6 months. Use large (6"x8" or larger), sturdy bags for large

seeds, for rootstocks and other trees kept in the nursery more than 6 months.

Bamboo pots can be made by sawing sections to length and cutting a hole in the

node for drainage. These should be presplit and tied back together again to make

removal easier at planting time. Tamp soil in the base to form a bottom. Tin cans can

likewise be used by removing both ends and filling with soil. Folded banana leaf

sheaths may also be filled with soil and used to pot seedlings, but these must be

replaced while the seedling is in the nursery as they quickly rot.

Seedlings are ready to be transferred to individual pots when they have developed at

least two true leaves and when the stem is already sturdy.

Water the seedlings and the seedling pots. After about two hours, start transferring

the seedlings.

Thrust a pointed stick in a seedling pot to make a hole. Plant one seedling per pot

taking extra care not to break the roots or bend the tap root. Press the seedling base

firmly but gently with the fingers to make sure seedling is stable.

Picture 29

Water the seedlings daily. Weed as needed.

7. Prune tap root to develop a stronger and more compact root system.

If the tap roots have penetrated the bottoms the plastic bags or other pots, lift the

seedlings off the ground or slide a bolo under the pots to prune the tap roots.

8. Harden off the seedlings a month before field planting.

Gradually remove the roof over the seedlings until they grow in full sun.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 63/155

Reduce frequency of watering to every other day.

If seedlings are overgrown, the shoots and leaves need to be trimmed back.

9. Sort or grade the seedlings according to quality.

Separate vigorous, healthy seedlings and utilize them for field planting.

Remove or cull out sickly or very poor seedlings.

Rooting of cuttings in homemade mist chambers

Propagating trees by using cuttings will reproduce the desired exact characteristics

(like size of fruits, sweetness) of the trees you want, shorten their maturity period,

dwarf their size, multiply them fast over a short period.

Common perennial trees you can propagate by cuttings are citrus (lemonsito,

oranges, lime, etc.), guava, rambutan, barbados cherry (aserola), coffee, cacao and

black pepper.

A simple way of propagating cuttings is done thru the use of a homemade

propagation chamber described in tines sheets. The process detailed here has been

tried at the Mindanao Baptist Rural Life Center and is found practical for a small farm

and community nursery project.

PROCEDURE

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 87/155

Make a propagation chamber.

Picture 57

1. Use a wooden or concrete box with the size indicated in the illustration or

according to the number of seedling to be propagated.

2. Line the inside wall with plastic sheet to ensure that moisture is retained for a

longer period. Cover the lid with transparent plastic sheet to let in some light.

Fill with river sand.

1. Secure well-washed river sand and stones.

2. Line the bottom of the box with stones to prevent the sand from being washed

out.

3. Sterilize the sand either by sun-drying or pouring boiling water over it.

4. Place under shade facing east.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 88/155

Picture 58

Prepare and plant the cuttings.

General rule. Choose the young stem. Cut at the node and cut half of the leaves off

for slower transpiration. Cut root end may be dipped in rooting hormones to

facilitate root development.

Citrus and cherries. Cut 10-12 cm from the tip. Choose the green stem, not the

yellowish or brown ones. Cut about two cm from the terminal bud. Cut leaf blades in

half. Barely touch the node with full strength growth hormones for one second. Plant

in the sand inside the chamber.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 89/155

Picture 59

Coffee. Choose green, young watersprouts. Cut 4-6 cm below the node. Remove

lateral branch, cut leaf blades in half, cut stem vertically to produce two planting

materials. Dip in rooting hormone as in citrus. Plant

Picture 60

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 90/155

Blackpepper. Choose the runners or the vertical, climbing branches for propagation.

Lateral branches do not climb. Cut four to six cm from the node, leave two to three

nodes for every cutting. Rooting hormone is not needed. Plant into chamber.

Picture 61

Make the chamber air-tight.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 91/155

1. Conserve moisture to prevent dehydration or wilting of the cuttings.

2. Open the chamber (about three times a day) to avoid the incidence of fungus

attack.

3 Frequency of watering depends on the rate of drying of your chamber. But as a

general procedure, water once in the morning and again in the afternoon.

4. Water carefully to avoid toppling the cuttings.

Transfer rooted cuttings.

1. It will take 1.5-2 months before cuttings develop enough roots.

2. Uproot carefully and transfer cuttings into polyethylene bags (6" x 7") with soil

mixture of equal parts of sand, compost of manure and soil.

3. Let the potted cuttings remain under shade and wellwatered until they develop

new shoots.

4. Harden seedlings for about a week under the sun or partially shaded area before

transferring to the field. Place in moist bag when transporting.

Agroforestry, the land management system of incorporating crop production with

tree and/or production, evolved to become one of the most widely promoted tools

for sustaining development in the uplands. To supplement the materials used by

upland development extension workers in promoting agroforestry, a group of

specialists, technicians and farmers from 11 government and nongovernment

organizations met at the invitation of the international Institute of Rural

Reconstruction in Silang, Cavite in November 1989 to develop the Agroforestry

Technology Information Kit (ATIK). In November 1992, some of the specialists,

together with some farmers and an additional number of specialists and technicians,

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 94/155

met again at IIRR to revise the ATIK.

The updated kit is handy, easy-to-understand and full of illustrations. It widely uses

indigenous technologies. With this kit, it is hoped that extension workers and upland

dwellers develop a better understanding and appreciation of agroforestry. The

success of agroforestry as a tool for sustaining upland development$ however, will

depend on how this tool is introduced and implemented. Sustainable agroforestry

systems can only be attained if upland dwellers are involved in the planning and

establishment of such systems.

I commend all those involved in the production of this useful kit.

Workshop to revise the agroforestry technology information kit (ATIK)

The first workshop to develop the Agroforestry Technology Information Kit - now

more popularly known as ATIK - was conducted by the International Institute of

Rural Reconstruction (IIRR) in its Silang Campus, Cavite, Philippines, on November

4-13, 1989. There were 39 participants to this workshop who came from 11

government and nongovernment organizations (GOs and NGOs).

ATIK was produced primarily for use by DENR technicians who have been

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 96/155

implementing the Social Forestry Program nationwide. DENR conducted a

nationwide survey among its staff who were involved in the implementation of its

Integrated Social Forestry Program and also primary users of ATIK. A questionnaire

was formulated, focused on the actual experiences of these technicians in using the

ATIK and on specific revisions they proposed to make on the kit. A Planning

Committee was created to study the technicians' proposed modifications to the

ATIK, as well as to plan for the workshop to revise it. The committee was composed

of For. Domingo Bacalla of DENR, For. Moises Butic of DENR, Ms. Rowena Cabahug of

UPLB College of Forestry, Dr. Romulo del Castillo of UPLB College of Forestry, Ms.

Remedios Evangelista of DENR, Dr. Julian Gonsalves of IIRR, Mr. Scott Killough of

IIRR and Mr. Jaime Ronquillo of IIRR.

The workshop to revise the ATIK took place also in IlRR's Campus in Silang, Cavite,

on November 16-21, 1992, with 45 participants representing 13 agencies. These

agencies included: the Department of Environment and Natural Resources; Farm and

Resource Management Institute; Southern Mindanao Agricultural Programmer Mag-

uugmad Foundation, inc.; University of the Philippines at Los Baos; Development

Program/Sungay Upland Farmers' Golden Harvest Association; Soil and Water

Conservation Foundation; Quirino Livelihood Concept and Development Resource

Center, Inc.; Winrock International: Mindanao Baptist Rural Life Center; Visayas

State College of Agriculture; International Rice Research Institute; and, IIRR.

In the workshop, the same process for materials production was followed. Old

sheets and first drafts of new topics were presented by the au hors in plenary

sessions. These materials then underwent continuous improvements through the

critiquing of the other workshop participants. Communication experts (writers,

editors, layout and design artists) were on hand to assist the authors in

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 97/155

revising/preparing the texts, illustrations and designs of their papers. Before the

materials were prepared in a camera-ready format, they were submitted to their

authors for final review and revision to ensure that the additional corrections were

incorporated.

The major revisions of ATIK are the following:

A. Format

1. From a set of loose-leaf single sheets in folder/binder to six,

pocket-size (4" x 7") booklets, individually classified and bound

according to major topics

2. Using simple, white, ordinary bookpaper, rather than the thicker,

colored and more expensive bristol board

3. Using a thick binder to hold the six booklets, instead of an individual

folder for each kit.

B. Content

1. Some old topics which were found not relevant/useful from the

survey were dropped from the kit.

2. Other topics were revised, focusing on the specific needs of the

DENR technicians.

3. Additional, new topics were included, again to respond to the

expressed needs of the technicians.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 98/155

4. Many old topics - which were adapted by farmers - remained as they

were.

The revised ATIK - with its new format and content - is expected to further facilitate

the work of DENR's 1,200 technicians in its Integrated Social Forestry (ISF) Program

nationwide. Ultimately, the kit will help enable DENR's ISF's program to give the

Filipino uplanders access to forest lands for a tenure of 25 years or more.

Current program thrusts in upland development

Human greed, abuse and misuse of the country's forest resources have resulted in

the sad state of our uplands today. Resource depletion, degradation, inequitable

access to resources, tenurial issues, upland poverty and the continuous influx of

lowland migrants into the uplands are among the current issues in natural resources

management.

In recent decades, the Philippines witnessed an unprecedented commercial

exploitation of the timber resources leading to an annual rate of deforestation

reported to have reached an average of 119,000 hectares during the declining years

of the timber boom between 1969 to 1987. From a leading exporter of precious

"Philippine Mahogany", the Philippines has become a timber deficit country where

the cost of a board foot of lumber is beyond the means of an average wage eamer.

The disappearance of forests has resulted in the loss of jobs and livelihood in

neighboring communities; destructive floods and drought during wet and dry

seasons, respectively; and, landslide and siltation of rivers and dams. Other

consequences of deforestation have become common occurrences in many parts of

the country.

Through the years, landlessness and unemployment have driven hundreds of

thousands of poor families in the lowlands to migrate and eke out a living in upland

areas where they have become "squatters" by operation of law. In many cases,

these have resulted in the total destruction of remaining forest vegetation in the

area. The land has become marginally productive as the top soil continues to be lost

through erosion brought about by improper agricultural practices. The result is

poverty and a degraded upland environment affecting not only the people who

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 112/155

subsist in these areas, but even the poor farmers lowlands who likewise suffer from

the inevitable consequences of forest destruction. Latest estimates show that as

much as 8.25 million hectares are now severely eroded.

In view of these problems, the government has in recent years formulated programs

directed at arresting resource depletion and environmental degradation while

searching for solutions to the issues of secured access to land, poverty alleviation

and increased sustainable productivity. Among the major programs being

implemented by the Department of Environment and Natural Resources are the

Integrated Social Forestry Program (ISFP) in noncritical areas of the public domain

that are under various forms of cultivation; the National Forestation Program (NFP)

in degraded areas and in residual stands that are inadequately stocked; the Forest

Land Management Agreement (FLMA) in newly reforested areas under the NFP that

need to be maintained and cared for; and, the Community Forestry Program (CFP) in

residual forest lands occupied by farming families.

1. INTEGRATED SOCIAL FORESTRY PROGRAM (ISFP)

Initiated about a decade ago, the ISFP draws strength from the DENR Upland

Development Program (UDP) started by the Bureau of Forest Development in 1980

which was aimed at distilling lessons and developing methodologies for

participatory management of the uplands. The ISFP incorporates the best features of

three people-oriented forestry programs implemented in the 1970's, i.e., Forest

Occupancy Management, Communal Tree Farming and Family Approach to

Reforestation. The major features include granting longterm tenurial arrangements

to qualified applicants, technical and modest material assistance and institution

building aimed at developing capability for community-based resource management.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 113/155

ISFP addresses the twin problems of rural and ecological stability in occupied forest

lands. Through ISFP, forest land occupants are provided secure access to land as

well as technical and material aid to make the land productive without depleting it.

Secure land tenure comes through either the Certificate of Stewardship Contracts

(CSCs) for individuals, or the Community Forest Stewardship Agreements (CFSAs)

for community organizations. In both cases, farm families are granted renewable 25-

year leases on the public land which they occupy and cultivate. In the first years of

the lease, the farmer receives technical assistance for developing self sufficiency and

sustainable farming practices.

The program provides assistance in the areas of agroforestry, land tenure and

community organizing. Community organizing is applied to mobilize groups to obtain

stewardship contracts, promote agroforestry and soil/water conservation and build

local institutions. ISFP emphasizes improvement of existing farmer practices, not

introduction of new ones except in situations where such may be necessary.

Participatory strategies are used to gather data, diagnose field situations and

monitor technical problems. Farm visits and training courses develop farmers' skills

in agroforestry and organization, in the process, community leaders are prepared to

take responsibilities for continued development after the end of the project,

tentatively set at five years.

Recently, the implementation of the Local Government Code obligated the DENR to

devolve to the Local Government Units (LGUs) the management of all ISF project

sites except some of the "model sites" (one model site per province) and the UDP

sites. These projects will remain under the care of the DENR for use as learning sites

where new technologies and approaches are expected to be generated. These sites

will also be used as training areas for LGU and other development workers as part of

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 114/155

the outreach program of the DENR.

2. NATIONAL FORESTATION PROGRAM (NFP)

In 1988, the DENR implemented the NFP which consists of three major components,

namely: reforestation, watershed rehabilitation and timber stand improvement. The

reforestation component is concerned with the replanting of denuded forest lands

with indigenous and exotic forest species, including fruit trees, bamboos and minor

forest species. One of the reforestation strategies used is assisted natural

regeneration (ANR) where augmentation planting of climax species is done to

improve future yield at minimum cost. The timber stand improvement (TSI) involves

the removal of over-mature and inferior trees to improve growth in logged-over

areas. Reforestation, ANR and TSI are approaches used in rehabilitation of identified

critical watersheds and catchment areas.

DENR enters into contract with upland settler families, community and

civic/religious organizations, entrepreneurs, local and other government offices and

other NGOs for any of the above NFP activates in areas identified by DENR. The

contract may be for survey, mapping, planning, community organizing/training,

monitoring and evaluation or actual comprehensive site development of a given area.

3. FOREST LAND MANAGEMENT AGREEMENT (FLMA)

FLMA provides a long-term tenure to the people who plant and care for trees

reforested areas by granting farmers access to these areas for purposes consistent

with sound ecological principles. When the reforestation contract terminates after

three years, the contractor may apply for an FLMA if at best 80 percent of the trees

planted are surviving and properly maintained. Family contractors must organize

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 115/155

into associations or cooperatives covering a total of at least 100 hectares. DENR

employs local NGOs to help organize communities and train them in forest

management.

Like stewardship contracts under ISFP, FLMAs are for 26 years, renewable for

another 25 years. The contractor may use the area to grow and harvest minor forest

products or interplant cash crops, fruit trees and other agricultural crops using

sound agroforestry practices. The contractor may also harvest, process and sell

timber when the trees mature, following the principles of sustained yield forest

management. In return, the contractor provides DENR 30 percent of the total

proceeds until the whole cost of reforesting the area has been recovered. The

proceeds will be deposited into a "trust fund" for expanding reforestation activities.

4. COMMUNITY FORESTRY PROGRAM (CFP)

The need to democratize access in the use of the forests and allow organized upland

communities to benefit from the resource compelled the government to adopt

policies that would enable communities to protect, manage and rehabilitate

fragmented residual and old growth forests. CFP is emerging as a community-based

approach in managing certain portions of abandoned, canceled and expired areas of

Timber License Agreements (TLAs).

CFP makes upland dwellers stewards of residual forest areas. Communities are

awarded 25-year Community Forestry Management Agreement (CFMA). Again, these

agreements are renewable for another 25 years if mutually agreeable to DENR and

the community. The community organization can harvest, process and sell forest

products from the area according to a management plan submitted to DENR

beforehand. The plan must comply with prescribed rules and follow principles of

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 116/155

sustained yield management.

Under the CFP, DENR assists the holder organization to set up and strengthen the

community organization. This includes on-the-job training in resource inventory,

preparation of forest management and conservation plans and developing livelihood

opportunities. For this assistance, DENR employs qualified NGOs.

ROLE OF NGOS

Through the years, the NGOs have been doing a proactive role in upland

development through advocacy, training and technical assistance. However, the

latter part of the 1980s offered greater opportunities for their direct involvement in

the implementation of government programs such as reforestation, social forestry

and community forestry. In addition to their traditional roles, the NGOs are now

involved in technical work such as survey and mapping; resource appraisal and

planning; community organizing; reforestation; resource management; and,

harvesting, processing and sale of forest products.

A TOOL IN UPLAND DEVELOPMENT

Agroforestry is an important tool in the development of the uplands. If practiced

properly, it helps promote soil and water conservation while increasing productivity

and sustainability of upland farms to the benefit of the people.

There are traditional astute agroforestry practices being employed mostly by

indigenous people in the uplands. The great majority of the population, however,

remains in need of improving their system of farming the uplands to increase income

and protect the environment.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 117/155

Meanwhile, the number of people being engaged in promoting appropriate

agroforestry technologies has dramatically increased in recent years. They come

from national government agencies, various nongovernment organizations and, more

recently, technicians of local government units to whom the upland development

functions have been devolved.

This Agroforestry Technology Information Kit (ATIK) has been developed for use by

these types of development workers as a quick reference. It consists of simple,

illustrated technologies being used in various parts of the country. It is a product of

a week-long materials production workshop among agroforestry practitioners in the

government and nongovernment organizations, farmer groups and the academe.

Seeds and plant propagation: An overview

The seed or any form of planting material (generally termed propagule) is a basic

requirement in all development programs, i.e., agricultural crop production,

agroforestry, plantation and reforestation projects. Unfortunately, its supply has

always been a problem. The production, multiplication and handling technologies of

these are also not well-known or established. The desire to meet the pressing need

for propagules has often led to the sacrifice in quality, suitability and overall

sustainability in favor of assured supply. K must be remembered that the form, type

and quality (such as viability, germinability, vigor, health, purity and authenticity,

moisture content and genetic uniformity) of the propagule contribute greatly to the

success of a development undertaking.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 120/155

The form of propagule, i.e., whether they are seed or clone (asexually or vegetatively

propagated materials such as cuttings, marcots, grafts, tubers, corms, suckers, slips,

tissue culture seedlings) could spell the degree of genetic uniformity of the plants or

trees in a population. Clones are genetically uniform having come from the mother

tissue. They did not undergo sexual reproduction or fertilization to produce a true

seed and a different individual. They may be the more feasible form of propagation

for some difficult-to-seed species, where the same characteristics as the mother is

desired and/or when shorter time is desired to bear fruits. However, they have

generally shorter life span than plants from seeds.

Some seeds, referred to as apomicts as opposed to true seeds, are produced without

fertilization (e.g., many forage grasses). Others, such as mango and citrus species,

have polyembryonic seeds producing several embryos one of which is sexual and the

others, clones.

Genetic uniformity of true seeds varies depending on the type, i.e., whether they are

hybrids or open-pollinated. Hybrids are seeds or plants produced through highly

controlled pollination. They are highly uniform and generally expensive. Unlike

clones, they cannot be authentically recycled, although may be asexually propagated.

This is because plants from their seeds or the succeeding generations are highly

variable and different from the original hybrid variety. Open pollinated plants or

seeds, on the other hand, are produced through natural crossing and composed of

more variable plants in a population. In nature, many species, such as cabbage,

carrots, cucurbits, onions, corn and many fruit and forest species, are of this type.

Such plants could be recycled, unlike hybrids.

Naturally self-pollinating species, such as rice, many legumes, tomato, pepper and

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 121/155

lettuce, have varieties with genetically uniform plants (purelines or inbreds). Unlike

hybrids and as in clones and open-pollinated varieties, purelines could be recycled

for several generations. They could be made more genetically diverse in the field by

planting together different varieties or populations of the species.

The way seeds are collected also affects the genetic uniformity of succeeding

generations of plants. Collecting and planting seeds from only one or a few plants,

especially of cross-pollinating species could lead not only to genetic uniformity but

also to loss of the original characteristics of the variety. This is because the genetic

traits of the variety may be carried by different plants in the population. Some genes

may be left out and eventually disappear due to limited sampling. The widespread

use of a single species of variety, especially when they are genetically uniform, has

led to crop failure due to pest epidemics end environmental stresses. It has also led

to the loss of indigenous species and varieties (genetic erosion) and biological

diversity of many ecosystems.

Some known technologies applied to propagules are useful and effective, but only in

meeting short-term needs. In many cases, their appropriateness especially in the

long nun is a question. This is with particular reference to their effect on the farmer's

self-reliance, the environment (as with the use of chemical inputs, non recycling of

nutrients and continuous monocropping) and the economics of the farm or the

project itself. Development and adoption of sound alternative technologies in

propagation and handling, therefore, need to be actively pursued.

Timing of seed collection

The value of a seedlot depends on its authenticity or "trueness-to-type", germination

capacity. general health and ability to withstand stresses in the field and during

storage. To a large extent, selection of mother trees, of fruits in the tree and the

technique and timing of seed collection determines the quality of harvested seeds.

To assure e good quality seedlot, seed collection Ups should be observed.

healthy, with abundant and healthy fruits and of good growth and form representing

the purpose for which it is grown (i.e., for timber, fodder or fruit). Collect only from

mature and healthy trees. Avoid very young trees or plants.

Also, avoid choosing an area where only few trees of the same species grow,

especially if they are naturally cross pollinating. A large population gives a better

chance of selecting good mother trees. Avoid collecting in stands with numerous

poorly-formed, off-colored, abnormal o_r disease-infected trees. Collect fruits/seeds

from trees standing in the center of the field. Make sure that seeds come from many

trees of the same kind and quality to ensure that the seedlot contains all the

representative characteristics of the variety.

METHODS OF FRUIT/SEED COLLECTION

1. From the ground

Collecting fruits/seeds from the ground is common especially for large-fruited

species or species with seeds that are naturally dispersed. Although convenient, this

practice increases the risk of collecting immature, empty, decayed/deteriorated and

sprouted/germinated seeds. Identifying the source of seeds (mother trees) would

also be difficult, especially when crowns of trees are interlocking.

Some points to consider in collecting fruits/seeds from the ground:

· Gather sound fruits and seeds right after they have fallen. Avoid collecting first

fruits that fall during the season as they are often of poor quality.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 125/155

· Shedding of mature fruits/seeds may be induced by shaking the trunks of small

trees. Long poles, aided by hooks and ropes, could be used for taller trees. Lay a mat

on the ground to avoid seeds from touching the ground and to facilitate collection.

Examples of seeds that can be collected from the ground:

•

••

•

heavy, fleshy fruits

kaatoan bangkal (Anthocephalus chinensis), kamagong (Diospyros phi/ippensis),

santol (Sandoricum koetjape), pangi (Pangium edule)

•

••

•

medium-sized fruits with hard kernel

lumbang (Aleurites moluccana), bagilumbang (Aleurites trisperma), yemane

(Gmelina arborea), teak (Tectona grandis), talisay (Terminalia catappa), kalumpit

(Terminalia microcarpa), bitaog (Calophyllum inophyllum), pill (Canarium ovatum)

•

••

•

large pods

fire tree (Delonix regia), rain tree (Albizia saman), antsoan (Cassia javanica),

sampalok (Tamarindus indica), ipil (Intsia bijuga), tindalo (Afzelia rhomboidea),

dapdap (Erythrina spp.)

•

••

•

large capsules

mahogany (Swietenia macrophylla), kalumpang (Sterculia foetida)

•

••

•

large winged fruits

Direct access from the ground. Pick fruits/seeds from the lower branches by hand.

Bend, cut, break or saw branches. Examples are: calliandra (Calliandra calothyrsus),

madre de cacao (Gliricidia septum), rensoni (Desmodium rensonii), sesbania

(Sesbania rostrata) and katurai (Sesbania grandiflora).

Climbing trees. Pick fruits/seeds from higher branches by climbing up the trees. This

technique assures seed collection from well-identified mother trees. It is also

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 128/155

applicable for small-seeded species, winged seeds, fruits/pods that split open when

mature, or fruits/seeds that are prone to insect, rodent and mold attack on the

ground. Examples are: (1) small berries or drupes (e.g., Eucalyptus species,

bottlebrush); (2) leguminous species which open their pods on the tree (e.g., ipilipil

Leucaena spp., Moluccan sau Paraserianthes falcataria, kamachile Pithecellobium

dulce, tanglin Adenanthera intermedia); and, (3) small, winged, wind-disseminated

seeds (e.g., Benguet pine Pinus kesiya, Mindoro pine Pinus merkusii, Japanese alder

Alnus japonica, agoho Casuarina equisetifolia, dita Alstonia scholaris, African tulip

Spathodea campanulata, kalantas Toona calantas, banaba Lagerstroemia speciosa).

Special skills and support equipment (like ladders, climbing iron with spikes, safety

belts) are needed to access fruits from higher parts of the tree.

3. From crowns of felled trees

Collection of seeds from felled trees is easier and usually a lot quicker. However, this

should be avoided as much as possible since this could lead to significant reduction

in tree population and expose the soil to erosion.

TIMING OF SEED COLLECTION

1. Collect fruits/seeds at about mid-moming or midafternoon when it is sunny and

not windy. This avoids pod shattering or obtaining pods or seeds that are moist with

dew.

2. Harvest fruits/seeds only from trees where most of the fruits are mature (i.e.,

avoid overmature and immature ones). Do not collect seeds from fruits that flowered

early or late.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 129/155

3. To know when a fruit or seed is mature requires familiarity with the species. Some

common indices of maturity are changes in size, texture and color (usually from

green to various shades of yellow, red, purple, brown or black). Certain fruits dry up

while others become soft and sometimes aromatic when ripe. Collect seeds from

shattering fruits, cones or pods (e.g., pine, eucalyptus, ipil-ipil Leucaena spp., agoho,

Moluccan sau, banaba, Acacia mangium, akle Serialbizia acle and Sesbania) before

they dry up and shed or when still greenish or yellowish in color. Maturity of those

with closed cones or fruits, e.g., Gmelina, can be assessed better by cutting through

and examining the fruit. Collection of green or yellow fruits would also minimize

fermentation during temporary storage of unextracted seeds.

RECORD-KEEPING

Mark mother trees for future collection. Record the site, location of trees within site

and date of collection. This will serve as reference in evaluating performance of

seedlots in relation to origin and seed source (provenance) as well as predicting

seed longevity.

EXTRACTION

A. For dry fruits (pods and cones)

Sun-dry over concrete, canvas sheets or cloth sacks until pods split open. Placing the

pods on a wire mesh with an accompanying container at the bottom is also a good

technique. The container will catch the seeds when the pods split open.

Trample with feet, toss around or beat pods inside a sack to speed up seed

separation. Open manually or mechanically pods/cones which do not easily split

open.

Picture 5

Clean seeds by blowing or winnowing.

To get cleaner and better quality seeds, immerse seeds in a container of water for

one to several hours. Discard those that float. Drain and redry the remaining seeds

well. Avoid soaking seeds for too long as this may cause fermentation. Soaking

should also be avoided for seeds which rapidly expand to avoid damage. When seeds

are to be planted immediately, redrying may be omitted.

Picture 6

B. For fleshy fruits

If possible, extract seeds only upon arrival at the collection center. Do not delay

extraction for too long and never store fruits piled-up and undisturbed, as heating

and fermentation may kill the seeds or reduce their quality.

Seeds in fleshy fruits may be extracted manually or made to undergo a depulping

process. This process entails the following steps:

1. Immerse fruits in water for 1-2 days until the fleshy tissue becomes soft.

2. Scrape, crush or nub lightly with hands to separate seeds thoroughly from pulpy

flesh, but avoid injuring the seeds.

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 146/155

3. Discard all floating seeds and pulp (most seed species are sinkers.

4. Drain seeds, rewash and air-dry for 1-2 days before sun-drying.

5. Winnow to dean.

Examples of species with fleshy fruits that need depulping: Aleurites spp., Canarium

ovatum, Syzygium cumin), Gmelina arborea, Azadirachta indica, Ocotea

usembarensis and Cinnamomum camphora.

For some species which have seeds covered only by thin layer of flesh (e.g., Vitex

parviflora), the fruit itself may be kept intact, dried and directly sown. However,

germination may be further improved by removal of the pulp.

DRYING OF SEEDS

Sun-dry the extracted, cleaned seeds for 1-3 days (depending on the weather and on

how wet the seeds are) if seeds will be stored for future use. Airdry washed or wet

seeds for 1-2 days before sundrying.

1. Lay a mat, canvas, light-colored plastic sheet, winnowing basket or screen on the

ground where the sun shines all day.

2. Spread the seeds thinly and evenly.

3. Stir and turn the seeds 4-5 times a day for uniform drying. If possible, keep seeds

(especially moist ones) shaded during intense heat (noon to 2:00 p.m.).

4. Before it rains or gets dark, take the seeds indoors.

19/10/2011 Seeds and Plant Propagation. Agrofore…

The same drying procedure may be used for seeds of most fruit trees. Exceptions are

seeds of lanzones (Lansium domesticum), rambutan (Nephelium eappaceum), durian

(Durio zibethinus), mangosteen (Garcinia mangostana), man go (Mangifera indica),

jackfruit (Artocarpus heterophyllus), avocado (Persea americana), rubber (Manihot

glaziovii), cacao (Theobroma cacao) and Dipterocarpus spp. These should not be

sun-dried but may be air-dried for a day or two before storing or they must be

planted immediately after extraction.

Seed quality testing

The quality of a seedlot determines how well seeds store or perform in the field. To

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 149/155

assess the quality of a seedlot, draw a sample from a properly stirred or mixed

seedlot and conduct any of the following tests:

Picture 8

VISUAL INSPECTION

Seed purity is a measure of the cleanness and authenticity ('trueness-to-type") of

the seedlot. It may be known by inspecting the composition of a particular sample.

1. Scoop out a handful of seeds from a well-mixed seedlot.

2. Separate the seeds of interest (pure seed fraction) from other components like

seeds of other varieties and/or species (including weeds), immature, broken,

undersized, shriveled, diseased (with molds/fungus or fungal stains) and infested

seeds (with holes, insects' eggs and larvae, or are partly eaten by insect), chaff,

stone, soil, etc. If a large portion of the sample consists of impurities, clean the

seedlot first before storing, shipping or planting.

FLOTATION

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 150/155

1. Most seed species sink in water and flotation serve to separate seeds of poor

quality. Soak seeds in tap water until all seeds are thoroughly wet. This may take a

few minutes to a day.

2. Take out floating seeds and retain sinkers. Poor quality (low viability) seeds often

float while those of better quality often sink. However, some species are natural

floaters (e.g., coconut, nipa and teak); hence, quality must be assessed through

other means.

GERMINATION TEST

Seed germination is the most reliable method of determining seed viability.

However, this takes some time before results can be obtained. Aside from the

problem of slow germination, some alive seeds are dormant and need special

treatments to promote germination. Germination results of samples without any pre-

germination treatment will serve as guide in determining the amount of seeds to

plant or the need for any pre-germination treatment of the seedlot.

Picture 9

1. Sow 50-200 small seeds in moist, clean and absorbent paper or cloth. Roll the

19/10/2011 Seeds and Plant Propagation. Agrofore…

D:/cd3wddvd/NoExe/…/meister10.htm 151/155

paper or cloth loosely (ragdoll method) or keep the medium flat but covered (usually

with another layer of the same material). Larger seeds like Gmelina are better sown

in a seedbox or seedbed containing soil, sand or sawdust for more even seed

wetting.

2. Keep the media moist by constant watering, but take care not to displace the

seeds or to flood the medium. If wooden soil/sandboxes are used, the media may be

kept moist by letting the container sit in a bigger container with water. Paper or

cloth media may also be maintained moist by keeping in a partially opened plastic

bag. Keep in the shade (no direct sun and away from mice, ants and rain.

3. Count normal seedlings after 1 to 3 weeks depending on species. Normal seedlings

are those with well-formed roots and shoots. Percentage germination (G) is

calculated as:

G = (No. of normal seedlings) / (Total no. of seeds tested) x 100

Seeds with a germination percentage of 50 percent or less should either be planted

immediately or replaced in storage. The lower the germination of seed samples, the

poorer is the storability or field performance of the seedlot.

RAPID VIABILITY TEST

The Tetrazolium Chloride (TTZ) test is a quick method of testing seed viability (1-2

days) This is usually resorted to when seed germination takes more than a month or

when quick assessment about the seedlot needs to be made The TTZ may be

purchased from chemical stores in 5 or 10 9 bottles costing about P1,400/10g

bottle.

1. Preparation of solution

a. Dissolve 5 9 of TTZ in a liter of water (approximately 1 motor oil can). This

volume is enough to use for 15-30 tests.

b. Keep the solution in a clean bottle wrapped in black sheet (use carbon paper or

black plastic) and store in a refrigerator for longer effectivity. If a refrigerator is not

available, prepare only the needed amount, maintaining the same proportions.

2. Sample enough seeds (100-200) from a well-mixed seedlot and soak overnight (8-

12 hours). For species or seedlots with hard seeds, dip seeds in boiling (1-3

seconds) or hot (5-15 minutes) water, or nick off seedcoats (at the tip away from

the radicle/root end or initial) before soaking in water.

3. Remove softened seedcoat. Carefully separate the cotyledons (expanded leaf-like

structure) and retain the part with radicle for testing. For species with one cotyledon

or with difficult to separate cotyledons, cut the seed lengthwise revealing all the

essential parts.

4. Add enough TTZ solution to thoroughly immerse the seeds. Cover the set-up with

a black sheet and let stand for 3-6 hours under ordinary room condition. Other

species may require longer soaking time (820 hours) for a more thorough reaction.

5. Drain the solution, rinse seeds with water and spread in a wide container with

water (enough to cover the seeds) to allow individual seed inspection.

6. Seeds with completely colored bright red tissues are alive. Some seeds with

unstained parts are also viable if more than one half of the cotyledon from the

radicle end is bright red, if unstained parts do not include those that would develop

into roots (radicle) and shoots, or if only 1/3 or less of the radicle from the tip is

unstained. Percentage viability (V) is taken as percentage of seeds judged

germinable through TTZ and would reflect that of the original seedlot. It is

calculated as:

V = (No. of viable seeds) / (Total no. of seeds tested) x 100

Interpretation of TTZ results is subjective and needs considerable experience.

Viability estimated through TTZ is often slightly higher than actual germination.

SEED MOISTURE TEST

The amount of moisture in the seed determines how fast the seed deteriorates and

how long it can be stored Moisture determination is necessary, especially in seedlots

whose drying and/or storage history is unknown, to know if further drying is needed

before packaging, storage or shipping. The general rule is that seeds will have

approximately 12 percent moisture if dried for 2-3 days in the sun. Oven-drying with

controlled temperature is the most common technique to determine moisture but is

not practical at the farm level. Practical approximations of seed moisture include

biting (not recommended especially if seeds are treated), pinching or cracking of

seeds, depending on the species.
