Collection, Storage and Treatment of Tree Seeds

A Handbook for Small Farm Tree Planters

Year of publication 1993

Pages 30

Product type Book (stand-alone)

Series number 1020-4490

Edition 1

Synopsis (short abstract) Farmer in Asia have become increasingly interested in planting trees on their farms, and on village public lands. The reasons for their growing interest are many: deforestation-many areas now lack easy access to tree products for household use; awareness-trees contribute to the environmental stability and productivity of small farms; demand-fast growing trees are an increasingly profitable investment. Users of this handbook will become familiar with few simple techniques which will enable them to be successful seed collectors. They will then be able to; develop improved village supplies of tree products for family and local use; plant trees as valuable crash crops; have greater access to tree seedlings which can be used to restore damaged environments.

    Storage of seed potatoes with the Diffused Light Storage (DLS) principle in Nepal 2011

    Seed constitutes a very important part of potato cultivation as it accounts for almost 50 percent of the total cost and it is the main source of diseases. In addition, unavailability of good quality seed potatoes at the right time is another problem in potato cultivation. Diffused Light Storage (DLS) principle meets the criteria for storing seed potatoes in the hill region at low or no cost, and it can be adapted to any existing on-farm storage. The DLS method is based on the use of natural indirect light and good ventilation or air flow, instead of low temperature, to control excessive sprout growth and associated storage loss. Provided that direct sunlight can be controlled, any kind of existing potato storage facilities can be converted into DLS. It is not necessary to build a new facility and any design used by farmers is good as long as the DLS-principle is adopted. The objective of this practice is to improve the quality of seed tuber through the DLS method.

    Recently, the role of sacred groves in biodiversity conservation and provision of ecosystem goods and services has been a subjected to scientific investigation. In this study, data were collected from four sacred groves (Osun‐Osogbo, Igbo‐Olodumare, Idanre Hills and Ogun‐Onire) in southwestern, Nigeria to investigate their volume yield, tree species diversity, biomass and carbon storage potentials. Data were collected from 32 sample plots of 20 m x 40 m, established across the four sacred groves. In each plot, all woody plants with dbh ≥10cm were identified and their growth variables (dbh and height) measured. Non‐destructive allometric equation method was adopted for the estimation of volume, biomass and carbon stock production. The number of families and tree species encountered in the groves (understory and overstory layers) ranged from 22 to 32 and 41 to 85, respectively. The four groves had high Shannon‐Wiener diversity index (2.63 ‐ 3.55). They had high volume yield (244.99 m3 ha‐1 to 343.08 m3 ha‐1), biomass production (87.8 t ha‐1 to 231.86 t ha‐1) and carbon stock (43.9 t ha‐1 to 115.9 t ha‐1), with potentials for continuous growth as evidenced by the presence of young trees in the lower canopy. Thus, besides being good biodiversity conservation method, sacred groves act as sink of atmospheric CO2 considering their high biomass and carbon accumulation. The use and protection of sacred groves by indigenous people has enhanced tree species diversity, improved carbon sequestration and production of other forests ecosystem goods and services, thereby mitigating climate change and its effects.
