s:772:"TI Agroforestry tree seed production: production guidelines for seed orchards

AB Community-based forestry and agroforestry programs around the world reforest denuded lands, protect valuable watersheds and produce indispensable tree products for soil improvement and fodder. These programs begin planting operations with a commodity of small size but great importance-seed! Adequate supplies of high quality seed are necessary to grow high quality seedlings. Unfortunately, shortages of seeds are common and limit the success of many community-based tree planting programs. Any discussion about tree seed production must consider the saying “garbage in garbage out”. If you plant junk seeds you will inevitably harvest junk trees.
