STORAGE OF HARDWOOD TREE SEEDS

摘要

Large quantities of high-quality seed are required annually for artificial regeneration. Although programs for the production of improved seed by seed-production area and seed orchard have been initiated in several provinces, it will be some years before mass production of such seed balances the demand. Meanwhile, because of the lack of uniformity and predictability of cone and seed crops, bulk quantities of seeds are collected in good seed years and stored for use in intervening years to ensure a continuous supply of seed for the annual production of planting stock and direct seeding.
