Viability of White Pine Seed After 10 Years of Storage
Abstract:Good crops of eastern white pine seed occur at intervals of three to five years. Nursery seedings during intervening years are, therefore, dependent upon stored seed. Because of its high oil content, the seed spoils easily and hence requires careful storage. On the basis of a study of five temperature conditions and five moisture levels, the author recommends that white pine seed be dried down to a moisture content of at most 7 percent; and then stored in moisture-proof containers at a temperature of 36°F. Under these conditions viability should be fully retained for at least ten years.
