Eastern White Pine Cone and Seed Maturity in the Southern Appalachians
Tests over a 4-year period with eastern white pine in western North Carolina indicated that cone and seed maturity could not be accurately determined by specific gravity, but cone moisture content appeared to be directly related to both. A moisture content of 200% (dry weight basis) indicated maturity of both cones and seeds. After-ripening of cones for 4 weeks improved both seed yield and quality. Moist cone storage was helpful only if immature cones were collected. Dry cone storage provided seeds of high viability over the entire collection period. North. J. Appl. For. 5:172-176, Sept. 1988.
