Abstract:

Bigleaf maple is a common hardwood in western Oregon and Washington. Stored seeds from this species are generally believed to lose viability within a few weeks. In this study, two experiments were conducted with seeds collected in 1986 and 1987 in the Oregon Coast Range west of Corvallis, OR. Seeds collected in 1986 had a field moisture content (percentage of dry weight) of 49% and in 1987, 16%. The viability of the seed with the lowest moisture content declined from 75 to 60% during 1 year of storage at 1°C; the seed with the highest moisture content declined from about 90 to less than 10% viability. Storing the seeds at -10°C did not increase viability. Stratification of seeds for more than 60 days did not appear to increase germination. West. J. Appl. For. 5(2):52-55, April 1990.
