Effective Stratification of Spruce Pine Seed

Spruce pine (Pinus glabra Walt.) seeds are dormant and require stratification for fast, complete germination. For up to 28 days, both total germination and speed of germination increased as the stratification period lengthened; extending the period to 56 days improved speed only. Interest in this species is increasing am-mg landowners because of its rapid growth and value for pulpwood or sawtimber. Little has been known about the germination characteristics and stratification needs of the seeds. This article reports effective stratification times.
