Abstract

Dormancy and germination requirements for white spruce (Picea glauca [Moench] Voss) seeds collected from 1970 to 1982 from single trees and in bulk at latitudes 43 to 62 N across Canada were evaluated. Results indicate that dormancy varied among latitudes and crop years. For laboratory germination testing, 21 days of moist chilling effectively released dormancy and enhanced germination.
