Impact of Storage on Viability of White Spruce Seed

Simpson, D., Daigle, B., and Hayes, D. Tree Planters' Notes 52(2):4-8. 2008.

Samples of seed of white spruce (Picea glauca [Moench] Voss) from 36 individual trees, collected in 1974 from 5 provenances in Ontario, Canada, were placed in frozen storage at -20 ˚C (-4 ˚F) in 1977 and in storage at 4 ˚C (39 ˚F) in 1982. Seed was removed from both storage temperatures and tested in 2002 and 2005. Seed moisture content increased on average, whereas average germination remained the same or declined slightly after storage at -20 ˚C (-4 ˚F) for 25 and 28 yr.
