White Spruce: The Effect of Long-Term Cold Storage Is Partly Dependent on Outplanting Soil Temperatures

Seedlings of Picea glauca were freezer stored for 0 to 30.5 wks. at -5C, and thereafter grown at three different soil temperatures (3,7,11C). Root growth at 11C increased as seedlings received up to 14 wks. storage duration, and decreased thereafter. In contrast, root growth at the lower temperatures simply decreased with storage duration. Root growth performance and stomatal conductance data both suggest that storage duration greater than 22 wks. can be detrimental to seedling development.
