Effects of Extended Prechilling on Laboratory Germination and Fungal Infection in Seeds of White Spruce and Eastern White Pine
Prechilling treatments of up to 15 weeks did not show any detrimental effect on laboratory germination of Picea glauca (Moench) Voss and Pinus strobus L. seed. Infection was generally greater on germinants of treated seed than on those of untreated seed, but fungal infection of germinants did not increase with the duration of prechilling treatment. Differences in infection between treated and untreated seed could be due to the spread of infection among seed during the moist prechilling period.
