Deterioration of Black Spruce Seed During In-Situ Storage and Processing

Cones of four age classes were collected from 65 individual black spruce (Picea mariana (Mill) B. S. P.) trees. After three extraction cycles for each cone lot, germination tests were conducted. Seed from older cones exhibited somewhat lower germinative capacity, but extraction procedures did not reduce total viability. However, reduced germinative energy was exhibited by seed of older cones and by seed recovered from second and third extraction cycles. Implications for subsequent production of different stock products are discussed. Tree Planters' Notes 40(3):5-8 ; 1989.
