A method to evaluate white spruce cone crops


, : A method to evaluate white spruce cone crops. Forestry Chronicle 54(2): 88-91

Analysis of cones from 14 stands in Manitoba suggested that seed yield and % seed soundness can be estimated from cone length, and regression equations are shown. Cone length was uniform on any one tree, and varied at random geographically. Prior to harvesting it is recommended that a max. of 10 cones are sampled from the top 2-3 m of 6-10 dominant trees in each stand.
