Geographic Variation of Jack Pine (Pinus Banksiana Lamb.)
Ten traits were measured on 10-year-old jack pine grown at Cloquet, Minnesota, from seed collected from 90 provenances. The traits were examined by using analysis of variance and computing correlations for all combinations of 9 traits plus latitude, longitude, and elevation of the seed sources and cluster analyses using the D2 values from the Mahalanobis distance function. Results of the ANOVA showed that seed sources differed greatly for the 10 traits measured and results of the cluster analysis showed that populations can be geographically defined.
