Geographic Variation of Red Pine Survival, Growth and Productivity in a Minnesota Field Test

Forty-eight red pine ( Pinus resinosa ) seed lots from various geographic origins were evaluated after 25 years for survival, tree height, diameter, total volume and volume produced per acre. Differences in seed lot means were of statistical significance for all growth variables and of practical significance in the case of volume per acre produced. Seed lot means were positively correlated with longitude, although specific seed lots from eastern longitudes were very productive. Age-age correlations indicated that height and diameter at age 17 accounted for 40 and 50 percent of the variation among seed lot means in volume produced per acre at age 25. Additional keywords: geographic variation, volume productivity, age-age correlation, Pinus resinosa .
