Variation in Diameter Growth of Red Maple Progenies Grown in Ohio, Michigan, and Minnesota
Significant variation in diameter (dbh) growth was found among 19-yr-old red maple progenies grown in Ohio, Michigan, and Minnesota, from seed collected in 50 provenances scattered throughout the species' range. Both the provenance of origin, and one-parent families within provenances, were significant sources of variation in all three plantations. The fastest growing trees in Ohio and Michigan generally were from north central or east central portions of the range, whereas the largest trees in the Minnesota plantation were from northern Maine, northern Michigan, northern Ontario, and northern Wisconsin. Trees from southern seedlots grew most slowly in all plantings. Average diameter growth rate of seedlings from the same provenance was most often similar in Ohio and Michigan; less consistency was found between Ohio and Minnesota and between Michigan and Minnesota. Provenances from near Bethel, Maine; Houghton, Michigan; Rhinelander, Wisconsin; and Chalk River, Ontario yielded trees which showed above-average growth in all three plantations. North. J. Appl. For. 10(1): 28-31.
