Book Description
Survival, total height, diameter at breast height (d.b.h.), and stem quality of sugar maple trees of different provenances were compared 25 years after establishment in north-central West Virginia. Provenances were from Michigan, Minnesota, West Virginia, Massachusetts, New Hampshire, Vermont, Maine, and Quebec, Canada. There were significant differences between provenances for all traits except stem quality. By provenance; total tree height ranged from about 49 to 37 feet; d.b.h. from 6.7 to 3.6 inches; and survival from 100 to 15 percent. The predictability of total tree height 25 years after establishment based on mean provenance height at age 2, 6, 10, and 15 years is discussed. Results suggest that juvenile height growth may be a good predictor of mature height performance, thus decreasing the need for rotation-length trials.

Book Description
Large numbers of sugar maple seed are dispersed every second or third year. Very little seed was damaged by insects or mammals prior to dispersal. The trapping methods used prevented major losses following seed fall. Seed production was positively correlated with tree diameter and density but not with age of seed trees.

Book Description
The purpose of our studies with sugar maple was to develop a method by which superior sugar producers could be vegetatively propagated and grown for use in studies designed to improve sugar yields. Because high sugar producers will ordinarily be selected from trees of tapping size, our studies were conducted on relatively large roadside sugar maples (fig. 1). Branches on a couple of young sugar maples less than 2 inches d.b.h. were also treated.
