Abstract

The production of flowers and seeds of black cherry, red maple, sugar maple, and white ash and their relation to advance regeneration were observed from 1971 through 1976 on the Allegheny Plateau of northwestern Pennsylvania. There were good seed crops 1 year out of 2 for black cherry, 1 year out of 3 for red maple, and 1 year out of 6 for sugar maple. No white ash seed was produced. Flower crops were reliable indicators of seed crop size for the maples but not for black cherry. Both seed production and advance regeneration were related to basal area. Advance regeneration and basal area data were used to develop a guide to evaluate the adequacy of seed sources for the regeneration of Allegheny hardwood stands.
