摘要

Flowering and seed production of selected trees in northwestern Pennsylvania and southwestern New York were rated visually for several years. The seed crops of white ash and sugar maple were closely related to the amount of flowering, and flowering can be used to predict seed crops in those species. Consistency of seed production in species and individuals, and other aspects of seed production are discussed.
