Abstract

Northern red oak acorn production was measured in 21 maturing stands on good sites in northwestern Pennsylvania. The number of acorns produced per acre varied from a low of 7,000 to nearly 273,000. Acorns were produced in all years. In no year was there consistently good acorn production at all areas, nor was there a good crop for more than two consecutive years at any location. Freezing temperatures when oaks were in flower was a major factor affecting acorn production on the Allegheny Plateau.
