Abstract

Flowering of Populus deItoides Bartr. occurred from early March to early April; differences between trees within stands accounted for 98 percent of the significant variation in dates. High correlation (r = .91 to .96) between 1963 and 1964 dates of individual trees indicated that trees within stands flower in a predictable sequence. Seed dispersal lasted from mid-May until late August, and most of the variation was accounted for by differences among trees. Moderate correlations (r = .49 to .84) were observed between 1963 and 1964 dispersal dates of individual trees.
