Seedlings of Populus balsamifera L., Liriodendron tulipifera L., Ulmus americana L., and Acer rubrum L. were grown in a fiberglass greenhouse. Total dry weight after 20 weeks was, (a) proportional to the percentage of dry matter allocated to leaf production, (b) relatively little affected by differences in seed size and net assimilation rates and (c) inversely related to the shade tolerance of the species involved.
