Abstract

The architecture of 48 eastern deciduous trees was examined using five characteristics: leaf size, leaf shape, twig cross-sectional area, leaf number per twig, and branching density. Although there was much intraspecific variability in these characteristics, broadscale interspecific trends were evident. As leaf size increased, the percentage of trees with lobed, and then compound, leaves increased, but simple, unlobed leaves ranged throughout. An allometric series of architectural forms resulted from correlations between three of the variables: as leaf size increased, twig cross-sectional area increased, and branching density decreased. This lends empirical support to "Corner's Rules," first formulated for tropical trees. Shade intolerant trees had more leaves per twig and bore a given total leaf area with fewer first-year shoots than shade tolerant trees. These data suggested that early successional trees bear their photosynthetically active tissue with lower investment in supportive, generally non-photosynthetic, tissue.
