Foliage-Crown Development and Interaction in Quercus Gilva and Q. Acuta

In many natural forests, crown interactions occur among trees of various sizes (ages) and various species. Competition is greatly affected by size and species of interacting trees. Thus, an analysis should be made of interactions between trees of different species and different sizes. Interactions in a monospecific even-aged stand represent a special case, and can be inclused in this general situation. In this study, an interaction between trees of different species and sizes is examined by foliage-crown development, and a basic mechanism of foliage-crown interaction is presented
