| Research Abstract |
Branch position move through branch distortion was less than 10cm. Marginal branch in crowns moved more than central one.
The maximum shoot length at crown top shoot population decreased with tree height. The maximum shoot length of young trees are about 50 cm in most species both in warm and cool Temperate Zone.
Shoot population growth rate also decreased with tree height. However, it correlated with shoot length rather than tree height or stem diameter.
Tree interaction model reproduced the similar pattern to warm-temperate evergreen broad-leaved forest. Foliage density was high at upper canopy and it correlated to vertical species distribution. Species with tall maximum height and highest shade tolerance got the largest dominance. The foliage-height patterns of tropical rain forest was not reproduced.
The decrease of maximum shoot length at crown top in large trees seemed to be a major reason for species specific maximum tree height.
