Abstract: The relationship between leaf area of crown(L. A. C.) and growth indices in a poplar plantation had been investigated from 1983 to 1986. The leaf area of crown and the volume increment raise with the increasing of water supply. The leaf area of crown is highly correlated with height(H), diameter(D), volume(V) and D2H of the tree. The heighest correlation is presented between leaf area of crown and volume (D2H). Some related problems were discussed in this paper.

Key words: Leaf area, Growth index, Growth analysis
