Study on Plant Architecture of Cunninghamia lanceolata Based on Measured Data

LU Kang-ning; ZHANG Huai-qing; LIU Min

Based on plant architecture,this paper analyzes the morphological structure of four Cunninghamia lanceolata trees in different ages using statistical method .The results indicate that: the bifurcation ratios increases with the age; the branching angles of primary branches are mainly distributed from 50° to 100° while the secondary branches are mainly distributed from 50° to 80°; the azimuth of primary branches follows uniform distribution and the secondary branches mostly distribute in horizontal direction; Distance from a branch attachment region to its parent container has a good correlation with the branch length. Branch length has a great relevance to the number of sublevel branch.
