摘　　要：文章通过分析2003年广东省所选樟树优树的生长与叶果性状,从多个角度证明了5株优势木法选出的樟树优树是合理的,大部分数量指标完全超过5株优势木,樟树优树的叶果性状在个体及种源间均呈极显著差异。动态聚类分析显示樟树优树叶果有7种类型,其中长叶重圆果型、圆叶轻圆果型和圆叶重圆果型较多,分别占所选优树的23.0%、41.4%和23.0%。This paper analyzed the growth, leaf and fruit traits of Cinnamomum camphora superior trees, selected from Guangdong province in 2003, and studied the traits of its leaves and fruits. The results show that ： It is effective to select superior tree based on 5 dominant trees comparison. Variance analysis about the traits of the leaves and fruit shows that the differences were very significant between the superior trees and provenances. Dynamic clustering analysis shows that there are 7 kinds of leaf-fruit type.
