Abstract

In order to provide the scientific basis for the practice of leaf-used Camptotheca acuminata , two treatment methods , i .e .plantation test on hills and cutting trunk test onmatted beds , were adopted for the annual sound seedling from 16 Camptotheca acuminata provenances .Increments of young trees and sprouting branches were measured .The test results indicated that the provenances in Changsha of Hunan , Pingnan of Fujian , Wuchang of Hubei , Lishui of Zhejiang and Linan of Zhejiang demonstrated a tree height increment ranking from first to fifth .The provenance in Quiyang of Quizhou had a maximum correlation coefficient between height and base diameter of young trees .The sprouting branches after cutting trunk had a total sprouting percentage of 69.3 %. The provenances in Linan of Zhejiang had the highest sprouting percentage , followed in order by those in Kaihua of Zhejiang , Lishui of Zhejiang , Nanjing Forestry University of Jiansu and Dongzhi of Anhui .A close relation was observed between height and base diameter increment of sprouting branches .
