摘要
为了给叶用喜树栽培提供科学与实践依据 ,采用 1 6个喜树地理种源的 1年生壮苗上山造林和苗床截干 2种处理方法 ,测定幼树和萌芽条的生长量。结果表明 :幼树高生长量第1名至第 5名依次为湖南长沙、福建屏南、湖北武昌、浙江丽水和浙江临安种源 ,根径与树高间相关系数以贵州贵阳种源最大。截干后萌芽条总的萌芽率为 69 3% ,第 1名至第 5名依次为浙江临安、浙江开化、浙江丽水、江苏南京林业大学和安徽东至种源 ,萌芽条的根径与高生长间相关性都呈紧密相关。表 7参
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 on matted 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.
