摘要
通过对引进的杉木无性系采用随机区组设计进行对比试验,测定苗期、林期的地径、树高。采用聚类分析和相关性研究,结果表明:杉木无性系的各年龄阶段性状差异显著,表现了无性系早期选择的可行性,确定推广的杉木无性系为98号,392号,318号,453号,108号,492号,250号。
A comparative experiment for imported clone Chinese fir breed by means of grouping randomly and measuring nursery peried、bottom diameter and tree height of the forest stage was used.This paper adopts cluster analysis and the research of correlation.The results show that the characteristics difference greatly based on the stand age of the clone Chinese fir breed,The feasibility of the early selection for clone Chinese fir breed showed number 98、392、318、453、108、492、250 were superior.
