杉木优良无性系早期生长性状和侧枝发育特征的比较
Comparison analysis of early growth traits and lateral branch development characteristics of fine clones of Chinese fir
[目的]为探究不同杉木无性系早期生长性状与侧枝发育特征的差异,早期筛选适合杉木大径材和无节材培育的优良无性系。[方法]选取福建省顺昌埔上林场的 12 个 3 年生洋系列无性系为研究对象,并以埔上林场培育 2 代、3 代实生苗为对照,连续两年进行树高、地径、侧枝节间距、侧枝长度、侧枝基径、侧枝角度、侧枝数、冠幅高度和冠幅面积等调查分析。[结果]不同杉木无性系生长性状与侧枝发育特征存在显著差异(p<0.05)。其中,洋058 和洋064的树高和…查看全部>>
