摘  要:
通过对人工林20个杨树无性系的胸径和树高生长进行比较,结果显示中驻6号胸径生长量明显优于其他所有无性系,其次是50杨、桑迪;树高生长具有极显著差异,生长量最大的为中驻6号和102,均为11.3 m,生长量最小的为I107,只有8 m。各系号胸径和树高的生长均存在一定的相关性。

摘  要:
Twenty clones of poplar plantation in DBH and tree height growth were compared.Among them,the DBH growth of Zhongzhu 6 was significantly better than that of all other clones,followed by the 50 Poplar,Sandy.Tree height growth had very significant difference,with the highest of Zhongzhu 6 and Poplar102 in growth(11.3 m),and the lowest growth for CL.Ⅰ107(only 8 m).And there were certain correlations between tree height and DBH growth of all the clones.
