摘　　要：本文在定期观测引种的81个杨树无性系苗期生长量的基础上,运用DPS软件对引种的81个杨树无性系的扦插成活率、I级苗率进行系统聚类分析,结果表明:81个杨树无性系分成3种类型,第2类的17个无性系表现优良。17个杨树无性系早期生长统计分析结果,杨树无性系以14、65、41、43、44和32生长较好。In this paper the cuttage survival rates and percentage of Class Ⅰ cuttings of the 81 poplar varieties were analyzed systematically with DPS software based on the observation of their growth increments in the seedling stage The results showed that the 81 poplar varieties could be classified into 3 groups, with the 17 varieties in GroupⅡ showing good characteristics. The early growth statistical results of the 17 poplar varieties showed that the vaieties 14,65,41,43,44 and 32 grew better compared with others.
