摘　　要：以胸径、冠幅、枝下高、分枝角、通直度、叶片花色素苷含量6个性状为主要指标,在吉林省临江、汪清、湾沟、红石4个地点的天然群体中选择拧筋槭观赏型优树。在野外调查获得40株初选优树的基础上,采用主成分分析法对初选优树进行综合评价与筛选,最终确定观赏型优树19株。采用Pearson相关分析法对性状间相关性进行分析,结果显示:拧筋槭观赏性状间相关表现较弱,相关性未达到显著水平。Taking the 6 traits of diameter at breast height(DBH),crown width(CW),height under branches(HUB),branch angle(BA),straightness and leaf anthocyanin content(LAC)as the main indexes,the ornamental plus trees of maple(Acer triflorum)were selected from natural forests in Linjiang,Wangqing,Wangou and Hongshi in Jilin Province.On the basis of 40 primary select trees obtained from field investigation,the primary select trees were comprehensively evaluated and screened by principal component analysis,and 19 ornamental plus trees were finally determined.Pearson correlation analysis was used to analyze the correlation between characters.The results showed that the correlation between ornamental characters was weak,and didn't reach a significant level.
