| 摘 要： | 利用系统聚类分析法，依据一年生杏嫁接苗株高、茎粗、主干电阻率、POD活性及ABA含量5项指标，对参试砧木进行预选，初步选出了17株对杏具有矮化效应的砧木，表明利用系统聚类法，依据综合指标，有可能实现具有矮化效尖的单株的选择。

| Abstract: | According to the five growing indices of apricot grafted seedings, Hierachical Clustering Methods were used for pre-selecting dwarf rootstocks of apricot from attended rootstocks. The preliminary results showed that it was possible to make pre-selection of single dwarf rootstock from 17 rootstocks selected,using Hierachical Clustering Methods and according to the complex indices. |
