| 摘 要： | 在对中国紫薇Lagerstroemia indica品种进行调查的基础上，根据形态特征选取调查品种中的51个紫薇品种和对照种南紫薇L. subcostata和福建紫薇L. limii，共计53个样品为分类运算单位，把数量分类学中的聚类分析方法应用于紫薇品种分类，探讨紫薇品种分类的等级和标准，建立完善的中国紫薇品种分类系统。Q型聚类分析的结果表明:将种系作为紫薇品种分类的一级标准，将花色作为紫薇品种分类的二级标准，这与传统紫薇品种分类的观点基本相符，说明分类结果具有一定的合理性。图1表2参6

| Abstract: | Based on the investigation of Lagerstroemia indica cultivars，according to their morphological features，51 Lagerstroemia indica cultivars，Lagerstroemia subcostata and Lagerstroemia limii were studied through the numerical taxonomy cluster analysis to build a complete Lagerstroemia indica classification system. Results of the Q cluster analysis indicated that germplasm source could be used as the first classification criteria and the flower color could be used as the second classification criteria. In accord with the traditional classification practice，the clustering results were reasonable.［Ch，1 fig. 2 tab. 6 ref.］ |
