| 摘 要： | 应用SAS统计软件,对107个苎麻品种的头麻纤维线密度、断裂强力等11个指标进行主成分分析,按累计贡献率大于或等于90%选出前3个主成分。在此基础上对这107个苎麻品种进行聚类分析,将其聚为4类,类群Ⅰ和类群Ⅳ综合物理性能中等,类群Ⅱ综合物理性能较好,类群Ⅲ综合物理性能较差。

| Abstract: | The principal component analysis of 11 physical property indexes such as fineness of fiber,breaking strength of 107 ramie varieties was undertaken using the statistical analysis system(SAS).Three principal components were chosen according to the criteria of cumulative contribution root≥90%.The 107 ramie varieties were cluster analyzed on the result of principal component analysis,and these varieties were divided into four clusters.In terms of comprehensive physical properties,cluster Ⅰ and Ⅳ: moderate;cluster Ⅱ: fairly good;and cluster Ⅲ: relatively poor. |
