| 摘 要： | 描述了紫踵劈蚌(Potamilus alatus)贝壳外部和内部特征,并对紫踵劈蚌、三角帆蚌(Hyriopsis cumingii)和褶纹冠蚌(Cristaria plicata)进行了形态学比较。运用多变量形态度量学方法分析了3种淡水育珠蚌的形态差异。主成分分析构建了2个主成分,其中第一主成分的方差贡献率为66·90%,第二主成分的贡献率为33·10%,2个主成分的累计贡献率达到100%;采用逐步判别法,从11个比例性状中筛选出6个主要性状建立了3种育珠蚌的形态判别函数,其综合判别准确率达到100%。

| Abstract: | The valve morphology of American freshwater mussel Potamilus alatus was studied,and compared with Chinese freshwater pearl mussels Hyriopsis cumingii and Cristaria plicata.The principle components analysis was used to analyze the differences in three species,resulted in generating tow principal components.The contributory rates of two principal components were 66.9% and 33.1% respectively.Furthermore,six dominant features were selected from eleven ones by stepwise discriminating analysis,and were used to built the discriminating functions for three freshwater pearl mussels.The synthetic identification accuracy was also determined to be 100% in this study. |
