| 摘 要： | 运用3种多元分析方法,对黑龙江泥鳅MIsgurnus mohoity、北方泥鳅Misgurnus bipartitus和泥鳅Mis-gurnus anguillicaudatus的11个形态参数进行了综合分析。聚类分析结果表明：北方泥鳅和泥鳅聚类,亲缘关系较近,与黑龙江泥鳅群体的亲缘关系较远。主成分分析结果表明：主成分1的总方差贡献率为50.430%,主成分2的为20.880%,主成分3的为10.381%,累积贡献率为81.691%。判别分析结果表明：建立的3种泥鳅的判别函数,判别准确率P1为71.4%~100%,判别准确率P2为71.4%~100%,综合判别率为80.8%。

| Abstract: | Eleven morphometrical items were measured to evaluate the morphological variations in Amur weatherfish Misgurnus mohoity,northern weatherfish Misgurnus bipartitus and oriental weatherfish Misgurnus anguillicaudatus by three methods of multivariate analysis.Cluster analysis showed that northern weatherfish was close to oriental weatherfish,and distantly related to Amur weatherfish in genetic relationship.The principal component analysis revealed that the contributory ratio was 50.430% for the principal compo... |
