摘　　要：比较了不同地理品系褶皱臂尾轮虫Brachionus plicatilis的形态和同工酶差异,并结合生活史参数初步探讨了不同地理品系轮虫的亲缘关系。结果表明:不同地理品系褶皱臂尾轮虫形态差异显著,并且在同工酶上也有明显的变异;基于形态测量和同工酶分析的两次聚类结果较为一致,表现为内蒙和西藏品系轮虫亲缘关系较近,辽宁、大连、天津和山东品系轮虫亲缘关系较近;基于生活史参数的聚类分析与以上结果有较大出入,表明生活史参数在亲缘关系研究中的局限性。The morphology and isozyme of six geographical rotifer （Brachionus plicatilis） strains were examined and the relationship among the rotifer strains were compared by morphometry and isozyme eletrophoresis, combined with life history. The results showed that different rotifer strains had significant difference in morphology and obviously differentiation in isozymes. The cluster analysis of morphology and isozyme indicated that there was a close relation- ship between Neimeng and Xizang rotifer strains and among Liaoning, Dalian, Tianjin and Sandong rotifer strains. The cluster analysis of the life history revealed that the life history characters were not suitable in similar studies.
