| 摘 要： | 采用3种多元分析方法,对3个野生种群和1个养殖种群的13个形态比例参数进行比较研究。聚类分析结果表明,广东湛江和海南临高的种群形态最接近,福建厦门种群的趋异程度最大。主成分分析构建了6个主成分,其贡献率分别为:第1主成分23.084%,第2主成分17.976%,第3主成分15.321%,第4主成分13.84%,第5主成分12.707%,第6主成分7.770%,累积贡献率为90.699%。逐步判别选入6个贡献率较大的性状进行判别分析,F检验结果显示,4个种群形态差异显著(P0.01);同时建立了4个种群的判别函数,其判别准确率P1、P2均为100%。综合判别率为100%。3种多元分析结果均认为,4个种群日本囊对虾在形态上已产生一定程度的差异,且集中表现在体重、头胸甲的性状上。

| Abstract: | Morphological differences among four groups of Marsupenaeus japonicus were studied with 13 morphological parameters using three multivariation analysis methods (cluster analysis, discriminant analysis, and component analysis). Cluster analysis showed that clams from the Guangdong Zhanjiang and Hainan Lingao population were rather similar in morphology, whereas the Fujian Xiamen population differed greatly from other populations. Through principal component analysis, six principal components were established, with their contributory rates being 23.084%, 17.976%, 15.321%, 13.84%, 12.707%, and 7.770%, respectively, and the cumulative contributory rate being 90.699%. The stepwise discrimination analysis revealed that the four populations differed significantly in morphology (P<0.01). Further, the discrimination functions of the four populations were set up, the discrimination accuracy being 100% for both P1 and P2, and the integrative discrimination accuracy being 100%. The overall results indicate that blind seed selection is relevant to the miniaturization of the cultured population, and that there are some morphological differences among the four populations, e.g. characteristics of carapace. |
