| 摘 要： | 应用单因素方差分析、聚类分析、主成分分析和判别分析方法,对海州(HZ)、南浦(NP)、莱州(LZ)、莆田(PT)和汕尾(SW)等不同海域的5个菲律宾蛤仔(Ruditapes philippinarum)野生群体形态数据进行比较分析。单因素方差分析表明HZ群体在多个形态参数上与其它组差异显著;聚类分析显示HZ群体与其它组距离较大;主成分分析共提取2个主成分,贡献率为28.28%和20.77%,累计贡献率为49.05%,散布图表明HZ群体与其他组区分明显;建立了5个群体的判别函数,判别准确率P1和P2均为36.0%~80.0%,综合判别率为53.6%,HZ群体的判别率最高。以上结果说明HZ群体与其它4组形态差异显著。

| Abstract: | One-way Analysis of Variance(ANOVA),cluster analysis,principal component analysis and multivariate discrimination analysis were used to study the morphological variations of wild populations of Manila clam Ruditapes philippinarum from 5 sea areas of Nanpu,Haizhou,Laizhou,Putian and Shanwei.One-way ANOVA showed that the clams of Haizhou group were significantly different from those of other groups in many morphological parameters.Cluster analysis indicated that the populations of Nanpu,Laizhou,Putian and Shanwei were morphologically similar except for Haizhou population.Principal component analysis showed that 2 principal components had contributory ratios of 28.28%and 20.77%,respectively,with a cumulative contributory ratio 49.05%.The scattering diagram showed that Haizhou group differed remarkably from other groups.The discriminant functions of 5 groups were established.As results the discriminant accuracy rate was 36.0%-80.0%(P1,P2),with a total of 53.6%,among which the discriminant accuracy rate of Haizhou group was the highest.To summarize,Haizhou group was morphologically significant different from the other four groups.This study can be helpful for germplasm resources protection and hybrid breeding of Ruditapes philippinarum. |
