摘    要:目的]比较大鳞副泥鳅雌雄个体的形态特征。方法]采用主成分分析与t检验方法,比较了大鳞副泥鳅雌雄个体的10个外部形态特征。结果]t检验结果表明,10个比值性状中有3个比值性状表现出极显著差异(P〈0.01),1个比值性状表现出显著差异(P〈0.05),其他性状差异不显著。主成分分析构建了4个主成分,贡献率分别为31.151%、18.844%、12.324%和10.169%,4个主成分的累积贡献率为72.487%,雌雄个体在主成分分析图上存在重叠交错态势,差异不显著,与t检验结论相一致。结论]该研究结果为大鳞副泥鳅的养殖提供理论基础。

关 键 词:大鳞副泥鳅  形态性状  主成分分析  t检验

Abstract:Objective] The aim was to compare the morphology difference between sexual dimorphism of Paramisgurnus dabryanus Sauvage.Method] The comparison of 10 morphological characteristics between sexual dimorphism of P.dabryanus was conducted with principal component analysis and t-test methods.Result] The results of t-test indicated that three of 10 morphological characteristics showed extremely significant difference(P<0.01)and one of 10 morphological characteristics was significantly different(P<0.05).Princip...
Keywords:Paramisgurnus dabryanus Sauvage  Morphological trait  Principal component analysis  t-test
