不同壳性状虾夷扇贝体腔液三种酶活力的比较

Comparison of Three Coelomic Fluid Enzymes Activities in Scallop Patinopecten yesoensis

研究利用生物化学方法对不同壳性状虾夷扇贝体腔液中超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和过氧化物酶(POD)活力进行比较分析。结果表明,不同贝壳形态的虾夷扇贝,其体腔液中SOD、CAT和POD 3种酶活力不存在著性差异(P>0.05);不同壳色虾夷扇贝体腔液中,SOD和CAT酶活力存在显著差异(P<0.05),而POD酶活力差异并不显著。研究结果显示,虾夷扇贝的贝壳形态与其体腔液中抗氧化酶活力高低不存在相关性,而虾夷扇贝贝壳的壳色性状与其体腔液中抗氧化酶SOD和CAT活力高低存在一定的相关性。研究结果可为深入研究扇贝贝壳性状积累一定的理论数据,同时也对扇贝的良种选育具有一定的指导意义。

In order to find the relationship between immune-related enzyme activities and shell traits in scallop Patinopeeten yessoensis, superoxide dismutase（SOD）, catalase（CAT）, Peroxidase（POD） activities of coelomic fluid were examined and co and POD activities among different mpared. From our study, there is no significant difference in SOD, CAT shell sizes. However, for P. yessoensis in different shell colors, the difference in SOD and CAT activities of coelomic fluid between brown and white is significant （P〈0.05）, while there is no significant difference in POD activities. Our results suggested that shell color is to some degree correlated with SOD and CAT activities. This study has enriched our knowledge of scallop shell traits and can provide a new direction of scallop selective breeding.
