  • In our study,the head kidney tissue were used as materials,and in vivo treatment by phytohemagglutinin（PHA） and colchicines and Giemsa staining were performed,and the cytogenetics of E.trimaculatus were analyzed.The results indicated that the karyotypic formula of E.trimaculatus was 2n=48,48t,NF=48,no heteromorphic chromosome was detected.Based on the karyotypes of 23 species of groupers,the conclusion that 2n=48,48t,NF=48 was the primitive cytogenetic characterization of genus Epinephelus were proposed.

Abstract: In our study,the head kidney tissue were used as materials,and in vivo treatment by phytohemagglutinin（PHA） and colchicines and Giemsa staining were performed,and the cytogenetics of E.trimaculatus were analyzed.The results indicated that the karyotypic formula of E.trimaculatus was 2n=48,48t,NF=48,no heteromorphic chromosome was detected.Based on the karyotypes of 23 species of groupers,the conclusion that 2n=48,48t,NF=48 was the primitive cytogenetic characterization of genus Epinephelus were proposed.
