| 摘 要： | 本文首次报道了真鲷和黑鲷的染色体组型:真鲷二倍体数2n=48,除第l对为亚端部着丝点染色体外,其余全部为端部着丝点染色体,臂数NF=48;除第2对与第3对染色体之间、第20对与第2l对染色体之间差异显著外,其余每相邻两对染色体间均无显著差异。黑鲷二倍体数2n=48,3对为中部、2对为亚中部着丝点染色体,其余全部为端部着丝点染色体,臂数NF=58;前5对染色体中,每相邻两对染色体之间有显著差异,在第6对至第24对端部着丝点染色体中,除第23与第24对染色体之间有显著差异外,其余每相邻两对间无显著差异。

| Abstract: | The karyotypes of the two sparid fishes, Pagrosomus major (Temminck et Schlegel) and Sparus macrocephalus (Basilewsky), were studied through the chromosome preparations obtained from their kidney cells by the method of PHA and colchicine injection. Slides were made by the air-drying technique with Giemsa staining.Pagrosomus major (Temminck et Schlegel) has a 2n of 48, consisting of 1 pair of subte locentric chromosomes and 23 pairs of telocentric chromosomes. NF = 48.Sparus macrocephalus (Basilewsky): 2n = 48, consisting of 3 pairs of metacentric chromosomes, 2 pairs of submetacentric chromosomes and 19 pairs of telocentric chromosomes NF = 58.There were no sex chromosome and othe'r unusual chromosomes found in both species. Some problems concerning the taxonomy and chromosome polymorphism were discussed. |
