摘　　要：以星突江鲽Platichthys stellatus Pallas头肾细胞为材料,采用PHA和秋水仙素活体注射体细胞体内培养法,经空气干燥制备了染色体并对其染色体核型进行分析。结果表明,星突江鲽的染色体数目为48条,包括46条端部着丝粒染色体和两条亚中部着丝粒染色体,未发现异型染色体对和随体。核型公式为:2n=48,2sm+46t,NF=50。The karyotype of Platichthys stellatus was prepared for its head kidney by PHA , colchicine injection and air drying method. The karyotype was analyzed. The results showed that the chromosome number of the species was 2 n=48, including 46 telocentric chromosomes and 2 sub-middle chromosomes and there was no visible evidence of the heterotypical chromosome and satellites. The karyotype formula was 2 n=48,2 sm＋46 t,NF= 50.
