| 摘 要： | 通过胸腔注射PHA及秋水仙素,取头肾细胞,经空气干燥法制片,Giemsa染液染色,观察了笛鲷属的约氏笛鲷（Lutjanus johni）、勒氏笛鲷（L.russelli bleeker）、画眉笛鲷（LLutjanus vitta）的染色体核型进行分析研究,结果表明：染色体数目2n=48,染色体总臂数（NF）为48,核型公式为48t.

| Abstract: | The paper reports the karyotypes of Lutjanus johni, Lutjanus russellia nd Lutjanus vitta through the chromosome metaphase prepared from kidney cells by the PHA colchicine-- hypotonic--air drying technique and Giemsa staining. The chromosome numbers of Lutjanus johni, Lutjanus russelliand lutjanus vitta were found to be 2n=48, which is telocentric chromosome, and the karyotype formula is 2n=48. Its fundamenal arm number (NF) is 48. |
