摘　　要：为了解波纹唇鱼(Cheilinus undulates)的细胞生物学特征,采用植物血凝集素PHA、秋水仙素腹腔注射和空气干燥制片法以头肾组织为材料,对波纹唇鱼的染色体核型进行了研究。结果表明,波纹唇鱼具有染色体48条,核型公式为2n=48=6m+42t,NF=54,未发现随体、次溢痕及性染色体,其核型符合典型的高位类群鱼类核型特征。To explore the cell biological characters of Cheilinus undulates, we analyzed the karyotype of C. undulates from their renal tissues by the PHA and colchicine injection-air drying method. The results showed that there were 48 chromosomes in C. undulates and its karyotype formula was 2n=48=6m＋42t, NF=54. Satellite chromosome, secondary constrictions and sex chromosome were not found in C. undulates. The karyotype of C. undulates is in accordance with the higher group of fish evolutionary taxonomy.
