摘　　要：研究利用植物血球凝集素(phytohemagglutinin,PHA)体内注射、肾细胞短期培养、空气干燥方法制备了驼背鲈染色体,并对其组型进行了分析。结果表明,驼背鲈的染色体组型公式是2n=48=48t,NF=48。结果显示,驼背鲈在鱼类系统演化上应属于高位类群,但在鲈形目中,其在进化上仍属相对原始的类型。The chromosome specimens of high-finned grouper Cromileptes altivelis were obtained from metaphase of kidney cells by in vivo injection of PHA and colchicine, hypatoic-air drying technique, as well as Giemsa staining. The results showed that C. altivelis had a diploid chromosome number of 48 and its karyotype formula was 2n = 48 = 48t, NF = 48. Its karyotype was in accordance with the typical characters of higher location karyotype group of fish, but yet a relatively primitive one in Perciformes.
