摘　　要：以哲罗鱼(Hucho taimen)肾细胞为材料,采用胸腔注射PHA和秋水仙素溶液,空气干燥法制备了染色体,姬姆萨染色和核型分析。结果表明,哲罗鱼的二倍体染色体数目为2n=84,核型公式为:2n=18m+16sm+34st+16t,NF=118。The metaphase chromosome of Hucho taimen was prepared from head kidney by PHA and colchicine injection and hypatoic -air drying technique, as well as Giemsa stai- ning. The karyotype was analyzed. The results showed that Hucho taimen had diploid chromo- some number of 84, and the karyotype formula was 2n = 18m ＋ 16sm ＋34st ＋16t ,NF =118 .
