摘要
以肾细胞为材料,采用秋水仙素-低渗-空气干燥法、How e ll的银染方法制作染色体标本.首次报道了言密鲈(Colisa lad ia)的核型和NOR s银染核型,研究结果表明言密鲈的染色体组型是2n=46=22m+6sm+8st+10t,具有1对A g-NOR s位于A组第2对的染色体的短臂端部.
Chromosome specimen of kidney cells were prepared by using low colchicines-concentration air drying method , Howell's Ag-NORs staining method. The karyotype , Ag-NORs of Colisa ladia were abserved. The result shows that the karyotype of Colisa ladia is 2n=46=22 sm+6 sm+8 st +10 t, one pair of Ag-NORs located on the short arm terminal of No. 2 of A group.
