摘要：

以葛氏鲈塘鳢（Perccottus glenii）的鳃、肾及肠细胞为材料，用空气干燥法制片，用Leica显微镜进行观察，依据Levan等（1964）的分类标准进行其染色体的数目及组型分析。结果表明葛氏鲈塘鳢的染色体数目为2n等于44条，n=22。染色体总臂数(NF)为82。其中，亚中部着丝点染色体为18对，亚端部着丝点染色体为1对，端部着丝点染色体为3对。核型公式为2n=36sm+2st+6t。根据染色体形态分析的结果，没有发现性染色体的存在。

Abstract:

The Karyotype of Perccottus glenii was studied through the chromosome metaphase prepared from the cells of the gill、kidney and intestines by the colchicine-hypotonic-air drying technique and Giemsa staining.It was observed by Leica microscope.The analysis of chromosome Karyotype of Perccottus glenii was according to Levan’s standard.The result shows that the number of the Chromosome of Perccottus glenii is 2n=44,n=22. Its fundamental arm number(NF) is 82. Its karyotype comprises 18 pairs of submetacentric chromsome, 1 pair of subtelocentric chromosome and 3 pair of telocentric chromosome.That means 2n=36sm+2st+6t.According to the analysis of the conformation of the chromosome ,there is no sex chromosome existing.
