| 摘要: |
| 二倍体马氏珠母贝为广西北海野生贝,2龄~3龄。三倍体马氏珠母贝用6-DMAP诱导获得,1.5龄。核型分析结果,二倍体2N=28,核型公式为7M+3SM+3ST+1T,NF=48;三倍体3N=42,核型公式为7M+3SM+3ST+1T,NF=72。染色体按Levan等人的标准分类。 |

| Abstract: |
| The diploid individuals of Pinctada martensii aging 2 to 3 years old were wildness,and collected in Beihai,Guangxi.The triploid ones aging 1.5 years old were obtained by induction of 6-DMAP from the diploids.The karyotype is as follows:2N=28, the karyotype formula is 7M+3SM+3ST+1T,NF=48. 3N=42,the karyotype formula is 7M+3SM+3ST+1T,NF=72. The chromosome was classified on the criteria of Levan et al. |
