| 摘要: |
| 采用根尖压片法制片镜检观察药用植物山豆根(Sophora tonkinensis Gapnep.)体细胞染色体数目,并进行核型分析。结果发现山豆根的染色体数为2n=18,未发现非整倍性变异和多倍现象,也未发现B染色体,核型公式为K(2n)=18m,按Stebbins的核型分类标准,属于1A类型。 |

| Abstract: |
| The chromosome of Sophora tonkinensis Gapnep.was observed by the root tip pellet method.And its karyotype was analyzed.It was found that the formula was K (2n)=18m and the type was 1A in the standard of Stebbins.The aneuploidy, polyploid and B chromosome are not found in the observation. |
