| 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. |
| Keywords: | chromosome karyotype analysis medicinal plant |
