| 摘要: |
| 测定实验表明:位于四棱豆植株中部节位叶片中的SOD活性高于植株下部和上部节位叶片中的SOD活性;而位于下部节位豆荚和种子中的SOD活性要高于位于上部节位豆荚和种子中的SOD活性,且随着结荚部位升高,SOD活性呈降低趋势. |

| Determination on Superoxide Dismutase Activity of Psophocarpus tetragonolobus Organs at Different Nodes |
|
|
| Abstract: |
| The experiment showed that the SOD activity in middle node leaves of Psophocarpus tetragonolobus was higher than that in lower and upper ones. The SOD activity in the pods and seeds at lower node was higher than that in the upper ones. The SOD activity in Psophocarpus tetragonolobus pods and seeds decreased as the node position rose. |
| Key words: Psophocarpus tetragonolobus node organ superoxide dismutase |
