| 摘要: |
| 用聚丙烯酰胺凝胶电泳法分析麝香石竹(Dianthus caryophylus L.)切花的超氧物歧化酶(SOD)、过氧化物酶(POD)同工酶,结果表明保鲜剂可使SOD的活性增强,能保持SOD酶带不缺失和出现新的酶带;使POD活性比对照减弱。保鲜剂对SOD同工酶的影响比POD同工酶明显;对不同器官的酶活性和其同工酶有不同的效果。 |

| Abstract: |
| The isoenzyme of superoxide dismutase (SOD) and peroxidase (POD) in the cut-flower of carnation (Dianthus caryophyllus L.) were analysed by PAG electrophoresis. The results showed that the activiy of SOD was higher than that of the control, new isoenzyme bands of SOD appeared in some organs of the cut-flower, after 48 days treated by the antistaling agent. The treatment of antistaling agent could decrease the activity of POD as compared with the control. The effect of antistaling on isoenzyme of SOD was more remarkable than that on isoenzyme of POD. For different organs, the antistaling had different effects on isoenzyme. |
