| 摘 要： | 对6个剂量氩离子处理条件下北方粳稻根系过氧化物酶(POD)活性和POD同工酶聚丙烯酰胺凝胶电泳分析表明:不同水稻品种间有辐射敏感性差异。随氩离子诱变剂量的增加,3个水稻品种根系POD活性的值都明显高于对照,在3000剂量时的POD值最大。在处理剂量范围内,POD活性随剂量的变化表现出先升后降的变化规律,且有一定的波动性。而且农大7各处理酶谱活性差别最大,秋田小町和农大13酶谱差别较小,但在3000系数剂量下酶带有不同程度加深的趋势。 |

| Abstract: | The effect of Ar~+ injection at six different dosages on peroxidase(POD)activity and isoenzyme expression of japonica rice was analyzed by using polyacrylamide gel electrophoresis.The results showed that the sensitivity of three rice varieties to ion implantation were different as the dosage increased.The POD activity of the injected rice was higher than that of the control and the value at 3000 dose was the highest.It at first in- creased and then decreased as the dosage increased at the tested range.The diversity of enzymogram band of‘Nongda 7’was broader than that of‘Nongda 13’and‘Qiutianxiaoding’,but the band color at 3000 dose showed darker than that at other dosages. |
