摘要
用不同剂量60Co-γ射线急性辐射处理整株粉掌铁兰后,测定不同处理叶片的酶活力。结果显示:粉掌铁兰的SOD活力均比对照降低,CAT活力的变化不大;POD活力的含量均比对照提高;PPO的活力10 Gy处理的比对照降低,其它处理与对照相比均有所提高,其中80 Gy处理的上升最多。辐射剂量与PPO活力呈极显著正相关,其相关系数为0.974。
Tillandsia cyanea was treated by irradiated dosages of 60Co-γray to determine the some enzyme activity of leaves. The result showed that SOD activity was decreased, CAT activity was not changed, POD was increased, PPO activity was decreased at 10 Gy, It were increasable in other dosages, It was maximal at 80 Gy. It was significantly positive correlation between radiation dosages and POD activity, correlation coefficient 0.974 .
