测试了水稻和烟草两种叶片经不同剂量的60Co γ射线辐照处理后
组织电阻及离子外渗的动态变化情况。研究结果表明:当超过一定的剂量阈值后
随着辐照剂量的增加
两种植物的叶组织电阻均呈现先上升、后下降的变化规律;叶组织电阻的改变与离子外渗的变化趋势并不一致;用测量叶组织电阻的方法可以较灵敏地体现出植物对γ射线的动态反应情况。运用电生理学的基础理论对上述生理现象的产生原因从机理上进行了分析与探讨。
Leaves of rice and tobacco were irradiated by g-ray
and the dynamic change of electrical resistance and ion leakage of leaf tissue was studied. It is shown that
with the radiation dose rising
the leaf tissue electrical resistance for both plants rises firstly
and when the radiation dose exceeds a certain value
the resistance declines. But this change rule is different from the rule for ion leakage. And the method of measuring electrical resistance of leaf tissue can reveal the g-ray’s influence on plant more sensitively.
