厚朴叶片衰老过程中SOD对叶绿素、蛋白质及质膜透性效应的定量研究

A QUANTITATIVE STUDY ONTHE EFFECT OF SOD ACTIVITY ON CHLOROPHYLL,PROTEIN AND PERMEABILITY OF PLASMA MEMBRANE DURING LEAVES SENESCENCE OF OFFICINAL MAGNOLIA

本文应用弹性分析和边际分析数学方法对离体厚朴叶片衰老中的SOD活性对叶绿素、蛋白质及质膜透性效应进行了研究。结果表明:厚朴叶片衰老中,SOD活性对叶绿素或蛋白质或质膜透性的边际量和弹性系数的效应,是随着外源营养条件和温度变化而变化的。SOD活性与叶绿素及蛋白质的弹性系数呈显著正相关,SOD对它们的效应处于递增阶段,而SOD活性与质膜透性的弹性系数呈显著负相关,其效应处于负效应阶段。

This paper deals with a quantitative analysis of the effect of SOD activity on chlorophyll, protein and permeability of plasma membrane during detached leaves senescence of Officinal magnolia by using mathematics methods (productive elasticity and marginal yield). The result showed that the effects of SOD activity on marginal yields and productive elasticities of chlorophyll, protein and permeability of plasma membrane were changed in connection with the change of nutrient levels and temperatures during the leaves senescence of Officinal magnolia. And positive correlations between SOD activity and productive elasticity of chlorophyll, SOD activity and protein were statistically significant, and the effects of SOD on them were in increase stage. And the correlation between SOD activity and productive elasticity of permeability of plasma membrane was negative significantly, on which the effect of SOD activity was in negative stage.
