分析了抗根腐病突变系和抗赤霉病突变系的过氧化物酶和超氧化物歧化酶等同工酶及其活性的变化，测定了优质突变系的麦谷蛋白亚基组成，研究了毒素或病原菌作用下抗病突变系细胞超微结构和细胞表面糖蛋白层的变化。结果表明，在毒素作用下不仅抗病突变系过氧化物同工酶的谱带数、谱带强度发生了变化，而且总活性也明显提高；超氧化物歧化酶的活性也有不同程度的增加； 抗病突变系叶片细胞超微结构的破坏程度比亲本轻。在病原菌作用下，抗病突变系内颖细胞表面的糖蛋白层较亲本厚、消失速度较亲本慢。这些特征与它们的抗病性相一致。优质突变系具有特殊的低分子量麦谷蛋白亚基。
The changes of peroxidase and superoxide dismutase isoenzymes and their activities in root rot resistant mutants and blast head blight resistant mutants were analyzed. The glutenin subunit composition of high quality mutant lines was determined. The effects of toxins Or pathogen-resistant mutant cell lines ultrastructures and cell surface glycoprotein changes. The results showed that under the action of toxins, not only the number of bands and band intensities of peroxidase isozymes in disease-resistant mutant lines changed, but also the total activities were significantly increased; the activity of superoxide dismutase also increased to some extent; Disease resistance mutant leaves of the ultrastructure damage than the parental light. Under the action of pathogenic bacteria, the glycoprotein on the cell surface of the disease-resistant mutant lines is thicker than the parental ones, and its disappearance rate is slower than that of the parental lines. These features are consistent with their disease resistance. High quality mutants have a special low molecular weight glutenin subunit.
