| 摘 要： | 开花期玉米植株经ＭＯＣ抗旱剂叶面喷施处理后，在干旱条件下减缓了叶水势，叶片ＳＯＤ活性的下降幅度及ＭＤＡ和膜透性的增加幅度，在一定程度上阻止了干旱胁迫下活性氧对膜组分中不饱和脂肪酸，尤其是亚麻酸的氧化，从而保护了生物膜系统少受伤害，保证了玉米叶片光合作用的正常进行，增强了玉米的耐旱性。 |

| Abstract: | MOC droughtresistant chemicals sprayed on leaf surface of maize at anthesis under drought stress decreased the declined degree of leaf water potential, SOD activity, MDA and relative conductivity, retarded the peroxidation of unsaturated fatty acid on membrane caused by active oxygen, especially linoleic acid, and so protected the biomembrane systems and photosynthese of maize leaves, increased droughtresistance of maize, |
| Keywords: | maize drought stress MOC droughtresistant chemical membrane lipid peroxidation |
