黄瓜是我国栽培面积最大的喜温蔬菜之一。在生产上,高温干旱等环境胁、迫因子严重危害黄瓜的产量和品质,甚至导致绝收。任安芝等综述了SOD与水分、盐分、低温和大气污染等逆境胁迫之间的关系,认为:各种逆境胁迫引起的活性氧代谢平衡失调、生物膜结构破坏是导致植物遭受逆境伤害的机理之一。通过基因工程提高植物体内抗氧化酶活性及增加抗氧化代谢的水平是增强植物抗逆性的有效
Cucumber is one of the most thermophilic vegetables in our country. In production, high temperature and drought and other environmental threats, forcing factors seriously endanger the yield and quality of cucumber, and even lead to absolute income. Ren Anzhi et al. Summarized the relationship between SOD and stresses such as water, salt, low temperature and air pollution. It is concluded that the imbalance of reactive oxygen species metabolism caused by various stress conditions and the destruction of biofilm structure are one of the mechanisms that lead to stress damage to plants . Through genetic engineering to enhance plant antioxidant enzyme activity and increase the level of antioxidant metabolism is to enhance plant stress resistance
