摘　　要：在盐渍化土壤中,植物会受到盐胁迫的伤害。为缓解植物遭受盐胁迫伤害,合理有效地利用盐渍化土壤,分析并探讨了盐胁迫条件下外源NO对植物伤害的缓解效应。结果显示,在盐胁迫条件下,经过外源NO处理后可明显提高植物种子萌发和幼苗生长,并能促使光合机构免于伤害。进一步分析表明,外源NO对盐胁迫下植株的保护效应主要是通过改善内含物含量以及调控抗氧化酶系统而发挥作用。In salinized soil,plants can be harmed by salt stress.In order to alleviate the damage of plants under salt stress,for reasonable and effective use of salinized soil,this paper analyzed and discussed the mitigation effect of exogenous NO on plant injury under salt stress.The results showed that,under salt stress,the seed germination and seedling growth of plants could be significantly improved by exogenous NO treatment,and the contents of inclusion could be improved.Furthermore,exogenous NO could prevent the photosynthetic apparatus from harm.Further analysis indicated that the protective effect of NO on the plants under salt stress was mainly through the regulation of antioxidant enzyme system.
