盐胁迫对植物的影响及植物耐盐机理研究进展

盐分是影响植物生长发育的一个重要环境因素，盐胁迫对植物的整个生命进程产生影响，盐分通过渗透胁迫、离子毒害，使植物细胞膜透性改变，造成氧化胁迫、代谢紊乱及蛋白质合成受阻等现象，植物的耐盐性主要体现在离子的选择性吸收和区域化作用、渗透调节、光合作用途径的改变以及活性氧清除机制。

Advances in Research on Effects of Salt Stress on Plant and The Mechanism of Plant Salt Tolerance

Salinity is one of the most important environmental factors affecting plant growth and development. Salt stress affects plant the whole life process. Salt makes the plant cell membrane permeability changes by osmotic stress, ion toxicity, cause oxidative stress, metabolism, protein synthesis of hindered and other phenomena. The mechanisms of salt resistance in plants were described from the ion selective absorption and regional effects, osmotic adjustment, changes of photosynthesis pathway and active oxygen scavenging mechanism.
