摘要: :概述了盐胁迫下外源钙对植物耐盐性的影响,钙可抑制活性氧物质的生成、保护细胞质膜的结构、维持正常的光合作用,从而提高植物的耐盐性。而且细胞内的钙离子作为第二信使传递胁迫信号,调节植物体内的生理生化反应。

Abstract: The effects of exogenous calcium on plant under salt stress are reviewed in this article.calcium could improve the salt-tolerance capability ,inhabit the production of active oxygen substances,protect the structure of cell plasma membrane and maintain normal photosythesis. The internal cellular Ca2+, moreover, act as a second messenger to transduct the salt-stress signal ,and regulate the physiological and biochemical responses in plant.
