高盐对植物细胞伤害的一个重要方面是由于细胞质内的离子不平衡造成的,特别是细胞中高Na~+/K~+比例破坏了细胞正常的生理代谢,高盐条件下引起离子不平衡的可能原因是Na~+大量内流进入细胞,K~+吸收相对减少。植物细胞如果要在高盐的环境条件下存活,必须有维持正常胞内离子相对平衡(较高的K~+/Na~+)的能力。以往的研究表明:质膜和液泡膜上的主动转运系统,如:Na~+/K~+,Na~+/H~+反向转运载体和H~+泵在维持细胞质内高的K~+/ An important aspect of high salt damage to plant cells is due to ion imbalances in the cytoplasm, especially the high Na ~ + / K ~ + ratio in cells that disrupts the normal physiological metabolism of the cells and ion imbalances under high salt conditions The possible reason is that a large amount of Na ~ + influx into the cells, K ~ + absorption decreased. Plant cells must maintain the normal balance of intracellular ions (higher K ~ + / Na ~ +) if they are to survive in high salt environment. Previous studies have shown that the active transport systems on the plasma membrane and tonoplast such as Na ~ + / K ~ +, Na ~ + / H ~ + antiporter and H ~ + pump maintain the high K ~ + /
