How to enhance plant salt tolerance has always been focus issue up to present.It has been reported that phosphorus application can increase plant tolerance to osmotic stress by elevating anti-dehydration of protoplast.Intracellular ion homeostasis is a fundamental process for keeping physiological activity of living cells and ion flux regulation is necessary for plant cells to exclude toxic ions and to accumulate essential ions to a proper level.The effects of exogenous phosphorus on ionic homeostasis of pl...
