Abstract

Although regarded as one of the major cations contributing to soil salinity,sodium was also reported to be beneficial to plant growth.To elucidate the function of sodium in plants under salt stress,seedlings of Sesuvium portulacastrum were treated with NaCl at different concentrations（0,300,600,900 mmol.L^-1） to observe the leaf morphology,biomass weight and Na⁺ and K⁺ content.The results showed that the seedlings treated with 300 mmol.L^-1 NaCl produced the highest biomass.The flame emission and X-Ray microanalysis showed that large amounts of sodium ions were accumulated in the leaves,and that the leaf Na⁺ content was increased dramatically with the NaCl concentration while the leaf K⁺ content decreased,which leads to a high Na⁺ /K⁺ ratio.This study suggests that sodium of a given range of concentration could improve plant growth but high levels of sodium reduce uptake of K⁺ by the plant,hence leading to toxicity to the plant growth.
