Abstract


Soil salinization has become one of the most serious environmental problems in the world, which seriously affects the yield and quality of agricultural products. The physiological indexes of agricultural products grown in saline-alkali soil could show the ability of resisting saline-alkali. Therefore, the relationship between some important physiological indexes (photosynthesis, chlorophyll, osmotic regulation substances, phytohormones, antioxidant enzyme system, membrane permeability etc.) and salt tolerance of agricultural products was analyzed comprehensively. There are many kinds of physiological indexes, but a single physiological index could not be used to evaluate its salt tolerance.
