The study on the mechanism of plant salt- tolerance has the important significance to improve and utilizes of saline soil, and to cultivate and breed new varieties of salt-tolerant plants. According to the published studies on plant salt-tolerance, plants show a range of physiological and ecological adaptation, including selectively absorbing inorganic ions, regulating K+/Na+ ratio to lower osmotic pressure in vivo; salt stress increases the antioxidant enzyme activity, slows down the damage of reactive oxygen species; hormone can induce some of the important gene expression in salt-tolerance signaling pathways; Some halophytes photosynthetic pathway changes could help improving their ability for adapting saline habitats; saline environment promotes that environment-related proteins are highly expressed in vivo for salt-tolerant plants; and some morphological changes in the structure of plants occur, through salt excretion, salt separation, and salt rejection, the plants adapt the salt environment. Thus, physiological ecology adaptation of plant salt-tolerant is regulated and controlled by many aspects.
