Abstract: Quinoa is a facultative halophytic plant species with high tolerant to salinity, and some varieties could tolerant salimity level as high as those present in sea water. A number of studies have been performed on the influence of salt stress on quinoa and the mechanism of salt tolerance in quinoa. This review summarized the existing knowledge of the salt tolerance of quinoa. The key traits included an efficient control of Na+ sequestration in leaf vacuoles, xylem Na+ loading, higher ROS tolerance, better K+ retention, and an efficient control over stomatal development and aperture. And the potential of quinoa for cultivation in salt-affected regions was discussed to provide the theoretically basis for quinoa being cultivated in other arid and semi-arid regions, phytoremediation of saline soils and further research in the field of plant salt tolerance.
