A review on salinity adaptation mechanism and characteristics of Populus euphratica, a boon for arid ecosystems

Salinity is a worldwide problem, occurring in all climatic regions. Populus euphratica is a diverse riparian species, which survives in saline environments, and have numerous adaptation capacities to combat salinity stress. In this review, we collected available research information about the effect of salinity on its physiology, morphology, anatomy with relation to hydraulic traits. The information showed that P. euphratica can progressively tolerate high salinity stress by changing its stomatal aperture, activities of antioxidant, xylem anatomy and hydraulic conductivity. It can be a good option for afforestation and reclamation of salinized lands, which may be an option for increasing the production of feed stocks for non-food goods, and positive impact on climate.
