Abstract Reaumuria soongorica, an extreme xeric subshrubs in desert areas, was used to quantified the water status, chlorophyll contents, antioxidant enzymes activities and osmotic adjustment solute contents in three habitats(piedmont of desert, piedmont of Gobi and the middle reaches of the Gobi), and to investigate the adaptive mechanism of physiological and biochemical response to desert condition. The results showed that in different habitats, the relative water content and leaf water potential of R.soongorica decreased with the soil moisture content decreasing, while the chlorophyll contents rose. Meanwhile, with the soil drought intensified, superoxide dismutase (SOD) and peroxidase (POD) activities increased. In gobi desert with lesser soil moisture content, the osmotic adjustment substances were increasing. It could be concluded that the in different habitats, increasing SOD and POD activities of R.soongorica was one of the major antioxidant protection mechanism to resist drought environments. Osmotic adjustment played an important role in water shortage conditions to maintain a lower osmotic potential, and is more conducive to plant water uptake and enhancing its drought tolerance.
