Study on physiology of drought resistance of Atriplex canescens.

【Objective and Method】The objectives of this study were to reveal the ten plants′ content of proline,TTC,MDA,soluble sugar,soluble protein,SOD,POD before and after stress treatments and were to compare their changes and analyze the physiological indexes of Atriplex canescens and other drought-resistant plants quatitatively and qualitatively.【Result】The results showed the content of proline of Atriplex canescens was the highest compared with that of other 9 kinds of plants.The plant in content of MDA was the lowest before and after stress treatments.The content of soluble sugar and soluble protein was in second before and after stress treatment.【Conclusion】It can clearly be seen,Atriplex canescens had the strongest drought-resistance compared with that of other plants.
