Abstract: Seedlings of Agropyron cristatum were stressed with Na2CO3 and NaHCO3 (0, 30, 60, 90, 120, or 150 mmol/L) in the greenhouse. Eight indices (biomass, root-shoot ratio, malondialdehyde (MDA) content, chlorophyl content, soluble sugar content, proline content, SOD activity and POD activity) were determined. As the stress increased in treatments, the content of MDA and soluble sugar also increased whereas the biomass, root-shoot ratio, and chlorophyl content increased initially and then decreased. The results showed that low concentrations of alkaline stress on A. cristatum had some role in promoting growth. Proline accumulated before soluble sugar and Na2CO3 stress was greater than NaHCO3 stress.
