Abstract
In the present study,the response of physiological parameters and stable carbon isotopic composition in Jatropha curcas L.and Vernicia fordii H.to osmotic stress was investigated and analyzed.Jatropha curcas had a better osmotic stress resistant ability than Vernicia fordii.As osmotic stress increased,Jatropha curcas had a lower decrease in leaf relative water content and chlorophyll content,higher increase in proline content and soluble sugar content,besides,it had a lower increase in relative electric conductivity;As osmotic stress increased,δ13C values of the two plants increased significantly,but under the same osmotic stress level,δ13C in Jatropha curcus was higher than Vernicia fordii,indicated that Jatropha curcus had a higher water use efficiency,and could grow better under drought stress conditions.It implied that δ13C value of leaves could reflect the drought tolerance of plants under certain conditions.
