Abstract
The experiment investigated the effects of exogenous calcium on some physiological characteristics of Jatropha curcas under drought stress after soaking Jatropha curcas seeds with CaCl2 solution of 0.01,0.05,0.1 mol/ L concentration and spraying leaves with Ca(NO3)2 solution of 0.01 mol/L concentration.Interrelated physiological indexes was mensurated including the germination rate,relative water content,proline(Pro) content and malondialdehyde(MDA) content of leaves.Results showed that soaking seeds with CaCl2 solution can increase the relative water content and Pro content,decrease the MDA content;low concentration of CaCl2(≤0.05 mol/L)can promote the germination trend and rate of seeds.Spraying leaves with Ca(NO3)2 increased the relative water content and Pro content,decreased the MDA content under the stress of PEG.These results indicated that exogenous calcium may improve the drought resistant capacity,enhance infiltration regulation and protecte the structure of plasma membrane,regulate the related physiological responses induced by drought stress.
