| Abstract: |
| Maize(Shendan16 and T2208) seedlings were used to study on survival rate,electrolyte leakage(EL) of seedlings,content of MDA,activities of CAT,SOD and POD of maize seedlings in drought,chilling,heat and salt stress was induced.The results of cross adaptation showed that,the resistance to drought,chilling,heat and salt stress of maize seedlings was improved through short-term drought pretreatment,the resistance to stress and survival rate of maize were also improved,while EL and the content of MDA were reduced,and the activities of CAT,SOD and POD were improved.The phenomenon of cross adaptation on maize seedlings was demonstrated.These evidences showed that maize seedlings have the ability of cross-adaptation under drought induced. |
