| Abstract: |
| In this study, the effects of exogenous calcium and H2O2 on the activity of oxygen (O-2) themalondialdehyde content (MDA) , the activity of superoxide dismutase (SOD) , the activity of peroxide (POD) , catalase (CAT) and antiscorbutic acid peroxide enzyme (APX) were examined in Lycium barbarum L.chloroplast under NaCl stress.The results indicated that, under NaCl stress, O-2 production rate and MDA content generally increased, meanwhile CAT and POD activities were also higher than those of control.When adding exogenous Ca2＋ and H2O2 under NaCl stress, MDA content and O-2 production rate were slower than those of NaCl stress, while protecting enzyme APX, CAT and POD activities increased compared to NaCl stress.It indicated that exogenous Ca2＋ and H2O2 alleviated NaCl stress injury to plants to some extent. |
