| Abstract: |
| The experiment was carried out to study the effects of silicon on antioxidant enzymes(SOD, POD, and CAT) and osmolytes content of licorice leaves under NaCl stress by pot experiment. The results showed that the concentration of 0.2 g·kg-1 silicon had the strongest effect increasing the activities of SOD, POD, and CAT, by 37.44%, 26.98%, and 35.16% compared with the control, respectively. For the concentration of 0.6 g·kg-1, MDA was decreased by 35.63%, proline content by 38.15%, while the relative membrane permeability was increased by 17.69%, and the soluble protein content by 36.62%. In conclusion, silicon treatment could alleviate the damage degree of NaCl stress by promoting the antioxidant enzymes activities in licorice leaves. |
