| Abstract: |
| Glycyrrhiza glabra seedlings were treated with the osmotic stress solution mannitol((-0.5)MPa,-1.0MPa).The content of MDA and two defense enzymes activities(POD,CAT) in Glycyrrhiza glabra seedlings roots were measured at the fifth day after treatment.The content of MDA increased at-0.5 MPa and-1.0 MPa mannitol stress,the increase rate was higher at-1.0 MPa stress than that at-0.5 MPa stress,POD activity increased at-0.5 MPa stress and declined at-1.0 MPa stress,CAT activities raised with the stress level.This result suggested that the two defense enzymes POD and CAT might play a key role in reducing lipid peroxidation under drought stress. |
