摘要
Abstract
The seeding of Linseed under Pb(Ac)2 stress in the concentrations of 0.1 mmol/L、 0.5 mmol/L and 1.0 mmol/L was studied through 96 h to determin the change of proline content, malondialdehyde content, the activity of superoxide dismutase, peroxidase and catalase in different treatment periods leaves of Linseed . The results indicated that the Nitric Oxide has thrown a light on the increasing of malondialdehyde content in Linseed seedling leaves compared with Pb(Ac)2 stress, the activities of antioxidant enzymes were increased, the content of praline were increase . The protective ability of concentrations of 0.1 mmol/L was significantly better than the concentrations of 1.0 mmol/L .关键词
