Title: Effect of Drought Stress and Rewatering on Physiological Characteristics of Delphinium grandiflorum Seedling
Abstract:Taking Delphinium grandiflorum seedlings as test materials,effect of soil drought stress and rewatering on membrane lipid peroxidation,protective enzyme activity and the permeable material of seedling...Taking Delphinium grandiflorum seedlings as test materials,effect of soil drought stress and rewatering on membrane lipid peroxidation,protective enzyme activity and the permeable material of seedlings were studied.The results showed that with the prolonging of drought stress time,cell membrane permeability and malondialdehyde rose significantly,in section 20 days of drought stress,the cell membrane permeability and malondialdehyde content reached the maximum,the plant was severely damaged.Proline content in leaves increased rapidly,after rewatering began to decline,but the content of soluble protein in the opposite.With the passage of time,the peroxidase and superoxide dismutase activity showed a downward trend after the first rise.After rewatering,peroxidase and superoxide dismutase activity showed a slowly increasing trend.In section 10 days of drought stress,the peroxidase and superoxide dismutase activity reached the maximum,the results showed that the plant had a higher ability of scavenging active oxygen.Read More
