中文摘要 | 本研究探討外加藥劑是否能提高水稻對巴拉刈(paraquat)的抗性,試驗分別外加抗壞血酸(ascorbic acid)及多胺(polyamines)於感性水稻突變體分蘗期葉片,發現其中多胺較能有效提高水稻對巴拉刈之抗性,其中又以5 mM精胺(spermine, Spm)較10 mM有效。外加Spm雖然僅略提高ascorbate peroxidase活性,但H2O2顯著下降,故推測外加Spm可能誘導感性水稻突變體之抗氧化系統活性,降低巴拉刈對水稻造成的氧化傷害,以提高感性水稻對巴拉刈之抗性。 |
英文摘要 | Ascorbic acid and polyamines were tested on a paraquat-susceptible rice mutant to evaluate the effect of exogenously applied chemicals on its susceptibility to this herbicide. The results showed that polyamines, especially spermine at 5 mM, could improve rice tolerance to paraquat. Although the ascorbate peroxidase activity was only slightly increased by spermine, a significant decrease of H2O2 suggested that this polyamine effectively improved paraquat resistance of rice plant through enhanced activity of antioxidative system. |
