| 摘 要： | 通过测定天然芸苔素内酯对水稻幼苗谷胱甘肽(GSH)含量、谷胱甘肽-S-转移酶(GST)活性以及在离体和活体条件下对水稻幼苗乙酰乳酸合成酶(ALS)活力的影响,研究天然芸苔素内酯减轻胺苯磺隆对水稻药害的作用机理。结果表明,其作用机理与水稻幼苗GSH含量、GST活性变化没有太大相关性,可能与其能间接激活水稻幼苗ALS活力有较大相关。

| Abstract: | The mechanism of brassinolide reducing the phytotoxicity of ethametsulfuron to rice was studied through the experiments on the influence of brassinolide to rice glutathione (GSH) content, glutathione S transferase (GST) activity and acetolactate synthase (ALS) activity in vitro and in vivo . The results showed that it was not directly related to the GSH content and GST activity of rice but indirectly acted on the target enzyme of ALS. |
