摘要
通过盆栽试验,探讨了丁草胺对不同秧苗素质水稻生理生化指标的影响。丁草胺处理后叶片的光合作用速率、叶绿素含量和根系活力下降,而GSH含量和SOD活性上升。水稻弱苗对丁草胺的敏感性高于壮苗。
The experiment goes along with potted rice, inquirying into the effect of butachlor on physiological and biochemical characteristics of rice was analyzed by pot cultivation. The trial result indicated that the photosynthetic rate,total carbohydrate content and activity of the root were decreased, the GSH conten and the activity of SOD were increased after butachlor treatment. Sensitivity of the week seedling to butachlor is higher than the sound one.
