吡虫啉对小白菜生长及其生理生化指标的影响

摘要

本试验以四季小白菜为试材,研究不同剂量的吡虫啉溶液对小白菜生长及其生理生化指标的影响结果表明：吡虫啉处理对提高小白菜的生长及抗性具有明显的作用.在一定范围内,随着吡虫啉溶液稀释倍数的增加,脯氨酸、可溶性糖、叶绿素、根系活力升高,丙二醛、相对电导率降低,其中以5%吡虫啉稀释到600倍时效果最好.%The effects of imidacloprid on Chinese cabbage growth and physiological and biochemical index were studied.The results show that： imidacloprid improved obviously growth and resistance of Chinese cabbage.Within a certain range,when dilution of imidacloprid solution increased,proline,soluble sugars,chlorophyll content,and root activity of Chinese cabbage increased,but malondialdehyde and the relative conductivity reduced.Among them,the best results obtained when 5% imidacloprid diluted to 600 times.
