簡介：浙江大學博士學位論文酰胺類除草劑的生物化學行為以及手性選擇性行為研究姓名劉惠君申請學位級別博士專業(yè)環(huán)境科學指導教師劉維屏20050508⑧浙江大學博士學位論文甲草胺，而S對映體對大型蚤的慢性毒性作用小于RAC異丙甲草胺。大型蚤的生存期和胎數等參數的結果表明RAC一異丙甲草胺對大型蚤的慢性毒性是其S型的10倍；從產幼蚤數這個參數來看，RAC異丙甲草胺對大型蚤的毒性相當于S型毒性的100倍S型的NOEC為O1MG／L，RAG一的NOEC為0001MG／L。低濃度的S異丙甲草胺比RAC異丙甲草胺對環(huán)境生物大型蚤的毒性要低。環(huán)境因素腐殖酸、蒙脫石、PH和硬度影響了S異丙甲草胺對大型蚤的毒性。從水稻中提取的細胞色素P450與供試除草劑作用的VMAX為丁草胺丙草胺異丙甲草胺S異丙甲草胺，對丁草胺的降解速率遠大于對異丙甲草胺的降解速率，對異丙甲草胺的降解速率大于對S對映體的降解速率。除草劑濃度的增加，其降解速率下降，半衰期延長。水稻體內細胞色素P450對除草劑的代謝作用是水稻對供試酰胺類除草劑產生選擇性的一個重要原因。植物細胞色素P450對異丙甲草胺的代謝作用的差異可能是導致RAC異丙甲草胺和S異丙甲草胺對水稻等敏感植物的藥效差異的一個原因。關鍵詞酰胺類除草劑手性選擇性土壤酶活性土壤微生物量；相互作用機理；大型蚤毒性試驗；植物細胞色素P450；II
