摘要
采用作物主根长法测定了常用两种磺酰脲类除草剂对玉米（Ｚｅａ ｍａｙｓ Ｌ．）农大１ ２３６和豌豆（Ｐｉｓｕｍ ｓａｔｉｖｕｍ Ｌ．）中碗６号的相对毒力，玉米试验结果表明，以ＩＣ ５０值比较，氯磺隆、胺苯磺隆对玉米的毒力较高，容易造成药害。豌豆试验结果表明，豌豆对氯磺隆和胺苯 磺隆比玉米更敏感。离体玉米和豌豆ＡＬＳ酶的研究表明，豌豆的ＡＬＳ对两种磺酰脲类除草剂较 玉米更敏感，氯磺隆对两种作物的ＡＬＳ抑制作用也较胺苯磺隆强。
The relative toxicity of two commonly used sulfonylurea herbici des were tested by main root length using maize CAU1236 (Zea mays L. ) and pea (Pisum sativum L.)No.6CB. IC50 values for maize indi cated that, chlorsulfuron, ethametsulfuron-methyl had high toxicity to maize, m aize had photo toxicity to these herbicide easily. Study on pea indicated that, pea was more sensitive to chlorsulfuron and ethametsulfuron-methyl. Study on in vitro ALS of maize and pea indicated that, ALS from pea was more sensitive than ALS from maize, chlorsulfuron had stronger inhibition to ALS of two crops than ethametsulfuron-methyl did．
