| 中文摘要: |
| 为明确河南省冬麦田3种阔叶杂草猪殃殃、播娘蒿、牛繁缕对苯磺隆的抗性水平和分布现状，在温室中采用整株剂量-反应测定法测定了3种杂草的40个种群对苯磺隆的敏感性。结果表明，河南省3种阔叶杂草已普遍对苯磺隆产生抗性，所测样本中，抗性种群27个，占总采样数的67.50%，其中牛繁缕抗性水平最高，猪殃殃居中，播娘蒿最低。豫中和豫南地区3种杂草的整体抗性水平较高，豫西和豫西南抗性水平相对较低。 |
| 英文摘要: |
| In order to examine the resistance level of Galium aparine,Galium aparine and Malachium aquaticum to tribenuron-methyl and their distribution in Henan province,whole-plant dosimetry experiment was conducted to determine the response of 40 populations to tribenuron-methyl in greenhouse. Results showed that the resistant weeds occurrence in Henan province has become a serious problem. There were 27 resistant populations with the rate of 67.50% in the total samples. The resistant level of Malachium aquaticum to tribenuron-methyl was the highest,followed by Galium aparine and Galium aparine. The resistant level of three kinds of broadleaved weeds was high in central and southern regions,and the levels in western and southwestern Henan province were much lower. |
