| 中文摘要: |
| 为明确我国玉米田杂草对烟嘧磺隆的抗性水平及分布现状, 于2010—2011年自山东、吉林、四川、河北4省采集连续多年施用烟嘧磺隆的玉米田杂草种子样本121个, 在温室内采用盆栽法测定了其对烟嘧磺隆的抗性。结果显示: 4个杂草样本对烟嘧磺隆产生了抗性, 其中山东淄博张店区傅家镇高家村的牛筋草抗性种群的GR50为25.76 g/hm2, 是敏感种群(1.33 g/hm2) 的19.37倍, 已产生明显的抗药性; 四川彭山县谢家镇岳油村的稗草、河北大城县广安镇夏屯村的虎尾草和河北邯郸的狗尾草分别产生了6.14、5.43和5.65倍的低水平抗性; 其余杂草样本均无明显抗性。同一杂草不同采集地点的敏感样本对烟嘧磺隆的敏感性存在差异。 |

| To investigate the resistance level and distribution of weed species to nicosulfuron in corn fields in China, a total of 121 populations of weed in nicosulfuron continuously used fields were collected from Shandong, Jilin, Sichuan and Hebei provinces from 2010 to 2011. The resistance was detected in the greenhouse by whole plant pot method. The results showed that four populations of weeds were resistant to nicosulfuron. Among them, the GR50 value of a resistant Eleusine indica population collected from Gaojia village, Fujia Town, Zhangdian District, Zibo, Shandong Province was 25.76 g/hm2, which was 19.37-fold higher than the corresponding susceptible population (GR50=1.33 g/hm2). The Echinochloa crusgalli from Pengshan, Sichuan Province, Chloris virgata from Dacheng, and Setaria viridis from Handan, Hebei Province showed low level resistance to nicosulfuron with resistance ratios of 6.14, 5.43 and 5.65, respectively. The rest samples were all susceptible to the nicosulfuron. |
