| 中文摘要: |
| 为了明确山东省小麦田荠菜对苯磺隆的抗性水平及分布现状, 在温室中采用整株剂量-反应测定法测定了51份荠菜样本对苯磺隆的敏感性。结果表明, 山东省小麦田荠菜已普遍对苯磺隆产生抗性, 所测样本中, 抗性种群29个, 占总样本数的56.86%, 其中, 中、高抗种群27个, 占总样本数的52.94%。鲁南山区和鲁西北平原区采集点的荠菜对苯磺隆的抗性水平较高, 胶潍河谷平原区的荠菜对苯磺隆的抗性水平则相对较低。 |
| 英文摘要: |
| In order to detect the resistant level and distribution of shepherd’s purse to tribenuron-methyl in Shandong Province, whole-plant dose response experiments were conducted to determine the dose-response of 51 populations to tribenuron-methyl in greenhouse. The results showed that the resistant weed infestation in Shandong Province had become a serious problem. Among all the 51 samples, 29 populations were resistant, accounting for 56.86% and including 27 high and middle resistance biotypes. The resistant levels were much higher in mountain regions in southern Shandong and plain regions in northwestern Shandong, while the level in plain regions in eastern Shandong was much lower. |
