中文摘要:为明确山东省冬小麦田播娘蒿对苯磺隆的抗性水平及分布现状，在温室中采用整株剂量-反应测定法测定了山东省各小麦主产区的37份播娘蒿对苯磺隆的敏感性。结果显示，山东省播娘蒿对苯磺隆的抗药性已非常普遍，所测样品中，抗性生物型有29个，占总采样数的78.38%，敏感生物型仅8个，占21.62%。抗性生物型中，中抗性生物型最多占51.72%，低抗性生物型占31.03%，高抗性生物型占17.24%。鲁西南平洼区和鲁西北平原区播娘蒿抗性水平普遍较高，鲁南山区、胶潍河谷平原区和鲁北滨海区抗性水平相对较低。

Abstract:In order to examine the resistance level and distribution of flixweed to tribenuron-methyl in Shandong Province, 37 biotypes of the flixweed were collected from winter wheat fields. Whole-plant dose response experiments were conducted to determine the responses of different flixweed biotypes to tribenuron-methyl in glasshouses. The results showed that the resistant flixweed occurrence in Shandong Province has become a serious problem. From a total of 37 biotypes, 29 were resistant and 8 were susceptible, and the rate was 78.38% and 21.62%, respectively. There were 9 low-level, 15 mid-level and 5 high-level resistant biotypes, accounting for 31.03%, 51.72% and 17.24% of the resistant biotypes, respectively. The results showed that the resistance level of flixweed biotypes was high in the plain regions in southwestern and northwestern Shandong, and the levels in mountain regions in southern Shandong and coastal regions in northern Shandong were much lower.
