摘　　要：采用温室盆栽法和培养皿法分别测定7省14个县市14块麦田的猪殃殃潜在抗药性生物型和临近非耕地敏感生物型对苯磺隆的抗性水平。温室盆栽法试验结果表明,除河北省石家庄、山西省太原、陕西省周至、山东省泰安采集点麦田猪殃殃生物型对苯磺隆仍处于敏感状态外,其它地区麦田猪殃殃均产生了不同程度的抗药性,抗性倍数在1.6～4.3之间,其中河南省许昌采集点抗药性最高,达4.3倍,安徽省太和、陕西省华县采集点抗药性最低,抗性倍数均为1.6;培养皿法试验结果表明,河南省许昌采集点抗药性较高,抗性倍数为2.2,而安徽省太和、陕西省华县采集点抗药性较低,抗性倍数分别为1.9和1.7。两种方法的抗性趋势基本一致。In order to evaluate the resistance of Galium aparine to tribenuron-methyl, 14 potential resistant biotypes were collected from winter wheat fields of 14 counties or cities in Shandong, Shanxi, Henan, Hebei, Jiangsu, Shaanxi, and Anhui Provinces, and 14 susceptible biotypes were correspondingly collected from the nearby non-farming lands never applied herbicides. Greenhouse pot tests and the quicktest in Petri dish were conducted to detect the resistance level. The results of greenhouse pot tests showed that except for the potential resistant biotypes from the collecting sites of Shijiazhuang, Hebei Province, Taiyuan, Shanxi Province, Zhouzhi, Shaanxi Province, and Tai＇ an, Shandong Province, all the other potential resistant biotypes evolved resistance to tribenuron-methyl, with a resistance factor ranging from 1.6 to 4.3, with the highest 4.3 in the collecting site of Xuchang, Henan Province and the lowest 1.6 in the collecting sites of Taihe, Anhui Province and Huaxian, Shaanxi Province. The resistance in the collecting site of Xuchang, Henan Province is relatively higher than those in the collecting sites of Taihe, Anhui Province and Huaxian, Shaanxi Province, with a resistance factor 2.2, 1.9, 1.7 respectively. The results of the quick-test in Petri dish are in accordance with those of greenhouse pot tests on the whole.
