The results showed that with the normal dosage 60g/hm2, inhibiting rate of the plant height and weight of Taiyu 2, Jinzhenzhu, Taiyu 15, Zinuo and other three breeds are beyond 40% and 30%, and it is obvious that plant growing is inhibited, the leaves etiolate and new leaves twist severely and couldn't grow normally. Inhibiting rate of the plant height of Ziyu 2, Taiyu 2, Liaoyu 18, Ludan 50, Zhengdan 958 and some other varieties are between 30.6% and 38.1%, the sensitivity of these varieties are lower and the plant modalities are not influenced bigger; in addition, Nongda 108, Nongda 2008, Xinyu 958 and Taiyu 12 grow healthy, the resistance to nicosulfuron are higher compared with other varieties.

温室盆栽测定结果表明，在烟嘧磺隆大田常规用量60g ai/hm2下，各品种对药剂的敏感性差异显著，泰玉2号、金珍珠、泰玉15号、紫糯等7个品种对烟嘧磺隆表现较为敏感，株高抑制率均在40.4%以上，鲜重抑制率在31.37%以上，表现为植株生长受到抑制，叶片黄化，新叶牛尾状扭曲不能正常抽出；淄玉2号、泰玉2号、聊玉18、鲁单50、鲁原单14、郑单958等品种的株高抑制率在30.6%～38.1%，敏感性略低；而农大2008、农大108、鑫玉958和泰玉12号生长正常，耐药性相对较高，无明显药害症状。
