Object:In present thesis, the tolerances of27cultivars of wheat to sulfonamide were determined, and the effects of herbicide on acetolactate synthase were examined in those wheat.
Results:
(1)High concentrations of sulfonamide (≥22.5a.i.g/hm2) repressed the height, weight and numbers of fibrous root in27cultivars of wheat.Zhongyou9507,Shidong8,Shimail5and Jimai22have the highest tolerance to sulfonamide, whereas Kendong00(2),Xindong27, Xindong20, Gaocheng8901,Yannongl9,Xindong38and Xindong17have the...
