Abstract: The effects of plant growth regulator on wheat had widely reported,but most of the studies focused on the yield and its component. There were less studies on wheat quality,so we designed this experiment. In the field conditions we designed two factors studied nitrogen and chemical. The results showed that chemical control and nitrogen treatment was propitious to adjust the protein components and the processing quality. The study showed that compared with 180 kg /ha,270 kg /ha significantly increased albumin,dry and wet gluten content and flour water absorption,but it was unconductive to the improvement of the globulin and gliadin content,with more nitrogen applied;Compared with the contrast,there were positive effects toward to the protein components and processing quality spraying wheat growth regulator Maijujin at setting stage,in which the effects on albumin,wet and dry gluten content and water absorption were significant. Spraying ethephon water agent could improve rheology. There were some positive effects on the sedimentation value and water absorption of spraying poly-AA sylvite at setting stage.
