| In order to know the effect of exogenous Se on wheat yield and quality,different wheat varieties foliar spraying of Se nutrients at flowering stage,the effects on grain yield,grain Se content and grain quality were studied.The results showed that yield of different wheat varieties increased after foliar spraying of Se nutrients.The yield of Zhongmai 895,Dengfeng 168 and Xiaoyan 22 respectively increased by 5.9%,2.9% and 4.6% compared to control.The content of organic Se and total Se increased significantly.The content of organic Se of Zhongmai895,Dengfeng168 and Xiaoyan22 increased by 537.3%,622.6% and 5323.2% compared to control and the content of total Se increased by 524.4%,767.8% and 5 306.4%,respectively.Foliar spraying of Se had no influence on grain bulk density,protein content,wet gluten content,water absorption and maximum resistance of wheat.But foliar spraying of Se had an impact on grain hardness,sedimentation value,stability time,extension area and ductility,and some differences in different varieties. |
