三唑类物质对小麦灌浆期生理特性及产量性状的影响

Effect of spraying triazole matter on wheat physiological specific property and yield properties during seedfilling stage

在大田条件下研究了４ 种三唑类物质（ＴＨＲ，ＰＰ３３３，Ｓ－ ３３０７，Ｓ－３３０８）对小麦灌浆期生理特性及产量性状的影响。结果表明，三唑类物质能使叶片叶绿素含量提高，功能叶片光合强度加强，减缓旗叶ＮＲ 活性和ＳＯＤ 活性的下降速度，比叶重和粒叶比增加，子粒灌浆速度加快，粒重和产量提高－

The effect on Wheat physiological specific property and yield properties was studied of spraying four triazole matter(THR,PP 333 ,S-3307,S 3308)during seedfilling stage under natural conditions.The results shows that spraying triazole matter can raise chlorophyll content of leaves,strengthen photosynthesis intensity of functional leaves,retard dropping speed of NR and SOD activity of flag leaf,increase leaf weight per unit area and grain leaf area fatio,quicken seedfilling speed,raise 1000 seed weight and yield.
