摘要
在大豆开花期喷施 50mg/L的烯效唑后 ,叶片叶绿素、可溶性糖、可溶性蛋白质含量和POD、CAT的活性及光合速率都有明显提高。株高、结荚高度、秕荚率下降 ,上四节长度缩短 ,叶柄变短增粗 ,有效分枝数、主茎节数、单株荚数、单株粒数、百粒重及产量均有不同程度增加。
After S 3307 were sprayed upon the soybean during the flowering period,the activities of POD and CAT as well as the rate of photosynthesis all rised obviously.The plant height,the bearing pods height and the rate of unfilled pods decreased.The length of upper four inter nodes became short and the petiole also shortened and thickened.The number of pod setting branches,the number of main stems,the number of pods and grains of single plant,the weight of 100 grain and the yield of plots all increased to different degree.
