【Abstract】 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.更多还原
