Effect of Ampicillin Sodium on Physiology and Grain Yield of Wheat

In order to explore the effect of ampicillin sodium on the morphology,physiological change and grain yield of wheat,the leaves of Zhengzhou 9023 were sprayed with different concentrations of the ampicillin sodium solution(0,400,600,800,1 000 and 1 200 mg·L~(-1)) at three leaves stage.Chlorophyll contents,activity of nitrate reductase and tiller number before winter were measured in different period after spraying,and the grain yield was be investigated in harvest season.The results indicate that ampicillin sodium can increase the chlorophyll contents and activity of nitrate reductase in leaves and tiller number,the output was enhanced markedly.The effect of 800 mg·L~(-1) is the best.
