Abstract
Effects of combined application of suckering agent and growth regulator on quality of flue-cured tobacco leaves were studied through pot,micro-plot,and plot experiments.Results showed that in plot experiment,potassium content of upper and lower leaves was increased significantly by applying suckering agent after decapitation before daubing growth regulator,while nicotine content of middle and lower leaves was decreased significantly.In pot experiment,potassium content of middle and lower leaves was increased significantly by application suckering agent after decapitation and then daubing growth regulator either immediately or one day or two days later,while nicotine content of upper,middle,and lower leaves were decreased significantly.The best effect was obtained in treatment of daubing growth regulator immediately or one day later.In micro-plot experiment,potassium content of tobacco leaves was increased and nicotine content was decreased significantly in all treatments of suckering agent application methods(showering or daubing),and daubing was better than showering.Potassium and nicotine content between tobacco varieties were different,but the change was very similar,and there were significant negative correlations between potassium and nicotine content.
