Abstract

Six upper leaves in individual plants of tobacco variety Yunyan 97 were harvested and modulated at the same time in the study,and the following results were revealed.After continuous irrigation,the upper leaves opened more with the increasing maturity;the looseness of tissue structure was improved;leaves density decreased significantly;total sugar,reduced sugar,starch,total N and nicotine content were lower than that in normally irrigated tobacco leaves;K content was increased by 0.115%;nicotine content was decreased by 0.104%;internal quality became harmonious;yield,output value and the high class leaf proportion were all increased;economic characters were upgraded.
