Abstract
In order to investigate the physiological regulation measures on tobacco quality,effects of topping and smearing three exogenous hormones,IAA,KT and NAA,after topping on the contents of the potassium and nicotine in flue-cured tobacco have been studied by the field experiment in Zhengning County,Qingyang City,Gansu Province in 2007.The results showed that potassium content in tobacco leaves decreased significantly by 7.8 %~20.1 % after topping,especially in upper leaves,while nicotine content increased significantly by 33.5 %~34.3 %.Swearring three exogenous hormones after topping could significantly increase potassium content and decrease nicotine content,and improve flue-cured tobacco quality.The content of potassium increased most under the treatment of smearing with KT,which increased 57.42 %,26.62% and 40.26 % in upper,middle and lower leaves respectively.Meanwhile the content of nicotine decreased most under KT treatment,then NAA treatment,and decreased lest under IAA treatment.The quality of flue-cured tobacco was best when swearring KT after topping.
