[Objective] The aim was to find the best α-NAA application method in flue-cured tobacco production. [Method]After topping,α-NAA was applied on different parts of tobacco to study its effects on agronomic traits,economic traits,chemical traits and sensory quality in mature period. [Result] Applying α-NAA can increase the leaf length and width of flue-cured tobacco,and it also can improve the yield,output value and the radio of secondary smoke. What is more,α-NAA can not only improve the content of chemical indexes like hydrolysis sugar and p...
