Abstract
During 2008-2009,a field experiment was employed to study the contents of neutral aroma components in flue-cured tobacco leaf under plant density and apical regulator using the tobacco cultivar Jiyan No.9(local cultivars) in the Dunhua flue-cured tobacco producing area.Results showed that: both of the treatments,namely planting density and apical regulator,and their interactions extremely significantly affected five categories(the contents of products degraded by carotene,the contents of products degraded by cembranes,the contents of products of browing reaction,the contents of phenylalanine,the contents of other categories of neutral aroma components)of the contents of neutral aroma components;Effect of apical regulator is greater than plant density;With the planting density decreasing,the contents of different categories of neutral aroma components showed the tendency of decreased first and ascend later.The influence of apical regulator B2 on the contents of neutral aroma components in flue-cured tobacco leaf was stronger than B1 and B3;The present thesis concludes that structure of planting density A1(16 500 trees/ha) and apical regulator B2 on the quality of flue-cured tobacco leaf was reasonable,and the contents of neutral aroma components is biggest.
