Abstract: The effect of maturity on physical properties,chemical components and content of neutral aroma constituents in flue-cured tobacco leaves were studied.The results showed the optimun filling value,thickness of leaves,dragging force and tensile strength came from the middle leaves with proper maturity or yet-maturity,and the upper leaves with proper maturity or overmaturity.In the middle leaves with proper maturity or yet-maturity,the sugar content was high,and the contents of total N and nicotine were feasible.The inner quality of upper leaves with proper maturity or over-maturity was good,chemical components being harmonious.The contents of many neutral aroma constituents reached to their climax in middle leaves when proper maturated,and then declined,while they kept incease in upper leaves,and reached to their climax till over-maturated.

Key words: Flue-cured tobacco, Maturity, Physical properties, Chemical components, Neutral aroma constituents
