[Objective] The aim was to compare stem ratio and anatomical structure of leaves in different types of tobacco.[Method] Stem ratio and anatomical structure of leaves in different types of tobacco like flue-cured tobacco,sun-cured tobacco and burley tobacco were determined.[Result] Burley tobacco had the highest stem ratio of both fresh weight and dry weight;sun-cured tobacco took the second place;and flue-cured tobacco came next;but there was difference in the stem ratios of both fresh weight and dry weight among different parts of the same tobacco.Lower leaves in the 3 kinds of tobacco all had the largest leaf thickness,among them sun-cured tobacco was largest.Tobacco types had effects on leaf thickness and tissue structure.Both leaf thickness and tissue structure were in order of flue-cured tobacco sun-cured tobacco burley tobacco.[Conclusion] The research provides theoratical basis for high quality cultivation and industrial processing of different types of tobacco.
