Abstract: In order to find out the relationship of appearance characters with its main chemical components and smoking quality of flue-cured tobacco, 96 samples of flue-cured tobacco were sampled from tobacco planting bases of Tobacco Guizhou Industrial Co. Ltd. Their appearance characters and smoking quality were evaluated and their main chemical components were determined. The relationship between appearance quality indexes of tobacco leaf samples and inner quality was studied, including the preliminarily quantified overall appearance quality status of tobacco leaf and the quantitative relationships between tobacco quality indexes. The results showed that the relationship of tobacco leaf quality indexes were different among different tobacco planting bases. Relationship between appearance quality indexes of tobacco leaf in Yanyuan, Yongan and Guizhou Province was apparent. And stalk position, color, oil and chrominance had closer correlation with other appearance indicators. The appearance structure of tobacco leaf in Guizhou Province showed significant correlation with other appearance indicators. However, the relationship between structure and other appearance indicators of tobacco leaf in Yanyuan and Yongan was not obvious.
