Abstract：In order to reveal the surface color regional disparity of C3F grade tobacco leaves,using the C3F grade cured tobacco leaves from 14 provinces in 2015 as the experimental materials,the surface color of tobacco leaf samples were quantitatively analyzed by the methods of multiple comparison and system clustering.The results were as follows.The surface color spatial distribution features of the flue-cured tobacco showed that the brightness (L*) was 47.90~63.77, the red degrees (a*) was 14.12~15.56, the yellow degree (b*) was 39.91~53.52, and the color saturation (C*) was 42.07~55.73.There were strong regional differences in C3F grade flue-cured tobacco leaf surface color.The b* and C* of upper-middle reaches of Yangtze river and Southwest tobacco areas were significantly higher than that of Southeast tobacco areas.There were no significant differences in C3F grade tobacco leaf surface color feature parameters in Huanghuai and North tobacco areas.The ecological condition was the important reason for formation of C3F grade flue-cured tobacco leaf surface color regional differences, and variety had the small effects.
