Abstract: To distinguish the appearances of flue-cured tobacco leaves via planting areas rapidly, the appearance characteristics and their relationships with intrinsic leaf quality of 24 C2F leaf samples of bouquet-sweetness flavor type were collected from 6 planting areas (Ankang and Shangluo in Shaanxi, Enshi and Yichang in Hubei, Xiangxi in Hunan, Qianjiang in Chongqing). The analysis results showed that: 1) The leaf appearances were characterized by white background color, moderate to thin thickness, weak wax texture, relatively soft(for several samples) leaf, slight leaf color difference between front and back, minor to moderate (for several samples) leaf body difference between the tip and base, bright and slightly vivid?luster, smooth to relatively smooth leaf surface texture, orange to?light orange shade of color; orange to slightly lemon color, mature tobacco leaves, relatively loose and partial loose leaf structure, moderate (several samples were slightly thin) body, oily, moderate to slightly?strong color intensity. 2) The appearance characteristics extremely significantly positively correlated to several routine chemical indexes of tobacco leaves, including the softer the leaf, the higher the chlorine content; the smoother the leaf tissue, the higher the starch content; the oilier the leaf, the higher the reducing sugar content. 3) There were relatively close relationships between appearance characteristics and sensory qualities. The slighter the leaf color difference between the front and back, the more obvious the bouquet-sweetness scent; the more significant the flavor type, the stronger the sense of suspension and the weaker the burnt-sweetness scent would be. In addition, the softer the leaf, the weaker the scorched odor, the smoother and milder the smoke would be; the looser the leaf structure, the more and milder the smoke would be; the oilier the leaf, the weaker the scorched odor would be. Therefore, the leaf color difference between the front and back was?the key appearance characteristic index affecting the style of tobacco leaves of bouquet-sweetness flavor type.
