Abstract
The appearance quality, chemical components and smoking quality of Yunyan 97 at different altitudes were analyzed. [Method] Yunyan 97, a main cultivation variety in Qiaojia area, was the tested variety. Six altitudes were 1 450, 1 540, 1 600, 1 700, 1 830, 1 910, 2 020 m resp. , marked as treatment A, B, C, D, E, F, G. [Result] The results showed that the appearance quality and smoking quality increased firstly and descended secondly as the altitude increasing in the altitude range from 1 450 m to 2 020 m. The total sugar and reduced sugar content increased gradually as the altitude from 1 600 m to 1 830 m. The nicotine, total nitrogen and protein content decreased as the altitude rising of the altitude below 1 830 m. The smoking quality increased firstly and then descended as the altitude rising, and the smoking quality was best in the altitude of 1 700 m. [ Conclusion] The every indicator has better quality performance of the altitude 1 600 m to 1 830 m of flue-cured tobacco Yunyan 97.关键词
