Cluster Evaluation and Analysis on Chemical Components of Flue-cured Tobacco K326 in Yunnan

The main chemical components of X2F,C3F,B2F leaves of flue-cured tobacco K326 from 19 tobacco regions of Yunnan province were analyzed and comprehensively evaluated.The result indicated that the average chemical components of flue-cured tobacco samples in Yunnan were almost in normal range of high quality flue-cured tobacco,which indicated that the flue-cured tobacco in Yunnan had appropriate content of chemical components,and had high quality.By systematically clustering on C3F,the tobacco regions of Yunnan were divided into four sub-regions of high chlorin-low potassium areas,high potassium-low nicotine areas,high sugarlow chlorin areas,and high nicotine-low sugar areas.The quality of tobacco leaves of the second and third sub-regions performed better,which included Xinpin county,Gengma county,Malong county,Jingdong county and Lufeng county.
