Research on the Relationships between Chemical Components of Flue-cured Tobacco and Smoking Quality as well as Appearance Quality in Tobacco Area of Guizhou Province

WANG Jian-lin(Chuanyu Chinese Tobacco Industrial Corporation,Chengdu,Sichuan 610066)  
73 samples of flue-cured tobacco leaves were collected from main tobacco growing area of Guizhou Province in 2008,and relationships between chemical components of flue-cured tobacco and smoking quality as well as appearance quality were studied.Results showed that the chemical components of flue-cured tobacco leaf in Guizhou were suitable.The correlations between smoking indices and contents of chemical components such as nicotine,total nitrogen,total sugar,reducing sugar,potassium and starch were significant,but the correlation between the content of chlorine and smoking indices wasn' t significant.The correlations between appearance indices and contents of chemical components such as total nitrogen,total sugar,reducing sugar,potassium and starch were significant,but correlations between the appearance indices and the contents of nicotine and chlorine weren' t significant.
