  • The relationships between the appearance quality and chemical composition index in flue-cured tobacco leaves in Baoshan tobacco-growing areas were studied.The results indicated that:1)descriptive statistics results showed that the flue-cured tobacco appearance quality in Baoshan area indicators,on average belong to the upper level,nicotine,total nitrogen was in the appropriate scope,total sugar,reducing sugar,protein and potassium content were higher and the chlorine content was low.2) simple correlation showed that tobacco appearance quality index had significant correlation with chemical composition.3)canonical correlation analysis results showed that the Canonical variable significant difference at 1% level (λ1=0.882 6**),group Ⅰ (u1,v1) typical variables,a linear combination of reflect in a certain range,with the increase of nicotine,total nitrogen and alkaline nitrogen ratio,sugar alkali than the decrease of the value,the appearance quality of the tobacco leaf color and oil content has a tendency to increase;Canonical variable significant difference at 1% level (λ2=0.760 7**),the first Ⅱ for typical variable (u2,v2),suggests that within a certain range,with the chemical composition of potassium,total sugar and the rise and fall of chlorine,tobacco maturity with the same change trend.4)grey correlation analysis showed that the smoke and baoshan district tobacco appearance quality correlation was the largest chemical composition of protein,total nitrogen,total sugar and reducing sugar,etc.
