摘　　要：研究了保山烟区烤烟外观质量与化学成分的关系,结果如下:1)描述性统计表明,保山烟区烤烟外观质量各项指标平均值得分属中等偏上水平,烟碱、总氮在适宜范围内,总糖、还原糖、蛋白质和钾含量较高,氯含量较低.2)相关分析表明,烤烟6项外观质量与若干化学成分含量具有显著或极显著相关关系.3)第Ⅰ对典型变量(u1,v1)(λ1=0.882 6**)反映出,在一定范围内,随着烟碱、总氮的升高和氮碱比、糖碱比数值的减小,烤烟外观质量指标如色度、油分有增加的趋势;第Ⅱ对典型变量(u2,v2)(λ2=0.760 7**)表明,在一定范围内,随着化学成分钾、总糖和氯的升降,烤烟外观质量成熟度具有相同的变化趋势.4)灰色关联分析表明,与保山烟区烤烟外观质量关联度较大的化学成分为蛋白质、总氮、总糖和还原糖等.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 aver- age belong to the upper level, nicotine, total nitrogen was in the appropriate scope, total sugar, reducing sug- ar, 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）ca- nonical correlation analysis results showed that the Canonical variable significant difference at 1% level （λi =0. 882 6＊ ＊ ） ,group [ （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 alkah than tlae Oecrease ox me value, the appearance quality of the tobacco leaf color and oil content has a tendency to increase ; Canoni- cal variable significant difference at 1% level （λ2 =0. 760 7＊＊＂ ） ,the first I~ 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.
