摘　　要：以湖南郴州烟区主栽烤烟品种云烟87为材料,测定了3个等级(B2F、C3F和X2F),共计18个样品的评吸质量得分和外观质量因素得分,采用相关分析和逐步回归分析等方法,分析了评吸得分和外观质量因素的相互关系。结果表明:①评吸质量与烟叶外观质量因素指标的颜色、成熟度、身份、油份都达到极显著相关关系,与色度达到显著相关关系,与叶片结构没有达到显著相关水平。②通过逐步回归分析湖南郴州烤烟评吸质量得分和外观质量因素所建立起来的回归方程∧Y=1.778+0.177X油份+0.206X成熟度+0.222X颜色可以表明评吸质量与油份、成熟度和颜色呈现正相关水平,这三个因素对评吸质量的相关影响达到95%的程度。The relationship of smoking quality and appearance quality indexes of 18 samples of Yunnan tobacco 87 was analyzed by correlation analysis and regression analysis.The results showed that smoking quality and appearance quality indexes,including in colour,maturity,degree and oil had highly significant correlation,and chroma had significant correlation,and leaf structure had no significant correlation.The regression equation of smoking quality and appearance quality index of Hunan tobacco Y∧=1.778＋0.177Xoil ＋0.206Xmajority ＋0.222Xcolor was established.The regression equation results showed the smoking quality and oil,maturity,colour had positive correlation and the effect of three factors on smoking quality reached 95 %.
