| 摘 要： | 以湖南湘西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湘西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=3.187+0.271X油份+0.157X成熟度可以表明评吸质量与油份和成熟度呈现正相关水平,这两个因素对评吸质量的相关影响达到92.1%的程度。

| Abstract: | Analyzed the relationship between smoking quality and appearance quality index by correlation analysis and regression analysis,through three degrade（B2F,C3F and X2F）.The breed is Yunnan tobacco 87,which is the majority plant breed of Xiang-Xi tobacco-growing area.The result showed that：（1）The appearance quality of color,majority,degree and oil reached extremely significant difference level with smoking quality,and chroma reached significant difference level,leaf structure had no significant difference（2） The regression equation of smoking quality and appearance quality index of Hunan tobacco Y=3.187＋0.271Xoil ＋0.157Xmaturity which indicated smoking quality had correlation with oil and majority.The two characters had 92.1% influence on smoking quality. |
