以湖南主产烟区烤烟样本为材料,通过对烟叶外观质量和评吸质量的量化评定以及对烟叶物理性状和化学成分的测定,应用典型相关分析方法分析了烟叶外观质量、物理性状、化学成分和评吸质量评价指标间的典型相关性。结果表明:烟叶外观质量、物理性状、化学成分和评吸质量评价指标间均存在显著典型相关关系,烟叶化学成分与评吸质量关系最密切,其次是外观质量与物理性状;烟叶质量不同评价指标的关系程度是不一样的,在烟叶质量组间关联上起主要作用的外观质量评价指标是成熟度、叶片组织结构和发育状况,物理性状评价指标是叶片厚度、单叶重和叶质重,化学成分评价指标是烟碱和还原糖,评吸质量评价指标是香气量、香气质和灰色。利用典型相关分析来简化烟叶质量评价指标是可行的。

Canonical correlations of sensory quality,physical property,chemical components,and smoking quality were analyzed respectively using flue-cured tobacco samples from tobacco-growing areas of Hunan province.Results indicated that the evaluating indices of above mentioned quality characters all showed significant canonical correlations.Relationship between chemical components and smoking quality was the most significant followed by relationship between sensory quality and physical property.Characters such as maturity,leaf organization and growth status,physical property such as leaf thickness,weight per leaf,and weight per unit leaf area,chemical components such as nicotine and reducing sugar, and smoking quality such as aroma quality,aroma quantity,and ash color played important roles between any two quality groups relationship.Quality evaluating indices in flue-cured tobacco by utilizing canonical correlation analysis can be simplified.
