通过简单相关分析、通径分析及方差分析，研究了125份烤烟烟叶物理特性（9项）与常规化学成分及外观质量间的关系。结果表明，各项物理指标之间以叶片厚度与叶质重关系最为密切，其相关系数r＝0.808；叶质重、填充值和质量燃烧速率与常规化学成分及其派生值间的相关性最显著。叶片厚度、叶质重与总钾、糖碱比、氮碱比和钾氯比均呈极显著负相关关系，且都与钾的相关性最高，而质量燃烧速率则相反，与总钾含量、糖碱比、氮碱比和钾氯比呈极显著正相关关系。平衡含水率与填充值呈极显著负相关关系，烟叶拉力与化学成分间的关系不显著。烤烟物理特性方面，叶质重对烟叶外观质量的影响最大，与烟叶颜色、身份和色度指标均有显著差异，而与成熟度、叶片结构和油分指标间的关系不显著。

The relationship between the physical properties and regular chemical compositions and appearance quality were explored by simple correlation analysis, path analysis, and variance analysis of 125 samples of flue-cured tobacco. The results showed that the leaf thickness and leaf weight had the closest relationship (r = 0.808 ). There were very significantly negative correlation between leaf thickness, leaf weight, total potassium, sugar/alkali, nitrogen/alkali, and K/Cl, which all had significant correlation with potassium. On the other hand, there are significantly positive correlation between mass burning rate and total potassium, sugar/alkali, nitrogen/alkali, and K/Cl. Also there were very significantly negative correlation between equilibrium moisture content and filling power, but the relationship between tensile strength and chemical composition of tobacco was not significant. For the physical indices, leaf weight had the most important influence on the appearance quality of tobacco leaves, and had significant influence on leaf color, figure, and chrome, but little effect on maturity, leaf structure, and oil content.
