为探索河南烤烟综合物理特性在产地、部位间的差异性和变化规律，检测了89个样品的6项物理指标并进行了因子分析、聚类及方差分析。结果表明：①各项物理指标在产地间的差异和在部位间的差异程度不同，其中抗张强度在产地间和在部位间均有高度统计学意义，叶片厚度、叶片密度在部位间的差异均极显著；填充值、阴燃时间和平衡含水率在产地间均有高度统计学意义。②综合物理特性在产地间的差异总体上大于部位间的差异。③依据综合因子得分和部位因素将89个烤烟样品分成了3个主组、9个亚组，使得同一亚组内烟叶的综合物理特性最为接近。研究结果有利于从总体上把握河南不同产地、不同部位的烤烟物理特性的优势与不足，为合理利用烟叶原料和分组加工提供参考。

To explore the difference and regularity of comprehensive physical properties of different parts of flue-cured tobacco from different areas in Henan province, 6 physical properties of 89 samples were determined and further studied through factor analysis, cluster analysis and variance analysis. Results showed that:①Physical properties showed differences on tobacco from different areas and different parts of tobacco and tensile strength had highly significant statistical difference. Leaf thickness and density showed highly significant difference on different growth parts of tobacco;filling value, smoldering time and equilibrium moisture content had highly significant difference on tobacco from different growing areas.②Comprehensive physical property had greater difference on tobacco from different areas than on different parts of tobacco. ③ 89 flue cured tobacco samples were divided into 3 main groups and 9 subgroups according to factor variable scores and different growth parts of tobacco, making comprehensive physical property in the same sub group share the most similarity. Research results were conducive to identify advantages and disadvantages of physical property of different growth parts of Henan flue-cured tobacco from different growing areas so as to provide reference for the rational use of tobacco resources and group processing.
