Factor analysis of comprehensive physical properties of lfue-cured tobacco in Henan province and regularity research thereof
摘要
Abstract
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.关键词
