湖南浓香型烤烟常规化学成分与外观质量关系分析

Relationship between Regular Chemical Compositions and Appearance Quality of Flue-cured Tobacco in Hunan

对湖南省浓香型烟区2011—2012年111个烤烟样品的化学成分和外观质量进行了基本统计特征分析,并采用灰色关联分析研究了外观质量与常规化学指标之间的关系。结果表明,烟叶化学成分各项指标都是右偏态分布,外观质量除颜色和成熟度指标外,其它各指标是左偏态分布,烟叶总氮、总糖、烟碱含量与烟叶外观质量各项指标关系最密切,氯含量与烟叶外观质量关系最远。

The regular chemical component indexes of 111flue-cured tobacco samples in Hunan Province in 2011 —2012 were analyzed,and the relationship between their appearance quality and regular chemical component indexes was studied by using grey relation analysis.The results indicated that the indicators of leaf chemical composition were all right-skewed distribution, apart from color outside and mature degree, all other appearance quality indicators were skewed left, the closest relationship with the appearance of quality was total nitrogen, total sugar and nicotine. The most distant relationship with the appearance of quality was chlorine content.
