烟叶评吸质量与外观质量的相关性分析

Analysis of Correlation between Smoking Quality and Appearance Quality of Tobacco Leaf

以贵州遵义烟区主栽烤烟品种云烟87为材料,测定了3个等级(B2F、C3F和X2F)共计18个样品的评吸质量得分和外观质量因素得分,采用相关分析和逐步回归分析等方法,分析了评吸得分和外观质量因素的相互关系。结果表明:(1)遵义烟区烟叶的评吸总分与成熟度和叶片结构呈极显著的正相关关系;(2)通过逐步回归分析建立起来的回归方程Y=0.327+0.602X成熟度+0.252X叶片结构表明评吸质量与成熟度和叶片结构呈正相关,这2个因素对评吸质量的相关影响达到94.9%的程度。

Taking the mainly-cultivated flue-cured tobacco variety ＂Yunyan 87＂ in Zunyi city of Guizhou province as the tested material,the paper determined the scores of smoking quality and appearance quality of 18 tobacco leaf samples at 3 different grades（B2F,C3F and X2F）,and analyzed the correlation between the smoking quality score and appearance quality factors with correlation analysis and stepwise regression analysis methods.The results indicated that：（1） The smoking quality score was extremely significantly and positively correlated with the maturity and leaf structure.（2） Through stepwise regression analysis,a regression equation was built as follows： Y=0.327＋0.602Xmaturity＋0.252Xleaf structure,this equation showed that the smoking quality was positively correlated with the maturity and leaf structure,and these 2 factors had the influence degree of 94.9% on the smoking quality.
