摘要:为了明确烤烟上部叶片质量评价指标间的相关关系,以全国 8 个主产烟区 122 份 B2F 烟叶样品为材料,对样品的
外观质量、物理特性、化学成分、感官质量进行相关分析。结果表明,烟叶总糖、还原糖与身份、平衡含水率呈极显著正相
关,与成熟度、含梗率、叶片厚度呈极显著负相关;总植物碱、总氮与成熟度、含梗率呈极显著正相关,与身份呈极显著负
相关;烟叶感官质量各个指标与平衡含水率、总糖、还原糖呈极显著正相关,与总植物碱、总氮呈极显著负相关。研究认为,
烟叶成熟度、身份、叶片厚度、含梗率、平衡含水率与化学成分的关系较为密切,烟叶化学成分对感官质量有明显的影响。

Abstract: The purpose of this study was to investigate the correlation between the quality indices of upper leaves in flue-cured
o. 122 samples of upper leaf (B2F) were collected from 8 main production areas in China, and relationships between
appearance quality, physical property, ponents and sensory quality of the samples were studied. The results showed that
the total sugar and reducing sugar were extremely significantly and positively correlated with the leaf body and the equilibrium
moisture content, and
