1、大理烟区烤烟矿质元素与感官质量的灰色关联分析摘要:步提高烤烟质量,以大理烟区云烟87、K326和红花大金元3个主栽烤烟品种的上部叶、中部叶和下部叶为研究对象,对其矿质元素含量与感官质量进行测定和评价,并采用灰色关联法对矿质元素与烟叶感官质量之间的关系进行分析。结果表明:(1)不同烤烟品种不同部位烟叶矿质元素的含量均有较大程度差异,3个品种的上部叶钙、镁、铜、锌、铁、猛、硼等7种元素,以及中部叶钙、镁、铜、锌、铁等5种元素含量均有显著差异。(2)各品种烤烟感官质量表现为中部叶优于下部叶与上部叶,上部叶的香气质、香气量
2、、劲头与烟气浓度得分明显高于下部叶,而燃烧性与灰色得分明显低于下部叶;各感官质量指标在不同品种间有较大差异。(3)烤烟中不同的矿质元素中锌元素与感官质量中劲头的灰色关联度达到最大值,为0.55&硼元素对多种感官质量指标均有较大程度的影响。不同品种矿质元素的含量与感官质量差异较大,因此可以针对不同烤烟品种使用矿质元素肥料以促进烤烟对矿质元素的吸收,进而提高烤烟感官质量。关键词:烤烟;品种;部位;矿质元素;感官质量;灰色关联分析中图分类号:S517文献标识码:ADOI编码:10.3969/j.issn.1006-650
