摘要
[目的]揭示不同烟叶质量评价指标的关联程度,缩减烟叶质量评价指标。[方法]运用描述统计和典型相关统计分析方法研究了曲靖烤烟外观质量和化学成分含量状况及其相互关系。[结果]分析表明,两大烤烟质量评价指标间存在显著的典型相关性,化学成分含量与外观质量存在密切的关联程度;不同烤烟质量评价指标的关联程度不一样,在烤烟质量组间关联上起主导作用的化学成分评价指标是还原糖、总氮、烟碱和氯,外观质量评价指标是成熟度、结构、身份和油分。[结论]研究可为曲靖乃至云南烟区清香型烤烟的生产工作提供理论指导。
[Objective] To reveal correlation degree of different tobacco quality evaluation index,shorten tobacco quality evaluation index.[Method] The relationship of chemical components and appearance quality of flue-cured tobacco leaves in Qujing were investigated by using descriptive statistics and canonical correlation analysis.[Result] The results indicated that：two kinds of quality evaluating indices of fluecured tobacco leaves showed significant canonical correlations.Chemical components such as reducing sugar,total N,nicotine and Cl-,appearance quality such as maturity,structure,body and oil played important roles between two quality groups relationship.[Conclusion] The study can provide theoretical guidance for production of flavor flue-cured tobacco in Yunnan tobacco area.
