烤烟香型与产区及品种的关系研究

Relationships of Flue-cured Tobacco Flavor Type with Growing Area and Variety

  • 摘要: 为研究烤烟香型与产区及品种的关系,选取国内14省烤烟产区13个品种的127份不同香型的烟叶样本进行化学成分分析,依据相关分析筛选出合适的变量,并进行香型产区的聚类分析及香型与产区、品种的对应分析。结果表明:①采用多序列相关分析法筛选出5个与香型呈高度相关的指标,分别为总糖、芸香苷、锌、硬脂酸和苯甲醛。②依据筛选变量可将不同香型烤烟中部烟叶的产区特征聚为3类,与当前主观定性判定香型的结果相吻合,且2012年的验证数据与2011年相一致,显示了香型产区聚类结果的准确性。③对应分析结果显示,不同产区、品种烤烟的香型特征存在较大差异,且产区对香气风格的影响比品种大;具有相似香型特征的产区和品种互相邻近,可较为直观地分为3类,与聚类分析的结果基本一致。该研究结果为不同香型烤烟的区域划分及烤烟栽培品种的选择提供了理论依据。

     

    Abstract: In order to study the relationships of flavor type with growing area and variety, 127 samples of flue-cured tobacco of 13 varieties were collected from 14 provinces in China, and the chemical components in the samples were analyzed. The appropriate variables were screened by correlation analysis, then, the cluster analysis of flavor types and growing areas and the correspondence analysis of flavor type versus growing area and variety were carried out. The results showed that: 1) 5 variables(sugar, rutin, zinc, stearic acid and benzaldehyde) which highly correlated to flavor type were identified by multiple sequence correlation analysis. 2) The growing area characteristics of middle leaves of different flavor types could be clustered into 3categories on the basis of these variables, it agreed with the results of subjective evaluation. The validation data of 2012 were consistent with those of 2011, it demonstrated the accuracy of clustering results. 3) The results of correspondence analysis showed that the flavor type characteristics of tobacco differed obviously between different varieties and different areas, andgrowing area affected aroma style more significantly than did variety. Growing areas and varieties with similar flavor type characteristics were adjacent to each other and could be visually classified into three categories, which were basically consistent with the results of cluster analysis. This study provides a theoretical basis for the demarcation of flue-cured tobacco planting for different flavor types and the selection of applicable cultivars for tobacco production.
