摘要

为阐明毕节烤烟糖碱比的地域分布特点及其与感官品质的关系,对毕节烟区的342份C3F初烤烟叶样品糖碱比进行了描述性统计分析和聚类分析,并对烟叶糖碱比与感官品质指标进行了回归分析。结果表明:毕节烟区烤烟中部叶糖碱比平均值为9.64±3.80,变异系数39.36%,其中96.4%的样品烟叶糖碱比在4.00～20.00之间;随海拔高度的增加烟叶糖碱比增大,糖碱比在不同海拔间、产区间存在显著差异。聚类分析结果将毕节市8个产区烟叶糖碱比划分为3类,第Ⅰ类群烟叶糖碱比为8.39±2.48,包括织金、黔西、纳雍、七星关4个产烟县、区;第Ⅱ类群烟叶糖碱比为9.82±4.62,包括大方和金沙两个产烟县;第Ⅲ类群烟叶糖碱比为11.59±3.74,包括赫章、威宁两个产烟县。毕节产区烟叶糖碱比在4.00～28.00范围内,烟叶糖碱比与除燃烧性外的感官品质指标呈极显著的回归关系;烟叶糖碱比在8.00～22.00范围内,其感官品质较好。
To reveal the distribution characteristics of reducing sugar/nicotine ratio of flue-cured tobacco in Bijie tobacco growing areas and relationship thereof with sensory quality, the reducing sugar/nicotine ratio of 342 samples of C3 F from Bijie was analyzed by descriptive statistical analysis and cluster analysis. Regression analysis was conducted between reducing sugar/nicotine ratio and sensory quality. The results showed that the mean value of reducing sugar/nicotine ratio was 9.64±3.80 with the coefficient of variation of 39.36%, and the reducing sugar/nicotine ratio of 96.4% of the samples fell in the range of 4.00 to 20.00. With the ascent of altitude, the reducing sugar/nicotine ratio of tobacco increased. Reducing sugar/nicotine ratio significantly differed between tobaccos from different areas and altitudes. Eight tobacco growing counties in Bijie were clustered into three categories on the basis of reducing sugar/nicotine ratio, Zhijin, Qianxi, Nayong and Qixingguan counties belonged to Category Ⅰwith the reducing sugar/nicotine ratio of 8.39±2.48, Dafang and Jinsha counties were in CategoryⅡwith the reducing sugar/nicotine ratio of 9.82 ± 4.62, Hezhang and Weining counties in Category Ⅲ with the reducing sugar/nicotine ratio of 11.59 ± 3.74. In the range of 4.00 to 28.00, the reducing sugar/nicotine ratio posed an extremely significant regression relationship with sensory quality indicators(except for combustibility). Tobacco offered better sensory quality when its reducing sugar/nicotine ratio was in the range of 8.00-22.00.
