| 摘 要： | 对2009—2010年广西百色8个植烟县92个烤烟样品的主要化学成分进行了特征分析和聚类。结果表明:百色烤烟主要化学成分较适宜和协调,钾高、氯低特征较为明显,钾、总氮和氮碱比稳定性高;上部烟叶化学成分较中部烟叶适宜;糖和淀粉含量在年度间出现较大波动,烟碱含量稳定;化学成分(除总氮外)在地区间存在显著差异。将8个产烟县按化学成分特性聚类,靖西、德保、西林、田林、隆林、那坡可聚为一类,这些植烟区烟叶各种化学成分较为适宜,是百色烟叶的主产区;乐业和凌云可聚为一类,这些植烟区烟叶糖含量较高,烟碱和挥发碱含量较低。

| Abstract: | The major chemical properties of 92 tobacco samples from 8 counties in tobacco growing regions of Baise, Guangxi province collected in 2009 and 2010 were analyzed and clustered. The results indicated that the chemistry of flue-cured tobacco in Baise was suitable and harmonious with high potassium and low chlorine content and high stability in contents of potassium, total nitrogen and total nitrogen to nicotine ratio. The chemistry of the upper leaf was more suitable than that of the middle leaf. The contents of total sugar and starch were much different between years but nicotine content was stable. The difference of chemical components of tobacco samples among the eight regions was significant except for total nitrogen. The leaves from Jingxi, Debao, Xilin, Tianlin, Longlin and Napo counties were clustered into one category based on chemical property clustering, which represents the main tobacco growing areas of Baise, in which the chemistry was more suitable and harmonious. The leaves from Leye and Lingyun were clustered into another category, in which the content of sugar was slightly higher but the contents of nicotine and volatile alkali were slightly lower. |
