云南省新烟区烟叶与津巴布韦烟叶主要化学成分比较分析

Comparison of main chemical components of flue-cured tobacco between Yunnan new tobacco growing areas and Zimbabwe

对云南省文山、保山、临沧、普洱4个新烟区与津巴布韦马龙德拉、宾杜拉、奇诺伊3个烟区生产的‘KRK26’烟叶的主要化学成分进行了比较分析。结果表明新烟区烟叶还原糖、氯、多酚、挥发酸、钙含量和pH值与津巴布韦烟叶有显著性差异。主要化学成分的主成分分析结果表明普洱烟叶与津巴布韦烟叶相似性较高,文山烟叶与津巴布韦烟叶相似性稍低;津巴布韦烟叶中马龙德拉烟叶与云南省新烟区烟叶相似性较高,宾杜拉、奇诺伊烟叶与云南省新烟区烟叶相似性稍低。

The main chemical components of flue-cured tobacco KRK26 between Yunnan new tobacco growing areas（Wenshan,Baoshan,Lincang,Pu＇er）and Zimbabwe（Marondera,Chinoy,Bindura）were compared in our study.The results showed that there were significant differences between new tobacco growing areas and Zimbabwe in the content of reducing sugar,chloride,polyphenols,volatile acids,and calcium and pH value.Principal component analysis showed that Pu＇er leaf had higher similarity with Zimbabwe leaf while Wenshan leaf had a little lower similarity with Zimbabwe leaf.Marondera leaf had higher similarity with new tobacco growing areas of Yunnan while Bindura and Chinoy leaf had a little lower similarity with new tobacco growing areas.
