云南新烟区与津巴布韦KRK26烟叶化学成分相似性分析
Similarity Analysis of KRK26 Tobacco Chemical Components in Yunnan New Planting-areas and Zimbabwe
摘要
Abstract
Routine chemical components and flavor matter in the upper leaves, the middle leaves and the lower leaves of tobacco variety KRK26 from the 26 new tobacco-growing areas in Yunnan Province and the main tobacco-planting areas in Zimbabwe were analyzed by using comparative analysis and included angle cosine. The results showed that the difference on tobacco-leaves from the new tobacco-growing areas in Yunnan Province and the main tobacco-planting areas in Zimbabwe were mainly caused by the contents of polyphenol, polybasic and flavor matter not the contents of routine chemical components such as total sugar. Total similarity of the content of routine chemical components in tobacco-leaves from the new tobacco-growing areas in Yunnan Province and the main tobacco-planting areasin Zimbabwe was high. And similarity of the content of routine chemical components in the lower leaves from these areas was highest. The similarities of flavor matter in tobacco-leaves with different positions from the two kinds of places were different. Similarities in the upper leaves were relatively low, followed by the lower leaves and similarities in the middle leaves were highest. Included angle cosine values of the middle leaves from the No. 5 farm of Marondera in Zimbabwe and the 8 counties in Yunnan Province such as Shidian, Yunxian, Gengma, Cangyuan, Shuangjiang, Zhenyuan, Jinggu and Midu were more than 0. 99, especially the included angle cosine values of the middle leaves from Shuangjiang and Zhenyuan and the No. 5 farm of Marondera in Zimbabwe were more than 0. 998. The similarities of flavor matter in the middle tobacco-leaves from these two areas and the No. 5 farm of Marondera in Zimbabwe were very high.关键词
