湖北环神农架区域烤烟中性致香物质分析

对湖北环神农架烟区烤烟样品进行中性致香物质分析,并与津巴布韦优质烟样进行比对,结果表明：房县、保康、兴山地区烟叶的致香物质已基本达到或超过津巴布韦水平,神农架地区与津巴布韦相比差距稍大；在该区域的生态条件下,烤烟种植品种‘K326’的中性致香物质含量高于‘云烟87’；烟叶部位间上部叶(B2F)中性致香物质含量最高,中部叶(C3F)次之,下部叶(X2F)最低。

Analysis on neutral aroma components of flue-cured tobacco from Shennongjia region of Hubei Province

The neutral aroma components of flue-cured tobacco samples from Shennongjia tobacco-growing region of Hubei Province were analyzed and compared with the high-quality tobacco samples from Zimbabwe. The results indicated that the neutral aroma component contents of flue-cured tobacco samples from Fangxian, Baokang and Xingshan regions basically reached or exceeded those from Zimbabwe, but there was more obvious difference between samples from Shennongjia region and Zimbabwe. The neutral aroma component contents of K326 were more than Yunyan87 in the ecological condition of Shennongjia region. Moreover, the contents of neutral aroma components showed difference in different leaf position, indicating the upper leaf (B2F) was the highest, the middle leaf (C3F) took the second place, and the lower leaf (X2F)was the lowest.
