不同品种烤烟烟叶烟碱与烟气烟碱的关系研究

Study on Correlation between Nicotine in Smoke and Nicotine in Leaves of Flue-Cured Tobacco with Different Varieties

[目的]研究烤烟烟叶烟碱与烟气烟碱含量的相关性。[方法]对同一地区生产的11个品种不同等级烤烟烟叶的烟碱含量和烟气烟碱含量进行检测和相关性分析。[结果]不同品种烤烟烟叶的烟碱含量和烟气烟碱含量均表现为上部叶>中部叶>下部叶;烟叶烟碱进入烟气中的比例为4.06%～8.64%,呈现出下部叶>上部叶>中部叶的规律;南江3号的烟叶烟碱含量显著低于其他品种,但烟叶烟碱进入烟气烟碱的比例显著高于其他品种;K326品种各部位之间烟碱的转化率较为稳定。[结论]烤烟烟叶烟碱含量与烟气烟碱含量具有显著相关性,烟叶烟碱进入烟气烟碱的比例受品种和部位的影响。

[ Objective ] The aim was to study the correlation of between.the nicotine in the smoke and the nicotine in the leaves of flue-cured tobacco. [ Method] The nicotine contents in the smoke and tobacco leaves of 11 flue-cured tobacco varieties with different grades planted in the same area were determined and their correlations were studied. [ Result ] The nicotine contents in smoke and tobacco leaves in different fluecured tobacco varieties followed the order of upper leaf 〉 middle leaf 〉 lower leaf. The proportion of the nicotine in the tobacco leaves ente- ring the smoke was 4.06% ～ 8.64% and showed a trend of lower leaf 〉 upper leaf 〉 middle leaf. The nicotine contents in the leaves of Nanjiang 3 was significantly lower than that of other varieties, but the ratio of the nicotine in the tobacco leaves entering the smoke was apparently higher than other varieties. The conversion rate of the nicotine in K326 among different stalk positions was more stable. [ Conclusion] There was significant correlation of nicotine between the nicotine in the smoke and the nicotine in the leaves of flue-cured tobacco and the ratio nicotine ratio in the tobacco leaves entering the smoke was affected by the variety and the stalk position.
