摘要
测定了2002、2003年全国6产区170个烤烟烟叶样品的总挥发酸含量，并对其差异显著性进行了分析。结果表明：①各产区烟叶挥发酸含量集中在0．20％～0．40％范围内，各产区烤烟挥发酸含量差异极显著，含量由高到低依次是福建、四川会理、贵州毕节、山东临沂、河南宜阳；②同一地区相同等级不同品种烟叶挥发酸含量差异不大，其中福建永定的云烟85略高于福建长汀的K326，河南宜阳的中烟101略高于中烟100；③四川会理K326和贵州毕节云烟85三个部位相同等级烟叶的挥发酸含量均是2002年的高于2003年的，且云烟85高的幅度较大，但山东临沂NC82两年的差异不明显；④上部烟叶的挥发酸含量最高，中部叶次之，下部叶最低。不同产区烟叶挥发酸含量的部位差异幅度不一样。
The total volatile acid in 170 tobacco samples from 5 provinces of China grown in 2002 and 2003 were determined and compared. The results showed that： 1 ） the total volatile acids in tested tobacco samples were in the range of 0.20 % - 0.40 %, the differences of total volatile acids between tobaccos from different provinces were extremely significant, the provinces in the order of total volatile acid content were Fujian 〉 Sichuan 〉 Guizhou 〉 Shandong 〉 Henan; 2） there was no significant difference in total volatile acid content between different cultivars of the same grade, though, the content was slightly higher in Yunyan85 from Yongding, Fujian than that in K326 from Changting, Fujian and slightly higher in Zhongyan101 than that in Zhongyan100 both from Yiyang, Henan; 3） as for the leaves of the same grade, the total volatile acid content in K326 from Huili, Sichuan and Yunyan85 from Bijie, Guizhou in 2002 were higher than that in 2003, particularly in Yunyan85, however, the content in NC82 from Linyi, Shangdong changed little between 2002 and 2003; 4） the stalk positions in the order of total volatile acid content were upper leaf 〉 cutter 〉 lower leaf, and the ranges of the content varied with grown areas.
