摘要：

采集湖南烟区2007年B2F、C3F、X2F3个等级烤烟样本195份，分析了烤烟焦油量的区域特征，并进行了聚类评价。结果表明：湖南烟区B2F、C3F、X2F等级烤烟焦油量平均值分别为19.94 mg/支、15.93 mg/支、11.58 mg/支，表现为B2F＞C3F＞X2F；C3F、X2F等级烤烟焦油量变异系数大；B2F、C3F等级烟叶焦油量在3大生态区域间差异不显著，但X2F等级烟叶差异极显著，表现为湘西北烟区相对较高，而湘中烟区相对较低；B2F等级烟叶焦油量不同地区间差异不显著，但C3F 、X2F等级烟叶差异显著，烤烟焦油量表现为湘西州、常德市烤烟焦油量相对较高，张家界市、永州市烤烟焦油量相对较低，长沙市除X2F等级烤烟焦油量较低外，B2F、C3F等级烤烟焦油量都较高；聚类分析将湖南烟区焦油量分为下部烟叶低焦油型、中上部烟叶低焦油型、下部烟叶高焦油型、中上部烟叶高焦油型等4大类型。

Abstract:

The regional characteristics of tar contents were analyzed by collecting the total of 195 flue-cured tobacco samples with 3 grades(B2F, C3F, X2F) in 2007 from Hunan tobacco-growing areas. The results showed that the means of tar contents in the flue-cured tobacco leaf of B2F, C3F, X2F were 19.94 mg/cigarette,15.93 mg/cigarette, 11.58 mg/cigarette, respectively. The coefficient of variation of C3F and X2F were big. The difference of B2F and C3F were not significant but the difference of X2F was extremely significant in different ecological areas. For same grade, the tar contents of flue-cured tobacco leaves in Northwest Hunan was higher and that in Center Hunan was lower than others. The difference of B2F were not significant but the difference of C3F and X2F was extremely significant in different locations. For same grade, the tar contents of flue-cured tobacco leaves in Xiangxi and Changde were the highest, that in Yongzhou and Zhangjiejie were comparative lower. For B2F and C3F grades, the tar contents of flue-cured tobacco leaves in Changshai were the highest, but X2F grade in Changsha was comparative lower. The tar contents of flue-cured tobacco leaf in Hunan tobacco-growing areas is divided into four types with the cluster analysis, less tar contents of lower tobacco leaf, less tar contents of upper and middle tobacco leaf, higher tar contents of lower tobacco leaf, higher tar contents of upper and middle tobacco leaf.
