| 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 s... |
