采集湖南烟区上、中、下3个部位烤烟样本180份,分析了烤烟焦油量的生态地域差异和部位差异.结果表明:湖南烟区上、中、下3个部位烤烟焦油量均值分别为19.9、16.9和12.71 mg/支,主要分布区间分别为17.8～20.8、13.4～16.0和10.2～14.0 mg/支,烤烟下部叶焦油量变异系数相对较大;生态区域间烤烟焦油量差异显著,表现为湘西北烟区较高;地区间烤烟焦油量差异显著或极显著,表现为湘西州烤烟焦油量相对较高,永州市、长沙市烤烟焦油量相对较低;在生态区域分布上,烤烟上部叶焦油量存在从西北往东南方向逐渐降低、从西南往东北方向先升高后降低的趋势,烤烟中部叶焦油量存在从西北往东南方向先降低后升高、从...

The tar deliveries of lower） grown in Hunan tobacco 180 flue-cured growing areas tobacco samples from 3 stalk positions （upper, middle and were analyzed. The results showed that： the means of tar deliveries of upper, middle and lower leaves were 19.9, 16.9 and 12.71 mg/cig. , respectively, whose main distributing ranges were 17. 8-20. 8, 13. 4-16. 0 and 10. 2-14. 0 mg/cig. , respectively.
