摘　　要：以烤烟品种K326、Y85、红大为材料，研究了云南保山市部分地区（海拔高度1500-2100m）丰栽烤炯品种B2F等级烟叶常规化学成分与种植海拔高度的关系。结果表明，各品种对海拔的敏感性不同，品口种间内在化学成分差异较大；K326对海拔高度比较敏感，其常规化学成分与海拔高度呈现一定的规律性，随着海拔的增加．其B2F等级烟叶总糖含量、还原糖含最增加，总氮含量、炯碱含量、K含量降低，且均达到显著或极显著水平；而红大与Y85规律性不明显。Using varieties K326, Y87and Hongda as material, the correlations between the plant altitudes （1500-2100 m） and the chemical components in different variety flue-cured tobacco upper leaves of grade B2F were analyzed. The results showed that different tobacco varieties had significant different adaptations to plant altitude. The chemical components of different variety flue-cured tobacco are different. K326 was sensitive to plant altitude, and the total sugar and the reduce sugar of K326 upper leaves （B2F） increased with the altitude, while the total nitrogen, nicotine and kalium of K326 upper leaves （B2F） decreased with the altitude. The regularity of correlations between the plant altitudes and the chemical components of Hongda and Y87 was not obvious.
