2、含量。结果表明，与正常烟叶相比，烤坏烟的总糖、还原糖含量和糖碱比均大幅度降低，均为不适宜或极不适宜；烟碱、总氮和蛋白质含量明显提高。5种烤坏烟的总糖含量、还原糖含量的平均值，中部叶分别比正常烘烤的C3F低53．5％和50．6％，上部叶分别比比正常烘烤的B2F低39．6％和35．3％；中部叶烤坏烟的烟碱、总氮和蛋白质含量平均值分别比正常烘烤的C3F高31．4％、40．6％和28．6％，上部叶分别比正常烘烤的B2F高24．5％、36．4％和21_2％；中部叶烤坏烟的还原糖／烟碱平均值比正常烘烤的C3F低62．0％，上

3、部叶则比正常烘烤的B2F低47．8％。可见，烤坏烟的主要化学成分含量大多不适宜、不协调。关键词：烤坏烟；正常烟叶；化学成分；差异中图分类号：$572．01文章编号：1007．5l19(2014)03．0074—05DOI：10．13496~．issn．1007—5119．2014．03．015DiferenceofMainChemicalCompositionbetweentheNormalandPoorlycuredTobaccoLeavesinQiannanofGuizhouProvinceXIAOZhenj
