湘北烟区不同基因型烤烟鲜叶主要化学成分变化

Changes of Major Chemical Components in Flue-cured Tobacco Leaves of Different Genotypes in North of Hunan Tobacco-growing Areas

分析了湘北地区不同基因型烤烟鲜叶的主要化学成分。结果表明:G80和红大的总氮、烟碱、可溶性总糖、还原糖含量较其它品种高,而钾含量较低;V2、云烟87、云烟317各项指标含量居中;RG11总氮、烟碱、可溶性总糖、还原糖含量均较低,而钾含量较高。

The major chemical components of flue-cured tobacco leaves were analyzed in North of Hunan. The results indicated that content of total nitrogen, alkaloid, water-soluble sugar and reducing sugar were higher in G80 and Hongda, but Potassium was lower than others; Each index contents of V2,Yuyan87, Yuyan317 was in the middle; The content of total nitrogen, alkaloid, water-soluble sugar and reducing sugar were lower in RG11,and Potassium was higher.
