1、安徽农业科学.JournalofAnhuiA.Sci.2015,43(20):288—290,339责任编辑李菲菲责任校对况玲玲贵州烟区烤烟品种云烟87主要化学成分特征分析张丽,姬厚伟,黄锡娟,刘义萍,刘剑,何军,段凯(贵州中烟工业有限责任公司技术中心,贵州贵阳550009)摘要[目的]分析贵州主产区烤烟品种云烟87主要化学成分,掌握其特点。[方法]对贵州省主产烟区烤烟品种云烟87主要化学成分进行分析,并与云南主产区云烟87化学成分进行比较。[结果]分析表明,贵州烟区烤烟品种云烟87主要化学成分总体协调,总糖含量、还原糖
2、含量较高,钾含量略低,糖碱比略高,总植物碱含量、氯含量、总氮含量、氮碱比、钾氯比均较适宜;钾氯比的变异系数最大,总糖和还原糖含量的变异系数最小;云烟87烤烟总糖含量、总植物碱含量和糖碱比在不同等级样品间差异显著;氯含量、钾含量和氮碱比在不同地区间差异显著。贵州云烟87样品总糖含量、氯含量显著低于云南云烟87样品,钾氯比显著高于云南云烟87样品。[结论]研究可为贵州烤烟云烟87的优质生产和合理布局提供理论依据。关键词贵州;云烟87;主要化学成分中图分类号S572文献标识码A文章编号0517—6611(20l5)20—288
