Keyword:  烤烟采收成熟度物理性状化学成分云南曲靖;
Abstract: 以云南曲靖主栽烤烟品种云烟97试材,研究了4个不同采收成熟度对烤后烟叶物理性状、化学成分的影响.结果表明:随着采收成熟度的提高,烟叶物理性状的最大叶宽、含梗率、叶片厚度呈现出先升后降变化趋势;化学成分中淀粉含量先增后减趋势;总氮、烟碱含量呈先减后增的趋势,钾、氯含量变化不大,还原糖、总糖及双糖差比例不协调,需要综合考虑烟叶物理性状和化学成分的协调性.云烟97不同部位烟叶适宜采用不同成熟度采收,其中下部叶适宜采收成熟度为处理XM4(叶面黄绿色,主脉变白2/3以上);中部叶以处理CM3(叶面浅黄色,8~9成黄;主脉变白3/4以上)采收最佳;上部叶以处理BM4(叶面全黄;主脉全白,有叶尖发白或焦尖现象)采收最佳.
