以云南保山烟区高海拔主栽烤烟品种‘云烟100’为材料,系统研究了夜间大田环境温度升高对烤后烟叶理化性状、微量营养元素及主要致香前体物质量分数的影响。结果表明:(1)烟株各部位烟叶叶宽和单叶重显著增加,上部叶叶长和含梗率显著降低,中下部叶叶片厚度显著增加。(2)所有处理烟叶两糖差均较对照不同程度降低,烟碱和氯质量分数显著降低,钾质量分数显著提高,总氮质量分数提高。(3)夜温升高使上部叶Cu,Fe质量分数显著降低,Zn,Mn质量分数显著增加;中部叶Fe质量分数显著降低,Zn,Mn质量分数显著增加;下部叶Cu, Zn, Mn质量分数显著降低,Fe质量分数显著增加。(4)下部叶叶黄素、β-胡萝卜素、绿原酸、芸...

In this study, taking ‘ Yunyan100’ as sample, we systematically studied the effect of the increased night temperature on the physicochemical properties, microelement and content of main aromatic compounds in flue-cured tobacco produced in the high-altitude area of Baoshan,during their growth duration. The results showed : (1) Leaf width and simple leaf weight in all parts of tobacco significantly increased, while length and stem ratio of upper leaves greatly decreased and thickness of middle and lower leaves increased largely. (2) The differe...
