为研究烤烟成熟期间不同阶段控水处理对烤烟香气及主要化学成分的影响,采用盆栽,分别在烤烟叶片处于定长、欠熟、适熟3个阶段将土壤相对含水率控制在40%和80%,测定烟叶挥发性香气成分及主要化学成分的含量.结果表明:烤烟成熟过程中,短时干旱处理后西柏烷类物质、质体色素降解物、美拉德反应产物和芳香族等香气物质含量比对照高,而持续干旱处理时这些物质含量比对照低,越临近烟叶定长的干旱对香气物质含量影响越大;烤烟成熟期间,任意阶段较短时间的干旱对香气物质形成有利,但持续干旱对香气形成不利.打顶后的间断干旱,水溶性糖和还原糖含量升高,总氮和烟碱含量也升高,欠熟期、适熟期干旱和整个成...

Effect of soil moisture on aroma and chemical components of flue-cured tobacco during various mature stages was studied. Tobacco plants were grown in pots and relative soil moistures were controlled at 40% or 80% of every treatment at different stages i.e. defining length stage, immature stage, and mature stage. Results indicated that content of cembranoids, carotenoids, Maillard chemical substances, and aromatic fragrance substances of flue-cured tobacco increased through short- time drought after topping, while continuous drought was disadvantageous to the formation of those latent fragrant ...
