不同移栽期对‘云烟85’烟叶质量风格特色的影响

摘要

采用随机区组试验,研究了不同移栽期对‘云烟85’烟叶质量风格特色的影响。结果表明：当地提早移栽的烟叶外观质量总体上比对照烟叶好,表现为烟叶颜色橘黄,结构疏松,成熟度成熟,身份较适中,油分较足,色度较均匀、饱满。特别是中上部烟叶,表现出随着当地移栽期的提前,烟叶外观质量逐渐变好的趋势。推迟移栽的烟叶外观质量均比对照烟叶差。试验中随着当地移栽期的提前,‘云烟85’烟叶香型呈现由浓香逐步向清香转变的趋势,烟叶甜感呈现由焦甜逐步向清甜转变的趋势；烟叶香气质变好,香气量更足,杂气变轻,烟气变细腻,浓度增大,劲头更适中,刺激性变小,余味变好,感官质量综合得分增高。不同移栽期处理对烟叶常规化学成分含量的影响不明显。方差分析表明,4个移栽期处理在烟叶感官质量特征各指标上的差异均达到显著或极显著水平,在烟碱、总糖、还原糖、钾和氯含量的差异均不显著。%In order to highlight the unique style and improve the quality of tobacco leaves by give full play to the climatic resource advantages,two randomized block experiments were conducted to research the effects of transplanting date on quality and unique style of flue-cured tobacco cultivar‘Yunyan 85’.The re-sults showed that the appearance quality of tobacco leaves of early transplanting were better than that of control group leaves,especially in the middle leaves and upper leaves with orange color of uniform and plump,loose structure,mature feature,moderate identity,enough oil.On the contrary,the appearance quali-ty of tobacco leaves of delaying transplanting were inferior to that of control group leaves.The full-bodied flavor and baking-sweet flavor of flue-cured tobacco leaves faded down,the fen-flavor and fen-sweet inten-sified,the aroma quality smelled better,the aroma quantity become more plentiful,the offensive odor smelled lighter,the smoking become more exquisite,the taste strength increased,the physiological strength was more moderate,the irritation decreased,the remaining taste tasted better,and the composite score of smoking quality increased with the transplanting date moved up in the local.The influence of transplanting date on the content of tobacco conventional chemical composition was not obvious.Analysis of variance in-dicated that there were significantly or extremely significantly difference among four transplanting date treatments in all smoking quality indexes,but there was no significantly difference in some chemical compo-sition indexes such as nicotine,total sugar,reducing sugar,potassium and chlorine.
