摘　　要：[目的]探讨不同烤烟品种上部烟叶采用集中采收的适用性。[方法]对不同烤烟品种(K326、云87和粤97)采取集中一次性采收的效果进行了比较。[结果]各品种在不同评价指标中具有各自的优势。集中采收方式下,云87和粤97烟叶开片较好,含梗率和叶厚度相对较小,化学成分较协调;K326品种单叶重和叶密度相对较小,烟碱含量较高,总糖和还原糖含量较低,整体表现较差。[结论]集中采收上部烟叶在不同烤烟品种上的适宜性大小为云87≥粤97>K326。为提高上部烟叶质量提供了理论依据。[Objective] The aim was to study effects of concentration harvesting on physicochemical characters of different varieties of flue-cured tobacco upper leaves.[Method] Effects of different varieties of flue-cured tobacco from concentration harvesting were compared.[Result] Each tobacco variety had its own advantages in all the evaluation indexes.Yun 87 and Yue 97 had better open degree and relatively small stem percentage and leaf density,meanwhile their chemical compositions were more coordination under the concentration harvesting method.K326 had relatively minor single leaf weight and leaf density,a higher content of nicotine and lower contents of total sugar and reducing sugar,but its overall performance was worse.[Conclusion] The suitability of concentration harvesting method in different varieties upper leaves was in order of Yun 87≥Yue 97K326.The research provides theoretical basis for improving the quality of flue-cured tobacco upper leaves.
