| 摘 要： | 【目的】研究不同采收成熟度与烟叶品质和可应用性的关系，为提高烤烟品质和工业应用提供理论依据和技术参考。【方法】通过烟叶不同田间外观特征设置不同采收成熟度处理，分析不同成熟度对烤后烟叶外观质量、物理特性、化学成分、感官质量等的影响。【结果】下部不同成熟度烟叶外观质量无差异，中部和上部成熟烟叶的外观质量较尚熟和过熟好；上部尚熟、中部尚熟或成熟及下部尚熟烟叶物理性状较好。3个部位不同成熟度烟叶总糖、钾离子、还原糖、氯离子、总氮含量及糖碱比、钾氯比均在较适宜范围，内在质量较好。感官评吸结果表明，上部成熟烟叶吃味醇和，刺激性和劲头较小，余味较好；中部成熟烟叶香气质最好，浓度、刺激、杂气、劲头较小；下部尚熟烟叶香气量好，浓度适宜，吃味醇和。【结论】景东地区烟叶下部尚熟及中、上部成熟时采收有利于提高烤烟叶品质。

| Abstract: | Objective]The relations between different harvest maturity and tobacco quality as well as its applicability were investigated to provide theoretical and technical references for improving the quality of flue-cured tobacco leaves and industrial application. Method] Based on the different appearance characteristics of tobacco leaves, different harvest maturity treatments were set to analyze the effects of different maturity on appearance quality, physical characteristics, chemical composition and smoking quality of the flue-cured tobacco leaves. Result]The results showed that there is no difference about the appearance quality of the lower leaves with different maturity. As for the appearance quality of the middle leaves and upper leaves, maturity were better than proper maturity and over-maturity. Physical indicators of the upper leaves with proper maturity, the middle leaves with proper maturity or maturity and the lower leaves with proper maturity were relatively superior. The contents of main chemical components（total sugar, potassium ion, reducing sugar, chloride ion, total nitrogen, sugar-nicotine ratio, potassium- chlorine ratio）in tobacco samples of different parts with different maturity were at a right level, and the inner quality was good. Smoking test results showed that the taste of the upper leaves with maturity was pure and mild with little irritancy and strength, and the aftertaste was good. The smoking aroma quality of the middle leaves with maturity was the best due to little smoke con- centration, offensive odor, irritancy and strength. The volume of aroma of the lower leaves with proper maturity was good. Its smoke concentration was suitable, and the taste was pure and mild. Conclusion]Quality of tobacco leaves would be improved when the lower leaves at premature staze, and the middle and uDoer at mature staze in Jinzdonz Countv.Yunnan Province. |
