湖南烤烟品种湘烟3号烘烤特性研究
摘要[目的]摸清湖南郴州桂阳县新引进烤烟品种湘烟3号的烘烤特性。[方法]以湖南当地的主栽品种云烟87为对照，研究了暗箱试验和烘烤过程中湘烟3号中部叶的变黄、失水规律以及烤后烟叶经济性状。[结果]试验表明，暗箱试验中，湘烟3号变黄、失水较快，褐变速度快但滞后；湘烟3号色素含量低，烘烤过程中降解快且彻底，类叶比较高，易变黄；湘烟3号变黄期失水较慢，定色期大幅度失水，失水协调性较好。[结论]研究可为优化湘烟3号烘烤的工艺，充分彰显该品种特色提供参考依据。

Abstract[Objective] Leaf curing characteristics of fluecured tobacco variety Xiangyan No.3 from Guiyang County， Chenzhou City， Hunan Province was investigated. [Method] With Yunyan 87 as the control variety， yellowing of middle part leaf， water loss law of Xiangyan No.3 under dark condition and curing process were studied， as well as the economic traits of fluecured tobacco leaf. [Result] The results showed that Xiangyan No.3 leaf yellowing and water loss was faster， easy to browning but was hysteresis under dark condition； Xiangyan No.3 had low content of pigment， the pigment degradation speed was fast during curing process， the ratio of chlorophyll and carotenoid was high， the speed of yellowing was fast； the water loss rate was slow in yellowing stage and was fast in fixing color stage， the coordination of leaf dehydration was good. [Conclusion] The study provides reference basis for optimizing curing technique of Xiangyan No.3 and fully highlighting the characteristics of the species.
