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。
[ Objective ] Leaf curing characteristics of flue-cured 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 flue-cured 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.
