| 摘 要： | 为明确湘烟7号在烘烤过程中烟叶失水和色素降解的特性,以云烟87为对照,采用电烤箱试验方法,探究不同部位烟叶的叶片与叶脉失水特性及叶绿素与类胡萝卜素的降解特性。结果表明,湘烟7号叶片失水高峰早于对照;湘烟7号中、下部叶易烤特性优于对照,上部叶相反;在变黄前期（24h）,湘烟7号叶绿素a降解速率显著低于对照,而叶绿素b相反;湘烟7号与对照的叶绿素降解量差异不显著;湘烟7号的类胡萝卜素降解速率和降解量显著低于对照。可见,湘烟7号烘烤过程中烟叶失水和色素降解具有一定的独特性,需依据该品种烘烤特性制定适宜的烘烤工艺,以发挥其质量潜势。

| Abstract: | In order to explore the characteristics of water loss and pigment degradation during curing process of flue-cured tobacco of Xiangyan No.7, using Yunyan 87 as control (CK), the water loss characteristics of leaves and veins and the degradation characteristics of chlorophyll a, chlorophyll b, total chlorophyll and carotenoids were studied by electric-heated flue-curing barn. The results showed the water loss peak of Xiangyan No.7 was earlier than CK. The easy curing potential of middle and lower leaves were better than CK, while the upper leaf showed the opposite trend. In the early yellowing (24h), the degradation rate of chlorophyll a was significantly lower than that of CK, while the chlorophyll b showed a opposite trend. No significant difference in chlorophyll degradation existed between Xiangyan No.7 and CK. The carotenoid degradation rate and quantity of Xiangyan No.7 were significantly lower than CK. The characteristics of water loss and pigment degradation of leaves of Xiangyan No.7 during curing were unique. In order to develop the full quality potential of Xiangyan No.7, the curing technique should be formulated according to the curing characteristics of the variety. |
