摘要: 为明确不同烤烟品种质体色素含量在不同香型烟叶产区的差异,采用GC/MS法分别检测了种植在典型浓香型、中间香型、清香型烟叶产区K326、云烟87和湘烟3号第9-12叶位烟叶的质体色素降解产物。结果表明:检测到的绝大多数质体色素降解产物含量在不同品种间存在显著差异,且云烟87的叶黄素和β胡萝卜素类降解产物含量显著高于K326和湘烟3号;检测到的全部的质体色素降解产物在不同香型烟叶产区间存在显著差异,叶黄素、β胡萝卜素和无环类胡萝卜素降解产物总含量和质体色素降解产物中的巨豆三烯酮A、巨豆三烯酮B、巨豆三烯酮C、巨豆三烯酮D、β-紫罗兰酮、脱氢二氢-β-紫罗兰酮6种致香成分含量在两个浓香型烟叶产区无显著差异,但一致地显著高于中间香型和清香型烟叶产区,且按浓香型、中间香型、清香型烟叶产区的顺序依次递减。烟叶质体色素降解产物含量在不同品种、不同香型烟叶产区间差异的存在,揭示了不同生态产区烟叶香型特色形成的物质基础,对彰显不同烟叶香型烟草品种的选育具有重要指导意义。

Abstract: To determine the variation of plastid pigment degradation products in flue-cured tobacco cultivars in different production areas, the plastid degradation products in the 9th-12th tobacco leaves were analyzed by GC/MS with‘K326’,‘Yunyan 87’and‘Xiangyan 3’planted in typical flavor, middle flavor and fragrant tobacco-producing areas, respectively. The results showed that most plastid degradation products detected in tobacco leaves were significantly different among the three cultivars, and the degradation products of lutein and β-carotenoid were higher in‘Yunyan 87’than those in‘K326’and‘Xiangyan 3’. All of the detected plastid pigment degradation products in leaves were significantly different among the three types of tobacco-producing areas, the three aroma components containing megastigmatrienone A, B and D, which were remarkably higher in typical flavor tobacco-producing area than in middle flavor and fragrant tobacco-producing areas, were sequentially decreased from typical flavor obacco- producing area to middle flavor and fragrant tobaccoproducing areas. The difference of plastid pigment degradation products among cultivars and tobacco producing areas reveals the material basis of aroma formation in tobacco leaves from different ecological planting areas, and is important to developing tobacco cultivars with different flavors.
