摘要: 为探讨全生育期覆膜对高海拔多雨烟区烤烟品质及香气代谢的影响,在贵州省黔西南州兴义市开展田间试验,设置常规揭膜(移栽后40 d,CK)和全生育期覆膜(FM)2种处理。分析C3F烟叶的主要化学成分、感官品质及代谢组学特征。结果表明,与CK相比,FM显著提高了烟叶中还原糖、烟碱、钾和总氮含量,极显著降低了淀粉积累,整体化学成分更趋协调;感官评吸显示,FM的香气量、余味等指标显著改善,感官总分较CK提高了6.45%;代谢组学分析共鉴定出178种显著差异代谢物,其中,(E,E)-2,4-庚二烯醛、苯乙醇、苯甲醛、柠檬醛、(E)-3,7-二甲基-2,6-辛二醛等关键香气物质在FM处理中显著富集;进一步 Mantel 分析表明,这些关键代谢物的差异变化与香气量、余味等感官指标的差异模式存在显著对应关系(P<0.05)。综上,全生育期覆膜可通过调控关键香气代谢物谱系并促进其积累,提升多雨烟区烤烟的香气品质与感官风格。

Abstract: To investigate the effects of full-period plastic mulching on the quality and aroma metabolism of flue-cured tobacco in high-altitude and rainy tobacco-growing areas, a field experiment was conducted in Xingyi City, Qianxinan Prefecture, Guizhou Province. Two treatments were set up: Conventional film removal at 40 days after transplanting (CK) and full-period plastic mulching (FM). The main chemical components, sensory quality and metabolomic characteristics of C3F tobacco leaves were analyzed. The results showed that compared with CK, FM significantly increased the contents of reducing sugars, nicotine, potassium and total nitrogen in tobacco leaves, and highly significantly reduced starch accumulation, leading to more coordinated overall chemical composition. Sensory smoking evaluation indicated that FM significantly improved aroma quantity, aftertaste and other indexes, with the total sensory score increasing by 6.45% compared with CK. A total of 178 significantly differential metabolites were identified by metabolomic analysis, among which key aroma substances such as trans,trans-2,4-heptadienal, phenethyl alcohol, benzaldehyde, citral and (E)-3,7-dimethyl-2,6-octadienal were significantly enriched under FM treatment. Further Mantel analysis revealed that the differential changes of these key metabolites were significantly correlated with the variation patterns of sensory indexes including aroma quantity and aftertaste(P<0.05). In conclusion, full-period plastic mulching improved the aroma quality and sensory style of flue-cured tobacco in rainy tobacco areas by regulating and promoting the accumulation of key aroma metabolite profiles.
