Fig. 7From: Identification of physiological and metabolic networks involved in postharvest browning of cigar tobacco leavesMetabolic pathways of the main metabolites at different periods of air-curing. The bars show from left to right the metabolite content in WrC0, WrC6, WrC12, WrC20, and WrC26. The values represented by the colors are the quantitative results of the metabolites obtained based on the total peak area quantification and normalizationBack to article page
