From: Transcriptome profiling reveals the roles of pigment mechanisms in postharvest broccoli yellowing

a−c The sensory images obtained during broccoli yellowing. d−i Fluorescence images corresponding to the Fv/Fm (d−f) and NPQ (g−i) values. The images in (d−i) were normalized to a false color bar. Determination of the Fv/Fm ratio was carried out on dark-adapted broccoli for 15 min, while NPQ analysis was conducted at the optimum light saturation intensity
