Determination of berry veraison (a, b) and changes in melatonin content (c) in ‘Merlot’ berries under 50 μM melatonin treatment. Berry veraison was indicated by berry coloring, increases in total soluble solids and anthocyanins and decreases in titratable acid. Values represent the means ± SD of three replicates. * Significant difference, P < 0.05; ** highly significant difference, P < 0.01
