Accumulation kinetics of the proanthocyanidins catechin, epicatechin, and epigallocatechin during V. vinifera 'Cabernet Sauvignon' (blue dashed line) and V. aestivalis 'Norton' (red solid line) berry skin development. Cabernet Sauvignon berry skin were collected at 49, 59 (véraison, blue arrow), 71, 90 and 112 days after bloom (DAB), and Norton berry skin at 66, 71 (véraison, red arrow), 85, 99 and 127 DAB. Bars indicate standard error of three biological replicates per sample.
