Developmental Changes in Phenolic Composition and Condensed Tannin Structure in the Skins of Three Table Grape Cultivars: ‘Rosetta’, ‘Shooting Star’, and ‘Hongju Seedless’
This study investigated developmental changes in phenolic compounds and condensed tannin structure in the berry skins of three table grape cultivars, ‘Rosetta’ (RT), ‘Shooting Star’ (SS), and ‘Hongju Seedless’ (HS), from flowering to harvest. Spectrophotometric analyses were used to quantify total phenolic, proanthocya...
