Metabolic characterization and antioxidant activity in sweet cherry (Prunus avium L.) Campania accessions Metabolic characterization of sweet cherry accessions

摘要

The failure of the antioxidant scavenging system in advanced ripening stages, causing oxidative stress, is one of the most important factor of fruit decay. Production of rich antioxidant fruit could represent a way to delay fruit senescence and preserve its characteristics. We investigated the antioxidant metabolites (ascorbate, glutathione, tocopherols, and polyphenols) and enzymes (ascorbic peroxidases, peroxidases and polyphenol oxidases) involved in the antioxidant response in forty-three accessions of sweet cherry fruits from Campania region.
