Description
Summary:In this study, thirteen Japanese plum cultivars (Prunus salicina Lindl.) grown under conven tional and organic conditions were compared to evaluate the influence of the culture system on bioactive compounds. Their organic acids content (malic, citric, tartaric, succinic, shiki mic, ascorbic and fumaric acid), total polyphenols, total anthocyanins, total carotenoids and antioxidant capacity (FRAP, ABTS) were evaluated. The study was performed during two consecutive seasons (2012 and 2013) in two experimental orchards located at the IFAPA centre Las Torres-Tomejil (Seville, SW Spain). The culture system affected all the studied parameters except for total carotenoid content. The organic plums had significantly higher polyphenol and anthocyanin concentrations and a greater antioxidant capacity. Addition ally, significant differences between cultivars were also found. ‘Showtime’ and ‘Friar’ were the cultivars with the highest polyphenol concentration and antioxidant capacity. ‘Black Amber’ had the highest anthocyanin content and ‘Larry Ann’ and ‘Songold’ the highest carotenoid content. ‘Sapphire’ and ‘Black amber’ were the cultivars with the highest concen tration of ascorbic acid. Our results showed a strong year effect. In conclusion, organic man agement had an impact on the production of phytochemical compounds in plums.
