Segregation of Apple Cultivars Based on Phytochemical Properties Following Calcium Chloride Foliar Application
摘要
This study examined the impact of calcium chloride (Stopit) treatment on three apple cultivars—‘Granny Smith,’ ‘Golden Delicious Reinders,’ and ‘Red Chief’—during the 2018, 2019, and 2020 growing seasons. We evaluated the effects of cold storage on total phenolic content (TPC), antioxidant capacity (AC), and anthocyanin content (TAC) in both whole fruits and peels. The results show that ‘Granny Smith’ had the highest TPC and AC in whole fruits, while ‘Red Chief’ had the lowest AC. The peel exhibited higher TPC and AC than whole fruits, with ‘Red Chief’ having the highest TPC and ‘Golden Delicious Reinders’ the lowest. Cold storage affected these properties, with the highest AC found in the peel of ‘Granny Smith’ after 60 days of storage. The findings highlight the importance of cultivar selection and postharvest treatments in enhancing apple nutritional quality, providing valuable insights for both consumers and producers.
