Pomegranate fruit as a medicinal fruit has an important role in maintaining human health due to its high antioxidant content. Biostimulants are natural and pro-ecological compounds that increase the quality of the product by stimulating plant processes. The aim of this study was to investigate the effect of foliar application of cinnamic acid (0, 1, 5, and 10 mM) in three stages (20, 40, and 60 days before harvest) on improving the nutritional quality of pomegranate during the years 2019 and 2020. This research was carried out in one of the commercial pomegranate orchards in Neyriz city, Fars province, on 15-year-old pomegranate trees of Rabab cultivar as a randomized complete block design with three replications. Foliar application with cinnamic acid had a significant effect on the quality traits and antioxidant system of pomegranate fruits. The results indicated that cinnamic acid treatment increased the amount of Total Soluble Solids (TSS), Titratable Acidity (TA), and vitamin C. Based on the results obtained from this research, cinnamic acid increased PAL enzyme activity, which led to a significant increase in the antioxidant characteristics such as total phenol, total flavonoid, and total anthocyanin compared to the control. Therefore, the use of 10 mM cinnamic acid is suggested to improve the antioxidant system and increase the nutritional quality of pomegranate fruit.
