The influence of the production system on the composition of phytochemicals in Prunus domestica L. fruit

Abstract

The objective of this study was to evaluate the influence of the production system (organic and integrated) on the composition of sugars, organic acids and phenolics of the fruits ‘Čačanska lepotica’ and ‘President’ plum (Prunus domestica L.). The analysis results show a significant influence of the cultivar on the composition of sugars, organic acids, phenolics and 3 subgroups of phenolics (hydroxycinnamic acids, anthocyanins and flavonols) and the specific response of the cultivar to the production system. In organic fruits, a higher content of hydroxycinnamic acids, cyanidin-3-glucoside, rutin and a lower content of cyanidin-3-rutinoside was found. Furthermore, the summer cultivar ‘Čačanska lepotica’ reacted to the organic production system with a higher content of sucrose, sorbitol, sum of sugars, shikimic acid, fumaric acid, sum of anthocyanins, individual flavonols and sum of flavonols. The production system influenced the cyanidin-3-glucoside/cyanidin-3-rutinoside ratio and the composition of sugars and flavonols in ‘Čačanska lepotica’.
