Salinity effects on colour and health traits in the pomegranate (Punica granatum L.) fruit peel

Irrigation water salinity effects on colour and health ingredients in the pomegranate peel were studied in two accessions, ‘Wonderful’ and ‘SP-2’, grown under a wide range of salinities, 1.2 to 9 dS m–1. Ripe fruit peels were analysed for phenolics and anthocyanins composition, and antioxidative capacity. Total phenolics concentration and antioxidative capacity were determined by the Folin-Ciocalteau and FRAP assays, respectively. Phenolics and anthocyanins composition was analysed by RP-HPLC. Increased salinity enhanced considerably the overall accumulation of phenolics and anthocyanins, and the antioxidative capacity in both cultivars; the magnitude of the effects was accession dependent. Mono- and di-glucosides of cyanidins, pelargonidins, and delphinidines were detected at proportions that varied with accession and salinity. Increased concentrations of gallotannins, flavonols and ellagic acid derivatives in ‘Wonderful’, and punicalagins, flavonols and ellagic acid derivatives in ‘SP-2’ accompanied ele...

期刊介绍： Technology is an increasingly crucial input in the industrialisation and development of nations and communities, particularly in the current era of globalisation, trade liberalisation and emphasis on competitiveness. The shared technologies and innovations of today are giving birth to the radically different agrifood industries and communities of tomorrow. There is mounting evidence that investments in postharvest research and infrastructure yield high rates of return that are comparable and often higher than investments in on-farm production alone.
