Abstract: | We have investigated the effect of cultivation systems and fruit post-harvest management on the antioxidant properties of
apricot fruits. Trees of five cultivars ‘Tyrinthos’, ‘Cafona’, ‘Bella d’Italia’, ‘Vitillo’ and ‘Pellecchiella’ were cultivated
under integrated and organic systems. Fruits were collected at full maturity stage and analyzed either immediately or after
storage at 4±0.5 °C and 85% of relative humidity for seven and 14 days. The main pomological traits (weight, colour, flesh
firmness, total soluble sugars, titratable acidity) and antioxidant properties were analyzed. The total antioxidant capacity
(TAC by TEAC method), total phenols content (TP by Folin-Ciocalteu method) and carotenoid content by HPLC-DAD were monitored.
Cultivar characterization by principal component analysis (PCA) indicated a large variability on pomological and antioxidant
properties of apricot fruits. ‘Bella d’Italia’ showed better TAC and TP values compared to the other cultivars. ANOVA interactions
between cultivar and cultivation system (organic/integrated) were found for the antioxidant properties. These interactions
may help to select a set of genotypes with better performances under organic system, which in our study might be indicated
in ‘Cafona’ and ‘Bella d’Italia’. |
