The influence of year and location on polyphenols and anthocyanins content in sour cherry cultivars
Sour cherry is an important fruit in Croatian orchards because its products are very popular within food industry. The products, such as jams, juice concentrates, frozen sour cherries, alcoholic drinks and other, are rich with antioxidants. The aim of this study was to determine how different locations and years influence polyphenols and anthocyanins content in fruits of different sour cherry cultivars. Fruits of six sour cherry genotypes were harvested in two locations (Osijek and Zadar) over three consecutive but climate different years (2009, 2010 and 2011). The content of polyphenols and anthocyanins was determined spectrophotometrically. Analysis of variance showed that year significantly influenced polyphenols and anthocyanins content. 2010 was the best year with 932.32 mg of gallic acid/100g fresh weight of polyphenols and 483.10 mg of cyanidin-3-glucoside/100g of fresh weight of anthocyanins in average. The results of one-way ANOVA indicated that location did not influence the accumulation of polyphenols and anthocyanins in sour cherry fruits. According to content of polyphenols and anthocyanins, cvs. Maraska and Rexelle appear to be the best source of bioactive compounds over the investigated genotypes.
