Fruits of ribes, rubus, vaccinium and prunus genus. Metal contents and genome

The production of fruits of genus Ribes, Rubus, Vaccinium and Prunus is particularly important in mountain communities. The contents of macro- and microelements in fruits from different cultivars of blueberry (Vaccinium corimbosus L.), red currant (Ribes rubrum L.), raspberry (Rubus idaeus L.) and cherry (Prunus avium L.) were determined. The anthocyanin and total polyphenol contents of the fruits were also determined. The results were analyzed with statistical methods. By using the one-way analysis of variance (ANOVA) the various genera of the fruits were found to be differentiable on the basis of their metal contents. Multivariate statistical analysis, performed using principal component analysis (PCA), confirms that the different fruits can also be well discriminated by their contents of metals, total anthocyanins, and polyphenols.
