The aim of this study was to evaluate nutrient contents and heavy metals of the leaves and berries of vine cultivar ‘Regent’ grafted on different rootstocks (‘Couderc 161-49’, ‘Sori’, ‘Kober 125AA’, ‘Börner’ and ‘Kober 5BB’) in comparison to control (‘Regent’ root; own-rooted vines). Leaf and berry samples were collected in three consecutive years (2013-2015) at the research station of West Pomeranian University of Technology Szczecin in Poland. In the experiment, Ca, Cu, Fe, K, Mg, Mn, N, P and Zn were analysed among mineral nutrients, whereas Cd and Pb were analysed among heavy metals. A substantial influence of tested rootstocks on analysed element contents in leaves and berries has been proven. All tested rootstocks enabled a higher concentration of Ca and Mg in leaves in comparison to ‘Regent’ root. The greatest concentrations of Ca, K and N were found in leaves and berries under ‘Sori’ rootstock. As the only rootstock, ‘Couderc 161-49’ was characterised by a higher level of iron in samples in relation to own-rooted vines. The ‘Börner’ rootstock was the most effective in inhibition of heavy metals uptake.
