Nutrient and heavy metal composition of berries and leaves of 'Regent' vine grafted on different rootstocks (dataset)

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 (53°40’ N, 14°46’ E). In the experiment, the nutrients Ca, Cu, Fe, K, Mg, Mn, N, P and Zn, and the heavy metals Cd and Pb were analysed. The data set contains soil composition (mg/kg), as well as composition of berries and leaves in mg/kg and g/kg of dry plant weight. The experimental treatments were arranged in a randomised complete block design. Each experimental unit was comprised of six vines. Each year of the study, soil and leaf samples were taken in a first/second decade of July at the phonological stage of berry set. The soil samples were collected using an Egner’s sampling stick from the humus level (0-50 cm). Leaves (blades and petioles) were collected from the central part of the one-year shoots, two-three leaves above second cluster. Grapes were collected on the first decade of October in successive seasons, with berry maturity ranging from an average of 19-20.5 °Brix.
