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

Pachnowska, Kamila; Ochmian, Ireneusz

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. A more detailed description of the sampling and analysis protocols, as well as the statistical analysis and discussion of the results is published in: Kamila Pachnowska and Ireneusz Ochmian (2018): Influence of rootstock on nutrients and heavy metals in leaves and berries of the vine cultivar ‘Regent’ grown in North-Western Poland,Journal of Applied Botany and Food Quality 91, 180 - 186, DOI:10.5073/JABFQ.2018.091.024
