Experimental data to manuscript by Drzewiecka et al. (Salix x fragilis; drought, Zn, Cu)

Biometric data, RWC, content of elements, content of metabolites (phenolics, organic acids) in willow Salix x fragilis organs. The data set contains the experimental numeric data on the parameters of Salix x fragilis plants (male and female specimens) cultivated hydroponically under greenhouse conditions. Plants were treated with zinc or copper nitrates and subjected to the action of sorbitol in order to simulate drought conditions. Isolated and combined treatments were performed. After treatment several plant parameters were investigated, such as: plant biomass, relative water content, Zn, Cu content, content of mineral nutrients, profiling of metabolites in willow organs (phenolics, organic acids). Data will be updated.
