Abstract

Xylem sap samples originating from cucumber plants treated with nickel ions in concentrations of 10-6, 3 · 10-6, 6 · 10-6 and 10-5 mol/dm3 in presence of Fe(III)-citrate or Fe(III)-EDTA were analyzed using total reflection X-ray fluorescence (TXRF) spectrometry. Independently of the choice of the iron(III) form, the amounts of the transported nickel in the xylem vessels increased near linearly (r > 0.98) by increasing the nickel concentration of the nutrient solutions. The lowest phytotoxic external nickel concentration for cucumber was to be considered 10-5 mol/dm3, which generally caused a decrease in the Fe and Zn transport in xylem, independently of the iron(III) compound used for the preparation of the nutrient solutions in identical concentration with that of nickel. However, the Mn-transport was stimulated.
