Thlaspi caerulescens, a metallophyte that is able to accumulate up to 4% zinc (Zn) in leaf dry matter, has attracted much attention for its possible use in phytoremediation of metal contaminated soils. In the present study, the influence of Zn supply on mineral nutrition in T. caerulescens was investigated, in order to establish the extent to which growth stimulation by high Zn supply is related to changes in the levels of other essential nutrients. The plants were exposed to nutrient solutions containing 1.5, 100, 500, 750, 1000, or 1500 μM Zn. Zinc supply significantly influenced root and shoot concentrations of essential nutrients, but excepting Zn, the concentrations stayed within the range considered adequate for optimum growth in Brassicaceae crops. Best performance was achieved with the supply of 500 μM Zn. Growth stimulation by this treatment was accompanied by increased translocation of iron (Fe) from root to shoot and a significant correlation between shoot dry weight and Fe concentrations in shoots was found.
