Abstract: A plant’s ability to survive in a stressful environment is correlated with its nutritional status, which can be affected by cadmium (Cd) uptake. The present study evaluated the influence of Cd on the concentrations and distributions of nutrients in the roots and shoots of the Cd-hyperaccumulator Pfaffia glomerata (Sprengel) Pedersen. Plantlets were cultivated in nutrient solutions containing increasing Cd concentrations during 20 days under greenhouse conditions, and the concentrations of Cd and essential macro- (N, P, K, Ca, Mg and S) and micro- (Zn, Fe, Mn, Cu) elements in the roots and shoots were subsequently determined. Cd did not affect the plant biomass production. Cd accumulation was found to be higher in roots than in shoots, and influenced the distribution of macro and micro elements in those plants. Despite the high phytotoxicity of this element, our results indicated the existence of Cd-tolerance mechanisms in both nutrient uptake and distribution processes that enabled these plants to survive in Cd-contaminated sites.
