Abstract

The aim of the present study was to compare trace element profiles and the differences in uptake and translocation of trace elements in plants from five populations (three from Greece and two from Serbia) belonging to three subspecies of Silene parnassica Boiss. & Sprun. growing on ophiolitic substrates. For comparison of the subspecies, bioconcentration and translocation factors were used, as well as Spearman’s rank correlation coefficients for concentrations of elements in root and shoot samples. Chemical characteristics of the soil samples (pH, organic C, P2O5, K2O, Ca, Fe, Mg, Mn, Ni, Zn, Cu, Cr, Co, Cd and Pb) and plant samples (P2O5, K2O, Ca, Fe, Mg, Mn, Ni, Zn, Cu, Cr, Co, Cd and Pb) were determined, as well as bioconcentration and translocation factors and correlation matrices. All the three subspecies acted as strong Ni accumulators, with equal concentrations of Ni in roots and shoots, the values being several times higher than 100 mg kg–1, exceeding concentrations of available Ni in the soil. Concentrations of Cu and Cr in the aboveground plant tissues in samples from three localities were several times higher than expected, even for plants growing on metalliferous soils, exceeding, by multiple times, the available concentrations in the soil samples.

Additional keywords: ophiolites, strong accumulators.
