Abstract

In this study, a pot experiment was developed using a non-metallicolous ecotype of Silene vulgaris Garcke (Moench) exposed to 0, 60 and 120 µM Cd2+ for 13 days. The dose of 60 µM Cd2+ had little effect on the growth of S. vulgaris plants, whereas the highest dose produced a drastic reduction in biomass, and root and shoot elongation. The high internal Cd2+ concentration together with the high bioaccumulation coefficient in roots and the low translocation factor indicated that this ecotype could be a good candidate for the phytostabilisation of Cd2+-contaminated soils. In view of the widespread use of this plant in popular medicine and the cuisine of Mediterranean countries, the results obtained also suggest that caution needs to be taken concerning its origin since it could represent an additional source of Cd2+ in the human diet.
