Nine Centaurea and three Viola species, predominately or exclusively found on serpentine in Greece were investigated, to examine their soil-tissue relations for Ni. Nickel content and distribution within the leaves showed that two species could be characterized as nickel hyperac- cumulators. Leaves from wild grown plants were examined and x-ray analyzed with a Scanning Electron Microscope equipped with an x-ray microanalysis system. 3830±312 μg and 1023±79 μg nickel g 1 of leaf dry mass was found in Centaurea thracica and Viola vourinensis correspondingly after atomic absorption spectroscopy. In both species the metal was accumulated in large epidermal cells. Centaurea thracica, a member of the Greek serpentine flora, is reported for the first time as a nickel hyperaccumulator. Viola vourinensis, a Greek serpentine endemic, though accumulating lower metal quantities than C. thracica, could be also characterized as nickel hyperaccumulator, since the threshold proposed for nickel hyperaccumulators is 1000 μg of the metal g 1 dry mass. © by PSP Volume 18 - No 5b. 2009. |
