Phytoextraction of Risk Elements by Willow and Poplar Trees

Popis výsledku v původním jazyce

To characterize the phytoextraction efficiency of two clones of willow trees (Salix x smithiana Willd., Salix rubens) and two clones of poplar trees (Populus nigra x maximowiczii, Populus nigra Wolterson) were planted in contaminated soil (0.4-2.0mg Cd.kg(-1), 78-313mg Zn.kg(-1), 21.3-118mg Cu.kg(-1)). Field experiment was carried out in Czech Republic. The study investigated their ability to accumulate heavy metals (Cd, Zn, and Cu) in harvestable plant parts. The poplars produced higher amount of biomass than willows. Both Salix clones accumulated higher amount of Cd, Zn and Cu in their biomass (maximum 6.8mg Cd.kg(-1), 909mg Zn.kg(-1), and 17.7mg Cu.kg(-1)) compared to Populus clones (maximum 2.06mg Cd.kg(-1), 463mg Zn.kg(-1), and 11.8mg Cu.kg(-1)). There were no significant differences between clones of individual species. BCs for Cd and Zn were greater than 1 (the highest in willow leaves). BCs values of Cu were very low. These results indicate that Salix is more suitable plant for phytoextraction of Cd and Zn than Populus. The Cu phytoextraction potential of Salix and Populus trees was not confirmed in this experiment due to low soil availability of this element.
