Abstrakt
Phytoremediation technology is effective, non-invasive method used for removing of environmental contamination. The work compares the capability of toxic heavy metals Cd and Pb uptake by roots and aboveground tissues of micropropagated plantlets from selected hybrid aspen and rowan tree growing in trial plots in emission areas in the Ore Mountains. The two tested clones of rowan tree and hybrid aspen can accumulate high concentrations of toxic metals Cd (800 – 1,500 mg.kg-1) and Pb (5,000 – 13,000 mg.kg-1) in roots, in addition hybrid aspen accumulated more than 100 mg.kg-1 Cd in stem. Both clones are characterized by ability to grow well in the extreme site conditions.
