Zemědělské plodiny využitelné pro hyperakumulaci těžkých kovů a fytoremediace Crops as metal-hyperaccumulators and their using for phytoremediation
An ideal plant for phytoremediation should meet several criteria:
1. to grow rapidly and to produce large quantities of biomass,
2. to deeply root and to have an easily harvested shoots,
3. to accumulate high concentrations of contaminants in the shoots.
Presently known hyperaccumulators of metals, in other words plants capable of over-accumulation metals in their tissues,
meet the third criterion of an ideal plant for phytoremediation. In contrast, crops meet the first two criteria of an ideal plant
for phytoremediation. In this paper we discuss the advantages and potential use of agricultural crops in phytoremediation with
a view to further development towards increasing their accumulation properties.
Key words: hyperaccumulator, crop, phytoextraction, heavy metal.
