Study of accumulation of cadmium ion by energy crops
 Berkyová, Petra ; Soudek, Petr (advisor) ; Petrová, Šárka (referee)
Cadmium is heavy metal toxic for plants and animals and environmental contaminant which must be removed from natural environment. In recent years a new method phytoremediation is getting more attention. This method uses plants called hyperaccumulators for extraction of heavy metals from soils. Hyperaccumulators have, however, after accumulation of heavy metals no other use. Therefore new possibilities are discussed in last few years. Energy plants, in this thesis sorghum and malva, could be used for accumulation of heavy metals from soils and after that these plants could be used as energy source. This thesis wants to find out if sorgum and malva are able to grow in cadmium contaminated environment and if these plants will accumulate cadmium. It also compares different cultivars of sorghum in toxicity tests and compares ability of these cultivars to grow in cadmium contaminated environment and to accumulate this heavy metal. Further it focuses on affection of uptake of kadmium ions by sorhum in presence of glutathione or ethylenediaminetetraacetic acid.
