| Summary: | Remediation methods allow the removal of metals from contaminated soil, and phytoremediation a technology for cleaning contaminated soil and waste material by plants, is becoming increasingly used. Brassica napus L., as one of the main oilcrops and high-biomass producing species, is becoming more and more interesting for the use in phytoextraction as it is proved to be tolerant to higher concentrations of heavy metals. The aim of this study was to examine the specific responses of three commercial winter rapeseed varieties, Banaćanka, Slavica and Kata, to the increased concentrations of lead in vitro. Significant reduction in root length of plants treated with lead was observed only in the variety Slavica, indicating susceptibility of this variety to the increased concentrations of this heavy metal. As in variety Kata a significant reduction in the length of the above-ground part due to the treatment with lead was detected, it could be concluded that the variety Banaćanka is the most tolerant to the applied concentrations of lead since there were no significant changes in the growth and biomass accumulation in all treatments except one, and could be recommended for further use in phytoremediation studies.
