| Abstract | This study evaluates the extent of accumulation of Cd, Pb and Zn in Matricaria recutita and the effect of heavy metals uptake on plant biomass, antioxidant potential and essential oil yield and quality. Matricaria recutita L plants were grown as a pot experiment on soil collected from the vicinities (1 km) of a Non-Ferrous Metals Combine and on non-contaminated control soil. If we take into account the high content of Cd, Pb and Zn in the plant organs only small plant growth retention occurred in treated plants. Therefore, this plant species exhibited tolerance to high levels of Cd, Pb and Zn in the soils. Accumulation of low molecular antioxidants such as ascorbate, glutathione and flavonoids in the above ground parts of treated plants was observed. Enzymatic antioxidant defence was activated in the plants grown on contaminated soil, mainly on the account of ascorbate peroxidase in the above ground parts, glutathione peroxidase and quaiacol peroxidase in the leaves and dehydroascorbate reductase and glutathione-S-transferase in the flowers. Despite the accumulation of Cd, Pb and Zn in the plant organs, essential oil yield and quality did not change significantly. |
