Abstract
Rapeseed plants were exposed to seven different concentrations (0.5, 1, 3, 6, 12, 24, 60 μmol · dm) of CuSO4·5H2O for 7 days. Within concentration range 0.5-3 μmol · dm a significant increase of biomass (both plant organs) was observed. Decrease of biomass was notable after application of concentrations higher than 6 μmol · dm. Considerable drop in content of chlorophylls as well as carotenoids was observed after application of 6 μmol · dm Cu(II). Decline of protein content in leaves of plants was observed in concentration range 6-60 μmol · dm. Lipid peroxidation expressed as a content of malondialdehyde in leaves was strong within concentration range 6-60 μmol · dm Cu(II). Bioaccumulation factor values of roots were higher then those of shoots in the whole concentration range (0.5-60 μmol · dm Cu). The portion of Cu allocated in shoots related to the total Cu amount accumulated by plant ranged from 27.6% (0.5 μmol · dm) to 8.4% (60 μmol · dm).
