Popis: In a model pot experiment, the influence of elevated levels of cadmium and lead in soils on rapeseed (Brassica napus L.) growth, development, biomass (g DM pot-1), cationic ratios (Cd2+:Ca2+, Cd2+:Mg2+, Pb2+:Ca2+, Pb2+:Mg2+) and tolerance index Ti, has been examined. The tested soils were: two organic soils (acidic and neutral) and a mineral one with pH differentiated into neutral and acidic. The metals were spiked into soils in doses of 10 mg Cd kg –1 DM and 100 mg Pb kg –1 DM of soil. Under the applied doses, the sensitivity of rapeseed to Cd was higher than to Pb. The application of Cd caused visible symptoms of chlorosis on plant leaves and a statistically significant ( p organic neutral > mineral acidic > organic acidic. The Cd added to soil increased the Cd 2+
