| Abstract : | Four crop species were used in the study: rye and wheat – monocots from the plant family of grasses, and lupines and clover – dicotyledonous plants from the family Fabaceae grown in hydroponics cultivation. Four weeks after the emergence the pH of the medium (pH = 4.5) was lowered and aluminium ions, at concentrations of 5, 10, 20, 40 and 100 mg dm–3 medium, were added in the form of AlCl3. In an alternative experiment, copper ions were added at concentrations of 20, 50 and 100 mg dm–3 medium as CuCl2. It turned out that the tested species (in particular rye) tolerated environmental pollution with aluminium better than with copper, despite the fact that the accumulation of aluminium in their tissues was much higher. The lowest resistance against copper and aluminium was noted for clover and wheat. Generally, the species (rye and lupine) which better tolerate the acidic medium also showed better resistance against environmental contamination with aluminium and copper. High indexes of tolerance for those plants are evidence for this thesis. Both analysed elements were mostly accumulated in the roots of plants and the translocation index for aluminium was much lower than that for copper. |
