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.

W badaniach wykorzystano cztery gatunki roślin uprawnych: żyto i pszenicę – rośliny jednoliścienne z rodziny traw oraz łubin i koniczynę – rośliny dwuliścienne z rodziny bobowatych, które pochodziły z upraw hydroponicznych. Po czterech tygodniach od wschodów obniżono pH pożywki (pH = 4,5) i dodano jony glinu w stężeniach 5, 10, 20, 40, i 100 mg·dm–3 pożywki jako AlCl3, a w drugim wariancie dodano jony miedzi w stężeniach 20, 50, 100 mg·dm–3 pożywki jako CuCl2. Stwierdzono, że badane gatunki, zwłaszcza żyto, lepiej tolerowały skażenie środowiska glinem niż miedzią, pomimo znacznie wyższej akumulacji glinu w swoich tkankach. Najniższą odporność na miedź i glin odnotowano u koniczyny a następnie u pszenicy. Generalnie gatunki roślin (żyto i łubin), które z reguły lepiej tolerują kwaśny odczyn podłoża, wykazały również lepszą odporność na skażenie środowiska glinem i miedzią, o czym świadczą wysokie indeksy tolerancji dla tych roślin. Oba badane pierwiastki akumulowane były przede wszystkim w korzeniach roślin, przy czym indeks translokacji dla glinu był znacznie niższy niż dla miedzi.
