The effects were investigated of polluted soils containing heavy metals (collected in the vicinity of a copper works in Poland) used alone, and as mixtures containing various amounts of polluted soil mixed with sand or forest soil, on the growth, morphology and mycotrophy of roots of Scots pine seedlings. Significant differences in root system morphology (including the presence of mycorrhizas) and in height growth were found between seedlings in the different growing media, with some mixtures promoting growth (those with higher pH) and others (with lower pH) making the soil more toxic.
