Abstrakt

The pot experiment was conducted in laboratory conditions. The soil used in experiment was loamy sand with 1.2% of organic carbon. To individual soil samples the following solutions were added 2.5 mM Pb(NO3)2 (207 mg Pb+2), 30 mM NaF (570.0 F– ), 0.05 mM H2SeO3 (3,95 Se4+), aqueous emulsion of Izoturon 500 SC herbicide in an amount of 6.5 mm3 · kg–1 soil. The aim of this study was to determine the influence of chosen pollutants on biometric parameters and SOD activity in three winter rye cultivars. Substances applied to the soil significantly reduced growth, fresh weight and superoxide dismutase activity in three winter rye cultivars planted in contaminated soil in comparison with control plants. Rye cultivars were characterized by different tolerance to chosen substances. It was found that cultivar ‘Chrobre’ was more sensitive to introduced pollutants than ‘Skat’ and ‘Dańkowskie Diamant’.
