ABSTRACT
The effect of lead ions of the concentrations within the range of 15–1000 mg∙dm-3 on the physiological reaction of common osier var. Jorr was examined. The content of assimilation pigments, the rate the CO2 assimilation, transpiration, the indices of relative water content and the deficit of water saturation and the content of lead in the nutrient solution. The studied physiological parameters in common osier var. Jorr were differentiated by the rate of lead ions in the nutrient solution. The Jorr variety of common osier was characterised by good values of the determined physiological parameters under stressful conditions at a large accumulation of lead. This suggests that it shows quite a high tolerance to the stress caused by contamination of the subsoil with lead.
