Opis:: 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.

Opis:: The influence of copper salt, in a concentration range of 50–150 mg·dm−3, on the physiological response of basket willow was studied on Tora variety, which were grown in hydroponics. Content of assimilation pigments, relative water content (RWC), water saturation deficit (WSD), intensity of assimilation and transpiration, stomatal conductance, photosynthetic rate of water use efficiency (WUE) and instantaneous photosynthetic rate of water use (WUEI) were determined in leaves. It was observed that the decrease in the concentration of tested physiological parameters correlated with the increase in copper salt doses in the medium. The assimilation and transpiration of basket willow were significantly limited by stomata. The addition of copper salt to the medium increased WSD in leaves of the basket willow. The obtained results of the studied physiological parameters may prove useful for the assessment of resistance of the studied willow cultivar to stress caused by increased copper ion content in medium and its applicability in reclamation of areas degraded by humans.
