Response of Phaseolus vulgaris plants to cadmium with different accompanying anions exposure

Popis výsledku v původním jazyce

In this pot experiment Phaseolus vulgaris var. nana were grown in model soils contaminated with cadmium. We used two concentrations of Cd (2 and 20 mg kg-1) in pairs with the same anion (NO3-, Cl-, SO42-). The highest content of cadmium was found in the roots in all variants and declined in the order: roots > stems > leaves > pods. It was different in both variants contaminated with Cd(NO3)2. Here pods accumulated more Cd than leaves. In all variants with Cd contamination, the production of biomass was stimulated. The most noticeable symptoms of toxicity showed a variation with CdCl2. Cl- has probably a tendency to move Cd from the solid soil, which increases its bioavailability. We found a very positive and strong correlation (r= 0.9516) between the transpiration rate and Cd accumulation in plants. We assume that plants prevent against high doses of Cd.
