Influence of different concentrations of Pb-acetate on ornamental plants (Begonia tuberhibrida, Tagetes patula, Datura arborea) growth and development under conditions of experimental intoxication were studied. It has been proved that Pb-acetate has different impact on growth and development of these plants and that these differences are mostly dependant of plant species and concentration of Pb-acetate. Some plant species have shown rapid growth and development (Tagetes patula) with maximal concentrations of Pb-acetate (2x10E-2 M), while low concentrations of Pb-acetate has caused rapid growth and development to Datura arborea. However, Begonia tuberhibrida both concentrations of Pb-acetate had caused total inhibition of growth and development. It is possible that inhibition of biochemical-physiological processes preceded inhibition of growth and development. Inhibition biochemical-physiological processes comes much before any visible changes. Considering manifestation of such changes on these ornamental plants, species Tagetes patula can be classified as resilient to heavy metals and Begonia tuberhibrida as very sensitive plant species. Results acquired during research can be used for biomotoring.
