Przydatność wybranych organów ‘Robinia pseudoacacia’ do celów bioindykacyjnych

Abstract

The aim of this study was to determine the suitability of chosen organs of Robinia pseudoacacia as bioindicators. Content of selected elements in leaves, shoots, seeds, pods and bark of R. pseudoacacia from the area of three cities of Silesia province: Katowice, Chorzow and Siemianowice Slaskie was estimated. In each of the cities five sampling points were selected. Localizations were grouped in three categories differing in terms of the level of pollution (traffic, industrial plants). Statistically significant differences between pollution level of segregated groups in investigated localizations were found. On the basis of PCA and cluster analysis for individual organs sampling points were divided into groups depending on concentration of investigated elements in tissues of R. pseudoacacia. Conducted studies suggest that the organ best suitable for bioindication are leaves of R. pseudoacacia.
