Abstract

The intraspecific tolerance of some herbs to the effect of different copper concentrations was studied. Seeds of the Agrostis stolonifera L., Melandrium rubrum L. and Rumex acetosela L. were collected from the region with contaminated (tolerant population) and not-contaminated (sensitive population) soils. Seedlings of the above-mentioned herbs were treated with differentCu concentrations and cultivated under laboratory conditions. Genotype frequency was estimated on the basis of the index of tolerance. Using this methodical approach a survey of the frequency of individuals in different stage of tolerance was determined. In the plants of tolerant population the genotype frequency of the individuals with the high values of the index of tolerance showed that the genetical structure was changed in favour of this population. The use of the seeds of F-1 generation confirmed that tolerance is not only a dominant but also an inheritable feature for the further generation. Therefore it could be concluded that the seeds from the studied plants of the tolerant population are suitable for phytoremediation as an effective application in the decontamination of metal-polluted soils.
