Abstract: | Chlorophenols are precursors to more dangerous environmental toxicants, which are characterized by mutagenic and carcinogenic properties. The methods of bioassay on plant test objects to study the influence of different pollutants allow one to connect the mutagenicity and cytotoxicity of investigated substances. The genotoxic and cytotoxic effects of pentachlorophenol and trichlorophenol solutions on root meristem cells of the Welsh onion Allium fistulosum L. shoots have been studied. Doze-dependent inhibition of seed germination of Welsh onions as a consequence of the influence of pentachlorophenol and trichlorophenol solutions with different concentrations shows a significantly greater toxic effect of pentachlorophenol, dependending on the doze, on seed germination than trichlorophenol. |
