THE STUDY OF IONS, NANO- AND MICRO-SIZED CU AND FE PARTICLES BIOSAFETY IN TRITICUM AESTIVUM SEEDS GERMINATION TEST ^{[№ 12 ' 2011]}
In Triticum aestivum seeds germination test the influence of equimolar concentrations of ions, nano- and micro-sized Cu and Fe particles has been investigated. The EC50 phytotoxicity level is much more exhibited on copper compared to the iron and dramatically increased at row line "microparticles > nanoparticles > ions". The most expressed reaction of wheat sprouts root system to influence of investigated toxicants is established.
