Влияние концентрации наночастиц ZnO на биометрические параметры проростков пшеницы

Abstract

Production and application of nanopowders intensively develop and cause nanoparticles' release into the environment. Because of their high solubility, small size, high reactive properties and migration activity, nanoparticles can be both dangerous and useful for the plants. In our work, we have examined the effect of concentration of ZnO nanoparticles on biometric parameters of wheat seedlings. It has been experimentally shown that the addition of 10…1000 mgL-1 of nanoparticles causes 27,2...50,3% growth of root length, 10...40% increase of the germination, 22,8...49,8% decrease of root index and 9...117,3% growth in biomass rate, while >1000 mgL-1 concentration there is no evident effect of nanoparticles on the root development in comparison with control.
