Influence of zinc nanoparticles on the development of sprouts of Avena sativa and Pisum sativum plants

Abstract

The research aim is to study the effect of zinc nanoparticles on morphological parameters of sprouts of monocotyledonous and dicotyledonous plants (Avena sativa, Pisum sativum) during its accumulation in the environment. In laboratorial conditions of the experiment, it was found peculiar features of various concentrations of nanoparticles. It was specified the multidirectional effect of zinc macro- and nanoparticles onto growth rate, green weight of both aboveground and underground parts, as well as species related effect. Authors of the article identified concentrations of macro- and nanoparticles trigger permanent biological response on the experimental plants. A stable stimulating effect of zinc nanoparticles on all indicators of growth and development of pea seedlings at the concentration of 20 mg per 100 ml was revealed. A similar effect was found in oat seedlings which were exposed to zinc nanoparticles at the concentration of 5 mg per 100 ml. The effects of zinc macro- and nano-particles on plants were manifested differently.
