INFLUENCE OF IRON OF NANOPARTICLES ON INDUCTION OF OXIDATIVE DAMAGE IN TRITICUM VULGAREAnastasia Korotkova, Elena Sizova, Svyatoslav Lebedev.
This article is devoted to the study of the Influence of iron of nanoparticles on induction of oxidative damage in Triticum vulgare. Phenolic compounds are the most active in this group. In the process of oxidation they rebuilt in less reactive phenoxyl radicals and bi- and polyphenols, which interrupt oxidative transformations chain. Regarding the treated wheat, the spectra of the acetone fraction after treatment with 0.1 M iron NPs has no significant changes compared to the control. This study showed that iron NPs as transition metals have multiplex influence and contribute to development of ROS and to development of cytogenetic damages of wheat. There was an increase of the rate of ROS by 84% (p<0.01) and 83% (p<0.05) in case of the maximum concentration of iron NPs compared to background fluorescence of the coloring agent. And when influenced by a minimum concentration of iron NPs (0.025 M) there was observed more uniform distribution of DCF fluorescence over the entire volume of the apex value of which was less than the control even by 7% (p<0.05). Primary effect is explained by an increase in fluorescence of DCF and oxidation of phenolic fraction of molecules of wheat.
