IMPACT OF STRESS FACTORS ON THE GENERATION OF NANOPARTICLES IN THE BIOLOGICAL STRUCTURES

Abstract

This article has been devoted to the research of the formation of iron oxide nanoparticles in some
of the plant and soil samples and the impact of stress factors in this event. Studied element analysis of
leaves plants, which widespread in the territory of Lankaran - lemon, orange, magnolia, kiwi and feijoa.
Taken EPR spectra of these plant samples and taken from they are grown soil samples. This specters
prove that the magnetic nanoparticles is formed in plants and at the same time they some extent
accumulation in plants from the soil. In addition in this article was studied the formation of magnetic
nanoparticles in chloroplasts, as well as wheat and maize plantlets and impact of various factors
(various concentrations of FeCl2, FeCl3 and of NaCl) to the formation of nanoparticles. Has been
known, that a certain dose of stress factor that stimulates the formation of nanoparticles in plants.
