Abstract
The purpose was to conduct field tests of the most active metal nanoparticles of iron, cobalt and copper to realize the maximum accumulation of polysaccharides in plants; to develop a method for obtaining and studying the structure of polysaccharides obtained from plants treated before sowing with metal nanoparticles; to study the physical-chemical characteristics of polysaccharides and the monosaccharide composition under the influence of metal nanoparticles. Before sowing, seed treatment was carried out with suspensions of nanoparticles with a concentration of 0.5 g/ha (hectare seed sowing rate). Observed under the influence of copper nanoparticles, the yield increased by 15 % comparison to the control one. When determining the monosaccharide composition, in addition to changing the quantitative content of monosaccharides, a high concentration of galacturonic acid was observed, especially when treating seeds with copper nanoparticles before sowing.
