After soaking the seeds of grain and vegetable crops (wheat, triticale, tomato) in water dispersed solutions of copper silver nanoparticles (NPAg) and nanoparticles (NPCu) at different concentrations, an essential increase in the germinating energy and seed viability, sprout growth and number of right sprouts were revealed. The effect depends on the nature of nanoparticles, their concentration, the impact time and the genotype of the claimed seeds. The stimulation was revealed under the action of the dispersed solutions at extremely low concentrations of NPAg (up to 10-8 mol/L) and of NPCu (up to 10-17 mg/L). The sol treatment of seeds promoted an increase in the degree of their resistance to pathogenic fungi (causing root rots in sprouts). Treatment of the seeds by the dispersed nanosilver solution at low concentration (10-7 mol/L) led to an essential increase (up to 56%) of the plant productivity in field conditions.
Keywords: water dispersed solutions, nanoparticles of copper and silver, seed viability, ultra low concentrations, low temperature, antifungal effect, germinating energy, length of the main root and the stem of the sprout, number of right sprouts, pathogenic fungi, resistance and productivity of plants.
