It is shown that the deposition of silica sol shells on the surface of barley seeds based on hydrolyzed tetraethoxysilane with the addition of γ-Fe 2 O 3 (maghemite) nanoparticles leads to a nonlinear change in the transparency in the UV region of distilled nonsterile and sterilized water after contact with the treated silica-salt seeds, depending on the concentration of the oxide additive introduced into the silica sol, varying in the range 0.001–10 000 mg/L. A number of correlations are found between the transmittance of the studied water samples and the target indicators of seed germination, which may be due to a change in the permeability and sorption activity of the shell being formed.
