Peculiarities of the concentration effect of hydrothermal nanosilica in the pre-sowing treatment of plant seeds upon indicators of the germinative energy and germinating ability in laboratory dark growth
The research is devoted to the study of the influence of hydrothermal nanosilica in different concentrations (0.05%, 0.01%, 0.005%, 0.001% and 0.0005%) on seed germination of 11 agricultural crops (15 genotypes). Four types of reaction of germinating seeds to the effect of SiO2 nanoparticles in the specified concentration range have been established. These patterns are typical for both the "seed germinative energy" and "seed germinating ability" indicator, but they do not always coincide for the same crop and variety. In many cases hydrothermal nanosilica contributes to an increase in seed germinative energy (at an early stage of germination) to a greater extent than generating ability.
