The impacts of physiological alkaline salts NaNO3 and Ca(NO3)2 on the initial period of ontogenesis – the process of absorbing water, swelling and germination – have been studied in wheat and corn seeds. Consequently, physiological impacts of alkaline salts on water uptake and germination of dry seeds had a similar pattern with the control variant as to the kinetic curvature, the difference was only in numbers. Physiological alkaline salts had a negative impact on the germination of seeds, and at a concentration of 0.4 M seeds were not sprouted totally. Negative impact of salts on seeds of corn was particularly high. Ca(NO3)2 compared to NaNO3 had a more negative impact on seed germination. No germination at high concentrations of NaNO3 and Ca(NO3)2 can be explained by the specific impact of ions.
