Abstract:
It was shown an essential influence of dispersed solutions of silver nanopowders on processes of
seed germination and sprout growth of some grain and vegetable crops (winter triticale variety Ingen-93,
winter wheat variety H335, spring wheat variety Arnautka 7, tomato varieties Iubileiny, Mikhaela, Surpriz).
Under the impact of dispersed nanosilver solutions
at different exposure durations (30 min., 60 min. and 180 min.)
it has been revealed a stimulation effect (by 10-30%) in some variants. The stimulation was observed in
germination energy and viability of seeds and also in growth of aerial and underground parts of sprouts at
different concentrations of the nanofactor. The task was to study the effect using dispersed nanosilver
solutions at low concentrations. Processing the seeds infected by pathogenic fungi (specific to each genotype)
with dispersed nanosilver solutions we have revealed that the nanofactor has more marked antifungal effect
than solution of potassium permanganate commonly used for these purposes. The Data can be used in
developing a method of pre-sowing stimulation of seed viability with dispersed solutions of metal
nanopowders at low concentrations.
