Reaction of Sugar Beet Seedlings to Treatment of Seeds with the Chemical Zeroks® (High-colloidal Solution)

Reaction of sugar beet seedlings to treatment of seeds with the chemical Zeroks® (high-colloidal solution) has been studied. The contact bactericide and fungicide Zeroks® (high-colloidal solution) in which silver nanoparticles are its active factor has been used to test growth regulation properties. Non-pelleted seeds have been treated with aqueous solution of the chemical Zeroks® (high-colloidal solution) (3000 mg/l of colloidal silver) in concentrations of 10 %, 20 %, and 30 %. It has been revealed that 10 % solution concentration is the most effective. Here, increase of seed emergence rate (by 4-12 %) and average seedling length (by 16.1-67.5 %) has been noted as compared to the control. The factor of seed treatment had more influence on the “seedling length” parameter than on the "emergence rate" one that testifies to liability of the former in comparison with the latter. Power of influence of sugar beet seed treatment with aqueous solution of the chemical Zeroks (high-colloidal solution) on the “seedling length” parameter was more than on the “emergence rate” one that testifies to liability of the former in comparison with the latter. Individual reactions of a hybrid embryo to the factor of treatment with the chemical Zeroks (high-colloidal solution) are possible; they are positive in seeds with less emergence rate and negative in seeds with high sowing qualities that is the evidence of different seed quality.
