Abstract

This article presents the results of experimental studies of the effect of biostimulants Agrinos 1 and Agrinos 2, containing strains of microorganisms Azotobacter vinelandii and Clostridium pasteurinum, etc., as well as a complex of nutrients (macro-, microelements, protein, amino acids, chitin, chitosan) on the activation of metabolic processes and reduction of stress effects on strawberry plants obtained by in vitro method. The effectiveness of the reaction of biostimulants on the adaptive processes of growth and development of microplants of garden strawberry varieties Alba, Kemiya, Clery has been studied. In the course of the research, a positive effect of biological products on the growth of the vegetative mass of plants was established: an increase in the height of the plants compared to the control by 20-25%, the number of leaves by 25-28% and an increase in the root system of plants by 30-40%. In the Clery variety, the use of the biostimulants promoted the formation of the runners. In addition, the introduction of biostimulants into the soil contributed to the improvement of the quality indicators of the soil. The content of nitrate nitrogen in the soil increased by 18%.
