INFLUENCE OF CULTURAL EXTRACT FROM MICROORGANISMS ON GERMINATION AND DEVELOPMENT OF WHEAT

Abstract

This article examines the growth-stimulating properties of strains to develop an effective biological product based on microorganisms to increase the germination of crops. In the microbiological laboratory of «БИО-KATU» LLP, the microflora of various types of soils, sludge, horse and cow manure was studied, and 45 pure cultures of microorganisms were isolated using the microbiological method. The influence of strains on the growth parameters of durum wheat seeds was studied under laboratory conditions. The growth-stimulating properties of the isolated strains had a positive effect on the quality of durum wheat seeds. Inoculation of seeds with cultural filtrates improved the growth of durum wheat seedlings and their physiological parameters, including a slight increase in the length of roots and shoots; on the contrary, some microorganisms, for example, strains №13, № 15, № 31, № 43, had a negative effect on the germination of durum wheat seeds. wheat. In these options, the decrease in germination compared to the control was 2-22%. It was found that 11 out of 45 isolated strains are capable of increasing seed germination to 100%. Microorganism strains № 40, № 39, № 34, № 19, № 45, № 14, № 37, № 32, № 41, № 26, № 29, № 10, № 25, № 28, № 33 isolated from different substrates, № 8, № 14, № 23, № 25, № 28, № 33, № 40, № 43, № 46, which have cytokinin and auxin effects, are recommended for use in the creation of new biological products and microbial fertilizers to stimulate the growth of wheat.
