Creating a stimulator to increase sowing qualities of seeds on the basis of yeast autolysate

Abstract

The use of yeast autolysate as a stimulant to accelerate the development of seeds leads to activation of development processes in the seeds and in epiphytic and endophytic microorganisms. The method of seed treatment has a great influence on the direction of action of biofertilizers. A biofertilizer based on brewer’s yeast autolysate (BYA), containing 0.5–1% of live yeast cells, appears to be a promising stimulant of development during presowing seed treatment. A complex biofertilizer based on BYA and containing gibberellins and humates has been developed. Its suspensions have good operational properties and stable effectiveness in application.
