Background. The study effects of plant growth and development regulators (stimulants), increasing sowing qualities of seeds, on development soil microorganisms. Materials and methods. In study carbon dioxide allocation by systems “germinating seeds – substrate” when testing with live and mortified seeds winter triticale variety “Nemchinovskij 56” managed by entering a certain approximation, to divide and to estimate the carbon dioxide fluxes emitted by microorganisms of soil and seeds. Results. On this basis, it was found that pre-sowing seed treatment with stimulants activates the development soil microorganisms to a much greater extent than accelerates the biochemical processes in the seeds. Moreover, the soils on the effect of accelerated development of microorganisms on the biochemical processes in the seeds differ from each other. The results obtained show that stimulant preparations act not only on seeds, but also on soil microorganisms and, apparently, seed microorganisms, and result of their action on microorganisms to change the rate biochemical processes passage in seeds cannot be predicted in advance, since the pathogens action in soils is unknown. Conclusion. In this regard, it is difficult to expect that development of stimulants using inert substrates without taking into account the interaction these stimulants with soil microorganisms can give positive results.
