Plant-microbe interaction associating of diazotrophs and introdutsentоv

In plant-microbe interactions of exotic species (videopussy of the genus Amaranthus L.) and rhizosphere diazotrophs is the mutual stimulation of macro - and microorganisms, which is the basis for improving the productivity and sustainability of amaranth to different stress factors. The community composition of rhizosphere nitrogen-fixing microorganisms amaranth dominated by representatives of the genera Azotobacter and Azospirillum, which constitute of the total number of diazotrophic microflora depending on the phase of ontogeny 20-35% for Azotobacter and 15-32% for azospirill. For the purposes of bacterization of amaranth formed the consortium of microorganisms, including strains of Azotobacter chroococcum and Azospirillum spp. with increased nitrogenase and antibiotic activity, with the ability to produce metabolites. Revealed the interactions in the system plant - diazotrophy allows you to use the results of the research for deepening the theory of associative nitrogen fixation and its practical application for obtaining ecologically safe phytomass of amaranth.
