Influence of bacterial metabolites from permafrost on morphophysiological parameters of potato material in vitro*

The effect of secondary metabolites bacteria from permafrost rocks on the in vitro morphophysiological parameters potato microplants has been studied. Microplants Zhukovsky ranniy variety were used as object study. experimental results indicate that when are grown together Murashige-Skoog nutrient medium with Bacillus cereus 9-08-CH9 and Achromobacter spanius 10-50TS2 strains introduced at grafting time a dose 250 μl, they have highest inhibitory effect. Secondary these bacterial significant increase number internodes all stages plant cultivation, which can accelerate replication material for original seed production. Metabolites strain 875TS indicated concentrations cause growth inhibition delay development microplants’ root system initial cultivation stages.
