Development of Corn Root System Under the Influence of Microbial Preparation Polimiksobakteryn

Abstract

Features of development of corn root system of hybrid Dniprovskyi 181 CB under the influence ofthe microbial preparation Polimiksobakteryn (biological agent os which Paenibacillus polymyxa KB is anactive producer of physiologically active substances) were investigated in a vegetation experiment. It hasbeen established that the use of Polimiksobakteryn for pre-sowing bacterization of deeds and surfacetreatment of the vegetative plants in a phase of 3-5 or 7-9 leaflets induces increase in the size of the rootsystem and its adsorption surface. It was shown that the bacteria Paenibacillus polymyxa KB is aproducer of phytohormone substances of auxin nature, which explains the ability of the microbialpreparation Polimiksobakteryn to positively influence the processes of growth and development of the rootsystem.
