Effect of Rhizospheric Bacteria Capable of Biosynthesis and/or Destruction of Phytohormones on the Growth Characteristics and Hormonal Status of Wheat Plants in Conditions of Water Scarcity

The ability of various strains of soil bacteria to synthesize and/or destroy plant growth regulators: indolyl-3-acetic acid (IAA), cytokinins (CK) and abscisic acid (ABA) has been shown. Bacteria stimulated the growth of shoots and roots of soft wheat under normal conditions of moisture and drought, had a significant effect on the content of phytohormones in shoots and roots of plants. The most promising growth stimulators were strains with an average level of IAA production in combination with the ability to destroy phytohormones: Pseudomonas protegens DA1.2, P. plecoglossicida 2.4-D and the cytokinin-producing strain P. chlororaphis IB-6.
