PHYTOSTIMULATING, ANTAGONISTIC ACTIVITY AND BIOLOGICAL EFFECTIVENESS OF STRAIN BACILLUS SUBTILIS IMB B-7243
Journal Title: Мікробіологія і біотехнологія - Year 2014, Vol 0, Issue 4
Abstract
Aim. Research of the exometabolites phytostimulating activity nature of the strain Bacillus subtilis IMB B-7243 and its antagonistic activity and estimation of the biological effectiveness of pre-bacterization soybean in the field experiment. Methods. Phytohormones were determined by spectrodensitometric thin layer chromatography ethylene – by gas chromatography method, antagonistic activity – by radial strokes against pathogens of soybean bacterial diseases. Results. Phytostimulating activity of the exometabolites B. subtilis IMB B-7243 due to the presence in their composition phytohormones-stimulants (auxins, cytokinins). The ability of the strain to demonstrate middle and high level of antagonism to the agents of soybean bacterial diseases has been shown. Conclusions. Presence of phytohormones-stimulants from the exometabolites and a certain level of the antagonistic activity of the strain B. subtilis IMB B-7243 with respect to the agents of soybeans bacterial diseases had a positive impact on the biological effectiveness in the field.
