GROWTH-STIMULATING ACTIVITY OF BACTERIA RHIZOBIUM LEGUMINOSARUM, SELECTED FROM LEGUMINOUS PLANTS OF THE SOUTH URAL ^{[№ 9 ' 2017]}
One of the promising methods for the developmrntally-oriented farming is the use of PGPR microorganisms. They can act as an effective growth promoter and, as a result, plant productivity by improving mineral nutrition and protecting against phytopathogens. One of the most important and promising groups of PGPR are the nodule bacteria of the genus Rhizobium, which are widely used in agriculture as associative microsymbionts for nonleguminous economically significant cultures.
The strains R. leguminosarum LSy10 (D18), LVe13 (Inz 2008), PVu5 isolated from legumes of the South Urals were tested on the growth-stimulating activityon seeds of cucumber and physalis plants. It has been shown that the strains R. leguminosarum LSy10 (D18), LVe13 (Inz 2008), PVu5 have growth-stimulating activity and can be used as biofertilizers for physalis and cucumber in the concentration of 107cfu / ml and 105cfu / ml. In addition, it was found that all strains have antagonistic activity against the phytopathogenic fungus F. solani and have a positive effect on plant growth.
Thus, these strains can be used as biofertilizers to protect useful crops from phytopathogenic fungi, as well as to improve plant growth.
