Tryhuba O. Functioning of symbiotic system Lupinus albus ? Bradyrhizobium sp. (Lupinus) for compatible usage of rhizobofit and plant growth regulators

There was shown the dependence of formation and functioning of symbiotic system "Lupinus albus ? Bradyrhizobium sp. (Lupinus)", photosynthetic processes and productivity of Lupinus albus for action of biologics. Compatible seed treatment of lupine sorts under investigation with rhizobofit, strain 5500/4 and PGR Rehoplant has most significantly effect on the nitrogen fixing activity of symbiotic systems, because of the action of rhizobofit based Bradyrhizobium sp. (Lupinus) of strain 367a and PGR Rehoplant increases the content of chlorophyll in leaves, their area, photosynthetic potential of sowings and clear productivity of plants' photosynthesis. It is established that the use of growth regulator Rehoplant compatible with rhizobofit has more effective influence on the symbiotic systems of Lupinus albus ? lupine nodules bacteria, photosynthetic processes of plants and increases their productivity in the conditions of Western Forest and Steppe of Ukraine. The outlined results in the thesis indicate availability of compatible usage of rhizobofit, strains 367a and 5500/4 with the growth regulator Rehoplant in modern technologies of Lupinus albus cultivation.
