Abstract
The study of soils, in particular their allelopathic and microbiological features, remains an important but seldom investigated aspect in the cultivation of Phlox paniculata L. The microbial groups of the root soil and its biological activity for different Phlox paniculata L. varieties have been studied. Soil samples were taken from the collection site of the flower and ornamental plant department of the M.M. Gryshko National Botanical Garden. The samples were taken from the central parts of plant populations of the Phlox paniculata L. varieties introduced in Ukraine during the period of their greatest activity - the budding and flowering. Allelopathic activity of the soil was determined by direct biotesting. Microbiological analysis was carried out according to methods generally accepted in soil microbiology. It has been established that under the action of exometabolites of Phlox paniculata L. the surrounding soil acquires insignificant phytotoxic properties. The smallest number of functional and ecological trophic groups of microorganisms was found in the rhizospheric soil of the Panianka variety. In the soil of the Novinka variety, which contained the largest number of the investigated microorganisms, microbiological processes were also the most intensive. We conclude that the number of microorganisms is naturally associated with the varietal characteristics of Phlox paniculata L., the accumulation in the soil of the allelopathic active substances and the intensity of the physiological processes occurring in it.
