Essay

The results of research of micro- and mycobiota rhizosphere of 47 steppe plants of three branches Ukrainian steppe natural reserve are given. The essential differences in dynamics of number of microorganisms of basic taxonomical groups of the steppe plants rhizospheric on seasons vegetation are revealed. The changes of quantitative and qualitative parameters of earth microbiota and biological activity of a ground under antropogenic intervention (grass stand cutting) are shown on an example Mykhailivska tsilyna. The high similarity between rhizospheric species micromycetes steppe three different on soil-climatic conditions of sections of reserve were established with the help of ecologic data. It is proved the characteristic specific complex mycobiota determined by roots secretes of a plant and soil-climatic conditions for everyone plants communities . The allelopathic activity of rhizosphere of researched high plants of reserve's branches were determined. The absence phytotoxity of effect rhizosphere of a ground of the majority of kinds of steppe plants was established. The collection of microscopic cultures micromycetes and spore-forming bacteria was present.
