Preservation in culture of a rare species Paeonia mlokosewitschii Lomak.
The paper presents the results of introduction of rare species from Russian flora Paeonia mlokosewitschiiLomak. based on the South-Ural Botanical Garden-Institute of Ufa Federal Research Centre of Russian Academy ofSciences. The data on phenological observations, morphometric parameters and elements of seed production of the speciesin culture are shown. According to the complex of biological and economic characteristics (flowering, reproductivecapacity, the duration of flowering, flower size, the total resistance) P. mlokosewitschii seems as promising for culture,which makes it possible to keep this species ex situ, and to obtain plants for planting for the reintroduction. The resultsof studying the influence of plant growth regulators (Biodux, Energen, K-Humate-Na & mineral) on soil germinationand biomorphological parameters of P. mlokosewitschii are presented. It was found that the maximum value of seedgermination (87 %) was obtained in the variant of the experiment using the drug Biodux.
