The environmental performance of recreational facilities in Rostov-on-Don was assessed. The object of the study were 15 parks and gardens of the city. Depending on the structure of the territory (the share of the green area, the density of tree planting), the parks were grouped into three groups. The influence of parks and gardens on microclimate parameters was studied - air and surfaces temperatures, air humidity. The greatest reclamation effect on the microclimate is possessed by parks with dense plantations (planting density of trees above 400 pcs / ha). Green spaces have the strongest influence on surfaces temperature, decreasing it by 11.4 - 13.8 ° С. The smallest changes are recorded for air temperature, which decreases on average by 1.9 - 2.3 ° C. Humidity increases by 2.7%. The presence of the effect plantations of trees at parks on microclimate parameters is proved by statistical methods.

For the introduction of sycamore Spanish to in vitro culture most effectively used as explants cotyledonary leaves derived from a three-week seedlings. It is found that the optimal medium for the induction of callus formation is the MS medium supplemented with 2 mg BAP + 0.02 mg of 2,4 D + 0.2 mg IAA. Embryogenesis in callus cells of sycamore with a fairly high frequency induced on MS medium supplemented with 1 mg BAP + NAA 0.1 mg.

To create in Rostov-on-Don, ecologically effective, technologically advanced and durable green plantings to solve the problem: 1. Create a variety of trees for landscaping cities and towns; 2. Determine the principles of green plantings, ensuring their maximum environmental efficiency. In the steppe zone of Russia should use the structure of the park, with a high proportion of dense plantings (400 trees per hectare) of long-lived trees of the first magnitude.

The problem of formation of assortment of wood plants for the South-West of Rostov region. Proposed main and additional assortment of wood plants, including 159 species. In ассотимент included the most sustainable and eco-efficient exotic plants. The assortment includes species not damage the disease of family Betulaceae, toxic and invasive species (Amfora fruticosa, Ailanthus altissima, etc.).
