Abstract. The main tree species attitude to the main adverse environmental factors (frost, drought, soil salinization, etc.) reflects their biological properties. Knowledge of their features complex is especially important in regions with unfavorable climatic conditions. It can help in the correct selection of the species composition necessary for plantations when they are created. The selection of the main signs of tree species resistance to natural and climatic factors when creating plantings was the main purpose of the research. The article presents the following study results of following tree species: Ulmus laevis Pall., Ulmus pumila L., Gleditsia triacanthos L., Quercus robur L., Robinia pseudoacacia L., Pinus silvestris L., Pinus nigra subsp. pallasiana (Lamb.) Holmboe, Populus alba L., Populus bolleana Louche., Populus bolleana Louche. Kamyshinsky, Populus nigra L., Populus nigra var. italica Münchh., Quercus macrocarpa Michx., Pinus sylvestris L., Pinus ponderosa P. Lawson & C. Lawson, Gleditsia triacanthos L. F. thornless in the archive of populations and plantings of the breeding and seed complex of Kirovskiy district, Volgograd, Novoanninskaya forestry and Kamyshin. It has been established that the main valuable features in the selection are drought resistance, frost resistance, growth rate, biometric indicators, renewal ability, salt resistance. For the first time, the difference in the reaction of robinia and oak plants to the use of physiologically active substances (Humistim, Hera-chlorella, Biostim start) that stimulate plant growth and fruiting was revealed in the study of their drought resistance and transpiration intensity. Data on the fruiting frequency, which is due to the biological properties of tree species, as well as the weather conditions of the growing region, pests and diseases presence identification during the research period were obtained. Recommendations on the studied tree species in various soil and climatic conditions using possibility are given.

Funding. The work was carried out within the framework of task No. 122020100448-6 «Creation of new competitive forms, varieties and hybrids of cultivated, woody and shrubby plants with high productivity, quality and increased resistance to adverse environmental factors. New innovative technologies in seed production and nursery taking into account varietal characteristics and soil and climatic conditions of arid territories of the Russian Federation».
