The efficiency of mobilization of woody plants is determined by the method of phenological observations, which makes it possible to obtain an array of data on the characteristics of growth, seasonal frequency and the correspondence of the development of vegetative and generative organs of plants to local climatic conditions. Bioresource collections of the Federal Scientific Center of Agroecology, Integrated Land Reclamation and Protective Afforestation of the Russian Academy of Sciences (№ 34: 34: 000000: 122, 34: 34: 060061: 10) and its branches (Lower Volga Station for the selection of tree species; № 34: 36: 000014: 178, west Siberian AGLOS; № 22: 23: 010003: 0014) were the object of research to predict their prospects for introduction into culture. An increase in precipitation deficit during the growing season (with an annual amount of 262-417 mm) and indicators of average monthly air temperatures was established. These conditions influenced the duration of the passage of phenological phases in 47 taxa of trees and shrubs of various botanical families and geographic origin (North America, Europe, the Caucasus, Crimea, the Far East, Central Asia, Japan, China, Korea). It was revealed that the phase of the onset of massive leaf fall occurs more than 20 days later ( Larix sibirica , Ulmus pumila , Quercus borealis , Quercus robur , Acer platanoides , Tilia platyphyllos , Fraxinus excelsior ). In some species – Celtis occidentalis , Acer negundo , Juglans nigra , Amelanchier ovalis , the deviation in the duration of the growing season averaged 13-15 days; the duration of shoot growth in Celtis occidentalis increased by 37 days, in Amelanchier ovalis – 29, Tilia platyphyllos – 22. A different-year-time schedule of the onset of phenophases and their frequency characteristics are given, taking into account solar (12,5-16,5 hours) and heat resources (5-24 °C) of the corresponding ten days of April-October (Kamyshin, Volgograd region). In 90 % of tree species, the onset of the budding phase is ensured with sunshine for more than 13.5 hours and an average daily air temperature of 5 to 15 °C. The integrated quantitative method established the correspondence of the biorhythms of plant development in terms of the duration of the growing season, taking into account their lag or lead in relation to the general norm characteristic of the region.

State Agrarian University, Saratov The article discusses the results of a mathematical analysis of the study, which includes 25 samples of the grass pea and 21 indicators characterizing the vegetative characteristics and biochemical composition of the grain. Grass pea (Lathyrus sativus) is widely cultivated in arid conditions of southern countries for fodder and food purposes, as well as a green manure crop. A weak difference between the samples (V˂10 %) was noted in the length of the stem (53,9-78,8 cm), the length of the bean (27,8-40,8 mm). According to such features as: the height of attachment of the lower bean (13,6-20,2 cm), branching (5,9-10,3 pieces), width of the bean (9,3-15,8 mm), the sample was characterized by the coefficient of variation of the average degree. Significant differences were revealed according to the studied characteristics of variety samples (factor A). According to the factor of the year (B), there were no significant differences in characteristics: the width of the bean, the number of seeds in the bean, the weight of 1000 seeds, the ash content in the seeds. The output of gross energy with seeds in varieties of grass pea varies within 16,66–33,51 GJ/ha. The contribution of nutrients to the gross energy output was: protein – 5,88–12,31 GJ/ ha, fat – 0,18–0,64 GJ/ha, fiber – 0,79–2,13 GJ/ha, without nitrogenous extractive substances – 9,55–18,96 GJ/ha. In the experiment, a high total contribution to the overall variability of the studied traits (variety factor A) and the interaction of the genotype and year (AB) was revealed, while the effect of the year factor (B) does not exceed 7,5 %. The food and fodder directions of the use of the grass pea are due to the presence of a large amount of protein and fiber in the

Population distribution and population density are relevant economic and geographical indicators of spatial planning and management. The Russian Federation as a unique territorial entity needs economic and geographical analysis and expertise in order to determine the types of subjects of the country by population density in conjunction with the socio-economic interpretation of this geographical indicator. Research objectives: 1) implementation of the socio-economic assessment of population density; 2) determination of the types of subjects of the Russian Federation by density levels and the level of socio-economic assessment of population density; 3) geographical examination of population density – a conclusion on the geographical patterns and paradoxes of population density and the socio-economic situation of the constituent entities of the Russian Federation by comparing the constituent entities of the country with models of territories based on the World Bank review. To solve the problem of performing a socio-economic assessment of population density, the authors calculated an integral indicator of the socio-economic assessment of population density. To determine the types of subjects of the Russian Federation by levels of density and the level of socio-economic assessment of population density, the subjects were grouped according to these indicators and a corresponding geographic matrix was compiled. The regions of the country with low population density, located in the Ural, Siberian, and Far Eastern Federal Districts of the country, far from the European center, became the nuclei of the high estimate of the population density.

elevations of the Katunsky Range of the Russian Altai Mountains (the upper reaches of the Akkem river as an example). The upper forest line is a strip between the upper line of closed forests and the upper line of the single trees. This line is the most important biogeographic boundary and an internationally recognized indicator of climate change. The following upper lines are defined on the slopes of the Akkem river valley: closed forest lines (2300 m a.s.l. on the eastern slope and 2200 m a.s.l. on the western slope); tree group lines (2330 and 2265 m a.s.l., respectively); single tree lines and seedling lines (2440 and 2290 m a.s.l., respectively). Closed forests are grass-reed-green mossy and grass-cowberry-green mossy Siberian stone pine ( Pinus sibirica ) and Siberian larch ( Larix sibirica )-Siberian pine forests with 2-3 generations., The age of pine and larch trees of the first generation is 270–400 years, of the second generations is up to 180 years on the eastern slope and the age of the trees of the first generation is 530–590 years, of the second generation is 250–440 years, and of the third generation is up to 140 years on the western slope. On the eastern slope of the Akkem river valley, Siberian stone pine is mainly formed the tree group lines and single tree lines and Siberian larch do on the western slope. The seedlings is absolutely dominated by stone pine, larch seedlings older than 18 years is rare and the younger seedlings are absent. All lines are very tortuous. The altitude of the lines is significantly (up to 80 m) reduced on the western slope as compared with the eastern one due to the active landslide processes. The reproductive line of the Siberian stone pine is 2370 m a.s.l.
