Abstract. The purpose of the research is to isolate species of annual and perennial herbaceous plants that are promising for the tasks of accelerating the sequestration of atmospheric carbon, resistant to local soil and climatic conditions and having high productivity from the collection fund of the botanical garden of the Ural Federal University. Methods. The article presents data on the productivity of four types of herbaceous plants: Amaranthus caudatus L., Amaranthus cruentus L., Polygonum weyrichii F. Schmidt and Echinops sphaerocephalus L., grown in the botanical garden. All the research objects were grown under the same conditions. Productivity was measured at the beginning of September. The data were processed using standard statistical methods. Results. It was revealed that the plants P. weyrichii is the most productive in terms of both fresh and dry yield. The yield of the P. weyrichii increases in years with sufficiently high moisture content. Aridity and high summer temperatures have a negative impact on the growth of the P. weyrichii. Amaranths gain a large aboveground mass due to their belonging to the group with the C4 type of photosynthesis. High summer temperatures have a positive effect on the growth and development of amaranths, while correlations with the amount of precipitation are statistically insignificant. The plants E. sphaerocephalus showed average values for productivity and requires further study. It is recommended to grow the plants P. weyrichii in a sufficiently humid area. Amaranth, being a drought-resistant plant, is highly productive in any years, especially in years with the value of the hydrothermal coefficient (HTC) less than 1.0. The scientific novelty lies in the fact that the features of the cultivation of the studied crops are considered not only for forage purposes but also from the point of view of atmospheric carbon deposition and cultivation on potential carbon farms in the changing climate of the region.

The article deals with one of the most relevant topics of the modern city and ecology - the problem of landscaping in Volgograd. The city is characterized by an industrial urbanism, with a high concentration of population, saturation of production facilities and vehicles, which contributes to a high level of negative impact on the environment. The pace of greening of the city lags behind the pace of construction of the residential sector, and the existing green spaces do not meet the sanitary and hygienic, aesthetic requirements. The prospects of this problem are determined, the existing green spaces are considered, data on the climatic conditions of the city and the ecological situation are given. Improvement in the field of landscaping is associated with the scientifically sound placement of green spaces, taking into account all the factors that affect the growth and development of plants in the urban environment. Unfortunately, due to the uneven distribution of the assortment of trees and shrubs, the species composition of the central streets and squares of the city is extremely poor. The study focuses on the role of the botanical garden in urban landscaping and aims to create recommendations for the sorting of tree and shrub plants for urban landscaping. As a result of the analysis of the assortment of ornamental plants of the open ground of the botanical garden, the article proposed species and varieties of woody and shrubby plants that have passed the introduction tests for more than 5-10 years. Recommendations for sorting are aimed at improving the ecological situation of the city and greening the recreation areas of citizens. The proposed list of tree and shrub species cannot fully solve the problem of greening the city, but it will help to significantly enrich the composition of tree and shrub plants.

Representatives of the genus Hortensia (Hydrangea L.) are ornamental shrubs that are highly valued in landscape construction. Today, it is important to create new and reconstruction of existing recreational areas for the recreation of the population. This leads to an increase in the demand for ornamental trees and shrubs as a material for green building. In the Middle Urals, the species of Hydrangea are still rarely used due to the poor knowledge of the bioecological characteristics of various species and varieties under the given growing conditions. The paper gives a characteristic of varying degrees of adaptability to unfavorable abiotic and biotic environmental factors of 14 species and varieties of Hydrangea (Hydrangea) from the collection of the Department of Plant Introduction and Acclimatization, which was planted on the territory of the UdmFIC UB RAS in Izhevsk in 2017. For decorative features, a technique developed by the staff of the Botanical Garden of Ufa was used. Methodological developments on decorativeness of various cultures are taken as a basis. The characteristics of meteorological conditions during the years of research (2019-2020) are given. According to the research results, 7 representatives of the Hydrangea genus were noted as the most promising candidates for green construction in the cities of the Middle Urals. Hydrangea paniculata (H. Paniculata): ‘Lime Light’. ‘Pinkie Winky’, Weems Red ’, Vanilla Fries’. Hydrangea serrata (H. Serrata) 'Bluebird', Hydrangea petiolar (H. petiolaris) and hydrangea tree (H. arborescens). According to the results of two years of observation (2019-2020), these taxa had a decorativeness rating of 50 to 73 points and were assigned to the II group of decorativeness, winter hardiness (5 points). It was noted that unfavorable climatic conditions (moisture deficit, cool May and June 2020) reduced the average decorative score of the entire collection of representatives of the genus Hydrangea by 10 points. This was mainly due to the quality of the flowering.

Seed production of perennial leguminous herbs, including meadow clover (Trifolium praténse), is complicated due to the natural and climatic conditions of the region. In Middle Urals, only two to three years out of ten are favorable for seed production. Estimation of influence of the hydrothermal regime of the growing season and the sowing method has been carried out in the experimental crop rotation of the Udmurt Research Institute of Agriculture, UdmFRC Ural Branch of the RAS with the seed grass stand of meadow diploid clover varieties Pelican and Trio, tetraploid variety Kudesnik It has been revealed that seed productivity of meadow clover on sod-podzolic medium loamy soil was more dependent on the prevailing hydrothermal regimes of vegetation periods, as well as on the variety’s ploidy. A relatively high seeds yield of the Pelican variety (2n) 444-593 kg/ha and Kudesnik variety (4n) 101-116 kg/ha was formed under conditions of insufficient and optimal moisture supply of the vegetation period with a hydrothermal coefficient of 0.67-1.41. With increase in hydrothermal coefficient p to 1.56-1.69, the seeds yield of the Trio variety (2n) decreased to 251-328 kg/ha, of the Kudesnik variety (4n) - to 77-91 kg/ha. Under the same conditions, according to the hydrothermal regime of vegetation, the Kudesnik clover variety formed a relatively larger number of stems and heads, however, the heads productivity was significantly inferior to diploid varieties, which ultimately affected its seed productivity. Sowing diploid varieties of meadow clover Pelican and Trio in the usual ordinary way (15 cm), tetraploid variety Kudesnik in a wide-row way (30 cm) allowed increasing seeds yield and thereby neutralizing the negative impact of weather factors. Sstudy of the seed formation features of meadow clover varieties differing in ploidy in contrasting agrometeorological conditions may be of interest in developing methods for optimizing their seed productivity.

Winter barley is one of the early ripening grain crops. It is the early ripeness combined with high productivity, lesser needs in good growing conditions that determines the great national economic importance of this culture. To increase and stabilize gross yields of winter barley, it is necessary to develop new varieties adapted to the negative environmental factors. The purpose of the study is to identify promising breeding material for winter barley to grow varieties with high agroecological stability and adaptability to local soil and climatic conditions. The studies were conducted in the FSBSI “Agricultural Research Center “Donskoy” in 2015–2018. The objects of research were the commercial varieties “Timofey”, “Yeryoma”, “Vivat”, the new winter barley varieties “Foks 1”, “Marusya”, as well as the promising breeding lines. The weather conditions of 2017 were more favorable compared with those of 2016 and 2018, which allowed producing higher yields. All the studied winter barley varieties, even in the wet conditions of 2017, showed a high resistance to lodging (4–5 points by a 5-point scale). In the spring and summer months of 2018, there was a significant increase in temperature in comparison with that of 2017. In June there were some days with dry wind, and therefore the air humidity dropped to 38% (23% lower than the multiyear average). The analysis of the yield structure showed that in 2016 the winter barley varieties showed higher values of the traits “number of kernels per ear” and “1000-kernel weight”, and “number of productive stems per 1 m2” in 2017. According to a comprehensive estimation, there have been identified the promising winter barley varieties “Marusya”, “Parallelum 1960” and “Parallelum 1962”, which significantly exceeded the standard variety “Timofey” in terms of productivity, and showed complex resistance to leaf diseases. In 2016, the variety “Marusya” was sent to be studied in the State Variety Network of RF through the North Caucasus region.

The purpose and tasks of the work are to analyze the contemporary Ukrainian mass culture in terms of its value and humanistic components, as well as the importance of cultural studies and Ukrainian studies in educational disciplines for the formation of a holistic worldview of modern youth.Analysis of research and publications. Scientists repeatedly turned to the problems of the role of spirituality in the formation of society and its culture. This problem is highlighted in the publications by O. Losev, V. Lytvyn, D. Likhachev, S. Avierintsev, M. Zakovych, I. Stepanenko and E. Kostyshyn.Experts see the main negative impact of mass culture on the quality approach, which determines mass culture through the market, because mass culture, from our point of view, is everything that is sold and used in mass demand.One of the most interesting studies on this issue was the work by the representatives of Frankfurt School M. Horkheimer and T. Adorno «Dialectics of Enlightenment» (1947), devoted to a detailed analysis of mass culture. Propaganda at all socio-cultural levels in the form is similar in both totalitarian and democratic countries. It is connected, according to the authors, with the direction of European enlightenment. The tendency to unify people is a manifestation of the influence of mass culture, from cinema to pop. Mass culture is a phenomenon whose existence is associated with commerce (accumulation in any form – this is the main feature of education), in general, the fact that it exists in this form is related to the direction of the history of civilization.Modern mass culture, with its externally attractive and easily assimilated ideas and symbols, appealing to the trends of modern fashion, becomes a standard of prestigious consumption, does not require intense reflection, allows you to relax, distract, not teach, but entertains, preaches hedonism as the main spiritual value. And as a consequence, there are socio-cultural risks: an active rejection of other people, which leads to the formation of indifference; cruelty as a character trait; increase of violent and mercenary crime; increase in the number of alcohol and drug addicts; anti-patriotism; indifference to the values of the family and as a result of social orphanhood and prostitution.Conclusions, perspectives of research. Thus, we can conclude that modern Ukrainian education is predominantly formed by the values of mass culture. Namely, according to the «Dialectic» by Horkheimer and Adorno, «semi-enlightenment becomes an objective spirit» of our modern society.It is concluded that only high-quality education can create the opposite of the onset of mass culture and the destruction of spirituality in our society. It is proved that only by realizing the importance of cultivating disciplines in the educational process and the spiritual upbringing of the nation, through educational reforms, humanitarian knowledge will gradually return to student audiences.Formation of youth occurs under the influence of social environment, culture, education and self-education. The optimal combination of these factors determines both the process of socialization itself and how successful it will be. In this context, one can see the leading role of education and upbringing. It turns out that the main task of modern education is to spread its influence on the development of spiritual culture of the individual, which eventually becomes a solid foundation for the formation of the individual. Such a subject requires both philosophical and humanitarian approaches in further integrated interdisciplinary research, since the availability of such research will provide the theoretical foundation for truly modern educational and personal development.

Red Currant

Powdery mildew is one of the most harmful fungal diseases that causes economically significant damage to berry plantations. The disease is common in all areas of currant cultivation in the Russian Federation. In this regard, in modern conditions of intensive berry growing, the problem of breeding cultivars that are highly resistant to diseases and pests becomes urgent. Breeders have a difficult task to combine the adaptive potential of the cultivar with its annual high productivity and resistance to biotic environmental factors. When studying the adaptability of introduced cultivars of red currant and selected forms of the Institute to local soil and climate conditions, the following cultivars were identified as sources of economic and useful characteristics and involved in selection: ‘Belaya Potapenko’ as a complex source of resistance powdery mildew and high marketable and taste qualities of berries; SS 1426-21-80 as a source of high productivity and long racemes (raceme length 11-13 cm; up to 20 berries in the raceme). On their base the selection family of red currant has been developed: Belaya Potapenko × ♂SS 1426-21-80. The study of data on the destruction of hybrid seedlings of the selection family by powdery mildew showed that in epiphytotic conditions, the percentage of intensity of the disease development varies over the periods of screening from 0.2% in May to 20.4% in June. Such indicators served as a prerequisite for conducting a comparative test of breeding material in the field under artificial infection with powdery mildew. After artificial infection on the background of epiphytosis, the rate of intensity of the disease development increased slightly and amounted to 35.6% for the family. There were 30 highly resistant seedlings in the family, 10 of which have remained stable and highly resistant since 2018. In these plants we can assume the presence of the so-called field resistance, controlled by polygens, each of which does not give a visible effect of stability, but with different combinations determines one or another of its degree. Highly resistant seedlings will be used in further breeding studies to identify new sources of resistance to powdery mildew.

Domestic Hot Water

According to the authors of this paper, the mathematical point of view allows us to see what sometimes cannot be seen from the designer’s point of view. The aim of this study was to estimate the influence of the most important parameters (volume of heat storage tanks, daily consumption of domestic hot water, optical efficiency, heat loss coefficient, and total area of a solar collector) on the thermal power output of solar domestic hot water (SDHW) system in European climatic conditions. Three deterministic mathematical models of these relationships for Madrid, Budapest, and Helsinki were created. The database for the development of these models was carried out using computer simulations made in the TRNSYS software environment. The SDHW system located at the Bialystok University of Technology (Poland) was the source of the measurement results used to validate the simulation model. The mathematical optimization procedure showed that the maximum annual useful energy output that can be obtained from 1 m2 of gross collector area is 1303 kWh in the case of Madrid, 918.5 kWh for Budapest, and 768 kWh for Helsinki weather conditions.
