The impact of the Botanical Garden of Oles Honchar Dnipro National University reconstruction on the soil aggregate structure

The reconstruction factor can significantly affect changes in soil cover. Physical soil properties changes are one of the main reasons for some plant species disappearance and the existing communities disintegration. The variation of soil aggregate structure in the areas affected by the reconstruction and in the areas without such within the Botanical Garden of Oles Honchar Dnipro National University has been studied. It is established that on all sample polygons there is a predominance of content of microfractions (less than 0.25 mm in size). But in the polygons affected by reconstruction, the proportion of microfractions is markedly higher compared to polygons without reconstruction. The sample polygon a, on which the reconstruction was carried out, differs significantly from the others in the lowest content of macrofractions, as well as mesoaggregates of size 7–10, 5–7 and 3–5 mm. At the same time, the highest content of fractions of 1–2, 0.5–1 and 0.25–0.5 mm is observed in this polygon. On polygons that were not affected by reconstruction (polygons c and d), there is a predominance of mesoaggregates 2–3 and 3–5 mm compared to polygons that were reconstructed (polygons a and b). The discriminant analysis made it possible to differentiate the polygons by the aggregate structure pacularities. By the peculiarities of the aggregate structure, the canonical root 1 separates polygon a from all other polygons, and the canonical root 2 opposes polygon b to polygons c and d. Root 1 correlates with the content of aggregates from 3 to 10 mm in size, while root 2 correlates with the content of micro-aggregates and aggregates from 0.25 to 0.5 mm in size. The influence of the reconstruction of the Botanical Garden of Oles Honchar Dnipro National University noticeably affected the aggregate structure of the soil reconstructed polygons, leading to a marked increase in microaggregates and a corresponding decrease in mesoaggregates, favorable for the growth of phytocenosis.

Species from the collection of tropical and subtropical plants of the Botanical Garden of Oles Honchar Dnipro National University in need of protection

One of the current areas of work of the Botanical Garden of Oles Honchar Dnipro National University (Dnipro, Ukraine) is considered conservation, introduction, study of tropical and subtropical plants needed protection. The fund collection of tropical and subtropical plants in protected soil, where the total number of taxa is 830 units from 105 families, and those listed in the Red Book of Ukraine and international lists are more than 70 (28 families), among them, the vast majority of species (60) are included in the World Red List and, in particular, Adiantum capillus-veneris L. – in the Red Book of Ukraine has been studied. The geographical origin and life forms of the collection species needed protection are studied. Their habitats have been found to represent almost all areas of the tropics and subtropics; there are a large number of endemics, including the Galapagos Islands, Madagascar, and the islands of Norfolk and Rodriguez. Among the life forms, most belong to succulents (35 taxa) and trees (20). The taxonomy and systematic position of species according to the classification of the Angiosperm Phylogeny Group (APG IV) have been determined. It has been determined that almost all rare and endangered plants of the Laboratory of the Tropics and Subtropics of DNU have a decorative appearance and can be used in the phytodesign of various interiors, some of them are plants in which fruits, leaves, stems and other parts have a high biological value, in particular as a source of antioxidants, and are a source of physiologically active compounds and vitamins, can be raw materials for the pharmaceutical and food industries. It was found that the largest number among the species in need of protection is the life form of succulents. Among them, the family Cactaceae Juss dominates: 13 genera, 16 species and the family Xanthorrhoeaceae Dumort. – 7 species of Aloe L. The collection of tropical and subtropical plants of the DNU Botanical Garden is constantly used for educational work among the population, thousands of people visit it throughout the year. Protected soil plants serve as the basis for environmental education for adults and children, schoolchildren in particular from the Junior Academy of Sciences, students.

The influence of powdery mildew (Sawadaea bicornis (Wallr.) Miyabe) on chlorophyll fluorescence in Norway maple (Acer platanoides L.) seedlings

The article presents the results of research on impact of Sawadaea bicornis (Wallr.) Miyabe on the state of photosynthetic apparatus in Acer platanoides L. seedlings using a technique of chlorophyll fluorescence induction (ChlF) measurement, which at the present time can be implemented through the use of biosensors. The research was conducted in September 2022 in the territory of the Botanical Garden of Oles Honchar Dnipro National University. To diagnose a violation of the native chlorophyll photosynthesis in fresh leaves of A. platanoides, a portable fluorometer “Floratest” was used (selected spectral range for fluorescence intensity measurement was 670–800 nm). The research was carried out on fresh leaves of Norway maple seedlings both not unaffected and affected with powdery mildew. Analysis of the data obtained indicates a high sensitivity of the parameters of chlorophyll fluorescence induction to damage by the disease regardless of environmental conditions of local growth of A. platanoides seedlings. The high informativeness of induction changes in chlorophyll fluorescence in the structural organization of chloroplasts in Norway maple leaves determined by the parameters Fo, Fm, Fv, Fv/Fо, Fv/Fm, (Fm–Fst)/Fst, (Fp–Fо)/Fv was revealed. This study demonstrated the effectiveness of using the studied chlorophyll fluorescence parameters to detect severe stress in Norway maple seedlings caused by powdery mildew exposure when the fungus affects more than 50% of the leaf blade area. It is further necessary to conduct dynamic studies throughout the growing season to determine the effectiveness of using these parameters to detect mild stress in the early stages of infection. Therefore, our research showed that the method of induction of chlorophyll fluorescence using the “Floratest” device allows you to quickly determine the general condition of the plant by evaluating photosynthesis, which is the main life process. Analysis of chlorophyll fluorescence parameters is a powerful and effective tool for determining the effect of a parasitic fungus on a plant.

The reconstruction impact on the urban ecosystem park plantings on the example of the Oles Gonchar Dnipro National University Botanical Garden

The article is devoted to the study of the reconstruction impact on park plantings located in the Oles Honchar Dnipro National University Botanical Garden. The reconstruction of the botanical garden was carried out in 2018 and consisted of the removal of 74 old trees, sanitary pruning of some plantings, and the laying of asphalt paths. To determine the impact of the reconstruction on the greenery of the DNU Botanical Garden, four test plots were laid down: plots a and b in the reconstruction area, plots c and d in the unreconstructed area. The following physical parameters of the soil were measured at the test sites: soil penetration resistance, electrical conductivity and moisture. The research was conducted in April – May 2021. Soil penetration resistance is an informative indicator sensitive to anthropogenic impact, its measurement is fast and allows obtaining significant amounts of information in a short time. Electrical conductivity is related to soil moisture and salt content. These indicators, combined with phytoindication methods, allowed us to draw conclusions about the impact of the reconstruction on the soil and green spaces. The landfills differed significantly after reconstruction in terms of the profile distribution of average soil penetration resistance values. The reconstruction area soil is characterized by the appearance of peak soil penetration resistance values at depths of 35–50 cm and 85–90 cm. Polygons a and b have much higher values of topsoil penetration resistance than polygons c and d. The coefficient of variation of soil penetration resistance profile distribution at the test sites in the reconstruction zone also demonstrates a specific character – it has a pronounced peak at a depth of 25–40 cm and gradually decreases with depth. The conclusion about the reconstruction impact on the soil penetration resistance of the botanical garden soil changes was made based on the results of the General Linear Model, which was estimated by the Radj2 index. The distribution of soil electrical conductivity values has a pronounced bell-shaped character. At all the test sites, there is a tendency for electrical conductivity increasing which is positively correlated with moisture. By means of the phytoindicative scales the hemerobia index was determined, which demonstrated a statistically significant linear relationship (p < 0.001) with soil electrical conductivity.

Increased soil penetration resistance drives degrees of hemeroby in vegetation of urban parks

Urban parks provide a variety of ecosystem services, and a range of management practices promote their maximisation. The species diversity of plant communities is a factor in the maintenance of ecosystem services. The reconstruction of parks is one of the management practices, but the environmental impact of such activities is not clear. The reconstruction of parks affects vegetation and soil cover, and the interconnection of these components of the urban park ecosystem has not been studied before. The study revealed the features of variability of physical properties of soil and vegetation cover and identified their interconnection in the conditions of urban park reconstruction. The study was conducted in the recreational area of the Botanical Garden of Oles Honchar Dnipro National University (Ukraine). The park was studied in the area where reconstruction activities had previously been carried out. During the reconstruction process, walkways were restored, shrubs were removed, old or damaged trees were excavated, and tree crowns were trimmed. Young trees were planted in place of the removed old trees. Old outbuildings that significantly impaired the aesthetic impression of the park were also dismantled. The reconstruction involved transport and construction equipment. Samples were collected within transects, two of which were located in the reconstruction area, and two other transects were located in a similar area of the park where no reconstruction was carried out. The plant community was found to consist of 65 species. The mean level of alpha diversity was 11.5 species and beta diversity was 5.7. The alpha diversity was higher in the reconstructed park. The principal component analysis of the variability of soil properties extracted four principal components with eigenvalues greater than one. The principal components 1 and 3 reflect the variability of soil properties induced by the park's reconstruction, while the principal components 2 and 4 reflect variability that may be caused by other anthropogenic factors unrelated to the park's reconstruction, or may be due to natural variability of the soil cover. The principal component 1 indicates a uniform increase in the soil penetration resistance as a result of the application of technological processes during the reconstruction. This effect may be the result of the direct technological impact of the mechanisms employed and the large number of employees involved in the park's reconstruction. The condition of the crown space of the park plantation can explain the variation in soil penetration resistance. The increase in the height and projective cover of the grass vegetation is due to a decrease in the closure of the stand crowns, but the effect of such coordinated stand and grass dynamics on soil penetration resistance is observed only at a depth of 25–55 cm. This effect can be explained by the influence of the plant root system on the physical state of the soil. The root system of herbaceous plants is capable of loosening the soil and reducing its soil penetration resistance. The reconstruction of the park led to an increase in the hemeroby of the plant community. The criterion for the success of the reconstruction may be an increase in the attractiveness of the park for visitors without the risk of increasing hemeroby. The trend of increasing hemeroby clearly coincides with the direction of transformation of soil conditions, which are indicated by the principal component 1. The increase in the soil penetration resistance is a driver of the growth of vegetation cover hemeroby. The physical environment of the soil cover acts as an important environmental filter that affects the structure of the vegetation cover and the species composition of plant species complexes.

M-learning in the process of media education and foreign language learning

The purpose of this article is to study the possibilities of English-language mobile applications for media education which are available on the Google Play platform. The main emphasis is on their didactic potential, in particular on their ability to build media literacy skills and improve English language proficiency. The application called Journalism & Mass Communication by Edutainment Ventures — Making Games People Play was chosen as the object of study. This choice is grounded in the attractiveness and successful experience of its use. Other projects focusing on working with English-language texts and expanding vocabulary have also been researched. These ones include Journalism by SQSTECH, Journalism Textbook by Courses Books, Journalism Course by APLUS, Media and Information Literacy by PERCDC Learnhub, Journalism Dictionary Offline by EasyGoing and Journalism Dictionary by Pocket Dictionary. A focus group of students of Oles Honchar Dnipro National University who are majoring in 061 Journalism at various levels of higher education was involved to evaluate the functionality of the applications. In total, there were 17 people in the group, including 12 Bachelor's students, 4 Master's students, and 1 PhD student. The effectiveness or ineffectiveness of the application options was determined by analysing the results of a survey conducted among focus group participants. A general analysis of applications for media literacy and media education shows that mobile learning is a relevant and effective tool in the educational process. However, it cannot completely replace traditional education. The diversity of functionality, approaches to content, and audience engagement underscores the importance of creating mobile applications that cater for specific educational programs. Mobile learning has great potential to improve the effectiveness of extracurricular education. The use of mobile applications in media education and learning English has significant didactic potential. The results of the study confirm the feasibility of an integrated approach to learning, which combines the study of a subject with learning a foreign language. Since the study of the English language is gaining relevance in Ukraine, the combination of these two directions is considered to be well grounded.

DESIGN AND TECHNOLOGY SYSTEM FOR DEVELOPMENT AND OPERATION OF ULTRALIGHT SUBORBITAL ROCKET COMPLEXES

Abstract. Vehicles are called suborbital if they either move along a ballistic trajectory with a flight velocity sufficient to reach altitudes of up to 100 km or more, but insufficient for becoming an orbiter, or fly to altitudes of 100 km or more strictly vertically, but do not become artificial satellites of the planet, even if they reach sufficient velocity at some point. In both the first and second cases, this will be considered a space flight if its height exceeds 100 km (the Kármán line). Despite the active development of the suborbital rocket science in the world as a means of solving many scientific and technical problems in the space and defense industries, scientific research and engineering education, the development of suborbital rocket science in Ukraine has so far remained, at best, at the level of achievements of the 1960s and 1970s and has been supported by numerous amateurs. This article presents the results of the creation and development of a design and technological system for the development and operation of ultralight suborbital rocket systems as the basis for the creation of new models of domestic space rocket systems, rocket and missile weapons systems, the development of innovative technologies in the field of rocket science in general, practical training of highly qualified specialists for the space industry. This paper presents structural and layout diagrams of the developed suborbital rockets, design and technological solutions for the creation of on-board radio-electronic equipment and rocket engines, design modeling, bench and flight tests. The presented design and technological system is already used today at Oles Honchar Dnipro National University for comprehensive practical training of specialists in the field of creation and operation of rocket technology and missile and rocket weapons.

ПОКАЗНИКИ ПСИХІЧНОГО ТА СОЦІАЛЬНОГО ЗДОРОВ’Я ЗДОБУВАЧІВ ВИЩОЇ ОСВІТИ ПІД ЧАС ВІЙНИ

Purpose. The article is dedicated to the investigation of psychological and mental health of students of Oles Honchar Dnipro National University in the war-time. The topicality of the research problem concerns the nature of mental, psychological and social health. The human health as a condition of physical, mental and social well-being is considered from the perspective of the holistic approach. The current state of mental and social health of education seekers in modern conditions determine the relevance of our research. Psychological health is an important component of a person’s social well-being and vitality. Methods. Empirical methods were chosen for the research. The processing of the results of the empirical research was carried out using the calculation of the percentage of people with respect to the levels of manifestation of the selected signs of mental and social health, followed by a qualitative interpretation and meaningful generalization of the data. Results. It is empirically proved that the level of mental health of some students is quite low and only a small part of youth has no social anxiety disorder. Over half of the students have high and above average indicators, but a certain number of students have clinical implications of social anxiety disorder. Subclinical and clinical implications of anxiety are typical for the quarter of students of the 1–3 years of study of Oles Honchar Dnipro National University. The third of them has subclinical and clinical implications of depression. Conclusions. The obtained results testify to the recorded indicators of the level of psychological health of the students of Oles Honchar Dnipro National University. This is a hint about those aspects of psychological health that require special attention in preventive work with students of higher education by the Psychological Service of Oles Honchar DNU. In the conditions of war, the Psychological Service continues to provide psychological help to the participants of the educational process of our higher education institution, focusing on new requests under new conditions.

Images of Great Britain and the British in Russian society during the First World War

The aim of the article is to analyze the general ideas about Great Britain and the British as military allies of the bloc of Entente countries, which existed in Russian society during the First World War. Methods used in the research: the method of content analysis, historical-genetic and historical-comparative. Main results: the article examines the visions of the British, common among the Russian intelligentsia on the eve of the First World War, and the influence of previous historical experience on the formation of these visions. It is analyzed in what way Russians' ideas about Britain as an allied state were transformed during the course of hostilities. Attempts to carry out state actions to promote Britain in the Russian Empire are considered, in particular, the visit of Russian journalists to the British Isles in 1916.Journalistic notes and journalistic works resulting from this visit are examined. Concise conclusions: the experience of the First World War showed that the state propaganda of the Russian Empire paid much more attention to the formation of the image of the enemy. Conversely, efforts aimed at familiarizing Russian society with allies in the bloc of Entente countries were significantly less powerful. At the beginning of the First World War, most representatives of Russian society looked skeptically at Britain as an ally, taking to the attantion the country's lack of general mobilization and its desire to fight only at sea. The experience of the war showed that although general mobilization was not introduced in Great Britain, the number of the British Expeditionary Force in continental Europe increased tenfold due to volunteers who demonstrated high fighting qualities. Britain abandoned the strategy of war exclusively at sea, fulfilling the All-Allied obligations, the country learned to overcome the resource crisis that arose as a result of raids by German submarines on the routes connecting the British Isles with the colonies. It was these messages that Russian journalists and publicists tried to convey about Britain, in particular, the participants of the 1916 visit. However, the number of materials aimed at a mass reader, dedicated to allies in Russia was much less than articles dedicated to the enemy. Even at the end of the war, Russian society looked at the Western Front as an unknown war. Over time, this gave rise to the idea among Russian veterans during the years of the Civil War that Britain and France had failed to fulfill their duty as allies and were guilty of Russia. Practical meaning: the materials of the article can be used in the teaching of the basic course for students of the Faculty of History (Oles Honchar Dnipro National University) at the bachelor's level – “History of Western Europe and North America in modern times”. Originality: for the first time, attention is focused on the fact that the sphere of ideas about the Allies by the Entente bloc during the First World War directly influenced the events at the front and determined the narratives of the USSR and Russian emigration after the world carnage. Scientific novelty: for the first time, the change in perceptions of the British as allies of the Russian Empire (within the Entente countries) during the entire period of active hostilities during the First World War was analyzed. Type of article: descriptive and analytical.

Formation of corporate health in higher education institutions of Ukraine

This article examines the issues of forming of corporate health, the culture of student health in modern learning conditions, spiritual health and the formation of social health of student youth in higher education institutions in Ukraine today. The main goal of our research is the analysis of the formation of corporate health in higher education institutions in Ukraine in the current period. The level of health and physical development of a young people is an important condition to perform the functions of a future specialist and a healthy lifestyle is a factor in social adaptation. The article examines the main factors influencing the physical activity of students, as well as prospects of joining a healthy lifestyle.
 The survey of respondents 1-3 was among students of Oles Honchar Dnipro National University, in November 2021 to study the opinions of respondents. Post-secondary students were involved in the survey. As a result of the survey, 125 questionnaires were received and completed. The questionnaire contained questions about the state of health, regularity of physical activity, respondents' interest in physical activity and attendance at additional sports sections, comments and suggestions on improving the development of physical culture, availability of additional sports events.
 As the analysis of scientific literature shows, researches that study social health problems are becoming more and more relevant. At the same time, a significant part of them is dedicated to the social health of the youth, because the development of each individual country and the world as a whole depends on the social and value orientations of the youth, their position, activity and participation in cultural, scientific, political and social life.

ІННОВАЦІЇ В СУЧАСНОМУ УКРАЇНСЬКОМУ УНІВЕРСИТЕТІ В УМОВАХ РЕФОРМУВАННЯ ВИЩОЇ ОСВІТИ УКРАЇНИ

The article explores the concept of innovation in modern education of Ukraine, which is going through reforms and is referred to by the Ministry of Education and Science of Ukraine as one of the key characteristics of the country’s educational process in terms of integration into academic and educational framework of the European Union. Educational innovation is seen by the author as an upgrade of the entire system, which was made possible with the introduction of an appropriate action plan (new approaches, teaching methods), which improved the system’s performance. The dichotomous nature of innovation is studied as a combination of its static (the statement of the changes that have occurred) and dynamic (the upgrading process as such) aspects. Educational innovations in Ukraine were enabled by the democratization of society and the creation of an overall innovative environment, which laid the intellectual foundation for implementing innovations in national higher education institutions. Based on the analysis of fundamental changes suggested by the Ministry (eliminating education monopoly) and the use of innovative technologies intrinsic to the European education system (credit-module system, interactive learning, project-based learning, person-oriented approach to professional training, distance and blended learning), the author has testified to a more flexible operation system for Oles Honchar Dnipro National University and its subdivisions (the possibility of subdivision-bound management and independence in content development, choice of learning aims and methods, planning research work) as well as to a more student-centered and student-motivating approach (the possibility of choosing activities and tasks, types of educational information leaning on the lesson stages and student’s cognitive profiles). Therefore, educational innovations are forward-looking, yet they require financial support and in-depth understanding.

Comparison of rosulate and short-stemed species of Gesneriaceae Dumort., introduced into the botanical garden of Oles Honchar Dnipro National University

Now conservation of biodiversity is a relevat topic aimed at increasing phytodiversity in both open and closed ground conditions on the basis of botanical gardens The study of the botanical gardens collections is associated with the investigation of new plants that can be used as a new source of antioxidants and objects of hobby and relaxation for the ever-intense nervous system of modern people. Family Gesneriaceae Dumort. is an inexhaustible source of such objects. The study purpose is comparison of the family representatives that are similar in terms of morphological features and ecological needs, and differ in geographical origin, analyzing their adaptive capabilities and identifying the most resistant species and varieties. Observations of representatives of Gesneriaceae were carried out from 2019 to 2022 on the basis of the collection of the stock greenhouse of the Laboratory of Tropical and Subtropical Plants of the Botanical Garden of DNU (48°26'7" N, 35°2'34" E, Dnipro, Ukraine). The research objects were 2 species and 22 varieties of Streptocarpus Lindl., 4 species and 2 varieties of Primulina Hance. The qualitative state and development phases were observed in protected soil conditions. Life forms are listed according to the Catalog of Plants of the Botanical Garden of the National University of Ukraine [12]. The systematic position was determined according to the APG IV classification [13]. The taxonomy and names of plant species are given according to the Catalog of life checklist [12]. According to new taxonomy, the genus Saintpaulia H. Wendl. now joined the genus Streptocarpus Lindl. As a result of the research, it was revealed that among the most decorative representatives of the Gesneriaceae family in the collection of the botanical garden of the DNU, grassy perennials with a short stem or rosette occupy a significant place. Namely, species and varieties from the genus Streptocarpus and the genus Primulina Hance. Plants have similar life forms and ecological needs, occupy the same ecological niches in Africa and Madagascar (Streptocarpus ) and Southeast Asia (Primulina). The greatest resistance to modern conditions of keeping plants of protected soil while maintaining maximum decorativeness is demonstrated by species and varieties from the genus Primulina – representatives of the flora of Southeast Asia. Thus, the adaptive capabilities of 4 species and 2 varieties of Primulina turned out to be better than those of other representatives of the Gesneriaceae collection in general and in particular among rosette and short-stem species.

Materials and methods. Based on the analysis of literary sources, educational programs and pedagogical experience of the department of general medicine with the course of physical therapy of Oles Honchar Dnipro National University, we highlight the peculiarities of the training of specialists in the specialty «Nursing» in the conditions of distance education using telecommunication systems. Results and discussion. The modern development of Ukraine is characterized by a gradual increase in the demand for higher medical education. Today, education is perceived as a strategic commodity and a force of society, which prompts Ukrainian universities to respond to changes, ensuring their existence and development in the conditions of globalization. In connection with the above, the problem of the quality of higher education in remote conditions is gaining the greatest relevance at the current stage of the development of society. A feature of today's medical education is that not only doctors but also nurses have the opportunity to obtain higher education. Today, a nurse is not only a specialist who provides patient care and is an «assistant» to a doctor but a modern nurse is considered a manager and leader of the relevant work in a medical institution. To date, educational and scientific programs in the specialty «Nursing» determine the need to ensure the training of highly qualified specialists capable of implementing the medical and diagnostic process, care and guardianship of patients in health care institutions of various profiles and at home; organization and management of the work of nursing structural units; implementation of the educational process at universities and institutions of postgraduate education, as well as scientific research on nursing problems. The tasks of the educational program are formed on the basis of today's challenges and fully meet the needs of society and the interests of potential employers. Conclusion. The latest educational technologies in the professional training of specialists in the specialty «Nursing» in the conditions of distance education with the use of telecommunication systems should be aimed at the most informative teaching of material and effective conducting of practical classes, which ensures the improvement of the quality of education, the maximum development of individual creative abilities and the adaptation of education to modern requirements, which ultimately leads to a high level of training of future nursing specialists

Specific features of the water regime of the genus Chaenomeles introduced plants in the steppe zone conditions

Sufficient water supply for plants is one of the most important conditions for their vital activity, since most of the biochemical reactions that regulate the plants physiological functions take place in the water environment. The plants adaptive capacity to the influence of a complex of environmental factors in field conditions is largely determined by the ability to maintain water balance, which can be characterized by various features. Among them, the transpiration intensity and the level of water deficit are the most important indicators that are related to the mechanisms of plant resistance to water or high-temperature stress. The aim of the work was to evaluate the introduction success of plants according to the markers of water availability in a new environment. The objects of the study were plants of the genus Chaenomeles, introduced in the Botanical Garden of Oles Honchar Dnipro National University: three natural species (Ch. japonica, Ch. speciosa, and Ch. cathayensis), as well as two hybrids (Ch. × superba and Ch. × californica). Species Ch. japonica naturally grows in humid areas with moderate temperatures, while species of Chinese origin Ch. speciosa and Ch. cathayensis are adapted to mountainous terrain with sharp temperature fluctuations. Water deficiency in the leaves of introduced plants was determined by saturating leaf cuttings with water; the intensity of transpiration was studied by the method of rapid weighing. Both indicators of the water regime in the leaves of introduced plants were measured under contrasting levels of moisture supply during the growing season in the steppe zone conditions: in the wet period, the dry period, and the period of moisture restoration. It was found that during the drought, the intensity of transpiration increased significantly (P ˂ 0.05) compared to the wet period in the leaves of all introduced Chaenomeles plants, the most (by 1.6–1.7 times) in Ch. japonica, Ch. speciosa and Ch. × superba, the least (by 1.3 times) in the leaves of Ch. × californica. Water deficit in the dry growing season in the leaves of all studied Chaenomeles plants increased significantly (P ˂ 0.05), the most in the leaves of Ch. catayensis (2.8 times compared to the wet period), the least in the leaves of Ch. spesiosa (in 2.0 times compared to the wet period). The level of water deficit in the leaves of both Chinese species was lower than that of Ch. japonica (18.85%). In the leaves of Ch. japonica, Ch. speciosa and Ch. × superba was the fastest recovery of the water balance after drought, as well as the most effective regulation of the transpiration intensity level with the onset of drought and during the recovery period. Introduced plants of the species Ch. japonica, Ch. speciosa and Ch. × superba turned out to be the most adapted to vegetation in the conditions of the steppe climate, which is characterized by periods of drought.
