Acceleration of propagation of source material for Sorbus Sensu Lato Breeding

Aim. The permanent growth of interest in rowan and other currently underestimated Sorbus sensu lato crops has prompted the search to improve the accelerated propagation technique of its most valuable genotypes for breeding. Methods. The experiments involved 3–7-year-old Sorbus sensu lato plants from the National Dendrological Park "Sofiyivka" of the National Academy of Sciences of Ukraine collection. Statistical analysis of the experimental data was performed according to Ronald Fisher. Results. It was found that the germination rate of the studied sorboid plants depended on the method of seed preparation. In contrast, the grafting efficiency depended more on the grafting method than on the graft genotype. The use of our modified MS media allowed us to obtain clone formation coefficients (6.6–7.9) sufficient for effective micropropagation and to induce morphogenesis with 59.9–88.8 % of rooted microclones, as well as to achieve stable results of adaptation of the studied Sorbus sensu lato to non-sterile ex vitro conditions both in peat disks (69.1–90.3 %) and in containers with soil substrates (70.4–93.0 %). Conclusions. The results of comparing the methods of accelerated propagation of source material for breeding sorboid crops obtained in long-term experiments showed the advantages of micropropagation and the prospects for introducing the micropropagation link into breeding practice and nursery of the most valuable for horticulture Sorbus sensu lato.

The first record of Illinoia liriodendri (Monell, 1879) (Hemiptera, Aphididae) from Ukraine

Illinoia liriodendri is reported for the first time in Ukraine as a new invasive species of aphids. It was found feeding on Liriodendron tulipifera at the ‘Olexandria’ State Dendrological Park of the NAS of Ukraine in June 2024.

Epiphytic bryophyte communities of the Dendrological Park “Olexandria” of the NAS of Ukraine

The article presents the results of research on epiphytic bryophyte communities of the Dendrological Park “Olexandria”. The study was conducted in the historical part of the arboretum in 2021. Among the investigated phorophytes were the following tree species: Acer platanoides, A. pseudoplatanus, Betula pendula, Carpinus betulus, Fraxinus excelsior, Quercus robur, Populus sp., Salix babylonica, and some others.The research results showed that the epiphytic bryophyte vegetation of the historical part of the Dendrological Park “Olexandria” is represented by two unranked communities and 11 associations belonging to six unions, four orders, and three classes. The most widespread in the arboretum are the associations Dicrano scoparii-Hypnetum filiformis, Platygyrietum repentis, Leskeetum polycarpae, and the rankless community Leucodon sciuroides of the class Frullanio dilatatae-Leucodontetea sciuroidis.It is shown that in terms of the number of detected bryophyte associations, the Dendrological Park “Olexandria” is similar to the National Nature Park “Homilsha Woods”, which is located in the Kharkiv region (hosts 11 reported associations) and the Nature Reserve “Kanivskyi” in the Cherkasy region (12 reported associations). However, it is poorer than the National Nature Park “Holosiivskyi” in Kyiv, where 16 bryoassociations were registered.

Peciliarities of Hormonal Regulation of Growth Rate and Generative Functions of Fishes under Increased Anthropogenic Influence

The hydrochemical parameters, the production and destruction of organic substances in different areas on the Ros and Protoka rivers were studied. Nearby the Horodyshche vil. (Ros River) and Pishchana vil. (Protoka River), concentration of ammonium nitrogen exceeded control values 2-5 times, nitrites - 1.5-2.5 times, nitrates - almost 3.0-5.8 times (as control the Ros River in the Olexandria dendrological park was used). Water of the considered sections was significantly contaminated by pesticides (chlorpyriphos) from the adjacent territories. Elevated content of nutrients in water conditioned intensive production processes (Pishchana vil.), whereas high chlorpyriphos content (Gorodyshche vil.) along with significant concentration of chlorpyriphos (Gorodyshche vil.) suppressed organic matters' production. The water quality deterioration and presence of the toxic contamination caused decrease of the size-mass parameters of common ruff, river perch and common rudd, mainly owing to decrease of somatotropin content in blood. The gonadosomatic index of perch and rudd females from contaminated water bodies increased, whereas in males it decreased as compared with the control. The relative and absolute fertility of rudd increased along with increase of the contamination degree. The females' fertility growth under the unfavorable conditions was associated with increase of the estradiol content in blood. The perch and rudd males were characterized by decrease of the gonadosomatic index along with decrease of the testosterone content in blood. Decrease of size and mass parameters and increase of the females' fertility is an adaptive response aimed at the population maintaining and higher vitality under toxic environment. These processes are provided by hormonal regulation of metabolic processes.

Revitalization of regular landscapes of the Arboretum exposition zone of the State Biotechnology University

Purpose. To substantiate the concept of revitalization of regular landscapes of the exposition zone of the dendrological park of the State Biotechnological University. Methods. Field, laboratory, geoinformation, computer modeling (QGIS 3.28.3-Firenze 2022-08-31, Realtime Landscaping Architect 2023.02, Trial Free Version and Sketchup). Results. The historical context of the creation of the arboretum, the agro-ecological status of the elements of soil fertility, its trace element status, the ecological-ameliorative and ecological-toxic state were studied. The selection of introducers was carried out for the 5A climatic zone of winter hardiness (USDA-zone). Geoinformation modeling of the studied space was carried out, relief isolines were created. A revitalization project of regular landscape compositions of the exposition zone of the dendrological park has been developed. Taking into account the soil and climatic conditions in the formation of plant compositions requires the use of introducers that do not require a high level of available nitrogen compounds, but respond well to an increased content of mobile phosphorus and potassium, do not lose decorativeness when grown without irrigation or with the use of minimal soil protective irrigation, with high resistance against diseases and pests and will serve to increase the biological diversity of the urban landscapes of Kharkiv and other cities of Ukraine located in the 5th winter hardiness zone (USDA zone). Conclusions. It is proposed to preserve the approach proposed by the founders of the dendrological park, that is, to restore the decorativeness and expressiveness of plant compositions, but in the context of making nature-oriented decisions, to enrich this approach with an ecological feature.

Biota of the F.E. Falz-Fein Biosphere Reserve «Askania Nova» of NAAS

The article provides a general overview of the biota of the «Askania Nova» Biosphere Reserve named after F.E. Falz-Fein of NAAS based on existing reports and updating of some inventory data. The information on the area, functional zoning and physical and geographical location of the territory is presented. The original, historically defined infrastructure of the Askania Reserve Complex is noted, which significantly differs from the objects of the nature reserve fund of Ukraine due to the combination of natural ecosystems of virgin fescue-fescue steppe with plantations of the irrigated dendrological park and the zoo with semi-free keeping of wild ungulates. It is emphasized that such a combination of nature protection functions and heterogeneity of the natural-territorial complex determine a high level of biodiversity, including its rare component. Thus, the indicated heterogeneity of the Reserve's territory, as well as the succession of natural ecosystems, invasions and related consequences of introduction require periodic re-inventories, critical audits, coordination and systematization of general floristic and faunal summaries of the territory, individual species lists in the context of functional zones, and clarification of the sozological status of species. Existing materials on the biota diversity and the list of rare species of flora and fauna of the «Askania Nova» Biosphere Reserve have been consolidated into a single, comprehensive list, which illustrates the full species composition of natural and artificial ecosystems of different functional zones, proves the factual richness of the current version of the general biota summary, provides the necessary cadastral information and methodological basis for assessing the environmental damage caused by the armed aggression and occupation of the territory. Currently, the biodiversity of the «Askania Nova» Biosphere Reserve, including the dendrological park of national importance and the zoo, comprises 2570 species of phytobiota (vascular plants — 1762, bryophytes — 54, algae — 285, fungi — 330, lichens and lichenicolous fungi — 139) and 2292 species of zoobiota (invertebrates — 1945, vertebrates — 347). The biota includes 167 species of flora and 307 species of fauna with national, regional, and international protection status.

Falz-Fein Biosphere Reserve "Askania-Nova" (dedicated to the 125th foundation anniversary)

We studied the history of F.E. Falz-Fein Biosphere Reserve “Askania-Nova”, which can be divided into several periods. The first period is the founding of Askania-Nova estate by the German Duke F. Anhalt-Kothen (1841). The second period is associated with F.E. Falz-Fein activities: the organization of a zoo with semi-free animals (1874), the establishment of a dendrological park with artificial irrigation (1887), the bequest of virgin steppe territories (1898). The next period of the reserve’s existence took place in the conditions of revolution, civil war, repressive measures of the Soviet authorities, and World War II. It was nationalized (1919) and renamed many times, including the State Steppe Reserve (1921), the All-Union Research Institute of Animal Hybridization and Acclimatization (1933), M.F. Ivanov Ukrainian Animal Husbandry Research Institute of the Steppe Regions (1956), Ukrainian Biosphere Reserve (1983), which was included in UNESCO International Network of Biosphere Reserves (1984). The last period began with Ukraine gaining independence (1991) and continues to this day.

Genus Corydalis s. l. (Papaveraceae) in the flora of Ukraine: wild and cultivated taxa and the success of naturalization of alien species

Taxonomic composition of native and alien plants of the genus Corydalis s. l. in the flora of Ukraine has been analyzed. Based on literature, herbarium, inventory and other information, it was established for the first time that 3 native taxa (outside natural ranges) and 16 alien taxa of the genus Corydalis were recorded among ergasiophytes in botanical gardens and dendrological parks of Ukraine. The majority of these ergasiophytes (73.7 %) have not been preserved in the collections of living plants, indicating a low level of naturalization. The leading scientific center for the plant cultivation, where 82.4 % of alien taxa of the genus Corydalis have been cultivated, is the M. M. Gryshko National Botanical Garden of the National Academy of Sciences of Ukraine (Kyiv). Additionally, 4 alien taxa at different stages of naturalization were noted in the spontaneous flora of Ukraine. These include the ephemerophyte C. bracteata, colonophyte C. lutea, epecophyte C. cava subsp. marschalliana (outside the natural range) and hemiagryophyte C. caucasica. In the conditions of M. M. Gryshko National Botanical Garden and Syretsky Dendrological Park (Kyiv) ontogenetic structure of native coenopopulations of C. solida and introduced coenopopulations of naturalized alien taxa C. cava subsp. marschalliana and C. caucasica have been found. It was found that the coenopopulations of C. solida belong to the mature or aging types; C. cava subsp. marshalliana – to the young type; C. caucasica – young with a bias towards an invasive type. The highest density and a high seed germination in various coenotic conditions, which emphasizes the invasive nature of this species, distinguish coenopopulations of C. caucasica. Its expansion in the conditions of the M. M. Gryshko National Botanical Garden corresponds to the existing trend of the invasive spread of alien species from the southern regions, which is intensified by Global Climate Change. Due to the invasive activity of C. caucasica, this alien taxon, according to existing recommendations, should be considered as an invasive plant at the initial stage of expansion, so it should not be recommended for introduction to other countries and should be prevented from spreading in Ukraine.

Specialized objects of landscape architecture of the city of Novosibirsk

Today, a modern large city can only be imagined with specialised landscape objects. They belong to the group of public facilities, the functional feature of which is formed, as a rule, under the pressure of the city’s cultural, social and historical environment. The presence of such facilities provides a wide range of recreational activities and contributes to the multifaceted development of the personality of visitors. The article presents a methodology developed by the authors for assessing the attractiveness and integration into the urban gardening system of specialised objects of landscape architecture in Novosibirsk. The proposed method makes it possible to determine the popularity of an entity among the population, its accessibility, its performance of the prevailing function, the possibility of social integration of people with disabilities, and the organisation of the landscape on the territory. Five specialised objects of various functional orientations were identified in the structure of Novosibirsk. Among them, parks of communication with nature and protect flora and fauna prevail in number (Central Siberian Botanical Garden, Dendrological Park, Novosibirsk Zoo named after R.A. Shilo). These objects are also the most popular among the residents of the city. The main factor in attracting visitors to such sites is the cognitive function. The historical and architectural open-air museum needs to be better integrated into the system of urban landscaping due to poor awareness of citizens about this object, the lack of developed transport and pedestrian communications and unhindered access for all categories of citizens. The dendrological park needs a reconstruction of the landscape organisation and functional zoning of the territory; for this object, the problem of popularization among the city’s residents is also relevant in the course of the analysis of specialized landscape objects of Novosibirsk, the Central Siberian Botanical Garden, the Central Park, the Novosibirsk Zoo named after N.N. R.A. Awl. However, none of them fully meets all the necessary criteria. Reconstruction of varying degrees is required for each facility, considering social trends and modern processes.

Peculiarities of the development of reproductive organs of ornamental crabapples (Malus spp.) depending on drought resistance

The current task for both pomiculture and ornamental horticulture is the formation of plant cultivars resistant to different environmental stress and maintaining their high productivity. Drought is one of the most significant environmental factors that inhibit plant growth and development and cause a set of morphological, physiological, and biochemical changes in plant organisms. The aim of our research was to discover the relationship between the development of the reproductive organs of ornamental crabapples and the physiological indicators determined by drought stress factors. The four species and three cultivars of the ornamental crabapples (Malus spp.) from the collection of the National Dendrological Park “Sofiyivka” of NAS of Ukraine were involved in the study: M. × floribunda Siebold ex Van Houtte, M. halliana Koehne, M. niedzwetzkyana Dieck, M. × purpurea (A. Barbier) Rehder, M. × purpurea ‘Ola’, M. × purpurea ‘Royalty’, and M. × purpurea ‘Selkirk’. Drought resistance was determined by the following quantitative indicators: leaf water content, relative turgidity, leaf water deficit, and excised leaf water retention capacity. The leaf water content ranged from 60.0% (M. × floribunda) to 67.2% (M. × purpurea), the relative turgidity ranged from 81.7% (M. × purpurea ‘Ola’) to 98.9% (M. halliana), and the leaf water deficit ranged from 6.8% (M. halliana) to 24.4% (of M. niedzwetzkyana). As a result, the leaves of M. halliana lost the smallest amount of water in 24 hours (50.2%), whereas M. × purpurea 'Ola' leaves lost the largest amount (77.4%). The development of the reproductive organs was estimated based on the fertility and viability of pollen grains, percentage of fruit and seed set. Pollen fertility ranged from 79.8% (of M. niedzwetzkyana) to 95.0% (M. × purpurea 'Ola'); its viability varied from 5.1% (M. niedzwetzkyana) to 51.5% (M. × floribunda). The highest fruit set percentages were recorded in M. floribunda (80.5%), while the lowest was in M. × purpurea 'Royalty' (16.4%). The average percentage of seed sets was 48.5%. The development of the reproductive organs of Malus specimens depended on their drought resistance. The fruit and seed set percentages had a strong negative correlation with the water deficit in leaves determined during the period of drought stress. The percentage of fruit set was also strongly correlated with relative turgidity. The leaf water deficit and relative turgidity were the most important physiological indicators in the drought resistance study, taking into account the need to maintain crop yield and the decorative effect of Malus plants.

THE STRUCTURE OF LANDSCAPE GARDENING LANDSCAPES IN CENTRAL EUROPE

Structurality is one of the important peculiarities of landscapes of different genesis and levels of organization. The structure of the landscape determines its physiognomic organization, shape, spatial and structural features. Garden and park landscapes are examples of constructive territory planning, cultural or «soft» use of natural conditions and resources, organization of supplementary interaction between man and nature. Therefore, the study of the structure of garden and park landscapes of Central Europe is an actual scientific problem. The aim of the article: to research the structure of garden and park landscapes of Central Europe. Studies of the structure of garden and park landscapes of Central Europe have been based on the principle of natural-anthropogenic coexistence. General scientific and specific scientific research methods have been used, namely: on the basis of expeditionary methods maps of the landscape structure of garden and park landscapes of the study area have been constructed. Spatial structure models have been built in the Corel Draw program based on the digitized surface of the planet Earth in the Google Earth program, vertical profiles of the relief of garden and park landscapes have been done with the help of Google Earth Pro tools. Studies of the daily state of garden and park landscapes have been carried out according to the generally accepted method of performing microclimatic observations. The article presents maps of the landscape structure and spatial configurations of the following garden and park landscapes: Pechersky Park (Pechera village, Tulchynsky District, Vinnytsia Oblast, Ukraine), Sokilets Park (Sokilets Village, Vinnytsia District, Vinnytsia Oblast, Ukraine), park Arcadia (Nieborow, Lod Voivodeship, Poland). Vertical relief profiles have been constructed. The temporal structure of changes in the state of garden and park landscapes in the research area have been studied using the example of the garden and park landscape of the Sofiivka National Dendrological Park of the National Academy of Sciences of Ukraine (Uman, Cherkasy Oblast, Ukraine).

THE BUCF HERBARIUM DATABASE OF ALLOCHTHONOUS OAKS

The BUCF Herbarium stores 253 specimens of allochthonous oaks species belonging to 33 accepted taxa. Amongst the representatives, Quercus rubra has the most recordings. Moreover, three species classed as near threatened on the IUCN Red List were identified. The most significant contribution was made by the botanist S. Pașcovschi who amassed approximately one-third of the collection. The specimens were collected between 1872 and 1987, with a maximum activity between 1940 and 1949. The majority of the specimens were sampled from dendrological parks and botanical gardens in Romania, the Bazos Dendrological Park remarking itself with one of the most diverse collections of cultivated oaks. A considerable number of specimens were received from donations and exchanges with several herbaria. Most of the herbarium material is very well-preserved having high potential for future investigations.

RUSSIAN-UKRAINIAN WAR: ENVIRONMENTAL ASPECT

According to the results of the study of the nature protection aspect of the russian-Ukrainian war, it was established that since 2014, the russian federation illegally captured and destroyed about 500 objects of the nature reserve fund of Ukraine, with a total area of over 1.2 million hectares. Came under occupation 3 Biosphere Reserves, 14 Nature Reserves, 19 National Natural Parks, dozens Regional Landscape Parks, hundreds Reserves, Sights Nature, Reserve Tracts, Botanical gardens, Dendrological parks, Zoological parks and Parks-sights of garden and park art. Famous protected objects suffered from russian military aggression: Biosphere Reserve «Askania-Nova», Chornomorskyi Biosphere Reserve, National Natural Parks «Slobozhanskyi», «Gomilshan Lisy», «Svyati Hory», «Meotida», «Oleshkivsʹki Pisky», Nature Reserve «Khomutovsky Step». Practically all types of biodiversity in the protected areas have been destroyed, unique landscapes are disturbed, the scientific achievements of specialists of nature-reserved objects were liquidated or exported. Cases of mining of protected areas have been recorded, uncontrolled deforestation, destruction of rare species of flora and fauna, etc.
 At the first stage of military aggression, in 2014, russia illegally occupied 100% of the natural reserve fund of the Crimean peninsula, 25.2% of the nature reserve fund of Donetsk region and 23.8% of the nature reserve fund of Luhansk region. In the second stage of aggression and full-scale war against Ukraine, from February 24, 2022, the russian federation completely seized all territories and objects of the nature reserve fund of Donetsk and Luhansk regions, as well as a significant part of valuable nature conservation of Kyiv, Sumy, Chernihiv, Kharkiv, Zaporizhzhia, and Kherson regions. As of September 1, 2022, a large part of the territory of Ukraine, including nature conservation areas, is freed from occupation. But it is still quite difficult to assess the damage caused to the national nature reserve fund. Therefore, the prospect of further scientific-practical research remains the assessment of damage caused to protected objects and territories in the east and south of Ukraine.
 Key words: war, russian aggression, national natural parks, nature reserves, biosphere reserves, flora, fauna.

Determination of the species structure of phytocenoses of the natural age oak forest of the Dendrological Park "Olexandria" of the National Academy of Sciences of Ukraine

The modern species composition of woody plants of the centuries-old oak grove of the State Dendrological Park "Olexandria" of the National Academy of Sciences of Ukraine was studied.
 The work was carried out as part of the study of the dynamics of stands of oak phytocenoses under conditions of anthropogenic load, technogenic pollution and weather fluctuations.
 It has been established that the oak grove of the arboretum with an area of 446 hectares out of 2000 oaks is a complex multi-species planting. The floristic core of the oak forest consists of the main forest-forming species characteristic of the Right-Bank Forest-Steppe of Ukraine: Quercus robur, Acer platanoides L. and Acer campestre L., Fraxinus excelsior L., Tilia cordata Mill., Carpinus betulus L., Ulmus scabra Mill. The role of the dominant species and edificator was retained by Quercus robur. In the worst growing conditions, monodominant stands are formed. In more favorable ecotopes in the upper tree layer, the participation of Quercus robur is 70–100 %, and its codominant satellites (Acer platanoides, Tilia cordata, Fraxinus excelsior) are 10 % each. All oak forest phytocenoses have a well-developed multi-species second tree layer: Acer platanoides (15–80 % in various phytocenoses), Acer campestre (10–30 %), Tilia cordata (10–60 %), in some phytocenoses Fraxinus excelsior (10–20 %), Ulmus scabra (10–20 %), Carpinus betulus (30 %).
 The group of asectators is diverse and is represented by small species, local and adventive species, introducers, including invasive species.
 A characteristic feature of the oak forest is its exorbitant crushing, which, along with the massive introduction of introduced species, caused a powerful ecotonization of the oak forest and formed the cells of the greatest mortality of Quercus robur.
 The conducted studies establish the modern species composition of the oak forest and are the basis for the study of succession processes in oak forest phytocenoses.

За допомогоюнаборів геопросторових продуктів досліджено динаміку змін площі лісу тапосівних угідь за різними видами природно-заповідного фонду України за2000–2020 рр. Найбільшу частку ліси займають в заповідних урочищах,парках-пам’ятках садово-паркового мистецтва та дендрологічних парках(більше 73 % лісів), з яких найбільші зміни відбулися в заповідних урочищах на 1,81 % площ (1,7 тис. га) та дендрологічних парках — на 1,02 %площ (17 га). Дослідження та результати показали, що в цілому на національному рівні зміни з часом не суттєві (до 3 % для лісів і до 2 % длясільськогосподарських площ), однак вони мають велике значення,оскільки природні ресурси обмежені, а якість життя людства залежитьнасамперед від природи, екології та якості навколишнього середовища.
