The prospects of a model exposition in artificial plantations in urbanized territories

The main tasks of the ecological potential are to unite the disparate existing elements of plantings and supplement them with new ones. The assimilation of unique plant ecosystems is possible with an integrated approach. The Volgograd region belongs to the dry-steppe zone, the climate is sharply continental, for which the characteristic features are a decrease in natural moisture supply, excess heat, an active wind regime throughout the year and frequent dry winds. The ecological potential of the south of Russia, in particular the Volgograd region, according to the climate Biological efficiency Index (TC) proposed by N.N. Ivanov, is at a low level (TC = 8–12) with unfavorable natural living conditions of the population with a significant lack of moisture, which raises the question of creating multifunctional plantings as a research scientific basis for rational regional environmental policy in optimizing the process of settlement and social sphere, consistent organization of work and recreation, protection of citizensʼ health. Dendrological expositions growing on cadastral plots of the Federal Research Center for Agroecology of the Russian Academy of Sciences have a high ecological potential in urbanized territories.The purpose of the study is to evaluate the prospects of a model exposure of drought–resistant species in artificial plantings.A general analysis of the decorativeness of G Gleditsia triacanthos f. inermis, Rosa canina, Ribes aureum, Ligustrum vulgare, Juniperus sabina was carried out, the variability of the total assessment of decorativeness between species (34.2–36.6) and the total score (177) were established. All the studied species have good drought resistance, which helps the woody plant to use water and nutrients most efficiently in arid regions on chestnut soils with low moisture supply.

Anthracnose of stone fruits, caused by species of the genus &lt;i&gt;Colletotrichum&lt;/i&gt;

Fungi from the genus Colletotrichum in the Moscow region affect the main stone fruit crops. In the Lipetsk region and the Republic of Mari-El, these pathogens were noted on cherries. The most affected crop is cherry, which in some years can lose 50-70 % of fruits from anthracnose. Varieties Apukhtinskaya and Rusinka were the most heavily affected by anthracnose. On plum and plum-cherry, the symptoms of anthracnose appear later than on cherry and sweet cherry. The appearance of symptoms is associated with the maturation of these cultures. On the plum, infection of the ovaries with Colletotrichum spp. can also inhibit the development of fruits, and their abscission, especially if the infection of fruits occurs in conjunction with other pathogenic fungi. Molecular genetic analysis of two cultures of Colletotrichum isolated from cherry fruits showed that the cultures belong to two species. These are Colletotrichum fioriniae and Colletotrichum godetiae. Artificial infection of green plum fruits in laboratory conditions showed that two isolates of Colletotrichum sp. godetiae isolated from golden currant and cherry fruits successfully infect green plum fruits. The most effective for infection is the method of infection in the puncture of the skin of the fetus.

Influence of abiotic environmental factors on the biochemical composition of crop production fruits

The article provides information on the study of the effect of abiotic environmental factors on the quality of fruit and berry and medicinal plants in Volgograd and the region: Carthamus tinctorius L., Ribes aureum Pursh., Rosa rugosa Thunb., Rosa cinnamomea L., Rosa acicularis Lindl., Rosa spinosissima L., Rosa canina L. The studies conducted by the authors make it possible to assess the natural and climatic conditions of the region, as well as the suitability and safety of plant species, which is relevant from the point of view of improving the quality of life and improving the health of the population, as well as the development of crop production. The results of the experiments allowed us to recommend certain types of rosehip, safflower and currant for the production of plant products and use in medicine. During laboratory tests, the content of lead, cadmium, zinc and copper was found in the fruits of experimental plants. The maximum fat content in 1000 g of safflower seeds is achieved by applying a dose of sewage sludge of 10 t/ha with a seeding rate of 250 thousand pieces/ha. it was found out that the content of amino acids in fruit bushes depends on weather conditions – 2020 showed an increase in arginine, glycine, leucine and isoleucine in golden currant, proline in rose hips, which indicates their high drought resistance. It was revealed that the content of zinc (12 mg) and copper (8 mg) increased in the fruits of golden currant in areas located close to highways, which is why the collection of fruits for eating in these areas is not recommended. The characteristics of irrigation norms for species at different heights of the aboveground part are given.

Влияние полезащитных лесных насаждений на микроклимат агроландшафта в сухостепной зоне каштановых почв

The article presents the results of correlation and regression analysis of the interrelationships of microclimatic indicators and the distance from the forest strip. Field studies were conducted in the dry-steppe zone of chestnut soils during 2020–2021 in the summer, autumn, and winter periods. The object of the study is a fortyyear old protective forest strip of openwork construction of the Kachalinskoye experimental-production farm of mixed breed composition of small-leaved elm (Ulmus parvifolia J.) and golden currant (Ribes aureum P.) along the edges of the strip. In the course of the analysis, various degrees of dependence of the studied factors on each other were revealed. Correlation analysis revealed a positive relationship (on the Cheddock scale) between the distance from the forest strip and wind speed (r = 0.94–0.96), humidity (r = 0.83–0.86), and air temperature (r = 0.80–0.89). The average and strong correlation between microclimatic indicators and the distance from the forest strip is noted in part of the measurements for soil humidity and temperature. The obtained regression models and determination coefficients indicate the proximity of the mathematical model to empirical observations.

Testing of moisture-saturating polymers and synthetic mulching materials for growing fruit and berry crops

The article studies the growth and development of red raspberry (Rubus idaelus L.), Nanjing cherry (Prunus tomentosa Thunb.), golden currants (Ribes aureum Pursh.), and sea buckthorn (Hippophaerhamnoides L.) in the variants of the experiment polymer gel + film + additional wetting by rainwater and meltwater runoff; polymer gel + film; polymer gel; control (without polymer gel and film). It was established that the use of a mulching black film could increase the moisture content of the root zone by up to 40%. When determining the water deficit, it was found that the experimental plants lost less moisture. Under the influence of hydrogels, the irrigation depth of fruit and berry crops was reduced by 50%. It was found that the black mulch film had a warming effect on the soil, which also had a positive effect on plant growth and development increasing the root zone temperature. Red raspberry bushes formed better when using hydrogels in the soil; during seasonal observations, an increased number of first-year canes was noted up to 2.5 higher than in the control. The hydrogel and mulching film had the best effect on Nanjing cherries, increasing the number of leaves on experimental plants and formed fruit shoots. Sea buckthorn under the film exceeded biometric indicators by 2 times vs the control plants. In golden currant plants, the best growth and development were observed in the variant using hydrogel and mulching film; foundation stocks developed intensively and bore fruit better with the experiment continuation, it is possible to obtain high profits from the sale of grown products. The use of hydrogels and mulch film reduces herbicide costs by reducing weeds and producing organic fruits and berries.

EVALUATION OF THE AMINO ACID AND BIOCHEMICAL COMPOSITION OF FRUITS OF ROSA L. AND RIBES AUREUM PURSH. SPECIES IN ARID ZONE

The article presents the data of the biochemical composition of the fruits of wild roses species, laboratory studies of which were conducted for the first time in Volgograd. Special attention is paid to the fact that wild roses is the one of the most important genera in the world and has an economic value in the biological, floriculture, pharmaceutical and cosmetic industries. It has been established that the difficulties of seed propagation of wild roses in arid conditions are primarily related to the peculiarities of their physiology, biochemistry and morphology. The objects of research were species with different areas of natural distribution: R. rugosa Thunb., R. cinnamomea L., R. spinosissima L., R. canina L., Ribes aureum Pursh., growing in collection areas of the Federal Research Centre for Agroecology, Complex Reclamation and Protective Afforestation. The article analyzes the indicators of weather conditions. The degree of demand for soil fertility and light revealed the most low-demand species: R. aureum, R. cinnamomea, R. rugosa and R. spinosissima. The authors found that all the studied species had good growth and development during the observation period. The amino acid composition of wild roses and currant fruits was determined using the capillary electrophoresis system "Drops" at a wavelength of 250 nm and allowed us to identify the most valuable species in terms of their biochemical composition. Analysis of the biochemical value of fruits found that the highest amount of protein, calcium, raw fiber, iodine and phosphorus differs type R. cinnamomea from the section of high-vitamin species and R. canina.

Structural and functional characteristics of the leaves of economically valuable plants in arid environments ​

The difficult forest conditions of the Volgograd region determine the relevance of research in the field of agroforestry. For the selection and use of tree species in plantations during the arrangement of agricultural land, it is necessary to identify the structural and functional features of the leaves, which are reliable indicators of the mechanism of plant adaptation to stress factors. The experiment was set up during June to September 2022 under field and laboratory conditions with the participation of the dendrological collections of the Nizhnevolzhskaya station for tree species breeding, a branch of the Federal Scientific Center for Agroecology of the Russian Academy of Sciences (50°078ʹN, 45°370ʹE). The objects of research are shrubs of different geographical origin: Berberis vulgaris L., Berberis heteropoda Schrenk., Ligustrum vulgare L., Cotinus coggygria Scop., Mahonia aquifolium Nutt., Corylus avellana L. and Ribes aureum Pursh. An optical method was used to assess the permeability of the epidermis of native mature leaves of the middle tier of the crown. The dynamics and variation of the content of photosynthetic pigments has been established. In Ligustrum vulgare, Mahonia aquifolium and Cotinus coggygria, a higher content of chlorophylls and a smaller number of palisade mesophyll cells were found than in heliophytes. The species specificity of the structural features of the palisade mesophyll, taking into account the ecological groups of shrubs, was revealed, as well as a positive correlation between the number of cells and the amount of chlorophyll of the palisade mesophyll in Cotinus coggygria (0.87) and Ribes aureum (0.85), Corylus avellana (0.63). The conducted studies allow obtaining new data on the adaptive capabilities of shrubs under the action of stress factors for their selection and further practical application in the field of agroforestry.

РОСТ, СОСТОЯНИЕ И ПРОДУКТИВНОСТЬ КУСТАРНИКОВЫХ ПОРОД В УСЛОВИЯХ ОТВАЛОВ ЖЕЛЕЗОРУДНЫХ МЕСТОРОЖДЕНИЙ

Various types of vegetation were tested on the dumps of the Kursk magnetic anomaly (KMA), composed of various rocks and their mixtures, with the improvement of forest growing conditions by land use and without this technique, including five types of shrubby species: sea buckthorn (Hippophae rhamnoides L.), siberian peashrub (Caragana arborescens Lam.), golden currant (Ribes aureum Pursh.), tatarian honeysuckle (Lonicera tatarica L.) and red elderberry (Sambucus racemosa L.). Growth indicators, safety and productivity of breeds were studied. Golden currant was one of the first to be tested, which turned out to be an unsuitable breed for creating protective plantings on dumps without measures to improve their forest growing conditions. On chalk-marl mixtures and quaternary loams, it completely fell out by the age of 12-15 years. Shrubs used in forest reclamation on two-component post-technogenic areas are characterized by different preservation. By the age of 43, the greatest preservation, equal to 50.5%, was noted in the sea buckthorn. It also has the highest growth rates. When choosing shrub species for forest reclamation, it is necessary to take into account their biological productivity, which increases the concentration of nutrients in the substrates and improves their physical properties. The sea buckthorn at the age of 9 has a large phytomass (2368 g), the heaviest leaf mass (396 g) and a total supply of phytomass (143.9 kg /ha) in the stand. The authors recommend using shrub species for laying preliminary crops at the initial stage of reclamation or introducing them into complex plantings in an amount of no more than 50%. Taking into account the soil-improving role of shrub species, it would be advisable to further introduce more durable tree species.

АНАЛИЗ ПОРОДНОГО СОСТАВА КУСТАРНИКОВ В ГПКИО ИМ. М.ГОРЬКОГО И ПАРКЕ ПОБЕДЫ

The article provides an analysis of the state and assortment of existing shrubby vegetation in the City Park of Culture and Recreation named after. Gorky and Victory Park, Saratov. Green spaces perform a number of important environmental functions: reducing noise, gas pollution and dustiness of the air, enrichment with oxygen and phytoncides, improving microclimatic indicators, etc. When classifying green spaces, the approaches outlined in the work of T.G. Guzenko were used. During the survey of plantings, the species affiliation of shrubs was established, the Latin names of species are given according to S.K Cherepanov. The species diversity on the presented objects is quite high. To improve the living condition of shrubby vegetation, it is necessary to additionally reconstruct or create a hedge around the perimeter of landscaping facilities, which will isolate the indoor air environment of plantings from various pollutants. The most promising species for increasing the share of shrubs in the park can be considered Mahonia aquifolium Nutt, Symphoricarpos albus L., Córnus álba, Lonícera caprifólium L., Juniperus media P.J. van Melle, Ribes aureum Pursh, Philadelphus coronarius L., Syringa vulgaris L., which have proven themselves well in these environmental conditions. Particular attention should be paid to the introduction of coniferous species such as, Thúja occidentális L., Juniperus scopulorum Sarg., Juniperus media P.J. van Melle into plantings.

Morpho-biological features of growth and development of golden currant in Tashkent province, Uzbekistan

This scientific article presents the results of a study on the growth and development of varieties of golden currant in order to identify the most promising for cultivation in the conditions of the Tashkent region. Studies have established that, according to the development of shoots in the above-ground part, the varieties Uzbekistanskaya large-fruited and Elixir differ in vigorous growth, in which the height of the bushes by the end of the second year of vegetation reached 109.7-112.5, and in other varieties this figure was in the range of 88.2-97.5 cm. Of the tested varieties of golden currant, the earliest onset of the flowering phase was observed in the Venera variety March 23, in the rest a little later. The variety of golden currant Rukhshona had the latest start of flowering, in which this phase occurred on March 26, that is, four days later. In the Uzbekistan large-fruited variety, the completion of the flowering phase occurred five days later than in the Uzbek sweet variety. Of the varieties of golden currant, the phase of complete set of berries was observed most intensively within 30 days in the variety Venera. In the Elixir variety, the full set of berries ended two days later, and in the rest within 34-36 days.

Assessment of economic and biological signs of Ribes aureum Pursh. forms in the conditions of the Orenburg region

Over the past 20 years, research on the study and preservation of unique forms, varieties and genotypes of golden currant plants has been of particular relevance. The article presents the results of studying 10 forms of golden currant in terms of drought resistance, productivity and biochemical parameters. The research was carried out in 2018-2021 on the basis of the Orenburg branch of the Federal State Budgetary Research Center of Horticulture. The forms of golden currant 2009 planting were used as objects of research: 1-1, 1-2, 1-3, 1-4, 1-5, 1-6, 2-1, 2-2, 2-3, 2-6. Planting scheme is 3.0 ? 2.0 m. The purpose of the research was to study the gene pool of golden currant and identify promising forms with a complex of economically valuable traits. It was found that forms 1-1 (6.7 kg/bush), 1-2 (7.1 kg/bush), 1-3 (7.9 kg/bush), 2-2 (6,3-5,9 kg/bush), 2-6 (6,4-6,0 kg/bush) are characterized by high productivity. The highest average berry weight was observed in forms 1-1 (2.22 - 1.92 g) and 2-6 (2.46 - 2.33 g). Taking into account the complex of indicators (drought resistance, the number of berries in the brush, the average weight of berries, productivity, ascorbic acid, sugar), the most promising forms of golden currant 1-1, 1-3, 2-6 were identified. They can be recommended for the conditions of the Orenburg region.

Состояние древесных растений на объектах защитного лесоразведения и озеленения Калачевского района Волгоградской области

The Kalachevsky district of the Volgograd region belongs to the regions that require stabilization of natural resources use. Land and forest reclamation and landscaping will ensure the resource potential of the district’s landscapes at increasing recreational and natural load. The studies have shown that differences in inventory parameters, development, fruiting and sustainability of plants are due to soil and climatic conditions, and anthropogenic impact. The research objects are woody species, predominantly of European habitats: sweet chestnut – Castanea sativa Mill.; Pallas pine (Crimean pine) – Pinus pallasiana D. Don.; European crab apple – Malus sylvéstris Mill.; white poplar (silver poplar) – Populus alba L.; white willow – Salix alba L.; English oak – Quercus robur L.; European ash – Fraxinus excelsior L.; Lombardy poplar – Populus nigra var. italica Münchh.; wych elm – Ulmus glabra Huds.; golden currant – Ribes aureum Pursh.; common lilac – Syringa vulgaris L.; Russian pea shrub – Caragana frutex (L.) K. Koch; common privet – Ligustrum vilgare L.; Oregon grape – Mahonia aquifolium (Pursh.) Nutt.; cinnamon rose – Rosa cinnamomea L. It was found that relatively stable species in the Kalachevsky district are European crab apple, golden currant (which has the best salinity resistance), Russian pea shrub, wych elm, Oregon grape, but they are inferior to poplars, willows, lilacs, chestnuts in inventory parameters and growth rate. The best performance on a number of economically valuable features were observed in chestnut, spruce, apple, poplar, willow, elm, ash, and rose. Chestnut, currant, Oregon grape, lilac, privet, cinnamon rose have the highest score of ornamentality for landscaping plantations. Chestnut, rose, and oak have the best fruiting rates; ash and privet have medium fruiting rates. The strongest stage of recreational digression is observed in areas remote from settlements: there is densification of plantings, lack of sanitary cuttings, medium passability. Areas near water sources, as well as public gardens and parks, require sanitary care, reduction of recreational pressure and the selection of species from the recommended range of trees and shrubs. In order to ensure the greatest sustainability of plantings and obtain a rapid silvicultural effect, perennial, fast-growing species as well as fruit shrubs recommended in the basic assortment should be included in the protective and landscaping plantations of the arid region.

Growth, Development and Yield of Golden Currant (Ribes Aureum Pursh.) Depending on Cultivation System

Abstract Although golden currant has been grown in Latvia for several decades, mainly as ornamental plant, there is little experience on the most suitable cultivation systems for berry production. Two cultivars of golden currant — ‘Laila’ and ‘Uzbekistanskaya Krupnoplodnaya’, were planted in 2017 in two cultivation systems — vertical trellis and shrub form and assessed in the first two seasons with harvest. In addition, plots with and without organic mulch were established in the shrub system. The aim of the study was to investigate the growth, development and yield of golden currant depending on the cultivation system. All plants bloomed abundantly and practically at the same time in both years, while no significant differences were found between cultivation systems and cultivars. The annual growth of shoots in 2020 was significantly affected by the cultivation system — on average 0.66 m in the trellis system, 0.41 m in the shrub system in mulched plots, and 0.43 m in unmulched plots. Cultivar ‘Laila’ tended to produce longer shoots (average 0.51 m) than the ‘Uzbekistanskaya Krupnoplodnaya’ (average 0.47 m). The yield was low because of poor fruit set and did not significantly differ between cultivar and cultivation systems, though cultivar ‘Laila’ and shrub systems still had higher yields.

Genetic structure of a Ribes genetic resource collection: inter- and intra- specific diversity revealed by chloroplast DNA simple sequence repeats (cpSSRs)

Currants and gooseberries (Ribes sp.) are important berry crops with high nutritional value, and the efficient development of new cultivars depends on the characterisation of Ribes genetic resources and successful inclusion into breeding materials. Ribes breeding programs are characterised by the extensive use of interspecific crosses to introduce required traits. In some cases, this makes it challenging to identify the genomic contribution of particular species to cultivars, thus limiting the understanding of the heredity of these traits. To clarify these issues, the present study aimed to evaluate the applicability of selected chloroplast SSR molecular markers to analyse germplasm consisting of genotypes developed through complicated multistage crosses among different Ribes species. This provides information on Ribes germplasm species composition and blackcurrant collection species structure, thus assessing the applicability and utility of the blackcurrant collection in breeding. Fifty cpSSR molecular markers previously developed for plants were assessed, and a set of 19 markers was selected for further analysis of a Ribes genetic resource collection. A set of 145 Ribes genotypes was analysed using the selected chloroplast markers: blackcurrants (R. nigrum L.), redcurrant (R. rubrum L.), European gooseberry (R. uva-crispa L.), mountain currant (R. alpinum L.), golden currant (R. aureum Pursh), R. americanum Mill., jostaberry (R. × nidigrolaria Rud.Bauer & A.Bauer), R. ussuriense Jancz., R. komarovii Pojark., R. sanguineum Pursh., R. latifolium Jancz., R. fasciculatum var. chinense Maxim., R. fragrans Pall., R. laxiflorum Pursh. and their interspecific hybrids. The cpSSR markers are suitable for differentiating Ribes species and thus are suitable for analysing germplasm collections, showing relationships regarding pedigree. The markers are good at showing the structure of a germplasm collection. However, in the case of complex interspecies crossings, identifying a specific percentage of a species within an accession cannot be guaranteed.

АНАЛИЗ ЖИЗНЕСПОСОБНОСТИ ДРЕВЕСНЫХ ВИДОВ В ЗАЩИТНЫХ ЛЕСНЫХ ПОЛОСАХ АРИДНОЙ ТЕРРИТОРИИ ВОЛГОГРАДСКОЙ ОБЛАСТИ

To solve scientific and practical problems in the field of agroforestry of arid territories, it is particularly relevant to preserve protective forest plantations of artificial origin on agricultural lands, since they have a positive impact on the yield of agricultural crops. Increasing the resistance of tree plantations to unfavorable natural and climatic factors of the arid zone, increasing the period of the reclamation effect on soil fertility, improving the ecological state of agrarian landscapes is a priority task in agroforestry reclamation measures. Created in the middle of the XX century, without deep analysis of soil and geological conditions, without taking into account salt resistance and proper care for a long time, forest strips began to degrade and lost their basic functionality. Intended primarily to mitigate the harsh climate of the Volgograd region, forest strips have also lost their aesthetic appeal. Taking into account the considerable experience of artificial afforestation in the arid zone and in the conditions of the dry steppe, there is still no clear scientific justification for the creation of sustainable protective forest plantations that can provide an appropriate reclamation effect aimed at reducing wind speed, improving the microclimate of fields and stabilizing water and wind erosion. In order for agroforestry in the region to have the calculated effect, an analysis of tree plantations in protective forest strips was carried out, since it is necessary to improve the range of tree and shrub plantations that are used in the creation of artificial forest plantations. The heat resistance and winter hardiness of seeds of the most common tree plantations (such as Quercus robur, Ulmus pumila, гибриды вязов, Ulmus minor, Robinia pseudoacacia, Fraxinus lanceolata, Caragana arborescens, Ribes aureum, Tamarix ramosissima) were studied, their salt resistance and durability of the seed generation were studied. Based on the results obtained it was concluded that the most promising for protective afforestation are such genera as: Ulmus pumila, Ulmus pumila x carpinifolia, Ulmus carpinifolia, Robinia pseudoacacia, Celtis occidentalis и Caragana arborescens, the breeding efficiency of which has been proved by the general condition of many protective forest plantations and their resistance in the arid region.

DESICCATION OF CURRANTS AND GOOSEBERRY BRANCHES CAUSED BY FUNGI OF THE GENUS CYTOSPORA IN CENTRAL RUSSIA

Research carried out in 2019-2020 in four regions of central Russia, showed that three species of fungi from the genus Cytospora (Cytospora ambiens, C. grossularia and C. ribes) are found on the desiccating branches of black currants, red currants, golden currants, and gooseberries. In the Moscow region, two species have been marked: C. grossularia and C. ribes. The species Cytospora ribes was the most widespread. In the Yaroslavl region, 3 species of the genus Cytospora were mentioned on black currants, red currants, and gooseberries, these are Cytospora ambiens, C. grossularia and C. ribes. The fungus C. ambiens on red currants was found twice as often (33.3 %) than C. ribes (16.7 %). In the Bryansk region, the fungus Cytospora ambiens was revealed from the desiccated branches of black currant. The fungus Cytospora ribes was identified from plant samples of black currants taken at the Fruit station of the Timiryazev Agricultural Academy (Moscow), and from the gooseberry C. grossularia. Currant infect ability records of currants and gooseberry to cytosporous desiccation showed that the most affected by Cytospora spp. there was golden currant with an average score of 1.32, and gooseberries were the least affected crop with an average score of 0.32.

Укрепление и защита берегов в Калачевском районе Волгоградской области с помощью кустарниковой растительности

The critical abrasion situation manifests itself on the coastal part of the Kalachevsky district due to the increasing anthropogenic load. The most important element of the complex of measures to combat silting of reservoirs and coastal abrasion, as well as an effective measure to strengthen the banks is forest vegetation. The objectives of the research were to study the soil, forest and climatic conditions of the object under study, to develop an assortment of shrubs and features of the formation of protective forest stands, as well as criteria for selecting an adapted assortment of tree and shrub vegetation and methods of caring for the soil and plantings. During the research, the most promising types of shrubs for creating upper protective forest stands were identified: Ligustrum vilgare L., Berberis vulgaris L., Cotoneaster lucidus Schltdl., Amelanchier Medik., Ribes aureum Pursh., Rosa canina L. It was found that the useful role of forest stands is manifested in their ability to convert surface runoff into subsurface runoff, to clean surface stock water from fine-grained soil, to weaken the speed of movement and to extinguish the energy of waves, binding the soil with roots. Recommendations are given for the creation and placement of anti-abrasion plantings, depending on the steepness and height of the slope. It is stated that one of the main measures for the care of the aboveground part of the plantings is the pruning of the crown, carried out taking into account the biological characteristics of their growth and development, including the removal of dry and damaged branches, thinning of the crown, preservation of the previously given crown size, rejuvenation of the crown. It is recommended to place shrubs depending on the landscape, soil and climatic conditions and features of abrasive processes in areas of constant, periodic, episodic flooding and strong moderate and weak flooding of the coastline.
