Abstract:

The flora in the vicinities of Arapya Bay, Alepu beach, Sinemorets and Silistar cape of the Bulgarian Black Sea coast (which includes three beach zones and two protected natural areas) is rich in rare psammophytic and halophytic species: Hypecoum ponticum Velen., Pancratium maritimum L., Silene thymifolia Sm., Eryngium maritimum L., Limonium latifolium (Sm.) Kuntze, Tulipa thracica Davidov, Centaurea arenaria M. Bieb., Trachomitum venetum (L.) Woodson and Maresia nana (DC.) Batt. Within these areas some Mediterranean geo elements reach their northernmost point: Reichardia picroides (L.) Roth and Romulea linaresii Parl. All of the species mentioned above have been included in the Red List of Bulgarian vascular plants (1) The Tulipa thracica Davidov species fall under a Critically Endangered (CR) category. Nine species have an Endangered (EN) status: Hypecoum ponticum Velen., Pancratium maritimum L., Silene thymifolia Sm., Eryngium maritimum L., Trachomitum venetun (L.) Woodson, Reichardia picroides (L.) Roth, Cistus salviifolius L., Verbascum bugulifolium Lam. and Serapias vomeracea (Burm.) Briq. Six species fall under a Vulnerable (VU) category: Limonium latifolium (Sm.) Kuntze, Centaurea arenaria M. Bieb., Maresia nana (DC.) Batt. and Romulea linaresii Parl., Limodorum abortivum (L.) Schwarz and Orchis papilionacea L. Under a Least Concern (LC) are the following species: Fritillaria pontica Wahlenb. and Mespilus germanica L.

Abstract:

This article presents a detailed analysis of the taxonomic composition of the Pliocene (Kimmerian, Kujalnikian) and Eopleistocene (Gurian) ostracods in the northern part of the Black Sea. It presents the patterns of the stratigraphic position of the fossil ostracods in the Miocene - Quaternary and their geographic distribution in Western and Eastern Europe (the Pannonian Basin, the Dacian Basin, the Euxinian basin of the Paratethys) and the Mediterranean region.Wedetermined the characteristic species for the Kimmerian, Kujalnikian and Gurian in the northern part of the Black Sea. We established a change in the taxonomic composition of ostracods at the Pliocene (Kujalnikian)/Eopleistocene (Gurian) boundary, namely the disappearance of a large number of Pliocene species and the appearance of new species. Ten species disappeared in the Kujalnikian Cyprideis pontica, Euxinocythere (M.) crebra, Amnicythere mironovi, Camptocypria lobata, Loxoconcha subcrassula, Loxoconcha verticalitercostata, Xestoleberis (X.) cellulocus, Xestoleberis (P.) communis, Candona (C.) expressa, Ilyocypris caspiensis; one species Amnicythere postbissinuata appeared in the Gurian. The brackish water species Cyprideis pontica is the Kujalnikian index species. The stratigraphic position of Cyprideis pontica in the Mediterranean Basin, Pannonian Basin, Dacian Basin, Euxinian Basin (Black Sea) in the Miocene-Quaternary is analyzed. The time of the disappearance of Cyprideis pontica in the Mediterranean, Pannonian and Dacian basins (Messinian, Pontian/Zanclean, Dacian, Kimmerian boundary) and in the Black Sea (Kujalnikian/Gurian boundary) is established. The diagnostic morphological features of the shell Cyprideis pontica (morphology of the surface pore canals) are established and described, which allows us to place this species in the Neogene deposits. Surface pore canals are different shape, sievetyped, deepened in relation to the surface of the valve. Sieve-shaped lamella contains 110-270 internal pores. The internal pores have a staggered shape, the diameter of the osculum of the internal pore is 302-994 nm; diameter of the central pore is 977 nm-1.8 μm). The evolution of Cyprideis pontica, which was separated from the parent species Cyprideis torosa in the Late Miocene, was reconstructed. In the occupation of a new ecological niche with a reduced oxygen content in deeper water biotopes, in the process of adapting to the conditions of hypoxia and necessity of increasing the volume of water filtration, there was a restructuring of the morphology of the surface pore canals of the shell Cyprideis torosa. This involved an increase in the size of the sieve-shaped lamella, the number of internal pores in the sieve-shaped lamella and the size of the osculum of the inner pore. A new morphotype Cyprideis pontica was thus formed within the existing Parathetys-Mediterranean basins. It had a mosaic, ecologically isolated range that coincided geographically or overlapped with the range of the species Cyprideis torosa (sympatric evolutionary speciation). The range of Cyprideis pontica and the dynamics of its populations in the Euxinian Basin during the Sarmatian-Kujalnikian have been reconstructed.

Abstract:

A group of late-Archaic terracotta roof tiles with architectural design from Olbia Pontica is being analysed in the following. It is now possible to discuss the six variants of painted façade decorations, which include meander patterns with various alternating filling elements such as quadrats, checkerboards and rosettes. These decorative systems combined three-colour palettes, being successors of the Corinthian system of decorative tiles. The comparison of the Olbian pan tiles and antefix cover tiles with the actual collections from Histria, Borysthenes, Levke island and Apollonia Pontica shows the common direction of sacred architectural design spread widely among the Milesian daughter-colonies in the Western and North-Western parts of the Pontus. The single centre of fabrication of the terracotta details, Miletus, seems to be preferable, but the involvement of Samos in this process must also be taken into account. A stylistic analysis of the late-Archaic architectural terracotta from the Pontic centres demonstrates the variety of forms and details that allows for the discussion about a specially produced cargo of terracotta building materials for every colony in South Ionia.

Abstract:

A study of Pardosa pontica (Thorell, 1875) in Iran indicates two distinct morphospecies. A detailed comparison of these morphospecies and types of P. pontica reveals that populations from Mazandaran, Golestan and North Khorasan Provinces of Iran and Balkan Welaýaty of Turkmenistan belong to a newly described species, P. mirzakhaniae sp. n., and populations in western and easternmost Iran belong to P. pontica. Although the two morphospecies differ in colour, size and spination, no molecular differences in 16S rRNA and COI were detected.

Full text

Abstract:

Paederotella pontica is a Colchis tertiary relict species, regional narrow endemic to the Caucasus, representative of an oligotypic genus. The aim of this study was to determine dormancy-breaking requirements and develop seed germination protocol for P. pontica. Freshly matured seeds of P. pontica are morphophysiologically dormant (MPD). Mean length of seed is 820 μm, linear embryo is fully differentiated, on average 625 μm long. Penetration of tetrazolium salt indicates the permeability of seed coat and high percentage of vital seeds in capsules. Prior to root emergence, the E:S ratio increased from 0.76 to 0.9. Effects of warm and cold stratification and gibberellic acid (GA3) on embryo growth and seed germination were studied under laboratory conditions. Since cold stratification is the only requirement for the loss of MPD, the longest embryo growth occurred during this treatment and GA3 promoted MPD loss, we concluded that P. pontica seeds have intermediate complex MPD. Based on the treatment results a germination protocol is proposed: 1. Dry storage at 20°C, 2 months; 2. Cold-wet stratification at 3°C, 3 months; 3. Germination at 20/15°C day/night. Under developed conditions germination is fast, synchronous and yields to 80%.

Abstract:

The research aimed at verifi cation of fungi species colonizing phyllosphere of pontic azalea <em>Azalea pontica </em>L. and at comparison of the fungi species composition: – in the natural stand in the Kołacznia nature reserve, – in arboretum collections at Bolestraszyce and Rogów. 600 fragments of healthy, infected and fallen leaves of pontic azalea were collected for mycological analyses. The species forming the largest number of colonies identified from the healthy leaves were: <em>A. alternata</em>, <em>Ph. cyclaminis</em>, <em>E. nigrum</em>, <em>Ph. medicaginis </em>and <em>B. cinerea, </em>from infected leaves<em>: A. alternata</em>, <em>E. nigrum, Ph. cyclaminis</em>, <em>S. fi micola</em>, <em>T. viride </em>and <em>A. phaeospermum, </em>whereas: <em>E. nigrum</em>, <em>A. alternata</em>, <em>S. fi micola</em>, <em>Ph. cyclaminis and B. cinerea </em>were isolated from the fallen leaves, which indicates that a majority of fungi persistently colonize the leaves during vegetation period and damage them, which leads to defoliation. Colonization of pontic azalea phyllosphere in arboreta by more numerous fungi colonies and species than under conditions of natural sites evidences their increased pressure in the arboreta environment.

Abstract:

During 1996–1997 a systematic sampling programme was carried out in brackish coastal lakes and lagoons and in the delta of the River Po. In six of the nine collecting locations, 12 species of Gastrotricha were identified. One species, Chaetonotus ichthydioides, is new to science; another three species, the chaetonotidans Heterolepidoderma foliatum and the macrodasyidans Dendrodasys ponticus and Turbanella cf. pontica, and one macrodasyidan genus, Paradasys (P. subterraneus), were found in Italy for the first time. The unusual morphology of some of the species identified shows that Gastrotricha colonized brackish waters from both marine and freshwater habitats.

Abstract:

Abstract Based on new evidence, observations are offered on the importation of roof tiles from Sinope and Heraklea Pontica to the west Pontic poleis and the Thracian interior. The data indicate that the roof tiles of both Sinope and Heraklea were distributed mostly in the 4th century BC. Despite the intensive importation of products in Sinopean amphorae in later periods, there were no imports of roof tiles. The insignificant volume of the imports is still more remarkable bearing in mind the evidence of the widespread use of roof tiles. This decline in imports was most probably related to the emergence of large-scale local production and/or imports from other Black Sea poleis.

Abstract:

The foundation of Messambria Pontica has been debated for more than a century. Some questions still remain unanswered while some answers need revision due to the developments in research. Among these questions are the date of Messambria’s foundation, the composition of its ἄποικοι, the identity of its historical founder, the polis’ relations with local Thracian tribes, etc. Recent studies on various topics that concern these questions, including new archaeological evidence, provide some possible interpretations of already known sources. Generally speaking, these interpretations both challenge and confirm some of the ideas that have gained acceptance in the literature. Interpretations discussed in this article concern when the apoikia was founded, what the impact and nature of the ἔποικοι was, what the name of Messambria means, and what its larger tribal environment looked like based on the latest archaeological research.

Abstract:

Abstract:This article argues against the traditional dating of the attack of Prusias I of Bithynia on Heraclea Pontica to the 190s, that is to the time before the Apamean settlement (188). The following re-examination of the only surviving literary source to refer directly to this event (Photius’ excerpts of the history of Heraclea Pontica by Memnon), together with relevant information from several other literary and inscriptional texts, allows us to connect the attack of Prusias with the war between the Bithynian and Pergamene kingdoms, which would then be dated to c. 184–183. The other major conclusion presented is that this war had no direct relation to the outcome of the Apamean settlement, as has been the majority opinion.

Abstract:

The aim of this work is to determine the qualitative and quantitative characteristics of biologically active compounds of Artemisia pontica L. Definition prospects of medicinal herbal raw materials in the treatment of diseases. Materials and methods. Research material (Artemisia pontica L. herb) was collected in August 2019 in the Zaporizhzhia region, Ukraine. The tincture was obtained by maceration. So, the tincture was being extracted with methyl alcohol at room temperature for 10 days. The tincture was extracted with methyl alcohol at room temperature for 10 days according to the method of preparing tinctures. The study of the chemical composition of tincture of Artemisia pontica L. was carried out using gas chromatograph Agilent 7890B GC System (Agilent, Santa Clara, CA, USA) with mass spectrometric detector Agilent 5977 BGC/MSD (Agilent, Santa Clara, CA, USA) and chromatographic column DB-5ms (30 m × 250 mkm × 0.25 mkm). Results. 26 compounds were identified by analysis. Compounds such as n-hexadecanoic acid (16.71 %), 9,12,15-(Z,Z,Z)-octadecatrienoic acid (13.29 %), 2-(4a,8-dimethyl-7-oxo-1,2,3,4,4a,7-hexahydronaphthalen-2-yl)-propionic acid (8.80 %), 8-nitro-(1H)quinolin-4-ol-2-one (6.45 %) and neophytadiene (4.66 %) prevail in tincture. A literature review showed that n-hexadecanoic acid stimulates anti-inflammatory processes in human immune cells through TLR4 receptors, it has antitumor and antidiabetic activity and it also has anti-inflammatory effects. Derivatives of 9,12,15-(Z,Z,Z)-octadecatrienoic acid are used in diabetes therapy. 2-(4a,8-Dimethyl-7-oxo-1,2,3,4,4a,7-hexahydronaphthalen-2-yl)-propionic acid is an immunosuppressant and probably improves tissue insulin sensitivity. In addition, it is necessary to underline the presence of neophytadiene that has an anti-inflammatory effect. The presence of β-phellandrene provides insecticidal and eucalyptol anti-inflammatory effects. Conclusions. Considering the individual actions of the individual components, Artemisia pontica L. herb can be recommended for further research on its anti-inflammatory, antidiabetic, and antitumor effects.

Abstract:

Abstract Connections between Olbia Pontica and Sinope were firmly established by the 5th century BC. The quantity of Sinopean goods in Olbia was especially numerous in the last quarter of the 4th to the first third of the 3rd century BC. Tiles, louteria, amphorae containing wine and oil, and architectural terracottas were all imported from Sinope. These connections continued until the middle of the 1st century BC, when Olbia was destroyed by the Getae. They were renewed again in the 1st century AD and continued until the last quarter of the 4th century AD, when the settlement of Olbia came to an end.

Abstract:

Specimens of Pontic shad (Alosa pontica Eichwald, 1838) were collected during April and May of 2006 in the Danube River (rkm 863) just downstream of the Iron Gate (Djerdap) II dam. Twenty-eight scales and 30 vertebrae were prepared and given to five interpreters with fish aging experience of from 3 to 30 years and with shad aging experience of from 0 to 12 years. Interpreters with experience in shad age determination showed lower values for the index of average percent error (IAPE) and an index of coefficient of variation (ICV). In regard to within-interpreter reproducibility, no significant differences were found between scale and vertebrae as structure for age determination. The most experienced reader showed the lowest value for IAPE, while the least experienced reader showed the highest value for IAPE. The results of this work indicate that experience in age determination by particular structure had more impact on age determination precision than specificity of structure, scale or vertebra. More work is needed on adopting standard protocols that must include some sort of common interaction between responsible age readers.

Abstract:

Two aerobic, psychrohalotolerant, motile bacterial isolates, CK13T and CK16, isolated from sea-water samples collected off the subantarctic Kerguelen island, were characterized by using a polyphasic taxonomic approach. On the basis of 16S rRNA gene sequence data, the strains were 99·6 % similar and exhibited 93–97 % similarity with the seven recognized species of Marinomonas. The most closely related species were Marinomonas pontica and Marinomonas primoryensis, with 97 and 96 % similarity at the 16S rRNA gene sequence level, respectively. DNA–DNA hybridization values between strain CK13T and M. pontica and M. primoryensis were only 58 and 40 %, respectively. The major fatty acids present in strain CK13T were iso-C16 : 0, C16 : 0, C16 : 1 ω7c and C18 : 1 ω7c. The DNA G+C content of strain CK13T was 41·2 mol%. Phosphatidylethanolamine and phosphatidylglycerol were identified as the predominant phospholipids. All the above characteristics support the affiliation of strain CK13T to the genus Marinomonas. Phylogenetic analysis and phenotypic and genotypic distinctiveness confirmed that strains CK13T and CK16 are members of a novel species of the genus Marinomonas, for which the name Marinomonas polaris sp. nov. is proposed. The type strain is CK13T (=MTCC 6645T=DSM 16579T=JCM 12522T).

Abstract:

The results of studies of the content of polyphenolic compounds and their antioxidant activity in the Pontic hawthorn plant Crataegus pontica K.Koch., growing in the mountainous regions of the Tashkent region of the Republic of Uzbekistan are presented. The collection of raw materials took place in the spring at the beginning of October 2019 and at the end of April 2020. The conditions for the isolation of polyphenolic compounds were selected under various conditions. It was shown that the optimal content of polyphenols is extracted with 70% acetone, followed by fractionation of the aqueous residue with ethyl acetate and precipitation with hexane. It was shown that in the plants harvested in spring, the amount of polyphenols was 4.28%, and the collected volume was 2.6%, of the air-dry mass of the raw material. Chromatographic methods (BC and TLC) revealed that the composition of plant leaves collected in spring contains more polyphenols than those collected in autumn. This plant contains compounds belonging to the class of flavonols, phenolic acids and flavan-3-ols. Polyphenols were identified by rutin, quercetin, quercetin-3-O-β-galactoside, catechin, and gallic acid by BC and TLC methods. The antioxidant activity of the sum of polyphenolic compounds was studied in the model of lipid peroxidation (LPO) in rat liver mitochondria. It was found that polyphenols have a protective effect on mitochondria, a reduced damaging effect of Fe2+ / ascorbate and antioxidant activity depends on the concentration of the studied polyphenolic substances. The introduction of rutin into the incubation medium in 5 μM medium inhibits LPO processes by 32.0%, and at 10 μM – by 85.9% and in 20 μM – by 96.8%, compared with the control.

Abstract:

On the territory of Olbia, three areas reserved for the worship of the gods were studied at different times, and the traces of craft activity were found in each of them: in the Eastern and Western temenoses – bronze foundries, and in the Southern temenos the bronze foundry some time later was replaced by ceramics workshop. The possibility of horn processing workshop functioning on the territory of the Western temenos of Olbia in the 5th century BCE is analyzed in the paper. This assumption is based on the discovery of a number of processed antlers in one of the complexes (bothros № 9). The range of these artifacts is represented by wastes of horn primary splitting, blanks, and semi-finished produced items. In addition, fragmented remains of the bone processing process (primarily processed horn) were found in other objects and layers of the Western temenos. Of course, the most convincing argument in favor of the horn being processed in the Temenos area would be the founding of an object there that could be convincingly interpreted as a workshop. However, it cannot be localized; one can only assume that it should have been, like other industries, at the side. The relatively small amount of processed horn and bone does not allow us to say that the craft activity that took place in the temenos could not be a specialized bone-cutting craft, but it could not be a household production for self-consumption either. Most likely, its production volume was dictated by the needs of the sanctuary, rather than a wide range of consumers: so there could not be a large specialized bone-cutting workshop. In addition, we cannot exclude that the horn was processed by a multi-skilled craftsman who also worked with other materials (for example, wood), or was focused on the production of specific produced items, rather than on certain raw materials. Such opinions are also caused by the predominance of semi-finished onlay plates at different stages of the production process. Specialized bone processing workshops have not been found yet, not only in the temenos but also in other parts of Olbia. We know about only a few objects (Tyritake, Myrmekion, Chersonesus) in the Northern Black Sea region, which can be convincingly associated with bone processing craft, but not specialized in it. Based on the available sources, we can conclude that the bone processing activity in the poleis of the Northern Black Sea region in general, and Olbia in particular, did not have the characteristics of a specialized craft. It is possible that the craftsmen were specialized not in raw materials, but in types of produced items. This is evidenced by the finding of complex works of art, not all of which could be imported as goods from other places.

Abstract:

This paper is preliminary review of a small collection of graffiti from the latest excavations on the western outskirts of Olbia Pontica (the so-called «suburbs») in 2015—2020, and their introduction into scientific circulation. The excavations were conducted by the Olbia International Archaeological Expedition led by A. V. Bujskikh as the part of Ukrainian-German multidisciplinary project (co-directors A. V. Bujskikh and J. Fornasier). The researches on the suburbs were headed by A. G. Kuzmischev and J. Fornasier. Over six years of research in various cultural strata and in the fillings of half-dugouts, pits and other objects more than 50 graffiti have been found, inscribed mainly on the fragments of Attic black-lacquered tableware of the 5th—4th centuries BC. Emphasis is placed on determining the main types of inscriptions and their features. Regardless of the year and location of discovery they are divided into five groups: A. Abbreviated anthroponyms or individual words; B. Initials of proper names or one-letter marks; C. Graffiti on treated ostracons; D. Various digital signs and records; E. Graffiti of unclear meaning. The collection under study significantly supplemented the source base of the small epigraphy of the Olbia polis. However, no original, rare and to some extent important informative inscriptions which were recorded in temenos, residential neighborhoods, in some settlements and in Borisfen have been found yet here. In addition the damage of many graffiti makes impossible to interpret them reliably. In no one case we could identify reliably the inscriptions dedicated to any deities. Instead, the large number of abbreviated names and initials of the owners of dishes coincides with a significant import of Attic black-lacquered ceramics in the life of the inhabitants of the suburbs in the 5th—4th centuries BC. Despite the relatively limited number, processed ostracons have replenished this category of Olbia votive finds by the original graffiti of magical significance. At the same time, the fact that in general in the suburbs is a lot of graffiti with digital markings which are most often attributed to traders, deserves special attention. Of course, in the future, all the graffiti from the suburbs need a more detailed visual study both as the fragments of ceramics and their exact professional sketches, and comparative analysis of this type of inscriptions from many ancient Greek sites.

This article publishes the terracotta thymiateria (incense burners) from Olbia Pontica which represent busts of Aphrodite with Erotes on her shoulders. They were used probably in activities related to Aphrodite's cult for diffusing incense and as votives. They derive from excavations at houses, a stoa and the bothroi (sacrificial pits) at the central and western temene; they date to the period between the late third and the first half of the second centuries bc. The publication of such items coincides with ongoing research into the southern sacral precinct in Olbia dedicated to Aphrodite. This article explores the significance of the iconography of these objects and their use in cult activity related to the cult of Aphrodite at Olbia.

Abstract:

Persistent organochlorine pollutants (POPs) like polychlorinated biphenyls (PCBs) and DDT residues (DDTs) can still be a problem for the aquatic environment and the human health. PCBs and DDTs were determined in three freshwater fish species: common carp (Cyprinus carpio), catfish (Silurus glanis), pike-perch (Sander lucioperca) and two marine fish: shad (Alosa pontica pontica) and grey mullet (Mugil cephalus). The freshwater fish samples were collected from the Danube River and from Black Sea, Bulgaria in 2010. The POPs were analyzed in order to investigate the presence of PCBs and DDTs in fish species from Danube River and compared the results to the levels in marine fish species from Black Sea. The fifteen congeners of PCBs, p,p’-DDT and its two main metabolites p,p’-DDE and p,p’-DDD were determined by capillary gas chromatography system with mass spectrometry detection. DDTs were the predominant contaminants in investigated species, with the p,p’- DDE contributing to more than 67% to the total DDTs. In freshwater fish concentrations of DDTs were found from 19.2 to 30.3 ng/g ww and PCBs concentrations - from 6.2 to 12.6 ng/g ww. The highest levels of PCBs and DDTs were determined in shad. The levels of DDTs and PCBs were determined lower than those found in similar fish species from other aquatic ecosystems.

Abstract:

The blue aleurone trait has been suggested as a useful genetic marker in wheat (Triticum aestivum L.). However, little information is available on its transmission in diverse backgrounds and on its use to identify hybrid seed. UC66049, a hexaploid spring wheat with a spontaneous translocation that included the gene for the blue aleurone trait (Ba) from Agropyron elongatum (Host) P.B. (synonymous with Elytrigia pontica (Podp.) Holub), was crossed to seven wheat cultivars to test the transmission of the trait. UC66049 was crossed to male-sterile red wheat lines to evaluate the blue aleurone trait as a marker for confirming hybridity. Ba segregated as a dominant gene that was transmitted normally through the male and female gametes. For 6 of 7 crosses with diverse pedigrees, we experienced problems with misclassification of the aleurone color in the F2 seed generation, determined by the F3 seed family data. The blue aleurone trait is a good genetic marker; however, progeny testing may be needed to confirm the F2 genotypes in some environments or genetic backgrounds. Moreover, Ba is useful in determining the amount of controlled hybridity as opposed to self-fertility and (or) outcrossing in genetic male-sterile wheat lines. The use of Ba to confirm doubled haploidy was proposed.Key words: Agropyron elongatum, seed color, genetics, Triticum aestivum, Elytrigia pontica.

Full text

Abstract:

AbstractCaesar’s speech Pro Bithynis is usually considered to be an expression of the positive relationships between Caesar and the Kingdom of Bithynia. The context in which the speech was delivered is, however, unclear.By means of a lexical analysis of the two extant fragments of the Pro Bithynis, this paper aims at providing a new interpretation of the speech and its historical background. Caesar probably delivered the speech not immediately after King Nicomedes’s death – as commonly accepted – but after the Roman siege of Heraclea Pontica, when the proconsul M. Aurelius Cotta, Caesar’s propinquus, was accused of having sacked the city.As had already happened in Macedonia (thanks to Dolabella’s prosecution) and in Greece (Caesar represented some Greeks in a process against C. Antonius around 79 BC), the Bithynian affair represented a further occasion for Caesar to win over friends and allies among foreign communities.

Установлены уровни изменчивости морфологических признаков ассимиляционного аппарата и плодов С. avellana L., сортов С. pontica C. Koch., которые согласуются с зимо и засухоустойчивостью. Кластерный анализ позволил выявить корреляцию признаков при 5 уровне значимости. Для целей защитного лесоразведения и озеленения засушливых районов рекомендованы Corylus avellana и Черкесский2 с выраженной вариабельностью морфологических признаков, которая указывает на их широкую экологическую валентность и адаптационные возможности в рассматриваемых условиях. The urgency of studying the ecological plasticity of woody plants in connection with the need to select an adapted species composition of trees and shrubs for protective forest plantations in the context of climate change is shown. It is established that the ecological plasticity and tolerance range of plants is associated with the ability of organisms to adapt to a particular range of environmental factors. The article presents the taxonomic composition of nut crops in the collections of FSC Agroecology RAS. Six species of Juglans: J. regia, J. mandshurica, J. cinerea, J. rupestris, J. ailanthifolia, J. nigra and three species of the genus Corylus: С. avellana L., С. аmericana W., varieties of C. pontica C. Koch the President, Futkurami, Circassian2. Data on positive experience of cultivation of Corylus avellana L. in plantation plantings (1,6 hectares, landing ordinary, the scheme of placement of 55 m) in the conditions of southern chernozems are given. The purpose of the research is to study the ecological plasticity of nutbearing shrubs of the collections of the Federal scientific center for Agroecology Russian Academy of Sciences. For example, a generic complex Corylus submissions received on the environmental plasticity of nut bushes in the conditions of brown (the cadaster nubmer 34:36:0000:14:0178), light chestnut soils (34:34:000000:122 34:34:060061:10). The levels of variability of morphological features of the assimilation apparatus and fruits of Corylus avellana L., С. pontica C. Koch varieties were established., which are consistent with winter and drought resistance. Cluster analysis revealed the correlation of features at 5 significance level. Corylus avellana and Circassian2 with a pronounced variability of morphological features, which indicates their broad ecological valence and adaptation capabilities in the conditions under consideration, are recommended for the purposes of protective afforestation and greening of dry areas.
