We studied self-overgrowing logging areas of different age and degree of degradation in the middle mountains of the Northwestern Caucasus on rendzik. A change in the flora of the control beech-fir forest to high grass meadow and herbaceous-shrub vegetation was established. Vegetation diversity, tiering, herbage height, and projective cover of the herbaceous layer depend on the age of felling and the degree of disturbance of the soil and vegetation cover during logging. Minimal diversity and projective cover was revealed for the logging of 2 years age. Diversity of flora at the sites of medium and severe disturbance of 10-year old logging decreases by 20% relative to the control site. On the peripheral area of weak disturbance grass-bush vegetation with increased flora diversity by 17 % is formed.

Abstract In the Russian crop production winter and spring wheat occupy a leading position in the structure of grain crop areas. More than 70% of grain crops are heavily and moderately clogged, so the need for weed control is obvious. The study of the floral diversity of segetal vegetation is a prerequisite for assessing the state of agrocenoses and measures to protect them Satya is devoted to an urgent problem-the description of the floral composition of the segetal vegetation of the agrocenoses of winter wheat and spring barley of the Northern Azov region. The article analyzes the floristic diversity of the segetal vegetation of the agrocenoses of winter wheat (Triticum aestivum) and spring barley (Hordeum vulgare) of the Northern Azov region. Taxonomic and biomorphological analyses are given. Classification of life forms of segetal vegetation according to I.G.Serebryakov and K. Raunkier was carried out. The research was carried out on winter wheat and spring barley crops within the Myasnikovsky, Neklinovsky and Aksai districts of the Rostov region. In total, 1106 geobotanical descriptions were performed (1082 descriptions on winter wheat agrocenoses and 24 descriptions on spring barley agrocenoses). It was revealed that despite the significant difference between the number of weed species in the agrocenoses of winter wheat and spring barley, the typological composition of the weed component is largely similar. The ratio of life forms revealed the predominance of spring annuals according to I.G. Serebryakov (38.5% for winter wheat agrocenoses and 45% for spring barley agrocenoses) and K. Raunkier terophytes in both crops (42.3% for winter wheat agrocenoses and 50% for spring barley agrocenoses).

The estuaries of the Kuban’s delta are a unique and highly productive ecosystem. This complex of reservoirs played a significant role in the formation of fish productivity of such valuable commercial species as pike-perch (Sander lucioperca) and taran’ (Rutilus heckelii). Despite a number of negative changes in the bioecological conditions in the modern period, they still retain a fairly large productive area of natural spawning grounds. In the bayous of estuaries and in the estuaries themselves, studies of juvenile pike-perch and taran’ were carried out. No juveniles of the studied fish were found in the catches of the Soloviev duct. Pike-perch was found only on the Peresypsky and Kulikovsky ducts in single copies. Taran’s juveniles were present in the catches at each station. The minimum values of length and mass were observed in juvenile rams caught in the Peresypsky duct, the maximum values were noted in the Kulikovo duct. A noticeable difference in values can be explained by the extended spawning and, accordingly, by the different-time hatching of larvae. The juveniles of the pike-perch and taran’, coming out to sea from the Azov estuaries of the Krasnodar Territory in 2021, had good length and mass indicators, indicating favorable conditions for its development. The survival rate of such juveniles in the sea is higher. The intensity of its descent during the observation period was low, which may indicate not entirely favorable conditions for the survival of juveniles in the coastal part of the sea. Since the increasing salinity of the Sea of Azov has a negative impact on the condition and slope of juvenile pike-perch and taran’. The supply of fresh water in the right time and in sufficient quantity can improve the situation, but in the current climatic situation this is unlikely.

In previous studies, we demonstrated for the first time the biodegradation of white phosphorus by the molds Aspergillus Niger. However, studying the mechanisms of resistance of the fungus to such a toxic substance is essential. There may be several such mechanisms, of which two are most likely. The cell wall of the fungus is a barrier to the penetration of white phosphorus into the cell. In such a case, an increase in cell wall thickness should be observed in response to exposure to the toxicant. The second mechanism is associated with the expression of stress genes and the production of proteins by the fungus involved in the neutralization of toxicants, including white phosphorus. The microscopic and proteomic studies carried out in the present work have shown that both resistance mechanisms take place. In addition, white phosphorus causes a general activation of metabolism, accompanied by an increase in the number of mitochondria in the cells. It was shown that white phosphorus has little effect on the ratio of living and dead cells in the colonies of fungi, i.e. resistance to it is very high.

The paper attempted to use a hyperspectral camera under controlled conditions of a laboratory experiment to obtain unique curves of seasonal dynamics of NDVI values, allowing to identify the maple species. The objects of study were samples of Acer campestre L., Acer negundo L. and Acer saccharinum L. The maple leaf was surveyed in the laboratory using a Cubert UHD-185 hyperspectral camera under artificial light. To monitor the results, the content of chlorophyll was determined by a spectrophotometric method. Studies were conducted during the growing season of maples from the phenological phase of "full leaf unfolding" to the phenological phase of "the beginning of autumn leaf coloring. It is established that the seasonal dynamics of the NDVI value is similar to the dynamics of chlorophyll a, calculated by the spectrometric method. Empirical NDVI regression lines in all three maple species are synchronous at most survey times, especially in the maximum and minimum zones. However, the difference between NDVI maple species is not as drastic as in chlorophyll a, although in most survey periods the NDVI value of A. campestre is higher than that of the other two species of maples. We assume that the NDVI signature cannot be used to separate species of the genus Acer. However, to identify genera that vary significantly in phenology, the use of NDVI signature is quite possible.

The features of the metabolic processes of transformation of the organic and mineral components of the soil are determined mainly by the complex of soil enzymes, the abundance and qualitative composition of the microbiocenosis. The activity of soil enzymes is an additional diagnostic indicator of soil fertility and its changes under anthropogenic impact. Studies of the activity of soil enzymes in various zones of the city of Sumgait - a large industrial center in which the petrochemical and oil refining industries are concentrated. The results of field studies showed that the activity of soil enzymes was not the same in different zones of the city of Sumgait. Significant differences in the catalase activity of soils of roadside and industrial zones and soils under parks have been established. With technogenic pollution, the functional activity of soil microorganisms is significantly reduced. In comparative terms, the activity of all soil enzymes is most suppressed in industrial zones, and to the least extent in park zones. The analysis shows that the technologically polluted soils of the industrial city of Sumgayit are characterized by weak stability of soil enzymes. These indicators reflect the specificity of pollutants, the degree of contamination, the nature and intensity of biological processes in soil affected by industrial impacts - industrial and transport emissions. The research results can be part of the database for an objective assessment of the soil cover of urban landscapes in Sumgait, to prevent the deterioration of their environmental functions, for the development of the scientific basis for the use of microorganisms in technologies for cleaning and increasing the fertility of urban soils.  

The aim of this work is to investigate features of physical properties of ordinary calcareous chernozems of the Rostov region. Amendments to methods for studying the soil bulk density and porosity of the investigated soils are proposed. To determine the hydrological constants, such as the capillary moisture capacity  and the full water capacity of ordinary calcareous chernozem, are proposed using the calculate-analytical method developed by I.V. Morozov. The principle of the method is based on the relationship between hydrological constants and the physical and mechanical properties of the soil.  

On the biological degradation of white phosphorus On the biological degradation of white phosphorus   1 Institute of Organic and Physical Chemistry named after A.E. Arbuzov. Kazan Scientific Center of the Russian Academy of Sciences. Arbuzov St., 8. Kazan, 420088. Republic of Tatarstan. Russia. E-mail: mindubaev-az@yandex.ru 2 Kazan (Volga Region) Federal University. University St., 18. Kazan, 420008. Republic of Tatarstan. Russia. Abstract For the first time different taxonomic groups of microorganisms (fungi, Streptomyces and bacteria) are inoculated on culture medium containing white phosphorus as the single source of phosphorus. On these media microorganisms grew and have not experienced phosphorus starvation. It is the world's first example of the inclusion of white phosphorus in the biosphere cycle of elemental phosphorus. The highest concentration corresponds to 5000 times excess of MPC of white phosphorus in wastewater. The comparison of the sequences of ribosomal genes of the fungus, steadily metabolizing the white phosphorus, with sequences of the GenBank database, allowed us to identify this microorganism as a new strain of Aspergillus niger, to which we have assigned the number A. niger AM1. Inoculation of A. niger AM1 in medium containing just two sources of phosphorus (phosphate and white phosphorus) demonstrated that P4 does not exhibit toxic properties in relation to this microorganism. In the presence of white phosphorus it grows at the same rate as in the absence thereof. This is the only example of the lack of white phosphorus toxicity to a living organism. Our previous studies have demonstrated the absence of white phosphorus toxicity for Aspergillus niger AM1. However, the toxic properties of the substances are of different nature. It is of great interest to study the genotoxicity – a possible source of mutations. In the present work SOS-lux test has demonstrated genotoxicity of white phosphorus. This result is obtained for the first time – all the available literature sources reported no genotoxic properties of white phosphorus. Allium test showed the mitotoxic effect of white phosphorus on eukaryotic cells. A very interesting and unexpected result was the discovery of a mutant Aspergillus niger AM1. In comparison with an ancestral strain this mutant possesses an unusual morphology and grows more intensively in culture medium with white phosphorus. Three strains of A. niger, sent from the All-Russian collection of microorganisms, also showed much higher resistance to white phosphorus than bacteria. According to preliminary data, resistance to white phosphorus the A. niger is fixed in the genome.

Resource-saving elements of soybean cultivation technology on the slopes of the Rostov region Resource-saving elements of soybean cultivation technology on the slopes of the Rostov region Rychkova M.I., Gaeva E.A., Mishchenko A.V. Federal Rostov Agricultural Research Center, Rassvet. Е-mail: emmaksay@inbox.ru. Abstract. The article presents the actual results of research on the development of resource-saving elements of soybean cultivation technology, providing moisture saving, high productivity and soil protection from erosion. Two-year studies were carried out on the erosion-dangerous slope of the South-Eastern exposure of the Bolshoy Log beam, Aksai district of the Rostov region in the system of contour-landscape organization of the territory in 2017-2018. Studied two methods of primary tillage – otvalnuyu adopted for monitoring and chisel. Chisel tillage in the cultivation of soybean was performed by chisel plow. Dump processing was carried out with a plow blade. The mineral nutrition system included three backgrounds: natural fertility recommended by zonal systems and increased by half. It is established that to prevent possible erosion it is recommended to cultivate soybeans in the system of contour-band placement of fields. It is shown that the payback of the crop fertilizers on the version with the chisel treatment of the soil is higher than on the dump. Increasing the dose of fertilizer in half reduces the payback of fertilizers by 18.9-19.4 %. It is revealed that the approved soil protection (chisel) tillage can significantly reduce the erosion processes – soil flushing by 22.9%, runoff – 10.0%, the cost of fuel and lubricants-18.8%, increase the accumulation of reserves of productive moisture in the soil with a more economical expenditure, yield – by 30.2 – 32.1%, conditional net income-up to 6.6 thousand rubles /ha, profitability-by 42.1%, recoupment of direct costs yield of 1.4 rubles per ruble in comparison with the same indicators at the dump plowing.

Location on the Caucasus Potentilla multi-advisable (Potentilla multifida L.) Location on the Caucasus Potentilla multi-advisable (Potentilla multifida L.)  O.N. Demina, L.L. Rogal'  Abstract: The paper describes the Gum-Bashi Pass, which is named after the homonymous right-bank tributary of the Kuban - the Mara River. The distribution of grass vegetation on the Gum-Bashi Pass, as on the whole Rocky Caucasus Mountains, is associated with vertical zonality or altitudinal belt ecosystems. The characteristic of indigenous subalpine vegetation is given: on gentle northern slopes and plateaus of the Rocky ridge formed lush grassy meadows; Petrophytic steppes develop on the steep slopes of the southern, southeastern, and southwestern exposures. The most common types of natural forage lands on the Gum-Bashi Pass are mountain meadow communities on mountain sod-podzolic, gray and brown forest soils, and meadow-steppe communities on leached and podzolized black soil. However, the main purpose of the work is to describe a new plant species, Potentilla multifida L., which we discovered for the first time in the territory of Karachay-Cherkessia, in the Rocky Ridge system on the Gum-Bashi Pass and confirming its growth in the Caucasus. In describing this species, it is mentioned that this herbaceous perennial reaches 40 cm in height. The leaves of the plant are green above and beloiclochic below, dissected into linear lobes. The flowers are small, on thin pedicels, pale yellow. The beginning of its flowering was recorded when the species was collected. A critical summary of references to this species and an indication of the need to describe a new Caucasian form is given. In conclusion, one more time focuses on the need for this description, studying the distribution of P. multifida in the Caucasus and its phytocenotic environment. The article is illustrated with a large number of photos.

Effect of different phytohormones on Austrian sage multiplication (Salvia austriaca Jacq.) Effect of different phytohormones on Austrian sage multiplication (Salvia austriaca Jacq.) Vasilchenko Elena V., Sereda Mikhail M., Varduni Tatiana V. Southern Federal University, Rostov-on-Don, Russia  Abstract: The influence of phytohormones such as 6-benzylaminopurine, naphthylacetic acid and indole-3-acetic acid on the Austrian sage multiplication (Salvia austriaca Jacq.) in an in vitro culture is discussed in the paper. Austrian sage is the medicinal, essential oil, melliferous and ornamental steppe herb, included in the Red List of the Rostov region. The study was conducted in the laboratory of cellular and genomic technologies of plants of the Botanical Garden. Seeds from the collection of the Botanical Garden of the Southern Federal University were used as the primary explant. For cultivation the Murashige and Skoog medium was used. Murashige and Skoog medium without the addition of phytohormones was used as a control. Evaluation of the multiplication efficiency was carried out after 21 days. The multiplication factor was calculated as the number of new shoots. The highest multiplication factor was observed in the medium with the addition of 0.5 mg / l of 6-benzylaminopurine and 0.1 mg / l of naphthylacetic acid. This concentration of phytohormones is recommended for micropropagation of Austrian sage. The concentration of auxins (IAA and NAA) 0.3 mg/l leads to a decrease in the efficiency of Austrian sage multiplication. The height of shoot was approximately the same and no statistically significant differences were found on all tested mediums. It should be pointed out that with a greater concentration of phytohormones physiological abnormalities was observed.

Methods of soil fertility preservation on eroded slopes of Rostov region Methods of soil fertility preservation on eroded slopes of Rostov region Gaevaia Е.А. Federal Rostov Agricultural Research Center, Rassvet. Е-mail: emmaksay@inbox.ru. Abstrac: Тhe Studies were carried out in a multifactorial stationary experiment in 1991-2018 years. the Experiment is located on the slope of the beam of the Big Log of Aksai district of Rostov region. The soil of the experimental site is ordinary heavy loamy Chernozem on loess-like loam, medium-eroded. In the experiment studied two crop rotation zernopererabotki (I) and sertralineprograms (II), and three levels of organic-mineral system of fertilizers («0» – natural fertility; «1» – cattle manure 5 t + N46P24K30 and «2» – cattle manure 8 t + N84P30K48 1 hectare). The aim of the study was to study the balance of humus depending on the design of crop rotations located on the eroded slopes of the Rostov region, to identify ways to preserve soil fertility at the initial level and increase it. As a result of the research, the amount of washed soil was determined. The importance of plant residues in the accumulation of humus is shown. It is established that the intensive use of agricultural land in the Rostov region without fertilizer leads to a reduction in the humus content in the soil. The role of perennial grasses in reducing soil flushing by 35.6% was studied. It is shown that the long-term use of organic fertilizers in crop rotations at a dose of 5 tons of cattle manure and N46P24K30, as well as the introduction of 20% of perennial in the crop rotation allows to maintain a positive balance of humus at the level of (+35 kg/ha) in the grain-grass crop rotation. Increasing the dose of fertilizer to 8 tons of cattle manure and N84P30K48 contributes to the accumulation of humus up to (+100 kg/ha) in the grain crop rotation. The possibility of replacing organic fertilizers with 1-2 t/ha of wheat straw using compensatory doses of nitrogen fertilizers is shown.

Features of the geographical structure of the Krivoy Rog urban flora (Ukraine) Abstract: To identify the specificity of the formation of any flora and its relationship with other floras is possible using the geographic analysis. The aim of the work was to analyze the geographical structure of the spontaneous flora of Krivoy Rog city and to reveal the characteristics of its forming under the influence of urbanization. The object of research was all the species of higher plants, which spontaneously settled in the administrative borders of the city and its green zone. The geographical structure of the flora was understood as the inherent spectrum of geographic elements (arealogical groups). The analysis of the ranges of the species of the native fraction of Krivoy Rog urban flora was carried out on a zonal-regional basis, while the group of alien species was analyzed using the primary ranges of the species. Тhe geographic analysis reveals the autochthonous and allochthonous nature of the Krivoy Rog urban flora, its geographic connections at the level of high-ranking chorions: Holarctic, Palaearctic, Eurasian, Mediterranean.  In general, all the species belong to 7 basic and 2 transitional types and 25 geographic elements; alien species form the separate group. Identity and individuality of the city flora are determined by the species of the Black Sea type of the ranges, there are 147 ones (13,5%). A significant percentage of the alien species (30,66%) refers to the peculiarities of the modern florogenesis in urbanized territories; among these species an important role belong to representatives of the North American type of migratory elements (over 20% of the total number of alien species).  

Seventy years' experience of creation of the state protective forest strips in a steppe zone of Russia In a steppe zone of the European territory of Russia artificially created 8 state protective forest strips (SPFS) are located. Research objective: on the basis of analytical materials to carry out the assessment of a condition of SPFS of a steppe zone of the European part of Russia, to reveal their recreational potential. Materials and methods of a research: general information, creation history, ways and technologies of creation of SPFS, lesovodstvenny actions in them were studied and analyzed according to references and share materials. Information on existence and condition of SPFS in regions of a steppe zone of the European part of Russia was established according to the state forest register. For certain regions the recreational appeal of SPFS paid off.  In article the history of creation of these strips, since adoption of "The Stalin plan of transformation of the nature" from 20 оctober 1948 g is considered.  On this project in 15 years (1949-1965) it was planned to create 117.9 thousand hectares of SPFS, but actually works were finished in 1972. 4 water separate and 4 prirechnykh state protective forest strips were created.  Now the total area of SPFS in a steppe zone of the Russian Federation is 85.7 thousand hectares. At the same time more than 13% of their area are presented by not forest lands, and covered with forest vegetation are about 80%.  From tree species as a part of SPFS the Quércus róbur prevails, the second place is taken by an Fráxinus excélsior  and F. lanceolate, the third Ulmus pumila. It is established that more than a half of the spaces are occupied by middle-aged plantings, 16.6% – coming, 8.9% – ripe and perestoyny. The state protective forest strips have the recreational potential which increases in process of increase in a share of SPFS as a part of forest fund of the territory; and in process of decrease in the general woodiness of the territory.  The SPFS recreational value increases at increase in their availability (first of all transport) in comparison with other territory of forest fund.

Molecular-genetic and physiological features of chlorophyll-deficient sunflower mutants with extra-nuclear inheritance type Makarenko Maksim Stanislavovich, Kovalevich Aleksey Aleksandrovich, Shamova Tat'yana Vladimirovna, Kazancev Mikhail Yur'evich, Usatov Aleksandr Vyacheslavovich Southern Federal University, Rostov-on-Don, Russia Abstract: Chlorophyll-deficient mutants are the appropriative models for providing investigations both of photosynthetic apparatus and nuclear-cytoplasmic relationships. In the current research, the genetic and physiological analysis of sunflower (Helianthus annuus L.) mutant lines (en:chlorina-1, en:chlorina-6, en:chlorina-7) was conducted. All the analyzed mutant lines have a yellow-green phenotype with an extra-nuclear type of mutation inheritance and have been obtained on the genetic basis of single inbred line 3629 by N-nitrosomethylurea induced mutagenesis. Matching the data of photochemical activity with chloroplast DNA genotyping data revealed that en:chlorina-1 mutant phenotype is associated with a non-synonymous mutation in the psaB (Thr586Ile) gene, en:chlorina-6 – in the psaB (Gly385Glu), and en: chlorina -7 – in psaA (Thr528Ile) and psbB (His157Tyr) genes.

Ecological-modifying effect of soil contamination with heavy metals on the contact interaction of human leukocytes Evstropov Vladimir M. Don state technical University, Rostov-on-Don, Russia Abstract: It is known that by assessing the intensity of the contact interaction of lymphocytes with granulocytes, we can detect the processes of preclinical carcinogenesis. Heavy metals have carcinogenic properties, and the interaction of lymphocytes with granulocytes, which characterizes the level of transforming cells, is reduced in people permanently residing in the city, compared to people in rural areas [6], apparently under the influence of increased of anthropogenic environmental pollutions. At the same time, the contact interaction of lymphocytes with granulocytes can be considered as a cytological phenomenon, which characterizes the functional state of leukocytes, in particular their locomotor and adhesive potencies. Based on the characteristics of various functional zones of the city of Rostov-on-Don, established on the basis of the determination of the total indicator of soil contamination with heavy metals (zinc, arsenic, copper, lead and nickel), we carried out a comparative analysis of the activity of contact interaction of leukocytes of various types (lymphocytes and granulocytes) among the residents of two functional zones of the city, who differ in the degree of soil contamination with heavy metals: with moderately dangerous and acceptable levels of contamination. The results of the study showed that the residents of the functional zone of the city with a moderately dangerous level of soil contamination with heavy metals, the intensity of the interaction of the studied leukocytes was lower than that of those living in the territory with an acceptable level of pollution. We assume that the revealed decrease in the intensity of contact interaction of leukocytes in people long-term living in areas whose soil is moderately polluted with heavy metals is caused by chromosomal abnormalities and transformation of leukocytes, in particular lymphocytes.
