Extraction of Rare Earth Elements from Brown Coals of the Sergeevskoe Deposit (Amur Region) According to Experimental Data

A series of experiments on the leaching of rare earth elements (REEs) from Miocene brown coals of the Sergeevskoe deposit with water and alkaline and acid solutions was carried out. Using a set of methods (ICP MS, XRD analysis, heavy concentrate analysis, SEM EDS, and IR spectrometry), it was revealed that acid leaching was the most effective: 72–99% of REEs was extracted with a 1 M solution of hydrochloric acid in 24–48 h. This fact indicates that most of the REEs in the brown coals of the Sergeevskoe deposit were associatedwith the organic matrix in the form of complexes with the carboxyl groups of humic and fulvic acids. The high percentage of REE extraction indicates the possibility of using coals from the Sergeevskoe deposit as an easily enriched source of REEs.

New Data on Agaricoid Basidiomycetes of the Shantar Islands National Park (Khabarovsk Territory, Russia)

The Shantar Islands is an archipelago in the western part of the Sea of Okhotsk, at a distance of about 50 km from the mainland coast. In August 2019, we have carried out mycological studies on the islands of Bolshoi Shantar and Prokofiev. An annotated list is given of 103 species first found in the national park; 21 species of them were found in Khabarovsk Territory for the first time. The Shantar Islands are geographically the northernmost area in the Khabarovsk Territory, where specialized mycological studies were carried out. Such new species for the region as Cortinarius acutus, C. bivelus, C. traganus, Chromosera lilacina, Laccaria bicolor, in the Russian Far East were previously known only from more northern regions: Magadan Region, Kamchatka, Chukotka, Yakutia and from the taiga zone of Amur Region. Taking into account previously published data, a total of 105 species of agaricoid basidiomycetes are known for the national park.

Reemergence of arctic-like rabies virus in a rabies-free area in the Amur river basin

Background: A descriptive epidemiological study of the rabies outbreak in the Amur Region of Russia (ARR), which remained rabies-free from 1972 to 2017, was carried out. During 2018-2022, 49 animal rabies cases and one human rabies death were documented in the ARR. This study aimed to detect possible ways of incursion and features of the spatial spread of rabies virus (RABV) in ARR, which was considered rabies-free for 45 years. Methods: After the beginning of the outbreak, 1,450 animal brain samples were tested using a direct fluorescent antibody test. Genetic analysis of RABV isolates was carried out (n = 9). GIS was used to analyze the spatial spread of rabies in ARR and adjacent territories. Results: Rabies has been confirmed in red foxes (Vulpes vulpes ) - 38.8%, raccoon dogs (Nyctereutes procyonoides ) - 10.2%, wolves (Canis lupus ) - 14.3%, dogs - 18.4% and farm animals - 18.3% (n = 49). The first cases were detected south of the ARR, 30 km from the state border between Russia and China. In 2018-2022, the RABV spread within the forest-steppe landscapes of the Zeya-Bureya Plain northwesterly; the maximum distance from the first recorded event was 192.4 km (Me = 77.6). According to a phylogenetic analysis, the isolates from ARR belonged to the Acrtic-like-2 RABV lineage and showed the maximum similarity to the isolates recovered in the province of Heilongjiang (China, 2011, 2018) and the Jewish Autonomous Region (Russia, 1980). Conclusion: Rabies was most likely introduced by wild carnivores from the adjacent territories of Russia or China, located downstream of the Amur River.

Prospects for the Creation of a Russian-Chinese Cross-Border Zone of Economic Cooperation Between Blagoveshchensk and Heihe

The article analyzes the history and prospects for the implementation of the project of a cross-border zone of economic cooperation between Russia and China. As the most promising site for the placement of such a zone, a "pre-bridge territory" is considered, adjacent to the Kanikurgan-Heihe bridge crossing in the immediate vicinity of the cities of Blagoveshchensk (Amur Region) and Heihe (Heilongjiang Province). At the same time, the author concludes that at present the Russian leadership is aimed at creating not a cross-border, but a border zone, which, nevertheless, should cooperate closely with the border zone of economic cooperation located on Chinese territory in Heihe. Bearing in mind that the subject matter under consideration is in many ways the subject of terminological and factual confusion, the author pays particular attention to the definition of what is meant by the cross-border and border zone of economic cooperation, which implies some preferential regime, etc.

Влияние энергозатрат на формирование рационального машинно-тракторного парка

In the modern period, the structure of enterprises engaged in the production of agricultural products differs significantly from each other. The main differences include the presence, contour and condition of sown areas, as well as the composition and quality condition of the machine and tractor fleet. This can be explained by the fact that, along with enterprises that have large acreage and an energy-saturated machine and tractor fleet, small peasant farms (KFH) also participate in the production of agricultural products and the formation of the gross regional product in terms of the size of the acreage and the composition of the machine and tractor fleet. At the same time, they make a significant contribution to the production of gross domestic product. Thus, in the Amur region, the share of agricultural enterprises from all agricultural products produced in the region in the total volume accounts for up to 25 ... 28 percent. Thus, in the current production conditions, the issue of rational selection and formation of a machine and tractor fleet that would be optimal for both large agricultural holdings and small farms becomes particularly relevant. At the same time, when forming a machine and tractor fleet, the most responsible is the financial component, since the cost part, of course, is not comparable between large agricultural enterprises with high production volumes and small farms. If we analyze the market of agricultural machinery offered by manufacturers, it is very diverse both in price value and technological efficiency, and in energy saturation. Therefore, for the rational selection of the composition of the machine-tractor fleet and the train of machines, it is necessary to apply various methods based on the financial capabilities of a particular agricultural enterprise and other components of the production process. In this paper, we propose a method for selecting and forming a machine and tractor fleet, which is based on the use of energy consumption through the profitability coefficient, as an indicator that is most independent of market conditions.

Применение комбинации физических полей для повышения посевных качеств семян сои

One of the main conditions for obtaining a high soybean yield is maintaining optimal sowing and harvesting times, as well as pre-sowing seed treatment aimed at increasing the sowing qualities of the seed material. In the Amur region, the optimal sowing time is considered to be the period when the average daily air temperature reaches 10–14º degrees Celsius. In this connection, as studies have shown, mid-ripening and late-ripening soybean varieties are sown at the end of May, usually on the 20th-25th, and early-ripening varieties are sown a week later. Maintaining these sowing dates contributes to better development of soybean plants, which allows the necessary work to care for the crops to be carried out in favorable conditions. The studies carried out show that all sowing work in the region must be carried out in the shortest possible time and no later than June 5. In addition to the conditions listed above, to increase soybean yields, it is necessary to pay due attention to other indicators, such as the quality of sowing work, selection of sowing method, compliance with seeding standards, sowing density and depth of seed placement in the soil, etc. Also, one of the promising ways to improve the sowing qualities of soybean seeds is to improve the mechanization used during pre-sowing treatment. The presented article presents the results of research on improving the pre-sowing qualities of seed material through the use of thermal and electromagnetic physical fields in combined processing of soybean seeds.

DETERMINATION OF FREE AMINO ACIDS IN UNDERGROUND ORGANS OF ELEUTHEROCOCCUS SENTICOSUS RUPR. ET MAXIM

A study of free amino acids in the underground organs of Eleutherococcus senticosus (Eleutherococcus senticosus Rupr. et Maxim, family Araliaceae) was carried out. The material for the study was samples of rhizomes and roots of Eleutherococcus collected in the Amur Region, Jewish Autonomous Region, Primorsky and Khabarovsk Territories.
 Amino acids were determined by GC-MS. According to the results of studies, from two to nine amino acids were found in the rhizomes and roots of Eleutherococcus senticosus, of which 6 are nonessential (alanine, proline, serine, glutamine, pyroglutamic acid, aspartic acid) and 3 are essential (valine, leucine, threonine). The total content of amino acids in the studied samples averaged 20.1 mg/100 g. It was revealed that the dominant group is heterocyclic amino acids, the representatives of which include proline and pyroglutamic acid. The average content of proline and pyroglutamic acid was 4.9 and 7.1 mg/100 g, respectively. Based on a comparative analysis of the amino acid composition of ten samples, it was shown that the amino acid composition of the rhizomes and roots of Eleutherococcus from different populations varies. As a result of a cluster analysis based on the content of amino acids in the studied samples, two groups are distinguished: samples from the Khabarovsk Territory - Amur Region, samples from the Primorsky Territory - Jewish Autonomous Region (Leninsky District).

Геногеография фармакогенетически значимых ДНК-маркеров CYP2C19 суперсемейства цитохромов в народонаселении России и сопредельных стран

Genetic testing of each patient aimed at detecting the pharmacogenetic marker carrier state is challenging for healthcare system. However, knowledge about the frequencies of pharmacogenetically important genes enables making decisions about treatment based on the patient’s ethnicity. The CYP2C19 cytochrome gene involved in biotransformation of a broad spectrum of drugs is one of the most important. The study was aimed to determine the frequencies of major CYP2C19 variants and the patterns of their spatial variability in the population of Russia. The database Pharmacogenetics of the Population of Russia and Neighboring Countries created by the research team was used to determine frequencies of the CYP2C19 *1, *2, *3, *17 variants and their genotypes: *1 – 53 populations, n = 2261 samples; *2 — 79 populations, n = 6346; *3 — 92 populations, n = 7517; *17 — 35 populations, n = 3313. We have created a cartographic atlas that includes the *1, *2, *3, *17 frequency maps, correlation maps, and genotype frequency maps. Specific data on the frequencies of CYP2C19 variants and their pharmacogenetically significant genotypes in the major ethnic groups of Russia are provided. The cartographic atlas enables prediction of frequencies of significant CYP2C19 variants and their genotypes in the peoples, information about which is currently missing. The *1 and *2 variants gene geography is characterized by similar pattern: the combination of longitudinal trend of frequency increase from west to southeast and latitudinal variability of frequency increase from north to south in the Asian part of the region. Variant *3 is characterized by the clear longitudinal vector of frequency increase from 0 in the west to the world’s maximum in the Amur region. Variant *17 shows a pronounced longitudinal trend with the oppositely directed vector of frequency decrease from west to southeast. The correlation maps indicate regions, where the similarity between core patterns is disrupted.

About micro- and nanoscale gold in the veil of gold-bearing territories (on the example of a mineralization site in the basin of the river Adamikha, Amur region)

The article identifies the problem of the need to take into account micro- (1 mm to 0.12 microns) and nanoscale (<0.12 microns) gold in placers and weathering crusts in order to increase the objectivity of their and eroded ore objects potential assesment. The results of technological studies of gold-bearing deluvial deposits in the valley of the Adamikha river basin (Amur region) are presented. A quantitative assessment of the content of micro- and nanogold by fractions of loose material was made. It was found that in the studied sample of such material (weighing 50 kg), the major part (78%) refers to native gold with a dimension of <0.12 microns. Including 0.1% is in concentrator minerals, and 3.5% of the fraction (<3 microns), probably colloidal, is in technical solutions of wet sieve. Moreover, 3/4 of the total amount (18% visible and 57% invisible) of gold is concentrated in the fraction (1–0.5 mm). It is established that, taking into account the free invisible gold, the resources of the precious metal of the object under study increase by 3.4 times. The possibility of a more objective quantitative assessment of the Au potential of promising areas, taking into account the content of fine gold, is shown. Possible ways of solving the problem of a more reliable assessment of geological reserves and estimation of forecast gold resources, taking into account the knowledge of the quantities of micro- and nanoscale fractions, are proposed. The authors believe that studies of the forms of allocation and distribution, including invisible (<0.12 microns) gold in placers and weathering crusts will contribute to a more correct assessment of the studied gold-bearing objects and territories with the possibility of increasing the real resource potential of the precious metal in the region.

Socio-Demographic Aspects of Floods in the Russian Far East in 2013–2023

The article presents the results of a study of floods in the southern regions of the Russian Far East. The analysis is based on the search for options for flood prevention, as well as better management of the consequences of floods to improve the quality of life of the population. The data on damage from floods in the period from 2013 to 2023 in certain Far Eastern regions are analyzed. On the example of the 2021 flood, it is shown that protective measures in the Amur Region after the catastrophic flood of 2013 helped reduce damage. However, there is still a high probability of recurrence of floods. Floods lead to the loss of personal property of the population, damage to transport infrastructure, agriculture in the regions, which reduces the quality of life of the population in the Far Eastern regions. Based on open damage data for 2021, it is shown that higher flood damage per capita is observed in regions with lower population density. The natural and social aspects of floods are reflected in their causes and consequences. It is shown that the anthropogenic causes of floods are largely associated with the expansion of economic activity. Despite the wide range and volume of financial support for the regions, for the population, the total amount of compensation in case of damage cannot compensate for all their financial losses. One of the options for reducing damage is considered the possibility of developing a program for the resettlement of the population from areas located in the flood zone.

The border zones that have formed in the Russian-Chinese border area are considered. The socio-economic indicators of the border regions of Russia and the People's Republic of China are considered, and the influence of transboundary regional formation on the development of less developed regions of both countries is noted. The formed border zones on the border of Russia and China are identified, their joint activities are analyzed, as well as attracting investments for further development. As a result of the study, the history of border relations between Russia and China was reviewed, tourism policy in cross-border regions and its priority areas were considered, a comparative evaluation of the socio-economic development of the Russian-Chinese border was made, cross-border regions formed on the border of Russia and China were identified. In the course of the study, possible ways for the development of the border zones of Russia and China were identified, and their impact on the socio-economic development of the regions of both countries was assessed: from China – Xinjiang Uygur Autonomous Region, Heilongjiang Province, Inner Mongolia, Jilin Province, from Russia – Primorsky Territory, Khabarovsk Territory, Jewish Autonomous Region, Amur Region, Zabaikalsky Territory, Republic of Altai.

Bronchopulmonary dysplasia in children of the Amur region: the structure of the disease

Aim. Analysis of the structure of bronchopulmonary dysplasia (BPD) in children of the Amur region at the stage of medical care in outpatient and inpatient conditions of the Research Institute of MCP for the period from 20102021.Materials and methods. The study used a retrospective analysis of outpatient records and medical histories of 146 patients with BPD aged from 1 month to 13 years.Results. Among children with BPD, boys accounted for 56.6%, girls 44.3%. Preterm infants accounted for 84.9%, full-term babies – 15.1%. The classic form of the disease was diagnosed in 56% of children, the new form – in 44%. Since 2013, there has been a decrease in the frequency of occurrence of the classical form (in 2011 – 100%, in 2021 – 0%). The opposite pattern is typical for the new form (in 2010 – 14.3%, in 2021 − 100%). Since 2018, there has been a tendency for the new form to prevail over the classical form. Concomitant pathology of the respiratory system was diagnosed in 40.2% of patients (5.03% of them were malformations, stridor – 33.3%, their combination – 1.9%), and pathology of the cardiovascular system in 3.8% of cases.Conclusion. The assessment and dynamics of the structure of BPD disease in the Amur region at the present stage is presented. We report the predominance of a new form of BPD over the classical one. The study noted the frequency of concomitant pathology on the part of the respiratory and circulatory systems in children with BPD. The identified features will be used to search for risk factors for the development and prognosis of this pathology.

The results of the study of multiple selections in a breeding nursery when creating new soybean varieties

Relevance. At the present stage for agricultural production, the creation of new domestic competitive varieties of various plants is of paramount importance within the framework of the large-scale program of the Russian Federation for import substitution, while one of the most important and sought-after crops in Russia is soybean.Methods. The material for the research was the hybrid populations F7-F17 generations of the breeding nursery (SP), which is annually replenished with selections of individual plants from the F6 hybrid nursery.Results. An estimate of the duration of multiple selections by the pedigry method in a breeding nursery (SP) until obtaining homozygous lines is given. The analysis of the conducted studies showed that out of 29 soybean varieties of hybrid origin included in the State Register of Breeding Achievements of the Russian Federation and being tested for 2023, 13 varieties (Harmoniya, Lydia, Nega 1, MK-100, Lebedushka, Zhuravushka, Lacemaker, Cinderella, Tisey, Lyana, Olimp, Lastochka, Tatiana) (44.8%) were obtained on the basis of multiple selections F7-F9 in the breeding nursery, and the variety Persona, which is included in the State Register for 11 regions and is in demand in the Amur Region, was isolated from the hybrid population of the F17 generation. As a result of the assessment for 2020–2022. F7-F17 generations of the breeding nursery according to the duration of splitting in hybrid populations, it was found that multiple selection up to the tenth generation is most effective (F7 — 35.1%, F8 — 30.8%, F9 — 12.1%), but promising highly productive lines with economically valuable traits can also be obtained from later generations

Influence of the use of liquid fertilizers on the quality indicators of grain of the spring wheat variety DalGAU 1

Relevance. Recently, liquid fertilizers have been increasingly used in the technology of cultivating spring wheat. They are ideal for spraying on the surface of a field with cereals and other plants. Compared to solid fertilizers, the advantages of automated control of their distribution over the field, the possibility of joint application of herbicides, insecticides, microelements.Methods. Field experiments to study the influence of methods of using liquid fertilizers were conducted at the experimental field of the Far Eastern State Agricultural University in the southern agricultural district of the Amur region (Blagoveshchensk district, village of Gribskoye). The laying of the field experience was carried out according to the method of B.A. Dospekhov in fourfold repetition. The registered area of the plot is 16 m², the placement is randomized, the previous crop is soy. The studies included field and laboratory observations.Results. It was found that when using liquid fertilizers, the weight of 1000 seeds changed according to the variants of the experiment with the use of fertilizers relative to the control without the use of fertilizers from 1.5 to 4.9 g. Сombined use of Nertus Start and Photosynthesis — 696.6 g/l, which is higher than the control by 48.7 g/l and the background by 19.2 g/l. The maximum value of the natural grain weight for an average of four years was in the variant with the combined use of Nertus Start and Photosynthesis — 696.6 g/l, which is higher than the control (by 48.7 g/l) and background (by 19.2 g/l).

Из истории Благовещенского государственного педагогического института в первое послевоенное десятилетие

The Great Patriotic War had a serious impact on the functioning of higher educational institutions of the country. Immediately after its end, most of them began to organize the educational process in difficult social conditions, characterized by a shortage of teaching staff and educational literature. The article is focused on the descrip-tion of the history of the Blagoveshchensk State Pedagogical Institute in the first post-war decade. Based on archival data and compilation of information about the history of the institute, obtained from disparate publica-tions, the main characteristics of the institute of that period are revealed: its structure, dynamics of the number of students, approaches to the organization of the educational process, strengthening and expansion of the teaching staff. Against the background of analyzing the process of transition of the university to peacetime ac-tivities, both negative and positive results of this period are noted. Conclusion dwells upon the fact that the Bla-goveshchensk State Pedagogical Institute was able, by expanding the directions of teacher training and in-creasing the number of applicants and graduates, to partially solve the problem of providing teachers for schools in the Amur region and the Far East.

Cropland Mapping Using Sentinel-1 Data in the Southern Part of the Russian Far East.

Crop identification is one of the most important tasks in digital farming. The use of remote sensing data makes it possible to clarify the boundaries of fields and identify fallow land. This study considered the possibility of using the seasonal variation in the Dual-polarization Radar Vegetation Index (DpRVI), which was calculated based on data acquired by the Sentinel-1B satellite between May and October 2021, as the main characteristic. Radar images of the Khabarovskiy District of the Khabarovsk Territory, as well as those of the Arkharinskiy, Ivanovskiy, and Oktyabrskiy districts in the Amur Region (Russian Far East), were obtained and processed. The identifiable classes were soybean and oat crops, as well as fallow land. Classification was carried out using the Support Vector Machines, Quadratic Discriminant Analysis (QDA), and Random Forest (RF) algorithms. The training (848 ha) and test (364 ha) samples were located in Khabarovskiy District. The best overall accuracy on the test set (82.0%) was achieved using RF. Classification accuracy at the field level was 79%. When using the QDA classifier on cropland in the Amur Region (2324 ha), the overall classification accuracy was 83.1% (F1 was 0.86 for soybean, 0.84 for fallow, and 0.79 for oat). Application of the Radar Vegetation Index (RVI) and VV/VH ratio enabled an overall classification accuracy in the Amur region of 74.9% and 74.6%, respectively. Thus, using DpRVI allowed us to achieve greater performance compared to other SAR data, and it can be used to identify crops in the south of the Far East and serve as the basis for the automatic classification of cropland.

GENOTYPIC VARIABILITY OF ACER NEGUNDO L. ALONG THE TRANS-SIBERIAN RAILWAY

The study of intraspecific variability of alien plants is crucial for revealing the patterns of their microevolution in the secondary distribution range and predicting the possibility of further dispersal and the ability to invade natural plant communities. It is still unclear how a genetically impoverished initial invasive population forms a taxon with a range exceeding the natural range of the species and, therefore, adapted to more diverse ecological and climatic conditions. Boxelder, Acer negundo L., is a remarkable object of study in this respect. The secondary distribution range of this North American species covers all regions of our plane excluding Antarctica. In Russia it spread from Kaliningrad to Vladivostok, formed invasive populations in all eight Federal Districts and was included in the TOP 100 of the most aggressive invasive species of the country. The intraspecific variability of its biomorphological characters was studied by us earlier, and the results of the study of genotypic variability are presented in this article. Invasive populations of A. negundo located along the Trans-Siberian Railway from Moscow to Vladivostok (9288 km) were examined. We isolated DNA from 38 specimens collected along the Trans-Siberian railway in Vladimir and Kostroma Regions, Republic of Tatarstan, Perm Region, Novosibirsk Region, Krasnoyarsk Territory, Amur Region, and Primorskii Territory. By the ITS 1-2 nuclear DNA site, specimens of Acer negundo from the Russian part of the secondary distribution range showed very high similarity with each other, but with 100% bootstrap support separated from specimens from the natural distribution range. According to the chloroplast high-variable trnL-trnF site, the specimens were divided into two clades that weakly correlated with the geographical origin of the specimen. Separate subclades with high bootstrap support are formed by the plants: 1) from Tatarstan (Kazan and Nizhnekamsk), 2) from Perm and Novosibirsk, and 3) samples from Krasnoyarsk. The haplotype network constructed at the trnL-trnF site also demonstrated the genetic specificity of the samples from Tatarstan. We hypothesized that only a few genotypes of A. negundo with a high degree of invasive activity were dispersed along the Trans-Siberian Railway (and possibly throughout all Russia). Other genotypes, including those that entered the territory of the former Russian Empire earlier, have not shown the ability to invade natural plant communities and occur rather rarely.

TO THE BIOLOGY OF SOME SPECIES OF HAWK MOTHS (LIPIDOPTERA: SPHINGIDAE) IN KHABAROVSKY KRAI

New information about the features of the biology of three species of hawk moths (Sphecodina caudata, Callambulyx tatarinovii and Hyloicus morio) is presented, as well as the preimaginal stages based on materials from the Amur region are illustrated.

Педагогические династии Амурской области: династия Панкрац

The aim of the study is to expand on the historical and pedagogical knowledge about the pedagogical dynasty of the Pankratz family, whose representatives carry out their professional activities in the Amur region. The paper provides information about the professional activities undertaken by the representatives of the pedagogical dynasty of the Pankratz family, specifies its features and type. The relevance of the study is determined by the need of society to master the professional experience transmitted by pedagogical dynasties, as well as the desire of the state to increase the prestige of the teaching profession and the quality of teacher education. The scientific novelty of the study lies in enriching historical and pedagogical scientific knowledge with the information about the Pankratz dynasty, which will allow it to be included in the unified database of pedagogical dynasties of the Amur region. As a result, it has been proved that the pedagogical dynasty of the Pankratz family possesses the features of pedagogical dynasties and is characterised as mature, multi-generational, average in composition, mixed by the type of intra-family ties, specialisation and level of education. From generation to generation, the representatives of the dynasty share and transmit their accumulated professional experience, ideals, moral values and traditions to the cultural space, which makes this dynasty socially significant.

Pennisetum rich. in the plant collection of the Amur branch of the Botanical Garden−institute

The article presents the results of assessing the decorative qualities of plants of the genus Pennisetum Rich. in the collection of the AB BGI FEB RAS. The studied cultivars showed differences in plant height and ear length. The height and size of the inflorescences directly depend on the meteorological conditions prevailing during the years of growing plants. The highest quantitative indicators of plant height were noted in the varieties 'Majestic Purple' and 'Purple Candles'. 'Purple Majesty' plants grow taller in containers than outdoors. The color of the vegetative parts of plants and inflorescences declared by the manufacturer for six varieties of Pennisetum glaucum L. did not correspond to the variety description. Variety 'Jade Princess', in comparison with other varieties, has a bright yellowish-green color of the leaves and burgundy-brown color of the inflorescences. In cultivar P. glaucum «Majestic Violet», splitting of varietal traits was observed in terms of the color of the vegetative parts of plants and the ear. The total duration of vegetation for all varieties of P. glaucum ranged from 189 to 211 days. Plant height in Pennisetum orientale Rich. regardless of the method of cultivation (open/ closed ground) varied insignificantly. The earliest flowering phase in outdoor cultivation was Pennisetum villosum Fresen. Pennisetum alopecuroides (L.) Spreng. late entry into the heading and flowering phase was noted, regardless of the method of cultivation. The highest quantitative indicators (plant height/ear length) among the studied species were found in Pennisetum setauceum (Forssk.) Chiov. According to the research results, P. setauceum and P. villosum can be attributed to the number of promising species for growing in the conditions of the south of the Amur Region. These species go through all phases of development and form full-fledged seeds; when grown in a container culture, they do not lose their decorative effect throughout the season.
