“Out of Love for You”
Authors: Upham Tonicha Mae
Published: November 2024

This article approaches gender and power through the study of emotion as a means of refreshing and updating the study of Rūs gender using Arabic geographical sources. Considering Arabic geographical and historical sources on the Rūs that deal with the concept of funerary sacrifice, in particular those that posit the possibility of male as well as female sacrificial victims, I examine the conditions attached to the practice of sacrificing men in these sources. I do so primarily by focusing on the semantic usages of ḥubb (love) as it relates to the Rūs, exploring the potential for wider emotional exploration within geographical discussions of the Rūs and in the context of their use by researchers today.

Published: November 2024

Traumatismo aórtico contuso (BAT) é uma condição rara, porém crítica, na medicina de emergência, com alta taxa de mortalidade entre 75% e 90%. Esse trauma geralmente resulta de impactos de alta energia, como acidentes de carro, quedas de grandes alturas ou trauma torácico grave, causando danos significativos à aorta, incluindo lacerações, dissecções, hematomas intramurais ou até mesmo ruptura aórtica completa. Tecnologias avançadas de imagem, como tomografia computadorizada (TC) e ecocardiografia transesofágica, melhoraram recentemente a precisão do diagnóstico de lesões aórticas, especialmente em pacientes hemodinamicamente instáveis. O tratamento ideal para BAT, no entanto, continua sendo um tópico de debate. Embora o reparo endovascular seja geralmente preferido devido aos menores riscos do procedimento e melhores resultados a longo prazo, a cirurgia aberta ainda é recomendada em casos específicos, principalmente quando a lesão é extensa ou localizada em áreas críticas da aorta, como o arco aórtico. Este relato de caso discute as decisões clínicas para um paciente com trauma aórtico contuso, detalhando a escolha de cirurgia aberta e explorando os desafios do tratamento pós-operatório. Nosso objetivo é contribuir para a literatura existente, fornecendo insights e recomendações que podem auxiliar os profissionais de saúde no tratamento de casos semelhantes.

Authors: Skovlund Sebastian Venge , Østergaard Mark Skovbye Eg , Seeberg Karina GV , Suetta Charlotte , Aagaard Per , Andersen Lars Louis , Sundstrup Emil
Published: November 2024

OBJECTIVE: Knee pain is highly prevalent and disabling among the general and working population. This systematic review explored the effectiveness of workplace-based interventions on knee pain among workers.

METHODS: A PICO-guided systematic search was performed in PubMed and Web of Science Core Collection for articles published from 2003 until January 2023. Eligible articles included randomized and non-randomized controlled trials assessing the effect of workplace-based interventions on knee pain among currently employed adult workers. The quality assessment and evidence synthesis adhered to the systematic review approach, which the Institute for Work & Health developed, and was focused on developing practical recommendations for stakeholders.

RESULTS: Of the 13 identified studies, 11 medium- and high-quality studies were entered into the evidence synthesis. Importantly, none of the included studies specifically aimed at reducing of knee pain. Still, among the included studies, a strong level of evidence suggested no benefit of workplace-based physical exercise/activity intervention on knee pain. The level of evidence was deemed too uncertain to guide current policy/practices for ergonomic and multifaceted interventions. No intervention types were associated with negative effects on knee pain.

CONCLUSIONS: The current evidence-base pertaining to workplace-based prevention and management of knee pain is insufficient to guide effective preventive workplace practice or policy development. Considering the global prevalence and health impact of knee pain, development and implementation of effective workplace interventions aimed at prevention and management of knee pain is needed.
ENZIMAS DO SISTEMA PURINÉRGICO EM INFECÇÕES PARASITÁRIAS: INSIGHTS SOBRE A PATOGÊNESE E PROGNÓSTICO
Authors: Doleski Pedro Henrique , Friedrichs Douglas Gonçalves
Published: November 2024

As infecções parasitárias são encontradas em todo o mundo e causam sérios problemas sociais e econômicos, afetando a saúde pública. Infecções por parasitas protozoários (como Toxoplasma gondii e Trypanosoma cruzi) e trematódeos (como Fasciola hepatica e Eurytrema coelomaticum) interagem com a sistemas fisiológicos do hospedeiro, como por exemplo a sinalização purinérgica. Nas infecções parasitárias citadas, destacamos as modificações na atividade das enzimas NTPDase, 5´nucleotidase (5´N) e adenosina desaminase (ADA). Na infecção por Toxoplasma gondii, observa-se um aumento da NTPDase e 5'NT no tecido esplênico de camundongos. Já na infecção por Trypanosoma cruzi observa-se aumento na atividade da E-NTPDase em linfócitos isolados de camundongos. Tais elevações podem ser um evento compensatório no qual se eleva a sinalização adenosinérgica. Por outro lado, a infecção por Fasciola hepatica em ratos exibe uma modulação complexa dessas enzimas ao longo das fases da infecção, com aumento da NTPDase na fase aguda e aumento de ambas enzimas na fase crônica. Eurytrema coelomaticum, por sua vez, apresentou aumento significativo da NTPDase sérica, a qual está correlacionada com a gravidade da infecção (prognóstico). Esses achados demonstram que as infecções parasitárias induzem modulações na sinalização purinérgica dos hospedeiros, e estão relacionadas com a patogênese. Além disso, a atividade destas enzimas pode apresentar valor no prognóstico das infecções parasitárias, como também novas estratégias terapêuticas para o tratamento de tais patologias.
Spatial Violence of the “Halls” in Old English and Old Norse Poetry
Authors: Ms. Sreeja Chowdhury
Published: November 2024

In the recent years, the scholarship of Urban Space has primarily focussed on the postmodernist discourse, but this essay, by connecting the Anglo-Saxon and Old Norse culture, takes up the subject of early mediaeval literature and the narrative of violence in urban spatial discourse. A leitmotif that keeps on figuring in Old English and Old Norse poetry is that of the ‘hall’ - a transcultural conjunctive space for transaction or exchange of both material goods such as fighting men, treasure and the like, and the non-material items such as martial honour, power, comradeship and the like. Though such a space easily seems to be a dispositif heterotopia, this essay explores how its (non-crisis) heterotopic motif, with the true manifestation of the ‘hetero’- an encapsulation of the ‘diversity of an emplacement of a cityscape’, is ruptured by an unmasking of violence that is ironically disrupting this trans-culturalism yet uniting the heteroglossic discourses by dominating this space. The space of Gunnarr and Högni’s hall and Heorot are both equally stained with the blood of the unjustly slaughtered victims: the murder of Gunnarr and Högni by Atli in the former case, and the murder Hrothgar’s men by Grendel’s mother in the latter case. Murder and bloodlust, the polarised ‘evil’ or ‘othered’ character(s) not only unite the literary space of these two tales but also unite the cultural space of the Danes and the Anglo-Saxons, through the metaphor of the ‘hall’. This is reinforced by the fact that the disruptive force of revenge in both cases takes place ‘outside’ the halls, ‘the area of unity’: in the former case, Guðrún does not burn Atli in the hall but kills him outside and buries him, and in the latter case, in the ‘den’ where Beowulf ventures to battle and kill the monster. Therefore, this paper attempts to explore how the othered discourse of violence actually assumes the central role and problematizes the narrative of dispositif heterotopia through the spatial metaphor of ‘hall’, a miniature cityscape, by acting as a both uniting and disrupting force.
Urban Landscape in Paul Lynch’s The Prophet Song: Power, Surveillance, Resistance
Authors: Mr. Rahul Kherwa
Published: November 2024

This paper explores how Paul Lynch’s The Prophet Song portrays issues vis-à-vis surveillance, escape and resistance in urban landscapes. The dystopian novel envisions futuristic society wherein existing democratic government attempts to control citizens by using surveillance technologies, whereas, characters in the novel try to resist and escape from the totalitarian venture. The novel is a cautionary tale depicting civil liberties being destroyed in urban spaces by these technologies so raising questions of surveillance ethics. The paper attempts to study power dynamics in urban landscapes using Foucault’s notion of disciplinary power, surveillance and resistance provide crucial insights into the novel’s depiction of social control and resistance. The paper offers a perspective to re-think about structures of power dynamics and search for agency in urban landscape.
Jürgen Habermas and the Critique of the Urban Subcultures of Subversion and Resistance
Authors: Gurjeet Singh  , Dr Vipan Pal Singh
Published: November 2024

The Frankfurt School thinkers are concerned with practical aspects of the society that contribute to domination and subversion of masses not just through visible forces but also through subtle propaganda. The aim of these thinkers is to understand the modus-operandi of this subversion and to suggest ways of resisting this domination. Being a major thinker of the School, Jürgen Habermas critiqued a vast number of aspects that also include several issues related to urban subcultures. Habermas’s basic objective behind these critiques is to understand the modus-operandi of social domination and to suggest ways of emancipation and resisting the subversion. This paper is aimed at understanding the ways in which urban subcultures are related with issues pertaining to subversion and control and how they can be used as tools for resistance and human emancipation. For this, the paper evaluates the views of Jürgen Habermas regarding European Urban Subcultures including but not limited to Art and Music Performances, Radio and Television, Professional Subcultures, and the inherent qualities of these subcultures for understanding the role of these subcultures viz a viz social subversion and resistance.

Low temperature testing of soybean lines
Authors: Malii Aliona
Published: November 2024

The experiments were carried out with the aim of testing under climate chamber conditi-ons at low positive temperatures (+4˚С, +8˚С) and the optimal temperature (+25˚С) of soybean lines obtained by experimental mutagenesis (γ rays) to select genotypes capable of germinating under low temperature conditions that are recorded in the Republic of Moldova at the end of march - beginning of april. Climate change in recent years is a global phenomenon with a direct impact on all agri-cultural crops. These climate changes are also felt in the territory of the Republic of Moldova, where the cultivation of spring crops is associated with a high risk due to regular droughts that leave their mark on the production of agricultural crops, leading to important harvest losses or the death of plants. In addition, due to climate warming in recent decades, the frequency, dura-tion and intensity of summer droughts are continuously increasing [1]. In the soybean crop, the most sensitive phase of the ontogenesis is the ﬁlling of the grain, which occurs in August - the driest period of the year, which often leads to incomplete ﬁlling of the seeds and a noticeable decrease in yield [2]. In order to avoid thermal and water stress conditions in critical moments (ﬂowering, grain ﬁlling), technological methods can be used through early sowing and the se-lection of genotypes from groups of lower maturity [3]. Germination and emergence of soybean seedlings of the vast majority of varieties are able to withstand only short-term frosts, up to minus 2 - 4 ˚С. In the Republic of Moldova, soybean sowing is recommended in the second half of April - the beginning of May. One of the ways to increase the proﬁtability of soybeans is to move the sowing dates to earlier and extra early dates (late winter - early spring). This requires varieties resistant to low temperatures, with an active development of plants in early spring against the background of low positive temperatu-res and to survive late spring frosts. An early sowing date for these varieties provides the basis for productivity, as it makes optimal use of the remaining soil moisture from the dry weather winter and allows them to ripen a month earlier than usual, eliminating August droughts [4]. At the same time, early sowing brings a series of advantages to the farmer, limiting their economic risks [5].
Applying accelerated aging method for assessing the long-term storage capacity of zucchini seeds (Cucurbita pepo l.)
Authors: Melian Lolita , Korlateanu L. , Mihăilă Victoria , Ganea Alina
Published: November 2024

The problem of long-term seed storage to preserve genetic diversity is an important aspect that attracts the attention of the scientiﬁc community. Recently, the threats of global climate change are increasing; in addition, there are a number of reasons leading to the loss of breeding material due to untimely reproduction for subjective and objective reasons. It is gene banks that provide the necessary conditions for seed storage for a long time. Plant genetic banks in various countries use the accelerated aging test on seeds of diﬀerent plant species to determine the storage potential of seeds. With the help of this method, it is possible to monitor the collection samples of plant gene pool, which contributes to the possibility of accounting changes in their viability. The accelerated seed aging test makes it possible to adequately model and predict the longevity of seed storage, to assess the diﬀerences in aging resistance between varieties of diﬀerent crop species. The prediction obtained by this method correlates well with the ﬁeld germination of seeds. This is especially important for determi-ning the timing of reproduction of active collections in plant genetic banks. The method of accelerated aging consists in incubating seeds under conditions of elevated temperature (40-440 C) and humidity (90-100%), and the period of exposure of seeds to these factors depends on each speciﬁc crop and sometimes on the speciﬁc genotype [4]. The duration of combined exposure to these stressors (from 48 to 120 hours) and temperature values for determining the storage potential depend on the plant culture, so the most suitable aging environment must be determined for each species. Studies on the current methods of accelerated aging of seeds of pumpkin crops are very few, especially for zucchini crops. Some of the earlier studies have shown that optimal seed aging conditions vary considerably among pumpkin crop species, such as watermelon [1], melon [2, 5], pumpkin, and zucchini [3]. The aim of our research was to develop a method of accelerated aging to determine the storage potential of some zucchini collection varieties, including those obtained from the Pridnestrovian Research Institute of Agriculture for their subsequent storage in the gene bank.

It was shown high variability in the content of lycopene and β-carotene in genotypes studied, which made it possible to diﬀerentiate them into separate clusters and identify those with the highest content of carotenoid pigments. Varieties Ruﬁna and Flacăra, as well as lines L 302, L 404, L 406, L 408, L 410, as the most valuable genotypes, can be involved in the breeding process when creating new varieties with high taste properties.
The pest monitoring of heliothis armigera hbn. on the corn
Authors: Geletiuk O.
Published: November 2024

The purpose of this work was to highlight one of the ecological methods of seasonal monitoring of the population density of the pest cotton bollworm, Heliothis armigera Hbn. (Lepidoptera: Noctuidae) on corn. In recent years, this pest is a particularly acute problem in the agroecosystem plantati-ons of agricultural crops. The larvae of this pest cause essential damage to a wide spectrum of agricultural plants, including the corn, which in the Republic of Moldova is the part of the economically important crops. To protect the harvest, a wide spectrum of pesticides is appli-ed and about 3-4 chemical treatments are carried out annually. In the Republic of Moldova, the areas cultivated with sweet corn constitute approximately 3000 ha annually and are con-stantly growing. At the same time, chemical treatments, along with pest control, also cause signiﬁcant damage to the ecological system, which manifests itself not only through direct negative eﬀects, but also indirect ones, which will become visible in the coming years. The widespread use of pesticides also leads directly to the considerable reduction of the beneﬁcial insect species. Extremely important method for combating this pest is the seasonal monitoring of the population density depending on the species of cultivated plants and the phenological phases of their development. One of the eﬀective solutions would be the development of methods based on natural control mechanisms of the relationships between harmful organisms and cultivated plants. A safe method for detecting and monitoring the population density of this pest is the application of pheromonal traps. The most important advantage of using sexual pheromones is that they are biologically active substances characteristic only for the target species and are not harmful both to the human body and to the environment [1, 2].

Published: November 2024

Increasing the acreage of peas around the world is the main way to increase the produc-tion of vegetable protein to make up for its deﬁciency in human and animal nutrition [1, 2]. Vegetable varieties of peas (Pisum sativum L.) they form a separate group and are quite clearly separated from grain varieties by genotype [1]. The value of immature seeds (green peas) of ve-getable varieties of peas lies in the unique balanced content of essential amino acids, vitamins, biologically active substances, mineral salts [3, 4]. Currently, a special place in the technology of cultivation of agricultural crops is occupied by the use of biologically active substances of the steroid type. Steroid glycosides are seconda-ry metabolites of higher plants, consisting of a steroid aglycone and one or more sugar chains. Their pre-sowing treatment of seeds, especially with low viability, contributes to an increase in germination energy and germination, intensiﬁcation of initial growth processes, increased productivity, plant resistance to biotic and abiotic factors [5, 6, 7]. Moldstim biopreparation based on furostanolic glycoside capsicoside obtained from pepper seeds (Capsicum annum L.) is recommended for use in agriculture as a bioregulator. However, in relation to vegetable peas, its biological activity has not been studied, which was the purpose of this work.

In the technologies of creation of preparations with plant protective eﬀect against patho-genic agents, ecologically harmless, it is of great importance to identify the sources of plant raw material of compounds with antimicrobial eﬀect, the development of isolation systems of compounds and the screening of their activity. Higher plants produce hundreds of thousands of diﬀerent compounds with important biologi-cal, pharmacological and ecological roles that often present a safe way to defend against herbivo-rous insects, phytopathogenic microorganisms, causative agents of human diseases. In connection with this, crude plant extracts, puriﬁed and fractionally directed, are successfully used to create active principles with desired properties. It is estimated that there are about 2.5 million higher plant species, most of which have not yet been examined for their biological activities [4]. Some constituents of tea, especially green tea such as epigallocatechin gallate, epicate-chingallate, epigallocatechin and epicatechin are powerful antioxidants that help increase the body’s immunity. Data on the antibacterial activity (Escherichia coli, Listeria monocytogenes) of tea extracts are known, including green tea [1, 2]. Therefore, research in the ﬁeld of identiﬁcation and study of plant raw materials – sour-ces of bioactive compounds with curative and phytosanitary potential, are undeniably current, timely and of a major importance. Purpose: The aim of this research was to establish the antimicrobial activities of oxidized tannins isolated from black tea leaves, commercial green tea and pomegranate peels.

The effect of water stress on sesame (sesamum indicum l.) Samples from the m3 generation in the conditions of it’s artificial modeling
Authors: Mogîlda Anatolii
Published: November 2024

Sesame (Sesamum indicum L.) is one of the most important oil crops widely cultivated in diﬀerent regions of the world. For many centuries, sesame seeds have been used as a source of oil, protein, vitamins and minerals for human and animal nutrition [4]. Unlike other crops, sesame is considered to be more drought tolerant [5]. However, drought often occurs together with heat or high temperatures and signiﬁcantly aﬀects sesa-me production. Detrimental eﬀects on sesame seed production and quality are signiﬁcantly observed when water stress occurs, especially at the germination and ﬂowering stages [3]. Severe or prolonged drought negatively inﬂuences sesame productivity by reducing the num-ber of capsules per plant, yield and oil quality [1]. Drought stress can also aﬀect the level of secondary metabolites and morphophysiological characteristics of sesame seeds. Seed ger-mination is the ﬁrst critical and most sensitive stage of the plant life cycle [3] due to its direct and strong correlation with seedling establishment and early growth. As a result of climate change, there is an increased frequency of drought throughout the crop cycle, including the germination stage. Thus, there is a need to improve crop drought tolerance through breeding and selection of suitable germplasm to be used in the development of adapted cultivars that could enable sustai-nable and competitive sesame cultivation. This work was carried out with the aim of comparative testing of sesame samples obtained by the induced mutagenesis (Gy) method, after resistance to osmotic stress under the conditions of its experimental modeling by using the osmotically active substance PEG 6000.

Entomopathogenic fungi of the genus Beauveria (Hypocreales) are essential natural regulators of insect populations, characterized by their ability to infect a wide range of hosts, with an increased mortality rate. Using species of the genus Beauveria as biological control agents oﬀer numerous advantages, including high eﬃcacy, harmlessness, and compatibility with other IPM (Integrated Pest Management) methods, being considered among the most promising alternatives for pest control [1]. Beauveria genus has received considerable com-mercial attention in the last 30-35 years as a source of strains for the mass production of bi-opesticides. As a result, it has determined an increased interest in improving their properties and spectrum of use in biological control, driving numerous studies focused on investigating the supplementary beneﬁcial properties such as anti-phytopathogenic potential. Currently, Beauveria spp. are considered the most promising microorganisms for the development of complex biological control strategies, through their proﬁling as endophytes, plant growth promoters, beneﬁcial colonizers of the rhizosphere, and most importantly, in vitro, and in vivo antagonists of signiﬁcant plant pathogens [1]. As an outcome of the previously conducted research, native fungal strains of Beauveria spp. with the potential to be used as biological control agents were isolated and characterized. The strains of entomopathogenic fungi of the genus Beauveria show an intrinsic variability in their ability to inhibit or antagonistical-ly inﬂuence phytopathogen growth, development, and viability. Thus, the investigation and precise selection of the most eﬀective strains are required to develop biopesticides with the potential to be applied in complex biological control [4]. The work aimed to investigate the antagonistic properties of some local strains of fungi from the Beauveria genus for sub-sequent complex biological protection of crops.

Green areas are a special element of the urban environment. Trees are essential for healthy communities and people. The state, conservation and development prospects of plantations constitute a whole complex of diﬃcult and important scientiﬁc and practical problems. The complex of tree diseases is the most important factor of negative impact in urban plantations. Both infectious and non-infectious types of diseases can be found in green spaces. In park plantings, rot diseases and various infectious lesions of leaves dominate; while in street plantings, non-infectious leaf necrosis and necrosis-cancerous lesions of trunks and branches predominate. The goal of the study was to identify diseases of the most common to the urban area of Chisinau Norway maple (Acer platanoides) and to evaluate the eﬀectiveness of biological con-trol of powdery mildew using a consortium of microorganisms.

The evolution of agriculture records previously non-existent times, which in addition to the expansion of many technological developments, is dominated by the impact of many ecolo-gical problems [2]. Although permanent agriculture has been a signiﬁcant factor in inﬂuencing the environment, it still contains eﬀective levers to keep these issues at an acceptable level. The basis of these actions is represented by the natural mechanisms, currently frequently presen-ted in the functionality of regenerative agriculture, which in synergy with other paradigms of agriculture have diﬀerent abilities to work in complex and produce systemic eﬀects aimed at reducing the impact of environmental factors.

Assessment of collection maize lines’ resistance to drought and diseases
Authors: Bylici Еlena , Grăjdieru Cristina
Published: November 2024

A characteristic feature of the ontogenesis of higher plants is the great dependence of their phenotypic structure and functions on environmental conditions at such stages of organogenesis as diﬀerentiation of the growth cone, the beginning of ﬂower formation, preparation for game-togenesis, and the formation of male and female gametophytes[1]. In maize under moisture deﬁciency, the duration of the period between the end of cell division and the cessation of cell growth of styles increases signiﬁcantly, which leads to a lag in the development of stigmas. High temperature and low air humidity reduce the viability of pollen and negatively aﬀect the pollination and grain content of cobs [2]. Toxigenic fungi can infest maize at diﬀerent stages of ontogenesis and use pollen as na-tural vector to enter ears during silk emergence [3, 4]. Due to the quantitative nature of maize resistance to accumulation of the most hazardous micotoxins and its signiﬁcant dependence on external factors, breeding resistant genotypes proves to be an intricate task. No data regarding R genes associated with resistance to toxigenic Fusarium spp. and Aspergillus spp. is published. Therefore, ﬁeld trials to assess maize susceptibility to major fungal pathogens associated with mycotoxin contamination remains the most adequate strategy to fetch out the most perspective genotypes. Current study focuses on assessing the resistance to drought and susceptibility to fungi of certain maize genotypes at the generative stages of ontogenesis.

Cultivation and processing of aromatic and medicinal plants (AMP), to be used for maintaining and improving health, are in continuous development in our country. Research on the species Salvia sclarea L. and Lavandula angustifolia Mill, using modern methods, was initiated at the Research Station for Aromatic Plants and Essential Oils. Since 1996, research of major importance in the ﬁeld of genetics and breeding of aromatic and medicinal plants, as well as the creation of promising genotypes has been conducted at IGPPP. The cultivation of these species is particularly advantageous due to the cultivars of aromatic and medicinal plants that in droughty years produce higher amounts of good quality essential oil than in the years with normal amount of atmospheric precipitation. Our research was aimed at determining the best uses of aromatic and medicinal plants, the creation and evaluation of new genotypes of aromatic and medicinal plants, the development of cultivars and hybrids adapted to the climatic conditions of the Republic of Moldova, with superior characteristics not only from the point of view of productivity, but also of the quality of the raw material, of the essential oil, due to the high concentration of active principles; maintaining, reproducing and implementing new cultivars. Purpose. The importance of aromatic and medicinal plants is determined by the multiple uses of essential oils in medicine, perfumery, cosmetics, aromatherapy, food etc.; for this reason, research was focused on the diversiﬁcation of the initial breeding material, the improvement of the assortment of hybrids and cultivars. Genetics and breeding, as well as creation of new cultivars and hybrids is a continuous process. Each newly approved, patented cultivar is more eﬃcient than the previous ones.

Published: November 2024

Clove placement inﬂuences plant growth and development, as well as bulb mass forma-tion. Peripheral garlic cloves are distinguished by their superior quality compared to internal ones (mass ratio is 60: 40%). Studies have found that using cloves from diﬀerent locations wi-thout mass calibration for planting leads to diﬀerent bulb ripening times, which complicates the harvesting process and leads to a deterioration in garlic quality. Sorting, with the aim of using similarly ground garlic cloves for planting, ensures uniform plant development, along with bulb ripening and better quality products.

In long-term ex situ conservation of plant germplasm in genetic banks, the main task is to pre-serve the viability of the seeds, since as a result of aging the seeds gradually lose their germination capacity and genetic homogeneity [6]. Therefore, the study of the storage potential (SP) of seeds is a very important step for ex situ conservation of plant genetic resources, especially during long-term storage of collection accessions in a plant genetic bank. In recent years, the determination of this potential has been practiced in many plant genetic banks in diﬀerent countries [2, 4]. In order to study the storage potential, which indicates the longevity of collection samples during storage, the method of accelerated aging (AA) of seeds is of great interest, the essence of which consists in the artiﬁcial acceleration of aging by exposing seeds for a short time at elevated temperature and high relative humidity [1]. There are a number of studies that compared the physiological and biochemical changes in seeds during accelerated aging and long-term storage. Accelerated seed aging allows evaluating the diﬀerences between varieties of diﬀerent types of crops. With the help of the test, it is possible to monitor gene pool samples, i.e. to conduct a permanent record of seed viability and classify genotypes from working and active collections according to the parameters of AA. The test allows to: 1. Identify samples that are not suitable for long-term storage. 2. Give recommendations on the timing of seed reproduction. 3. Indicate the need to restore the viability of valuable collection samples. The aim of the research was to study the storage potential of to-mato collection samples according to various morphophysiological and biochemical parameters of seeds and seedlings after applying tests for accelerated aging of seeds and electrolyte leakage and to gradate genotypes for this complex trait before ex situ conservation.
