Colectarea și evaluarea diversității genetice conservate on farm în Republica Moldova
Get PDFThe need to collect plant genetic resources of some crops with importance in a healthy nutrition of the population is of major interest to our institution. The link between agriculture and food security is vital and of strategic importance to any country. In this equation, access and use of a rich genetic background, with known properties, is a condition, almost mandatory, which will allow a quick adaptation to the changes and trends that appear in the agro-food sector. Within this collecting mission, 15 rural communities, with a certain degree of isolation along the Prut River were explored, diversified from the pedoclimatic, altitudinal and agricultural systems point of view. It were targeted individual households of farmers with limited financial resources, who practice a low input agriculture. It were identified traditional varieties of vegetables and it were collected 116 local varieties, comprising 30 species, which will be able to be used in breeding programs or direct cultivation by farmers.All these local landraces with a great genetic variability were collected from local farmers, who prefer and grow them in their gardens due to the multiple uses in food and the adaptation to biotic and abiotic stress factors, in the context of current climate changes
Evaluarea expresivitatii fenotipice si biochimice la genotipurile de Lavanda spp. ameliorate si conservate la PGRB Buzău
No full textLavanda spp. belongs to the Lamiaceae family and has its center of origin in the Mediterranean basin, where it was first cultivated and then spread to England and the rest of Europe. Lavender was initially used for ornamental purposes, and later medicinal properties were discovered, especially in the oil extracted from the plant. The aim of the present work is the phenotypic and biochemical characterization of 6 improved lavender genotypes from the core collection held and conserved by the Plant Genetic Resource Bank Buzau. The germplasm collection includes 42 genotypes, 8 of which are genetically stabilized. Following the evaluation of phenotypic expression, biochemical analyses were performed to determine the chemical composition of lavender volatile oil extracted from plant material by hydro distillation. Chemical compounds were identified using mass spectrophotometric method and gas chromatographic analysis. The G2 genotype belonging to Lavanda angustifolia has been shown to have superior phenotypic and biochemical qualities and is expected to be approved and patented in 2023
Distribution and pathways of introduction of invasive alien plant species in Romania
Get PDFBiological invasions are one of the main drivers of modern human-induced species losses. Research on the
distribution of alien species and their pathways of introduction is essential for understanding and tackling
the invasion process. A comprehensive overview on invasive alien plant (IAP) species in Romania is lacking.
With this paper, we aim to contribute to filling this gap and to provide a visualization of national
patterns regarding plant species invasions, geographical origins and pathways of introductions. Based on
plant species occurrence records in the published literature and herbaria we compiled a national database
of 102 invasive and potentially invasive alien plant species. We georeferenced 42776 IAP species occurrences
and performed an analysis of their spatial patterns. The spatial analyses revealed a biased sampling,
with clear hotspots of increased sampling efforts around urban areas. We used chord diagrams to visualize
the pathway of introduction and geographical origins of the IAP species, which revealed that species in
Romania originate mainly in North and Central America, while the dominant pathway of plant introduction
was horticulture. Our results provide an important baseline in drafting management and action
plans, as invasive alien plant species represent a priority for the European Union through the Biodiversity
Strategy for 2030, and a good starting point for various analyses as the database is further developed and
regularly updated
Performante de productie la quinoa pentru frunze sub influenta irigarii si fertilizarii
Get PDFQuinoa (Chenopodium quinoa sp.) is a pseudo-cereal native to South America, known mainly for seeds. In recent years, studies and research have begun to be done on leaves, as it is known that in the area of origin, some local populations used as vegetables. The aim of the research is to evaluate the effect of fertilization and irrigation on the growth and development of two quinoa varieties (Vikinga and Puno), in order to introduce them on the Romanian economic market. The experience was organized in vegetation pots, in 42 variants, in the greenhouse. The obtained results show that the species is suitable for cultivation in protected areas, under the influence of factors: variety, fertilization and irrigation. The highest amount of leafy mass was obtained by Vikinga variety under biological fertilization irrigated with 75% of water from soil capacity (SC) positively correlated with the leaf area and the number of leaves. The irrigation with a rate of 75 % of the field capacity obtained the best results, compared to the regimes of 50 % and 100 % of the soil capacity
Platelet-rich plasma in animal reproductive medicine: Prospective and applications
No full textPlatelet-rich plasma (PRP) is the fraction of the plasma enriched with a platelet level above baseline, and it plays an essential role in tissue regeneration. The attention to PRP as unconventional therapy has increased during the past two decades. In animals, applications of PRP showed various degrees of success in a wide range of medical applications, from musculoskeletal injuries to ovarian insufficiency. Therapeutic applications with PRP in farm animals are still scarce, but the promising results offered by several studies are expected to trigger more interest in its application by both veterinarians and farmers. In this review, we highlight some efforts made in the field of animal reproduction regarding the use of PRP to potentiate the ovarian hypofunction, treat endometritis, improve the follicular development, oocyte competence and uterine environment for embryo implantation as well as restore testicular and erectile function in male, and as a treatment for mastitis
Evaluarea fenotipică a unor soiuri și populații locale de fasole pentru păstăi cu creștere determinată
Get PDFThe study aims to know the breeding potential of some varieties and local populations of dwarf french beans. Three varieties with green pods (Cape, Valja and Atlantic), one variety with yellow pods (Galbena de Moldova) and two local populations with pods green, collected from local growers near the city of Iași. At a preliminary multiplication of the seeds and testing of the culinary value of the pods, it was observed that the pods have a culinary value appreciated by consumers, and in the field a rather pronounced variability of some quantitative characters was externalized. Under these conditions, a field experience was carried out, with the aim of being able to evaluate the average values and the variability of the quantitative characters of the tested cultivars, possibly to be able to select some biotypes with breeding value
Detection of Phenuiviridae, Chuviridae Members, and a Novel Quaranjavirus in Hard Ticks From Danube Delta
No full textTicks are involved in the transmission of various pathogens and several tick-borne diseases cause significant problems for the health of humans and livestock. The members of the Quaranjavirus genus are mainly associated with argas ticks but recent studies demonstrated the presence of novel quaranjaviruses-like in ixodid ticks. In 2020, 169 Rhipicephalus sanguineus ticks were collected in Southern Romania from small ruminants and analyzed by high-throughput transcriptome sequencing. Among the viral families that infect Romanian ticks, we have identified sequences from Phenuiviridae (Brown dog tick phlebovirus 1 [BDTPV1] and Brown dog tick phlebovirus 2 [BDTPV2]) and Chuviridae families (Cataloi mivirus [CTMV]), and numerous sequences from a new quaranjavirus-like, tentatively named Cataloi tick quaranjavirus (CTQV). Phylogenetic analyses performed on the five segments show that CTQV is phylogenetically positioned within a clade that encompasses Ixodidae-borne viruses associated with iguanas, small ruminants, seabirds, and penguins distributed across different geographical areas. Furthermore, CTQV is positioned differently depending on the segment considered. This is the first report on the detection of a quaranjavirus-like in Eastern Europe. Further investigations are needed to discern its infectivity and pathogenicity against vertebrates
O analiză statistică comparativă a profilului antropometric între două echipe de volei feminin
Get PDFIn this work, a comparison from a mathematical and statistical point of view of the somatic qualities is attempted of volleyball players from two female teams aged between 12 and 16 years. It highlights the similarities or differences in the values recorded following the anthropometric measurements. Currently, the execution speed, explosive force and reaction speed are increasing during the volleyball game and it is necessary to train specific anatomical segments required for the execution of the technical elements necessary to perform the attack during the volleyball game. It is important to compare the height, height with raised arms or the arm span in players from two teams who want to achieve performances in the volleyball competitions organized by Romania Volleyball Federation. Fisher and Student tests will be used for comparative analysis of the somatic qualities of the players. The findings of the present study indicate that the anthropometric profile of players from Team CVH Junior Iasi is significantly better than that of the team CSS Botoșani
Design of GNSS networks for monitoring earth dams deformations
No full textThe paper presents a series of
results regarding the application of GNSS
technology for measuring displacements to
earth dams. An appropriate horizontal and
vertical deformation-tracking network must
be established for the rapid monitoring of
earthmoving movements. Data obtained from
the monitoring network can be used in the
earth dam stability analysis program. Periodic
tracking of earth dams using GNSS
technology provides high accuracy of spatial
distortions. The results of the paper show the
application of GNSS technology to monitor
the deformations of the Podisu earth dam
located on the Sheep Valley River in Iasi
County. In the first stage of research (2019
and 2020), the local geodetic tracking
network was created. To monitor the dam,
four control landmarks were placed on the
crest of dam and seven landmarks on the
downstream slope. In the second stage of the
research (year 2021) the measurements of
the displacements at the earth dam were
performed. The GNSS monitoring method
has the advantage of positioning the target
quickly, statically, and with high accuracy.
The measurements used fixed stations
located at two points in the local geodetic
network. Four Trimble GNSS receivers were
used for the measurements. The resulting
data was processed using the Trimble
Business Centre program. The obtained
results were analysed in comparison with
those existing in the design documentation
and technical expertise of the dam. The
results highlight the presence of
displacements on the crest of a dam and
slopes of the dam. The final findings
highlight the performance of GNSS
technology in the monitoring process, where
it provides millimetre-accurate accuracy
with high spatial and temporal accuracy

No full textThis study aims to determine the differences in skull between Asian and golden palm civets by geometric morphometric method. The landmarks were marked on these photographs, and principal component, classical cluster and canonical variance analyses were performed. The method of geometric morphometry of the skull is a powerful tool used to differentiate the species. Fourteen and 20 homologous landmarks were marked using tpsutil and tpsdig2 programs on the frontal and palatinal directional photographs, respectively. As a result of the study, the first principal component (PC1) accounted for 33.586% on the frontal view, 41.602% on the palatinal view of the total shape differences, respectively. Distinctive differences on the frontal and palatinal view were observed in the caudal, rostrolateral and the last molars and the caudal palatine, respectively
