The degree of helminth infestation of the ecaudate amphibians depending on the biotic factors
Get PDFThe paper presents data on the identification of the helminth fauna structure of ecaudate amphibians depending on the
biotic factors. 133 specimens of ecaudata amphibians (Ranidae, Bufonidae) was studied from Central Forest (Codrii
Reservation, Ciuciuleni village) and in the natural ecosystem - the Dniester River, from the village of Talmaza from the
Stefan-Voda district. As result of helminthological investigations, it was established that the structure of the helminth
fauna of ecaudate amphibians species is characterized by 17 helminths species: Haematoloechus variegatus Rudolphi,
1819; Codonocephalus urniger Rudolphi, 1819; Opisthioglyphe ranae Froelich, 1791; Paralepoderma brumpti Buttner,
1951; Prosotocus confusus Looss, 1894; Tylodelphys excavata Rudolphi, 1803; Diplodiscus subclavatus Pallas, 1760;
Parastrigea robusta Szidat, 1928, Strigea falconis Szidat, 1928; Gorgodera varsoviensis Sinitzin, 1905; Haplometra
cylindracea Zeder, 1800; Pleurogenoides medians Olsson, 1876, Cosmocerca ornata Dujardin, 1845; Oswaldocruzia
filiformis Goeze, 1782; Icosiella neglecta Diesing, 1851; Spirocerca lupi Rudolphi, 1809; Acanthocephalus ranae
Schrank, 1788, which from a taxonomic point of view fall into 3 classes (Trematoda, Secernentea,
Palaeacanthocephala), 7 orders (Plagiorchiida, Echinostomida, Diplostomida, Ascaridida, Strongylida, Spirurida,
Echinorhynchida), 16 families (Omphalometridae, Haematoloechidae, Plagiorchiidae, Lecithodendriidae, Gorgoderidae,
Diplodiscidae, Diplostomatidae, Pleurogenidae, Diplodiscidae, Strigeidae, Macroderoididae, Cosmocercidae,
Molineidae, Onchocercidae, Spirocercidae, Echinorhynchidae) and 17 genera (Haematoloechus, Codonocephalus,
Opisthioglyphe, Paralepoderma, Prosotocus, Gorgodera, Tylodelphys, Diplodiscus, Parastrigea, Strigea, Haplometra,
Pleurogenoides, Cosmocerca, Oswaldocruzia, Icosiella, Spirocerca, Acanthocephalus). It was found that the diversity of
helminth fauna of the studied amphibians is structured depending on the host species, so the greatest diversity of
helminthes in amphibians in the family Ranidae was established in Rana ridibunda and Rana lessonae with 17 species,
and the lowest diversity in Rana dalmatina species - with 5 species of helminths, and for the species from the Bufonidae
family, no different values were established, so each species being infested with 3 species of helminthes. It was
determined that the helminth fauna of the amphibians investigated according to the age of the host shows divergent
values, so that in the juveniles of the Rana ridibunda species the infestation with only 4 species of helminthes was
established. The diversity and intensity of helminth infestation of ecaudate amphibians has been established
Fasciolosis, morphophysiological changes in ruminants
Get PDFThe article presents data of the level of infestation of adult cattle (4-6 years) and bulls (23-25 months) with Fasciola
hepatica in different periods of time and in households with different maintenance technologies. The results of
parasitological research carried out in households with various maintenance technologies of the Republic, during the
years 1986-1987, as well as after a large number of animals were redeployed from complexes and farms to private
households (2001-2002) demonstrated that adult cattle were infested with fasciola in 66.4% of cases, or by 35.8% more
than in the period of 1986-1987, and bulls - in 46.1% of cases, respectively by 30, 4% more. In order to establish the
nutritional value of muscle tissue and liver in cattle infested with fasciola, the content of vitamins A, E, B1, B2, C,
micro- and macroelements Ca, Mg, Na, K, Fe, P was determined and deviations were determined major in the content
of these indices. In the body of animals infested with fasciola, associations of highly pathogenic colibacilli,
staphylococci, streptococci, aerobic and anaerobic bacilli are formed, the synergistic pathogenic action of which causes
major modifications in the host's body, and in some cases even lethal conditions. Thus, in the primary infestation with
fasciolae metacercariae, the highest level of infection of the liver with aerobic bacteria (colibacilli, staphylococci,
streptococci) was established on the 60th day (the acute stage of the disease, young fasciolae actively migrate into the
liver parenchyma). Then the number of bacteria in the liver and bile gradually decreases, which is explained by the
immunological transformations that take place in the animal's body (the bactericidal activity of bile and the phagocytic
activity of neutrophils increases, as well as the concentration of specific antibodies against bacteria) and the significant
decrease in the rate of destruction of liver parenchyma by adult trematodes
The selection and evaluation of promising forms of Sesamum indicum L..
No full textSesame (Sesamum indicum L.) is a "historic" species recognized as an oleaginous and medicinal plant since over 5000
years ago. The works on its acclimatization started with 5 seed samples from India and 6 from Bulgaria, all of which
were included in the breeding process. The seed material obtained after crossings was subjected to "negative selection",
choosing the forms with the shortest growing season and high productivity under the climatic conditions of our region.
After six years of selection, a form that corresponded to the initial requirements was obtained. The comparative crops
tests (CCT) conducted over several years confirmed the superiority of the selected form by high productivity of 1.2-
1.5 t/ha and oil content of 55.4%, making it possible to register it in the National Register as a cultivar with the name
‘Deliciu’, which is still used by Moldovan farmers. The breeding has continued, in order to obtain cultivars with
capsules that ripen simultaneously and do not open before harvesting, another cultivar, which is undergoing CCT
testing, was chosen by the method of repeated selections. The new cultivar reaches a height of about 125-127 cm, which
contributes to the facilitation of mechanized harvesting, with a production potential of 1.4-1.8 t/ha, the content of fatty
oil 60.3% and the duration of the growing season of 132-138 days. Thus, as a result of the selection, the sesame crop
was included in the agricultural production as a source of aromatic plant oil, and the seeds being a food additive with
high content of Ca, Fe, Zn, Mg, P, Cu vitamins and minerals
Research on changes in pork quality parameters following different aging processes
Get PDFThe present study aimed to investigate the effect of aging time and method on the quality characteristics of three
categories of domestic pork muscle (pork loin, collar and leg). The meat samples were evaluated at three aging periods,
1 day, 5 and 10 days, for pH, refrigeration losses and colour For the analysed samples were defined two methods of
ageing: wet-ageing (WA) and dry-ageing (DA). Dry-aged samples showed significantly higher refrigeration losses
compared to wet matured samples, losses which increased with the aging time, especially in the case of unpacked meat.
The aging method induced significant differences (p < 0.05) in pH values, with vacuum-packed samples showing higher
pH values compared to dry-matured samples. The highest pH values were noticed for the collar samples, with a
maximum of 6.062±0.038 for the 10-day wet-aged batch. The wet-aged samples were brighter (L*) at all stages of
maturation, but showed higher values for b* (yellowness) after 10 days of maturation. While the dry-aged samples were
significantly redder (higher a*) after 10 days of aging
Nutritional value of new sweet pepper genotypes grown in organic system
No full textThe market request for organic vegetables has grown recently for their positive impact
on healthy diets. Consumers have progressively shown preferences for various combinations of
color, size, and shape of pepper fruits. Facilitating communication, collaboration, and participation
in the selection of cultivars with superior performance, flavor, texture, and culinary attributes can
represent a key tool in breeding for nutritional and culinary traits. The current research started
from the premise that organic production involves achieving adequate nutritional and culinary
quality of pepper fruits. The study was conducted to investigate traits related culinary quality of
pepper genotypes, especially in the ripening phase of fruits, to select the best resources with a high
antioxidant content for breeding programs. The biological material represented by nine genotypes of
sweet pepper was cultivated in the open fields during 2019 and 2020 at the experimental stations
of the Vegetable Research Development Station of Bacau and of Iasi University of Life Sciences.
Agricultural practices and intensive breeding focused on yield and stress tolerance have indirectly led
to a reduction in the nutrition and flavor of the produce. Complex approaches, including screening
of consumer preferences, phenotyping, and use of modern genomics and analytical chemistry tools
in breeding, together with participatory farmer-breeder-chef-consumer collaborations, can represent
a strategy to facilitate the development of the next generation of crops aimed to meet the growing
demands of safe and nutritionally vegetables featured by culinary standards as good flavor, color,
and texture
Territorial organisation of the mountain area in Romania. Regional mountain development centres vs. massive committees
Get PDFThe development of mountain areas is achieved through specific policies. The Law of the Mountain and the subsequent
laws elaborated, aim to support mountain producers, entrepreneurs and implicitly to lead to the development of
mountain areas. In 2019, the Government Decision no. 332/2019 regarding the establishment of the composition, duties
and responsibilities of the massive committee and the National Mountain Council. In order to apply the policies and
strategies for the development and protection of the mountain environment, a massive committee is constituted at
territorial level for each of the 9 mountain groups provided in the annex to the Mountain Law no. 197/2018, body
without legal personality, with advisory role. And, at the national level, the National Council of the Mountain is
constituted, with advisory role, which will ensure the cooperation between the Government and the representatives of
the mountain area, for the implementation of its specific strategies and policies. At mountain territory level, there is a
number of 7 mountain development regional centres and 32 mountain development offices, each of them operated by
one Agency specialist. Each CRDM has a variable number of ODMs subordinated, in its activity range. Every ODM
has a number of settlements assigned to it, for the most part corresponding to two mountain basins. The Regional
Mountain Development Centres are structures of the National Agency for Mountain Areas, and the Mountain
Committees are structures of different organizations, which have a consultative role in supporting public policies

Get PDFThe use of non-Saccharomyces / Saccharomyces cerevisiae starter cultures to reproduce the conditions of natural fermentation in a controlled manner, offers the possibility of improving the aroma profiles of wine and is the basis of strategies for the implementation of new winemaking technologies. In this context, the fermentation potential of the autochthonous strains Torulospora delbrueckii code 10 and Saccharomyces cerevisiae code 4.1.11, 4.3, 4.6 and 4.10 was studied, by inoculation in monoculture, mixed and sequential culture. The obtained results confirm the oenological characteristics of the selected autochthonous yeast strains, as possible basic sources for obtaining new starter cultures
Phenolic and Total Flavonoid Contents and Physicochemical Traits of Romanian Monofloral Honeys
No full textSince ancient times, honey has been appreciated not only for its sensorial traits, but also for the observed effects in rejuvenation and treatment against several bad health conditions, when used externally or internally, along with other beehive products, such as pollen, propolis and royal jelly. Today, it is known that such effects are generated by compounds bearing antimicrobial, anti-inflammatory, and antioxidative features (enzymes, polyphenolic molecules). The purpose of this study was to assess the total phenolic and flavonoid contents of 28 samples of Romanian raw monofloral honey (acacia; linden; rapeseed, sunflower and mint), and to establish their correlations with several qualitative parameters. Pearson’s test revealed a strong positive correlation between total phenolic content and total flavonoids (r = 0.76) and color intensity (r = 0.72). For total flavonoid content, correlations were strongly positive with color intensity (r = 0.81), ash content (r = 0.76) and electrical conductivity (r = 0.73). The relevant levels of polyphenols and flavonoids identified in the analyzed honey types demonstrate its antioxidant potential, with essential nutritional and sanogenic features in human nutrition
Results obtained from sweet cherry breeding in Iaşi, Romania
No full textFrom 1994 - 2016, the
Research Station for Fruit Growing (RSFG)
Iași approved 28 cherry cultivars, of which
three were early cultivars (Cetăţuia, Cătălina
and Amaris), 20 were middle maturation
cultivars (Maria, Golia, Ştefan, Bucium,
Iaşirom, Tereza, Lucia, Radu, Oana, Alexus,
Andreiaş, Ludovan, Cociuvaş, Iosifan,
Paulică, Mihailis, Muşatini, Elaiaşi, Amar
Maxut, and Amar Galata), and five had late
maturation (Andante, Marina, Croma,
Margonia, and George). Van, as the most
widespread cultivar in Romanian orchards,
was used as a control. The sweet cherry
cultivars were created through direct
hybridisation or free pollination. Maria
Cultivar is the first Romanian self-fertile
cultivar. The locally approved bitter cherry
biotypes are Amar Maxut with black fruit,
Amar Galata with double-coloured fruit, and
Amaris with dark red fruit. Regarding the
tree’s vigour, cultivars Amaris, Tereza,
Ştefan, and Golia recorded weak vigour, in
comparison with the other cultivars, which
had medium vigour. Bitter-tasting cherry
cultivars have semi-firm pulp with semiadherence
to the stone, and the fruit weight
was under 7 g. All 28 cultivars presented
high precocity, productivity, fruit quality,
and resistance to frost, drought, and diseases
Researchers on the behavior of sugar beet hybrids in the pedoclimatic conditions of the Central Plateau of Moldova
No full textThe main purpose of the research was to test the productive and qualitative potential of 36 sugar beet hybrids from four
international suppliers. The research was carried out in 2021, in two farms with high-performance plant cultivation
technologies: Agricola 96 from Tiganasi, Iasi county (irrigated regime) and Agri Farm Ltd. from Balanesti, Neamt
county (non-irrigated regime). The maximum biological sugar production in the irrigated system was 11.15 to/ha
(hybrid Fiammeta), and in the non-irrigated system 12.20 to/ha hybrid Borjana). Knowing the productive and
qualitative potential of sugar beet hybrids depending on the local pedoclimatic conditions, is a basic requirement in
choosing the palette of hybrids that will be cultivated in the following years
