RESEARCH ON THE GRAFTING AFFINITY OF VARIETY FOR WHITE WINES ′VRANCEA′ ON ROOTSTOCKS WITH DROUGHT RESISTANCE

Ionica Bosoi — 2024-11-26

Climate changes have considerably influenced the evolution of the thermal and water regime annually and during the growing season in the viticultural ecosystem of the Odobești vineyard. The use of drought-resistant rootstocks for grafting is one of the solutions to counteract this extreme phenomenon, which is increasingly present in the wine-growing areas of southern Moldova. The present paper presents preliminary results regarding the grafting affinity of the ʹVranceaʹ white wine grape variety created at RDSVO Odobești, on three rootstocks with drought tolerance obtained in the Romanian viticultural research (Drăgășani 70). M.′, ′Crăciunel 71 Bl.′, ′Ruggeri 140 Vl.′). The rootstock ′Berlandieri x Riparia Sel.Oppenheim 4 –4 Bl.′, was taken into the study as a control. The obtained results show a good and very good grafting affinity of the Vrancea variety on the ′Ruggeri 140 Vl.′ rootstock

WOODEN MATERIALS USED IN LANDSCAPE APPLICATION IN CRAIOVA CITY

Marius Marius — 2024-11-26

During the history, wood materials have become an indispensable material for human life. (Amati M. 2016). Wood is a material compatible with nature, compatible with other building materials such stone, glasses, offering different texture. (Ahern J. 2007). Wood is one of the materials with best respond to the functions of urban green spaces. First of all, it integrates best, from an aesthetic point of view, alongside stone in urban landscaping projects. (Aybike Ayfer KARADAĞ et al. 2017).Since wood is a natural product, its dimension is limited in that its fibrous structural capacity to bear weight varies according to the fiber direction. Despite its widespread use, it had not been used in multi-storey and wide-span structures to the extent of reinforced concrete and steel structures commonly built after the industrial revolution. (Daniel K, Ternaux E. Materiology. 2009)

THE BODY'S RESPONSE TO STRESS

Mariana Luminiţa Olaru — 2024-11-26

Stress, an undeniable reality of everyday life, is a natural reaction of the body to any pressure, threat or demand that requires an intense physical or mental response. It has a positive aspect, "good stress", which can provide additional motivation to complete tasks or face challenges. On the other hand, there is also a negative aspect, excessive stress affecting physical, mental and emotional health. In my opinion, in order to be able to cope with stress, it is important to manage changes, accept failures, put our own needs first, communicate clearly and effectively, eliminate negative thoughts and take emotional risks. Deep understanding and developing stress management skills can significantly contribute to improving the quality of life of each individual

FIRST IDENTIFICATION OF DOWNY MILDEW ON QUINOA (PERONOSPORA FARINOSA F. SP. CHENOPODII) IN ROMANIA: PRELIMINARY RESEARCH

Cristinel Relu Zală — 2024-11-26

With the expansion of quinoa cultivation (Chenopodium quinoa Willd.) into new areas, including Romania, it is expected that specific diseases will emerge. Currently, downy mildew is the most significant and studied disease affecting quinoa worldwide. This research was conducted in the experimental fields of the UASVM of Bucharest, under the climatic conditions of the 2024 growing season. Two quinoa varieties, supplied by Quinoa Quality ApS, Denmark, were evaluated for their response to the pathogen Peronospora farinosa f. sp. chenopodii. The first detection of downy mildew in quinoa in our country provides an important update to phytopathological research on this crop, which offers numerous economic advantages in the current climate context. The characteristic symptoms of the disease caused by the pathogen Peronospora farinosa f. sp. chenopodii are described. Vikinga was susceptible to downy mildew (AD 6.6%), while Puno showed an insignificant degree of leaf infection (AD 0.65%).

RESEARCH ON CAPITALIZING ECOLOGICAL CONDITIONS SPECIFIC TO THE PERIURBAN AREA OF THE CITY OF CRAIOVA THROUGH CULTIVATION GRAPES FOR OBTAINING D.O.C. WINES "BANU MĂRĂCINE"

Dorin Constantin Costea — 2024-11-26

The peri-urban area is located on the border between the urban and the rural environment, it has distinct characteristics that reflect the influences of both types of spaces. The Banu Mărăcine wine area is recognized as part of the wine areas with the widest vocation for obtaining wines with the right to carry the designation of controlled origin (D.O.C). Starting from these considerations, vine growers and especially the specialists from the Banu Mărăcine S.D., try to identify possibilities to maintain at a high and constant qualitative level the specific character of wine production, taking into account the climatic changes that have occurred in the last years. The present paper represents a case study regarding the results of grapevine cultivation in the Banu Mărăcine wine area, located in the peri-urban area of the city of Craiova.

QUANTITATIVE ANALYSIS OF NUTRITIONAL AND BIOACTIVE COMPOUNDS IN FRUITS OF KIWANO (CUCUMIS METULIFERUS E. MEY) TEMPUS CULTIVAR

Simona-Mariana Micu — 2024-11-26

Locally-grown kiwano fruits, Tempus cultivar, were evaluated for their content in some main classes of nutritional organic compounds. With 448/98 mg/kg DW (pulp/peel) total carotenoid content was average when compared to other Cucurbitaceae. Among identifiable carotenoids, lycopene was the only one in notable amounts, in peel (12% of total carotenoids). With 51,751/37,624 mg/kg, total phenolic inventory was extremely rich. Flavonoids were clearly dominant (78/49%). Hydroxycinnamic acids were found in significant proportions (11/27%). Fruit pulp also showed some amounts of tannins (5.9%) and stilbenes (2%), while coumarins were found in low amounts. Ascorbic acid was abundant, 20,140 mg/kg in pulp and 7,689 mg/kg in peel. Soluble sugars were 15,915 /6,634 mg/kg while lipids were 5,556 /2,721 mg/kg.

ASPECTS CONCERNING RESULTS OBTAINED THROUGH IMPROVEMENT ACTIVITIES PERFORMED UPON SOME AUTOCHTHONOUS AND FOREIGN VINE KINDS

Aurel Popa — 2024-11-26

The present work does illustrate through some rather detailed examples the creation process throughout Romania of some new (and most useful in current culture) vine kinds. The materials made use of in this taken action have consisted in both indigenous and foreign (imported after the phylloxera’s disaster) kinds. The chosen genitors as well as the surfaces nowadays cultivated with those newly created vine kinds are therefore enumerated in their details. Recommendations are suggested in view of ensuring their best ever respective performances.

STUDY OF THE POLYPHENOLIC POTENTIAL OF RED WINE GRAPE VARIETIES CULTIVATED IN DIFFERENT VINEYARD AREAS IN OLTENIA

Felicia Stoica — 2024-11-26

The basic idea that governs the tracking of the ripening of grapes, in order to determine the time of harvest, is that the grapes harvested at the best time, considered optimal, allow the extraction of the maximum quality from the constituents of the grains (in our case, the maximum of phenolic compounds).
The degree of ripening of the grapes largely determines the must yield during primary vinification, but especially the composition and quality of the resulting wine. A premature harvest leads to a decrease in the must yield, while a delay results in harvest losses and a decrease in the total acidity of the must, both inconvenient situations leading to a decrease in the content of polyphenols.
All these considerations converge towards the final goal, namely, to capitalize as effectively as possible on the oenological potential of the varieties, for the production of quality red wines, polyphenolic and sensorial balanced.

OBSERVATIONS ON THE COLEOPTERAN FAUNA IN THE FOREST ECOSYSTEM LOCATED IN THE NECHIT AREA, NEAMȚ COUNTY

Marius Vasile Bârdan — 2024-11-26

In this study, the research material is represented by coleopteran species found in a mixed forest In this study, the research material is represented by beetle species found in a mixed forest composed of deciduous and coniferous tree species, covering an area of 8 hectares. The forest is located in an area with rich biodiversity, characterized by a natural succession of tree species and a varied pitfall, which is conducive to the development of diverse fauna.
This paper focuses on analyzing the structure, dynamics, abundance, and ecological role of beetles within this forest ecosystem, emphasizing their interactions with other species and the abiotic environment. The collection of fauna was carried out using pitfall traps type Barber, which are ecological traps, during the year 2024, from July to September, over a period of three months. A total of 6 traps were installed at various marked locations in the forest, depending on vegetation density, to adequately cover habitat diversity. The material from the traps was collected at regular intervals of 10-14 days to monitor the activity of beetle species. Throughout the study, 6 collections of entomological material were conducted on the following dates: July 10, July 22, July 31, August 14, August 28, and September 11. Among the most frequently collected species are Poecilus cupreus, Necrophorus vespillo, Geotrupes vernalis, Aptinus bombarda, and Silpha carinata. These species have a significant ecological impact on the ecosystem, playing key roles in organic matter decomposition and nutrient recycling, pollination processes, and controlling populations of harmful insects. Additionally, some of these species may be classified as harmful fauna in certain contexts, having the potential to affect the natural balance of other insect species or even the vegetation. However, overall, the majority of the beetle species collected in this study have a beneficial role and are essential for maintaining the health of the analyzed forest ecosystem.

FARM TO FORK STRATEGY: A SUSTAINABLE SOLUTION FOR RURAL COMMUNITIES

Apostolos Goulas — 2024-11-26

The Farm to Fork (F2F) strategy, a key pillar of the European Green Deal, offers a comprehensive and sustainable solution for food systems, with particular benefits for rural communities. This strategy emphasizes the transformation of food production, processing, distribution, and consumption to achieve environmental sustainability, economic resilience, and food security. As rural communities often face unique challenges—such as limited access to markets, declining populations, and environmental degradation—the F2F strategy provides an integrated approach to addressing these issues. By promoting shorter supply chains, organic farming, reduced pesticide use, and climate-resilient agricultural practices, the F2F strategy can enhance rural livelihoods while contributing to global climate and health goals. This paper examines the economic, environmental, and social impacts of the F2F strategy on rural communities, and highlights the challenges and opportunities associated with its implementation. It argues that, while the strategy holds great promise for promoting sustainable rural development, its success depends on adequate financial support, infrastructure investments, and education for farmers and stakeholders.

Eduard Marius Negulici Eduard Marius — 2024-11-26

Since the beginning of time, flowers have been a way to celebrate all the major events in our life. Roses breeders captured moments in history from famous painters like ‘Paul Gauguin’ or great personalities such as ‘Queen Elizabeth’, to melodies that we are remembering since the first time we heard them, like Gershwin’s ‘Rhapsody in Blue’. In this paper we will try to highlight some floribunda roses that are famous by their name and the importance they represent for the collections of roses.

PHOTOSYNTHESIS ACTIVITIES OF MELON CULTIVARS UNDER FLOODING ENVIRONMENT

Seymen Musa Seymen — 2024-11-26

Flooding is such a stress factor leading to reduction in both the yield and quality of crops. One practical solution lowering yield and quality performances of crops in areas with flooding risks is to practice of tolerant plant cultivars. The major purpose of the present work was to identify the most suitable cultivars within 11 different Kırkağaç melon cultivars in accordance of photosynthesis activities. In such pot experiment, all treatments were irrigated with same amount of water during stages of seed sowing-initial of stress applications, and 10-day stress was applied to treatments having the flooding stress in time with plants having four-five leaves. In plants, harvested just after stress application, leaf temperature, stomata conductivity, quantum yield of photosynthesis, and photochemical yield of photosystem II were examined. In results, flooding stress had no significant effects on leaf temperature and stomata conductance but resulted important reductions in quantum yield of photosynthesis, and photochemical yield of photosystem II. There were observed changes among cultivars, and Sürmeli F1 (V-5), Kırkağaç local cultivar (V-10) and Kyrgyzstan local cultivar (V-11) performed maximum photosynthesis activity.

Ovidiu Țucă — 2024-11-26

Invasive plants, introduced either accidentally or intentionally to new ecosystems, can outcompete native vegetation, alter habitat structures, and influence the food web. Native insects, which often have co-evolved with indigenous plants, are particularly vulnerable to such changes. This paper explores the complex relationship between invasive plant species and native insect populations, focusing on habitat loss, food availability, and the cascading ecological consequences that result from such interactions.

EFFECTS OF HYPOTHERMIC STRESS APPLIED TO SEEDS BEFORE GERMINATION ON THE PARAMETERS OF THE PHOTOSYNTHETIC APPARATUS OF MAIZE PLANTS

Maria Cauș — 2024-11-26

In maize (Zea mays L.) plants grown from seeds pre-treated with negative temperature stress (NTS) of -4°C for 16 hours before germination, followed by growth in dark and light conditions, the content of chlorophyll pigments (Chl) in leaves, the chlorophyll content index (CCI) and some gas exchange parameters were assessed. Combined application of NTS and illumination conditions to seedling growth showed that 6-day-old NTS maize seedlings grown in the dark were etiolated, contained carotenoids and traces of Chl a and Chl b. Whereas in green seedlings grown in the light, NTS decreased Chl a, Chl b and carotenoids. NTS also reduced the CCI in1st, 2nd and 3ed leaves of plants grown in the light for 17 days. While in the 1st, 2nd and 3ed leaves of control plants that grew in the light, the CCI changed dynamically, showing a maximum on the 9th day of growth and then decreased. The influence of NTS also affected the parameters of gas exchange in leaves, causing a decrease in CO2 exchange, real CO2 absorption and total respiration.

SUCCULENT PLANTS IN CONTEMPORARY FLORAL DESIGN

Manuela Manda — 2024-11-26

Succulent plants are cultivated for decorative purposes, for interior decoration, in landscape design projects, potted arrangements (container gardens), and, in recent years, as "cut flowers". Succulents feature robust leaves, bright colors, unique textures, and shapes, offering a distinct appearance compared to other flowers. When placed in a vase or arranged in floral designs, succulents add an air of elegance, often serving as focal point due to the striking look of their rosettes. Their unique aesthetic makes them stand out in any arrangement, bringing a modern and refined touch to floral art. In the present work, we aimed, in addition to documenting the range and potential uses, to identify species of succulents that are suitable for use in floral design and to create floral compositions using succulent plants or in combination with other species.

The traps were placed in two rows at a distance of 6-8 m per row and 8-10 m between rows. The traps operated from June to September in 2024. Periodic collections of the collected material were made at intervals of about 14 days. At each collection, the NaCl solution was replaced with a concentration of 25g/l, and each sample was labeled specifying the date of collection and the number of the trap. The samples thus collected were brought to the laboratory where they were cleaned of plant remains and the epigean entomofauna was selected, as well as species of crustaceans, myriapods and arachnids. The determination of the species was done with the help of the determinants and the images on the specialized websites. The most frequently collected insect species were: Poecilus cupreus, Amara spp., Pseudophonus pubescens.

QUANTITATIVE ANALYSIS OF NUTRITIONAL COMPOUNDS IN IRRIGATED AND NON-IRRIGATED LINSEED (LINUM USITATISSIMUM L.) CULTIVAR ALEXIN

Simion Enuță — 2024-11-26

Flax from cultivar Alexin was grown on three different water regimes: non-irrigated, half-dose and full-dose irrigated. Seeds were harvested and taken for biochemical analyses.
They were found to contain low amounts of carotenoids, 7.57-12.79 mg/kg, with notable amounts of lycopene, lutein and zeaxanthin, but no detectable β-carotene. Phenolic inventory was also low, but consistent with values usually found in ungerminated linseed: 3,106-7,211 mg/kg, dominated by flavonoids (37-51%; of which minor amounts of flavanols and anthocyanins) and hydroxycinnamic acids (23-37%). Coumarins and stilbenes had low concentrations.
Oil content ranged from 21.3% in non-irrigated plants to over 29% in fully irrigated ones. Ascorbic acid content showed little variation, with 985-1,187 mg/kg, while soluble sugars were 2,482-4,073 mg/kg.
The concentrations of all these compounds, except for cryptoxanthin, were positively correlated to water dosage. The most affected by irrigation regime were phenolic compounds and sugars. The least influenced was ascorbic acid.

ANATOMICAL CHARACTERIZATION OF STACHYS MARITIMA GOUAN VEGETATIVE ORGANS

Dan Răzvan Popoviciu — 2024-11-26

Stachys maritima Gouan is a perennial herbaceous plant from the Lamiaceae family. It only grows on sand dunes, especially littoral ones. In Romania it is considered an endangered species, only found in few coastal areas of Tulcea and Constanța counties. Its vegetative organs (rhizome, aerial stem, leaf petiole and leaf blade) were harvested for anatomic analysis.
The rhizome showed a secondary structure, with thin suber, compact and thin phloem and compact xylem annual growth rings, while pith was mostly replaced by xylem elements. Aerial stems had the four-ridged shape common in many Lamiaceae, with caps of angular collenchyma protecting four major, semicircular, collateral vascular bundles. Multiple secondary bundles were also found, joined together by sclerified external pith layers. Leaf petiole was filled with undifferentiated parenchyma, made up of large polygonal cells, similar in shape to stem cortex and pith. Leaf blade had a weakly differentiated bifacial structure and was amphistomatic. Stems and leaves were covered by dense, massive, lignified tector hairs. Secretory hairs were small, exclusively peltate, mostly found on stems.

Felicia Tuțulescu — 2024-11-26

International competition in the wine sector and the demands of discerning consumers for unique wine styles are challenges with implications for the fermentation process. The basis of quality alcoholic fermentation involves knowing how yeast strains interact with the aroma, taste, consistency and color of the wine. Perfect grape health is essential for producing a wine with outstanding organoleptic qualities, but it is not enough. This study investigates the effect of pesticides applied in viticulture on yeasts present in the epiphytic microflora of grapes.

THE INFLUENCE OF EXTREME TEMPERATURES ON THE PHYSIOLOGY OF SOME WOODY SPECIES FROM THE SOUTHWEST AREA OF ROMANIA

Luminita Buse-Dragomir — 2024-11-26

The temperature differences recorded in recent years have allowed studies to be carried out to explain how plants react to climate change. Both cultivated and wild plants are affected.
In the present study, the physiological parameters of 4 woody species that grow spontaneously in the south-western area of Romania were determined: Juglans regia, Populus nigra, Morus alba and Tilia platyphyllos.
The determinations indicated significant differences in the phenology of these species but also in terms of the intensity with which some vital processes are carried out.
It is obvious that the studies presented cannot be generalized, but they constitute a first step in establishing the influence exerted by extreme temperatures on the analyzed plant species.

STONE UTILISATIONS IN LANDSCAPE APPLICATION IN CRAIOVA CITY

Marius Gruia — 2024-11-26

In many ways stones are the bone of the earth. Stone in its many forms is a tangible, useful material that can find a place in every yard. The color selection, texture, cuts and paver size available will cater to any project for landscape. (Kristen Hampshire et al. 2009).
In the beginning, the gardens had a utilitarian purpose, being made up of plants with a food role. Then the gardens take on the role of religious meditation, rest, culture and recreation. (Daniela Posta. 2015).
Stone is a material that is born and evolves in nature as it is detached over time with stable, simple and almost primitive methods. Therefore, together with wood, it is undoubtedly the most suitable material for the formation of forest recreation areas, which are the most widespread means of human contact with nature and its beauties. The use of stone constructions in forest recreation is perfectly in harmony with the natural environment. Thus, people have the possibility to escape from the hectic rhythms of everyday life in forest recreation areas, relax and enjoy the forest through the conveniences offered by the stone constructions. (Vasileios C at al. 2023)

ULTRASOUND APPEARANCE OF THE ENDOMETRIUM AND CLINICAL CORRELATION IN A CASE OF AMENORRHEA

Olimid Diana Olimid — 2024-11-26

The subject of this paper is the presentation of a clinical case of amenorrhea in a young woman with regular menstrual cycles and a positive pregnancy test. The ultrasound examination of the uterus at 5 weeks and 1 day after the last menstruation showed the absence of a gestational sac and a thin and hypoechoic endometrium. Since the pregnancy test was positive, the ultrasound examination was repeated after 7 days. During this interval, the patient presented a hemorrhage. The ultrasound performed 4 days after showed a thin endometrium with medium echogenicity. Repeating at 48 hours the measurement of the human chorionic gonadotrophin hormone showed low values that decreased, which correlated with the clinical and ultrasound aspects confirmed the diagnosis of early pregnancy failure.

DEVELOPMENT OF VEGETATION PHENOPHASES IN SOME PLUM CULTIVARS GROWN IN THE CRAIOVA AREA

Valeriu Zanfir — 2024-11-26

The paper studied the development of the vegetation phenophases in three plum cultivars (ˈAndreeaˈ, ˈRecordˈ and ‘Čačanská lepotica’), analyzing how climatic variations and environmental factors affect their development. The BBCH scale was used to record the different phenophases. The number of days from November 1 to budding, the duration of budding, the duration of the flowering period, the number of days from the appearance of the fruits to the ripeness for consumption were calculated and it was found that the phenological stages occurred without too great differences from one cultivar to another. This is due, on the one hand, to the fact that the three cultivars were grafted on the same rootstock, and on the other hand, to the close fruit ripening period.

ANTIOXIDANT ACTIVITY IN EXTRACTS FROM VARIOUS ORGANS BITTER GOURD (MOMORDICA CHARANTIA L.)

Simona-Mariana Micu — 2024-11-26

Bitter gourd (Brâncuși cultivar) stems, tendrils and leaves from plants locally grown at the „Ovidius” University, Constanța, were extracted in 70% ethanol solution and analyzed for antioxidant activity.
The highest antioxidant activity was found in tendrils (53.08%), flowers (51.53%) and fruit pulp (49.64%). Lowest values of IC50 were found in flower (34.46 mg/L) and fruit pulp (39.47 mg/L) extracts. These values are high when compared to other known Cucurbitaceae, especially in regard to vegetative organs. Considering the known contents of bioactive compounds in M. Charantia organs, the antioxidant activity cannot be directly correlated to total phenolic concentrations, those of flavonoids or ascorbic acid.

Petronela Camen-Comănescu — 2024-11-26

Urban parks are essential for maintaining biodiversity in cities. This study assesses the tree diversity and ecological resilience, and stress tolerance of species in five major parks in Bucharest: Herăstrău, Kiseleff, Tineretului, Cişmigiu, and Carol. A total of 125 species from 32 families were recorded, with the highest diversity in Cişmigiu and Carol and the lowest in Kiseleff. NMDS analysis revealed similar species compositions in all parks except Kiseleff, which was distinct. No significant correlations were found between species richness and park size or age, suggesting other factors, such as management, play a larger role. Species with higher tolerance to drought and air pollution are significantly more present in Bucharest’s parks, while pest tolerance shows no significant difference in their presence. The predominance of non-native species, particularly invasive ones in Cişmigiu and Tineretului, underscores the need for better management. ANOVA results confirmed significant differences in the distribution of non-native species categories, emphasizing the importance of targeted strategies to control invasive species and promote native biodiversity.

As results of the investigations we found that: the highest vigour was obtained at ‘Aura’ (45.50 mm) and ‘Rubinola’ (42.83 mm) cultivars in 3rd fertilization variant (Biohumus – 0,9 l/tree, soil application + Algacifo 3000 – 3 l/ha, foliar application); the best results regarding the fruits yield were also obtained in the 3rd fertilization variant (Biohumus – 0,9 l/tree, soil application + Algacifo 3000 – 3 l/ha, foliar application), among the cultivars being noted the ‘Luna’ cv. with an average fruit yield of 20.18 kg/tree and ‘Rebra’ cv. with 18.49 kg/tree.

THE IMPACT OF THE FOLIAR FERTILIZATION ON THE SWEET CHERRY TREE PRODUCTIVITY

Valerian Bălan — 2024-11-26

This study aims to determine the impact of the nanotechnology-based foliar Pistachio Mix Plus NPA fertilizer on the yield and quality of sweet cherries. The research has been conducted using the 'Kordia' sweet cherry variety grafted on the Gisela 6 rootstock and planted at a distance of 4x1 m. Between 2023 and 2024, the foliar fertilizer was used during four phenophases of flower bud development in a dose of 2.5 l/ha. The fruit yield increased by 14.9-30.1%, when the Pistachio Mix Plus NPA was used 2.5 l/ha three times, in comparison with the yield of the sweet cherry trees which were not treated with the fertiliser. The foliar fertilization with microelements has increased the number of fruits with a diameter larger than 30 mm by 64.6-65.4%. Thus, the fruit yield and quality can be improved in sweet cherry orchards using nanotechnology-based foliar fertilizers during three fruiting phenophases, namely pink-white bud + petal shedding + the beginning of ripening.

Aurelian Valentin Untaru — 2024-11-26

The walnut crop has a long tradition on the territory of Romania. One of the problems of walnut crop is tree size (about 25-30 m high), which makes difficult some technological practices (pruning, spraying and harvesting). The low vigour of the trees is not the most important objective in walnut breeding program, but it is necessary to find the genitors with this trait. The goal of this paper, is to evaluate the trees vigour of 32 Romanian walnut genotypes, from germplasm fund of RIFG Pitesti, Romania in order to identify the most valuable genotypes that will be recommended for spread in commercial orchards or use as genitors in breeding works. The results obtained have highlighted the fact that in walnut collection from RIFG Pitesti there is a large phenotypic diversity. The genotypes 'Sibișel 252', 'Claudia Ioana', 'Ciprian Ion', 'Geoagiu 265', 'Germisara', 'Jupânești', 'M 44-39', 'Orăștie', 'Roxana', 'Sarmis', 'Sibișel 44' were noted with low vigour. Also, 'Dacus' - generative rootstock has had a low vigour and can be recommended for grafting of walnut cultivars intended for intensive orchards.

Marian-Florin Gavrilă — 2024-11-26

The researches performed at Voineşti Research and Development Station for Fruit Growing in the apple breeding program for obtaining varieties with resistance to diseases highlights the biological characteristics of some existing genotypes in the competition microculture established in 2019. In the 11 apple genotypes taken in the study, compared to the 'Florina' variety taken as a reference, it is analysed the evolution of the flowering phenophases, the period of fruit ripening and storage, as well as the quality determined by biomass, dry matter content and firmness of the pulp during 2022-2024. Some of the apple genotypes in the competition microculture meet the requirements imposed for the approval of new varieties with resistance to diseases, which can meet the market requirements and the expansion in modern orchards from the established orchards. From the recording of the flowering phenophases, it is noted that they are advanced by about two weeks in the year 2024, compared to the years 2022 - 2023, due to the increase in temperatures in March, against a background of sufficient moisture, being a signal for the study of phenology in the face of climate change. The apple genotypes with disease resistance present fruits intended for fresh consumption, most with winter ripening, with a compact, consistent firmness and an appreciable dry matter content, characteristics that promote them for the approval of new varieties. Three of the apple genotypes were registered for homologation, one becoming the 'George' variety, being appropriate to the demands of the producer, sensitive to economic efficiency, with quality fruits, which will certainly meet the ever-increasing consumer demands.

MORPHOLOGICAL CHARACTERS IN PROGRESS FOR FIELD PEAS (Pisum sativum L.)

Nicolaie Ionescu — 2024-11-26

Since ancient times, the field pea has stood out, on the one hand, for its special nutritional value, and, on the other hand, for the favorable impact it leaves on the environment through cultivation. Currently, more and more performing varieties are obtained and with increased adaptability in different environmental conditions. Recently, the plant is also recommended for the establishment of green, protective crops, including in horticulture. It is believed that by growing peas, there is also a conservation of CO2, as a response to the need to reduce the phenomenon of global warming. The new pea variety Avatar thus has a number of improved morphological characters, which proves that pea breeding is making visible progress. Among these new morphological characters, the height of the plant was 80 cm, with the dominant weight of 11 g. The plant had 15 nodes of which the last 6 formed pods. Pod mass was 8 g/plant and contained 22 grains/plant. Pea grains had a mass of 5 g/plant, a diameter of 7 mm, and an absolute mass (BMB) of 260 g. The correlations obtained between these characters showed generally positive trends. Considering the gain of these morphological characters in progress, it is recommended to increase the proportion of the plant in the structure of crops within the farm.

Enuță Simion — 2024-11-26

Safflower cultivar CW 4440 was grown on two different water regimes: non-irrigated, and full-dose irrigated. Achenes were harvested and taken for biochemical analyses.
They were found to contain low amounts of carotenoids, 2.38-4.38 mg/kg, with notable amounts of lutein and minor concentrations of xanthins. All carotenoids, except for cryptoxanthin, reached their highest values in irrigated plants, while β-carotene was found in detectable amounts only in irrigated plants. Phenolic inventory, on the other hands, was high compared to known data in literature: 40,627-44,574 mg/kg. Of these, hydroxycinnamic acids were dominant, with 26,023-28,233 mg/kg (63-64%). Flavonoids reached 11,854-13,201 mg/kg (29-30%), including a major fraction of flavanols (1,469-1,595 mg/kg). Stilbenes were another major component, with 2,516-2,750 mg/kg. All the highest values were found in irrigated plants.
Oil content ranged from 6.1% in non-irrigated plants to over 11.7% in irrigated ones. Ascorbic acid content was low (349-756 mg/kg), while soluble sugars were 1,731-2,508 mg/kg.
The concentrations of all these compounds, except for cryptoxanthin, were positively correlated to water dosage. The most affected by irrigation regime were carotenoids, ascorbic acids and oil. The least influenced were phenolic compounds.

George Lucian Badea — 2024-11-26

With the exception of the high areas of the Oltenia mountains, vines are cultivated in all localities, from the Danube to the Parâng mountains, from the charming Porti de Fier to the legendary Olt river. It is cultivated on small and scattered areas in all the provincial villages, but it is not absent from the eaves of the houses, bringing them a unique architectural charm in the country. The wine plantations concentrated in the vineyards and wine centers are the ones that ensure the production of good quality grapes from which the famous red, white and aromatic wines of superior quality are obtained. The vineyards and wine centers of Oltenia are geographically located in the five counties (Mehedinți, Gorj, Dolj, Olt and Vâlcea) where, under the influence of different environmental conditions, they offer the chance to obtain practically all types and categories of wine.

Sevastița Ariciu — 2024-11-26

The Fetească Neagră variety is a native vine variety that is part of the varieties for high quality red wines, with high growth power, increased resistance to frost and drought, but sensitive to manna and powdery mildew. This paper presents aspects related to vegetative propagation by cuttings in this grape variety, using several rooting substrates without applying rooting stimulants. The cuttings were harvested from the plantation at the Banu Mărăcine Research Station, and the experiments were placed in the Greenhouse Complex of the "Alexandru Buia" Botanical Garden of the University of Craiova. The following variants were used for rooting the cuttings: water (control), peat (V1), peat + perlite 2:1 (V2), sand (V3), mold leaf (V4). Sprouts and leaf formation recorded the highest values in the control variant (water), followed by variant V4 (mold leaf) and variant V3 (sand).

HOW CLIMATE CHANGE AFFECTS COTTON AND WHEAT CROPS IN GREECE THE LAST FIFTEEN YEARS

Rafael-Ioannis Antonopoulos — 2024-11-26

This paper presents the undoubted change of the Earth’s temperature since the past three centuries (18th, 19th and 20th respectively). Climate change and its impact on agriculture and water resources have become a global concern, however, despite that, how does climate change effect common crops, like cotton and wheat?
By utilizing and comparing the data of the temperature of the year 1978 and the latest year of the database (2022), the average temperatures are 15,15 °C (59,27 °F) and 16,75 °C (62,15 °F) respectively. The precipitation rate has not been reduced. Although the changes in precipitation are not stable due to specific factors, the increase of the temperature tends to cause increase crop evapotranspiration (ETc) which eventually leads to more precipitation. Since the temperature has been increased, the duration of each growing season is shorter, due to the fact that the desired temperature has been achieved earlier. Increased temperature has an immediate effect on the increase of ETc and therefore at the crop coefficient factor.

RESULTS REGARDING THE INFLUENCE OF GREEN MANURE USAGE ON MAIZE CROP ON ACIDIC SOILS IN THE NORTHWEST OF THE COUNTRY

Peter-Balázs Ács — 2024-11-26

This paper presents the efficacy of green manures in raising soil fertility and enhancing crop productivity, on the Albic Luvisols in northwestern Romania.Green manures are cover crops that provide various benefits when added to the soil. Peas are especially effective at increasing organic nitrogen in the soil, leaving behind a significant amount of 471.74 kg N(a.s.) per hectare. Regardless of the pressure from the pathogen Fusarium spp. and the pest Ostrinia n. the maize yield was not affected. The incorporated green manures especially peas, significantly raises maize yield surpassing the control with almost 3000 kg. The quality of the maize crop, specifically starch content and hectoliter weight, was not influenced by either green manure or chemical fertilization.
