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

2024-11-21T06:15:42+00:00

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

2024-11-23T06:45:58+00:00

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.

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

2024-11-24T06:11:58+00:00

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

2024-11-24T09:10:31+00:00

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.

ANALYSIS OF THE DIVERSITY OF SOME HOT PEPPER (CAPSICUM ANNUUM L.) POPULATIONS FROM SOUTHWEST ROMANIA ON THE BASE OF MORPHOLOGICAL AND PRODUCTION CHARACTERS

2024-11-21T22:22:22+00:00

This study presents the characterization of 10 local hot pepper populations selected from the existing germplasm collection within the vegetable growing laboratory of the Faculty of Horticulture in Craiova regarding morphological and productivity characters. Variability analysis indicated low to high variability for most of the characters studied. The average values ranged between 5.3 cm and 10.1 cm for fruit length, between 1.12 cm and 9.38 cm for fruit diameter, between 1.96 cm and 2.86 cm for peduncle length, and for the index of shape values were between 0.69 and 7.58, indicating a conical-elongate fruit shape in most populations. Regarding the number of fruits per plant, there was a very large variation, from 9.1 fruits/plant at V1 De Mârsani to 107 fruits/plant, and the weight of the fruit was between 2.8 g and 11.1. g, and fruit production/ha varied from 3.5 t and 21.0 t/ha. The differences between the studied populations suggest that they can be used in breeding programs for this species.

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

2024-11-24T05:17:28+00:00

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.

TREE DIVERSITY AND RESILIENCE IN BUCHAREST URBAN PARKS

2024-11-21T09:54:31+00:00

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.

2024-11-24T08:06:29+00:00

Research was carried out in an apple field trial established in 2022 at Genetic and Breeding Department of RIFG Pitești-Mărăcineni, Romania. The following determinations were carried out: trees vigour (trunck diameter – mm; crown dimensions – cm; number and lenght of the annual shoots – cm) and yield (kg/tree). 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

2024-11-20T16:13:03+00:00

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.

2024-11-24T05:55:03+00:00

The aim of this study is to study the variability of apparent electrical conductivity, quantity, and quality characteristics in a chestnut farm. The experiment took place in a chestnut orchard located in Agia, Larissa, Greece during the 2022 – 2023 growing season (April 2023 – October 2023), and specifically from the stage of tree dormancy to the stage of harvesting. All cultivation treatments were performed uniformly according to the farmer’s protocols. Soil data and chestnut samples were taken and evaluated to measure the above-mentioned variables (apparent electrical conductivity, quantity, and quality characteristics). The results showed that there was no significant correlation between apparent electrical conductivity and chestnut quality or quantity. They also showed obvious correlation between quantity and quality of chestnuts (high mass means plenty of chestnuts and vice versa).

EVALUATION OF THE PRE (PLANT RISK EVALUATION) INSTRUMENT IN THE SCREENING OF ORNAMENTAL PLANT SPECIES FROM ROMANIA USED IN URBAN LANDSCAPING

2024-11-24T07:17:21+00:00

The aim of our study is to test the applicability of the PRE (Plant Risk Evaluation) tool under the conditions of the temperate continental climate in Romania. This tool can provide a promising basis for the evaluation of ornamental plants used in urban landscaping in Romania. For testing, we used 10 alien species of ornamental plants declared invasive in Romania and 10 alien non-invasive ornamental species. For each species, we created an evaluation sheet that includes the questions, answers, score, degree of confidence and bibliographic list. The final score obtained using the PRE varied between 20-22 points for invasive plants, indicating a high risk of invasiveness and between 3-9 points for non-invasive plants, indicating a low degree of invasiveness.

EVALUATION OF THE TREE VIGOUR AND ANNUAL GROWTH OF SOME ROMANIAN WALNUT GENOTYPES FROM RIFG PITESTI COLLECTION

2024-11-24T08:48:15+00:00

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.

IMPLEMENTATION OF THE HACCP SYSTEM FOR THE PRODUCT BREAD WITH POTATOES

2024-11-21T09:40:37+00:00

Bread is a product that has undergone a wide range of changes depending on the region, people, or culture and has become a symbol in certain parts of the world. In recent times the taste of the bread buyer has been modernized, with different secondary raw materials (seeds, potatoes, olives, onions, etc) being introduced into the dough.
Implementing the quality manual in a company whose main activity is bakery for the production of the product bread with potatoes consisted of going through the stages of the HACCP system, in strict compliance with the principles of HACCP. The main points were: checking the documentary system, establishing the work team, describing the product and distribution methods, describing the raw and secondary materials, constructing the technological flow diagram, determining the critical control points, and validating the HACCP plan.

PRELIMINARY STUDIES ON THE INFLUENCE OF THE CLIMATE ON THE PHENOLOGY OF THE VARIETIES FOR BLACK GRAPEVINES GROWN IN THE BANU MĂRĂCINE VITICULTURAL CENTER

2024-11-23T07:09:54+00:00

Each wine-growing area is characterized by the presence of a complex of climatic, edaphic and anthropogenic factors, which can influence the moment of the onset of the phenophases, the duration of the phenophases, the quality and quantity of grape production, depending on the genetic characteristics of the varieties, the specific climatic conditions of the crop year and by the applied technology. Starting from these considerations, the present work represents a preliminary stage of a case study regarding the observation of how 3 grape varieties: Cabernet Sauvignon, Merlot and Fetească neagra go through the main phenophases in the climatic conditions specific to the Banu Maracine wine center in the year 2023, as well as the evaluation of the productive results obtained. The study proves to be important in the context of the changes found in the course of the phenophases as a result of the climate changes that have occurred in recent years.

THE STUDY OF THE ADAPTABILITY OF TWO CHOKEBERRY VARIETIES IN THE DOBROGEAN AREA – PARTIAL RESULTS

2024-11-24T06:25:51+00:00

The cultivation of fruit bushes in Romania has recently grown exponentially, which has led to the diversification of cultivated shrub species. If in the first part of this interest for shrubs sea buckthorn was by far the winner with the establishment of more than 3,000 ha nationally, followed by the blueberry crop with another 2,000 ha, aronia has become a crop that shows increased interest from farmers. At present, chokeberry cultivation amounts to over 500 ha at the national level. In the official catalog of varieties from Romania, we find a variety registered ”Melrom” maintainer being ICDP Pitesti, and in private nurseries we also find the variety ”Nero”, a variety brought to Romania for testing and acclimatization. In this paper, we observed the two varieties ”Melrom” and ”Nero”, varieties planted in the fall of 2023 in the experimental fields of SCDP Constanța.

THE STUDY OF SOME APPLE GENOTYPES WITH RESISTANCE TO DISEASES CANDIDATE FOR OBTAINING NEW VARIETIES

2024-11-21T22:44:17+00:00

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.

The research conducted at Livada ARDS in the 2023-2024 agricultural year aims to identify new plant species with high yield, quality, and adaptability to acidic soils. By cultivating and expanding these species, we can select those with the widest ecological plasticity for use in green crops (cover crops), animal feed, human food, and biomass production. This cannot be done without modern agricultural machines and drones.

CONSIDERATIONS REGARDING THE VASCULAR FLORA OF THE PROTECTED AREA PREAJBA-FACĂI LACUSTRINE COMPLEX, DOLJ, ROMANIA

2024-11-24T07:06:12+00:00

The objective of the present research was to identify all vascular species of aquatic and marsh plants within the protected area Preajba-Făcăi Lacustrine Complex (Code 2394, Law 5/2000). The area is located in the central-eastern part of Dolj county (Romania), northwards of Preajba settlement and less than 10 km far from the city of Craiova. The authors present a floristic inventory that brings together the aquatic and marsh species within the territory under study, the corresponding distribution in the area being mentioned for each of them. The presence of certain taxa of sociological importance in the flora of Romania (e.g. Cirsium creticum) is noted, while the presence of others in the spontaneous flora of Oltenia (e.g. Vallisneria spiralis) is reconfirmed. Moreover, the authors discuss the influence of the anthropic factor on this area, in conjunction with the effects of climate changes, which are increasingly visible.

MICROBIOLOGICAL ANALYSIS OF SOME VEGETABLE SPECIES COMMERCIALIZED ON LOCAL AND SUPERMARKET MARKETS

2024-11-24T08:38:10+00:00

Fruits and vegetables are an important part of the human diet, providing essential vitamins, minerals and fiber and adding variety to the diet. In the Food Guide Pyramid, the US Department of Agriculture encourages eating 3-5 servings of vegetables and 2-4 servings of fruit per day (León J.S, 2009). The present study aims at microbiological analysis of frequently consumed vegetables. It was found that the highest loading was on cucumbers and lettuce and the lowest on peppers and tomatoes. Refrigerated storage for 7 days resulted in an increase in the number of microorganisms

OBSERVATIONS ON THE STRUCTURE, DYNAMICS AND ABUNDANCE OF ARTHROPOD SPECIES FROM POTATO CROPS IN RĂDĂUTI AREA, SUCEAVA COUNTY

2024-11-21T06:23:42+00:00

The collection of the material was done with the help of Barber pitfall traps in a potato crop in the NE area of Romania, in the town of Rădăuti. Suceava county. The observations were made in 2022 in an autumn potato crop, the Gared variety using 3 experimental variants:
- V1- potato grown in ecological system (with treatments approved in ecological agriculture); - V2- potato grown in a conventional system (with chemical treatments);
- V3- potato cultivated without treatments.
For each variant, 12 traps were used placed on two rows at a distance of 10-12m between traps per row and at 6-8m between rows. The material was collected from May to September, making a total of 4 collections. The determination of the collected material was done with the help of determinants and specialized sources on the Internet. The collected arthropods belong to the following groups: insects and mites.

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

2024-11-23T06:52:52+00:00

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.

WOODEN MATERIALS USED IN LANDSCAPE APPLICATION IN CRAIOVA CITY

2024-11-23T06:39:08+00:00

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

2024-11-24T06:08:16+00:00

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

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

2024-11-24T08:16:46+00:00

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

2024-11-20T16:22:43+00:00

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

2024-11-23T06:25:37+00:00

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.

PHOTOSYNTHESIS ACTIVITIES OF MELON CULTIVARS UNDER FLOODING ENVIRONMENT

2024-11-24T07:24:29+00:00

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.

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

2024-11-21T09:35:07+00:00

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

2024-11-23T07:02:32+00:00

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.

2024-11-24T07:47:08+00:00

Stored grain pests, particularly Tribolium castaneum and Tribolium confusum, pose significant threats to grain storage facilities. This study examines their populations before and after phosphine fumigation in a wheat mill near Bucharest, Romania. Monitoring was conducted over four months using XLure Rusel MST pheromone traps. Results revealed a 97.14% reduction in total insect population, from 1,606 to 46 individuals. However, surviving populations were noted, indicating potential resistance to phosphine. This study underscores the persistence of pest populations and the necessity for continued monitoring and research on resistance mechanisms in real-world settings.

OBSERVATIONS ON THE EXISTING FAUNA IN APPLE ORCHARD

2024-11-20T15:49:17+00:00

The observations were made in an apple orchard in Nechit, Neamț county.To collect the studied entomofauna, Barber-type soil traps were used, which were placed in the plantation in number of 12. 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

2024-11-21T22:37:49+00:00

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

2024-11-24T07:01:09+00:00

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.

2024-11-19T14:34:59+00:00

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

2024-11-19T10:36:35+00:00

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

2024-11-19T10:11:37+00:00

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.
