The purpose of this paper is to evaluate from a nutritional, phytochemical, and rheological point of view different varieties/lines of oats cultivated in Romania. In this sense, the proximate composition (proteins, lipids, mineral substances, starch, and carbohydrates), the total polyphenols content (TPC) of individual polyphenols and macro and microelements of 20 oat varieties/lines were determined. In order to evaluate the potential for use in the flour industry (pasta, bread, and biscuits)., a variety of oats with optimal nutritional properties and active principles was used to obtain oat/wheat composite flours in different proportions (10–30% oat flour) and subjected to rheological analysis using the Chopin Mixolab test (Chopin Technologies, Paris, France) The results showed a protein content between 14.36–17.08%, lipid content between 6.01–9.03%, starch between 44.13–52.95%, total mineral substances between 0.93–1.65%, carbohydrates between 65.16–69.32% and energy value between 389.81–409.86 kcal/100 g. The TPC content varied between 614.76–1244.58 µgGAE/g, and the average values of individual polyphenols were between 1.87 μg/g (rosmarinic acid) and 28.18 μg/g (gallic acid). Regarding the macroelements content, potassium (K) was the major element (203.19 μg/g), followed by calcium (Ca) (181.71 μg/g) and magnesium (Mg) (105.79 μg/g). The level of microelements varied between 3.02 μg/g for nickel (Ni) and 60.25 μg/g for iron (Fe). Multivariate data analysis PCA was used to correlate the obtained data. The rheological analysis using the MIXOLAB system proved that, from the point of view of technological properties, composite flours from a mixture of 10–30% oat and wheat flour are the best for obtaining biscuit dough, compared to pasta or pan bread. Following the study and based on nutritional, phytochemical and rheological results, line 2511 was selected as optimal for use in obtaining hypoglycemic flour foods for people with diabetes.

In any region of the globe, the cultivation of industrial crops, including hemp, imposes certain conditions related to relief, climate, hydrology, or soil. The interrelations between these factors lead to differentiations regarding the establishment of cultivation zones and implicitly in terms of productivity. This study aimed to identify suitable areas for hemp cultivation and generate favorability maps in western Romania, based on GIS and MCDA techniques. Ten factors, significantly important for hemp cultivation, related to relief, climatic conditions, soil, and human intervention were considered. Following spatial analyses using the Weighted Overlay Analysis (WOA) method, the territory was classified into four zones: Zone I, with highly suitable lands (26%), located in the western half, overlapping with plain areas and river valleys; Zone II, with moderately suitable lands (28%), located in regions of high plains and hilly areas; Zone III, with marginal lands (3%), located in some depression areas, hilly areas, or at the contact with pre-mountainous areas; Zone IV, with unsuitable lands for hemp cultivation, in mountainous areas, under restrictive environmental conditions. The obtained results can be used in land management strategies or by farmers for estimating available land resources. [ABSTRACT FROM AUTHOR]

Cannabis sativa L. is one well-known medicinal plant that has attracted interest recently and throughout the years. Our research aimed to highlight the antimicrobial activity of hemp seed oil, the Mara variety cultivated under the conditions of the University of Life Sciences in Timisoara, on 12 microbial strains. The results demonstrated antimicrobial efficacy dependent from one species to another, as follows: an upward trend, positively correlated with the concentration increase tested in the case of: Streptococcus pyogenes, Staphylococcus aureus, Shigella flexneri, Pseudomonas aeruginosa, Salmonella typhimurium and Candida albicans with MIC between 0.2 mg/mL-8 mg/mL. As well as a downward trend, negatively correlated with concentration in the case of strains of Escherichia coli, Listeria monocytogenes, Haemophilus influenzae, Bacillus cereus and Candida parapsilopsis, where MIC was present starting with the concentration of 0.2 mg/mL. In the case of certain strains (Clostridium perfringens), Cannabis sativa L. oil showed a pronounced strain-boosting effect, with significant stimulation of bacterial growth. The results support further research into the effect of Cannabis sativa L. vegetable oil as a potential antimicrobial agent for microbial strains. [ABSTRACT FROM AUTHOR]

The paper aimed to analyse the morphological characters for eight spontaneous populations of thyme, including an endemic population (Thymus comosus), collected from different regions of the Banat area. Both interpopulation and intrapopulation variability determinations were pursued, and results were correlated with statistical interpretations. Morphological analyses were carried out, including the shape of the leaves, as this morphological character is decisive in the taxonomy of the genus Thymus. Based on morphological similarity, the analysed populations were hierarchically classified, by the cluster mean method, in two main clusters. In the first cluster, six of the eight analysed populations were grouped, respectively those belonging to the species Th. praecox (with the two subspecies janke and polytrychus) and Th. dacicus. In the second cluster we find the endemic population of Th. comosus and the population of Th. pulegioides, which are 97.51% morphologically similar, but different from the populations found in the first cluster. The obtained data allowed the quantification of the associative relationships between the morphological parameters studied. [ABSTRACT FROM AUTHOR]

The aim of the work was to carry out a study on the influence of climatic conditions and fertilization with chemical fertilizers on wheat production in the specific conditions of Didactical Farm (SDE) of the University of Life Sciences "King Mihai I" from Timisoara (ULST). A Fundamental contribution to the increase of the yield per unit area is made by the level of N, P. K fertilization and optimal soil and climatic conditions for exploiting the productive potential of the cultivated variety. The high ecological plasticity of wheat and its constant productions means that farmers are still very interested in this crop. Growers are also interested in the crop with the highest yield per unit area. The aim of this paper is to highlight the yield results of Ciprian wheat variety, obtained in the soil and climatic conditions of SDE during 2019-2020, under the influence of nitrogen, phosphorus and potassium fertilization in order to determine the growers to choose an optimal wheat fertilization option. Wheat yield obtained was determined by nitrogen fertilizer application from the control variant as follows: N30-485gk/ha, N60-584 kg/ha, N90-605 kg/ha, at all four rates the differences are statistically assured as highly significant.

Hyssopus officinalis L. has a long and rich history as a medicinal plant due to the health benefits transmitted from generation to generation of usage as a carminative, antiseptic, and cough reliever. These benefits have drawn the attention of the researchers, whom, in the last years, have started to fundament scientifical elements of the hyssops crop technology. This study aims to follow and report the germinative capacity and both fresh and dry herba yield of three hyssops varieties (white, blue and pink). The assessing of herba yield, was done at SCDA Lovrin and the germinative capacity of the studied varieties was determined in the Laboratory for Seed Quality from the Faculty of Agriculture from Timisoara. The results are highlighting significant differences between the varieties regarding germinative capacity, the mass of 1000 grains and both dry and fresh herba yield. [ABSTRACT FROM AUTHOR]

In the last decades, the main meteorological parameters, namely the air temperature and the amounts of atmospheric precipitation, have registered significant variations, both from one year to another, and within the same year, from one season to another. In addition to the variable climatic conditions, specific to the Timiş Plain, in the case of the hemp culture, the ecological conditions specific to this culture must also be taken into account. Based on these considerations, the aim of the paper is to carry out a detailed analysis of climatic factors and their impact on the main stages of growth and development of hemp, under the conditions of Timisoara. The analysis of temperatures and atmospheric precipitation was done over a period of six years, respectively 2017 – 2022. Average monthly thermal values and the sum of precipitation amounts were extracted for each year considered. For the period 2017 – 2022, four bioclimatic indices were calculated, based on which the main meteorological parameters with an impact on the hemp culture were characterized. In order to monitor the dynamics of the hemp culture (Mara 21 Variety) during the vegetative cycle, the BBCH scale (proposed by Mishchenko et al., 2017) and the average daily temperatures were used, based on which the sum of the temperature degrees was calculated, for each stage phenological and during the entire vegetation period. In the Mara 21 hemp variety, a vegetative and a generative stage were determined in the 150-day vegetation interval. The sum of the temperature degrees from sowing to harvesting the seeds was 3372.30C. The research results support the idea of variability of climatic conditions, especially of the amounts of atmospheric precipitation in the analyzed territory, which is also reflected on the hemp culture.

Research developed in recent years underlines the importance of monoic hemp crops, both for economic values, in the agricultural field, and as an integrated substance in medical treatments. As in the case of other agricultural crops, for the analysis of the dynamics during a vegetation cycle of hemp crops, it is necessary to apply a well-established work flow, within an experimental device. In this context, through this study, a work protocol is presented through which the "classic" experimental technique is completed by geomatic means. The proposed work protocol involves a field stage, in which the experimental field is marked with GPS points and the sampling points are located with centimeter precision, which ensures the possibility of sampling from the same plant, in different phenophases. The second stage, the office one, involves: the graphic representation of the experimental site, based on the contour points marked in the field, and therefore the verification and validation of the necessary dimensions (dimensions between rows, free spaces, cultivated spaces, etc.); overlaying the experimental field with other thematic maps of environmental factors and thus extracting geospatial information (geology, climate data, soil, etc.) that complements the information collected directly from the field. To position the points in the field, GNSS equipment with a South receiver was used, with centimeter precision, and for data processing, AutoCAD Map 3D 2012 and ArcGIS 10.4 software were used. To extract the geospatial information, thematic maps in raster and vector format, taken from the specialized platforms, were used. The advantages of this working protocol consist in: locating with topographical precision the experimental device and the sampling points; the extraction of environmental data, point by point; the possibility of computerized comparison of the results obtained in different phenophases; spatialization of results and analysis of crop dynamics, both in a vegetation cycle and in different years; cartographic representation of the experimental field.

The oil extracted from Camelina sativa seeds is underused and not well known, making the camelina crop a niche one. However, the oil is a potential source of omega-3, omega-6, and omega-9 fatty acids, so the crop has started to draw attention and occupy increasingly larger areas. This is owed to the multiple uses of the oil (in medicine, chemistry, energy), as well as the economic efficiency of the crop. The objective of this study was to determine which of the three different varieties, each one with different provenience and from different pedoclimatic conditions, has a better fatty acid ratio in the extracted oil. This study covers the results obtained in the laboratory research phase on a selection of three camelina varieties (Camelia, created by the University of Agronomic Sciences and Veterinary Medicine of Bucharest, Calena, with Austrian origins and a local population by BUASVM Timisoara) regarding fatty acid content. The oil extraction and further determinations were made in the research platform of BUASVM Timisoara. Results showed that there are no major differences between the camelina varieties, with omega-3 fatty acid content ranging from 28.48% to 33.62%, omega-6 values between 21.28% and 23.62% and omega-9 between 30.11% and 31.64%, although their origin is from different.

This study analyses the amount of total polyphenolic content (TPC) in dry plant materials collected from different populations of Thymus belonging to several spontaneous species from multiple regions of the Banat area. The aim of the research is to identify the quantitative differences of TPC in the thyme populations studied, regarding both the area and the species, or potentially subspecies. The TPC was determined with Folin-Ciocâlteu reagent using gallic acid as standard, and the concentration of ethanolic extracts was expressed in mg/g dry matter. The results obtained were statistically analysed using proximity matrices that indicate the similarity of the polyphenolic profile in the populations studied. The populations were classified clustered according to the similarity of the polyphenolic profile. The data obtained indicate significant differences in the polyphenolic profile at species and harvest area level. The possibility of using this indicator as a chemical fingerprint for the spontaneous thyme species from Banat was analysed. [ABSTRACT FROM AUTHOR]

In Romania a series of traditional herbs are grown - sage, mint, lavender, etc. for which agrotechnical processes have been developed. At the same time, research is being carried out to broaden the variety of herbs. [1] Monarda is among herbaceous plants whose healing properties were known in Antiquity. The flower is often used as a medicine, as well as added to foods as spices. Monarda was brought to Romania in the 19th century and, for a long time, it had a decorative use. The Didactic- Experimental Station in Timisoara, Romania, is, from a geomorphological point of view, part of the large physical-geographical unit "Banato-Crisana Field". The Didactic-Experimental Station is located in the south-western part of the country, benefiting from moderate continental temperate climate, with shorter and milder winters, frequently under the influence of the activity of cyclones and masses of warm air from the Mediterranean and Adriatic Seas. From the climate type map of Romania, it follows that the perimeter of the Didactic-Experimental Station falls within the moderate continental climate, the interference between the oceanic climate province sector and the climate province sector with sub-Mediterranean influences. The annual average temperature is 10.7°C, fluctuations from this multiannual average are a few subunits to 1-1.2oC more or less. During the period 1927-1996, the values of the annual averages show the following oscillations: 407.2 mm in 1983 and 908.1 mm in 1970. The biological material was produced by Dacia Plant Brasov. In 2014, the plants of Monarda didyma in the form of rooted cuttings were grown in the experimental field located in the "Young Naturalist Station" in Timisoara. The preparation of the ground for the establishment of the culture was achieved through the soil works specific to the technology of the culture. Rooted cuttings were planted on October 3, 2014, at a distance of 70 cm between rows and 40 cm between plants at a time. The Monarda didyma species was kept in the culture until 2016. In November, the rooted cuttings were transplanted into the experimental field of the Timişoara Didactic Station. In the Monarda didyma culture, care works were carried out to control weeds mechanically. During the growing season, phenological observations were made (flowering is staggered, taking place throughout June). [ABSTRACT FROM AUTHOR]

The current study aimed to investigate ethanolic extracts from the following medicinal plant species cultivated in western Romania: Melissa officinalis L., Rosmarinus officinalis L. (RO) and Salvia officinalis L. (SO). Antioxidant activity, total phenolics content and a profile of the main hydroxycinnamic acids (HCAs), including caffeic, ferulic, coumaric and rosmarinic acids, was determined for each plant extract. The in vitro antimicrobial activity against four bacterial strains (Escherichia coli, Listeria -, Pseudomonas aeruginosa and Staphylococcus aureus), and the effect on cell viability in two melanoma cell lines (B164A5 murine melanoma and A375 human melanoma) was also assessed. The results indicated that total phenolics content was 73.76-274.73 mg GAE·g-1 and the antioxidant activity was 2.32-2.87 mM Fe2+·100 g-1. There was found a strong positive correlation (R=0.9691) between total phenolics content and the antioxidant activity in the investigated samples. Regarding the HCA profile obtained by high performance liquid chromatography, the results demonstrated that rosmarinic acid represents the main identified compound. The ethanolic extracts of RO and SO exhibited antibacterial activity against Gram positive and Gram negative bacteria. RO was the most effective in terms of decreasing the cell viability of murine and human melanoma cell lines, while the HCAs did not exhibit any effect on cell viability. These findings suggest that plant extracts from the Lamiaceae family may used in the clinic as natural antibacterial agents. [ABSTRACT FROM AUTHOR]

Research on hemp breeding at SCDA Lovrin began in 1962-1964. From the beginning, the main objective was to obtain dioecious varieties for fiber production, an important part of the hemp from an economic point of view. The first variety of Lovrin 110 diocious hemp was approved in 1981, and was one of Europe's finest dioecious hemp varieties. Two more varieties of hemp followed: Silvana and Armanca. Silvana variety in quantitative and qualitative terms is currently considered as the standard for hemp in the EU. The research has been aimed at demonstrating the potential of stem production, fiber content, fiber production and seed production. The main objective of the paper is: The production potential of approved and cultivated dioecious hemp varieties and cultivation that serve the breeding process as the initial material.

Mountain or winter savory Satureja montana L. is one of the most cultivated aromatic plant from Lamiaceae family. As most of the species from their genus, Satureja montana L. contains essential oils which differ in chemical composition as plants are from different origin or has been dried in different regime. This study has been shown that chemical composition and antioxidant capacity are different for dry and fresh herba and even has been varying if the herba was dried in air or in the oven. It has been demonstrated that the major compound, carvacrol, of volatile oils from dry herba was found to be in higher percent than in volatile oils extracted from fresh herba. In contrast, different sesquiterpenes concentrations were higher for fresh herba. The antioxidant capacity was two times bigger for the oil extracted from dry herba. This surprising feature could be explained by the higher carvacrol concentration and lower thymol concentration determined in volatile oil extracted from dry herba. [ABSTRACT FROM AUTHOR]

Medicinal plants are grown in Romania for decades for the therapeutic proprieties, for essential oils and the antibiotic action. The aim of this research paper is to determine proximate composition (moisture, proteins, lipids, ash, carbohydrates) and the content of some elements (Mg, Ca, K, Zn and Fe) in medicinal plants species grown mainly in the western part of Romania, belonging to the Lamiaceae family. Herba from six medicinal plant species were collected during 2014 and was determined proximate composition (moisture, ash, lipids, proteins and carbohydrates) using official AOAC methods (AOAC, 1997) and elemental composition using absorbtion spectroscopy. The results revealed that the studied medicinal plants are good source of carbohydrates and nutrients, high K content followed by Ca, Mg, Fe and Zn. In view of above facts, the medicinal plants belonging to Lamiaceae family cultivated in west side of Romania show great promise as a dietary and therapeutic source involved in human health.

The importance of this study is to provide information for a future green solution to the toxic fungicides used in our days in crop and grain protection. Verticillium dahliae and Penicillium aurantiogriseum are very common in crop deposits and they are very hard to commbat even with synthetic fungicides. The aim of this research is to establish the minimum concentration of essential oil (EO) extracted from Origanum majorana L. which causes a fungistatic and fungicidal effect on Verticillium dahliae and Penicillium aurantiogriseum fungi. Previous research has shown the minimum inhibitory concentration of the Origanum majorana L. EO over Verticillium dahliae but not on Penicillium aurantiogriseum. Also we can say after reading more research papers that the chemical composition of the EO depends on the site of cultivation, climate conditions and the time of harvest. The tested medical plant,Origanum majorana L., was grown in a temperate climate zone in Timisoara, Romania (21013`E longitude, 45045` N latitude). At the time of harvest Origanum majorana L. was in the 4th year of vegetation. Identification of the species was confirmed by the department of Aromatic plants from USAMVB Timisoara. We obtained the EO from the dry herb using a volatile oil distilling Clevenger equipment. The chemical composition of the EO was determined using gas chromatography/mass spectrometry (GC/MS) analysis. The tests made in vitro on CYGA medium, with additional oil at 0.25 mg·L-1; 0.5 mg·L-1; 1 mg·L-1; 5 mg·L-1; 10 mg·L-1 and 15 mg·L-1and 20 mg·L-1 concentrations and inoculated with plugs harvested from a young mycelium, revealed a different reaction of the fungus depending on the oil concentration. The value of minimum inhibitory concentration (MIC) has been established after 14 days after verifying the restauration of hyphae and mycelium of fungi. The MIC value for Verticillium dahliae was 5 mg·L-1 Origanum majorana L. EO (essential oil). The MIC value for Penicillium aurantiogriseum was 1 mg·L-1 Origanum majorana L. EO (essential oil). The MFC(minimum fungicidal concentration) value for both Verticillium dahliae and Penicillium aurantiogriseum was 20 mg·L-1 Origanum majorana L. EO. [ABSTRACT FROM AUTHOR]

The aim of this research study is to establish the minimum inhibitory concentration (MIC) of the Salvia officinalis L. EO cultivated in the western part of Romania wich causes a fungistatic effect against Verticillium dahliae and Penicillium aurantiogriseum fungi. Also we will determine the chemical composition of this tested EO.Verticillium dahliae and Penicillium aurantiogriseum are very common in crop deposits and they are responsible for the degradation of the grains after the harvest. This research is carried for green solutions of crop protection, safe for human consumption and friendly for the environment. The antifungal activity of Salvia officinalis EO has been tested worldwide but the chemical composition and the MIC can vary due to the climate conditions, region of cultivation and the time of harvest. Further research has to be made to extract and create the optimal combination of chemical compunds from the EO that inhibits the growth of seed borne fungi. Salvia officinalis L. was grown in a temperate climate zone in Timisoara, Romania. The harvest took place in May 2014 during the blooming period after a sunny period of time. At the time of harvest Salvia officinalis L. was in the 4th year of vegetation. The tests made in vitro on CYGA medium, with additional oil at 0.25 mg·L-1; 0.5 mg·L-1; 1 mg·L-1; 5 mg·L-1; 10 mg·L-1; 15 mg·L-1 concentrations and inoculated with harvested plugs from a young mycelium, pointed out a different reaction of the fungus depending on the oil concetration. The value of the minimum inhibitory concentration (MIC) has been established after 14 days. Restauration of hyphae and mycelium of fungi was verified. The MIC value for Verticillium dahliae was 10 mg·L-1 for Salvia officinalis L. EO. Penicillium aurantiogriseum had a very similar sensitivity to the Salvia officinalis L. EO, therefore the MIC value was 10 mg·L-1 guaranteed for a period of 14 days. [ABSTRACT FROM AUTHOR]

Situated in the SE of the Timis county, the Niţchidorf locality benefits from a favourable position from an economic and social point of view. Only 33 km away from Timişoara and 9 km from the Buziaş resort, Niţchidorf is situated in the Bârzavei Plane, on the Pogăniş river. The closeness to the Buziaş Resort, as well as the Natural Reservation Lunca Pogănişului creates opportunities for agritourism development in the area. The locality benefits from soil and water resources, for the obtaining of quantitatively and qualitatively significant crops, but, unfortunately, the human and technical resources are insufficient. The active locality population is decreasing in number. Accessing governmental and European projects could lead to agricultural development, obtaining high productions and protecting the environment by practicing an ecologic agriculture. The agricultural system in Niţchidorf is agri-zootechnical mixed one, but with pomiculture and pisciculture developing tendencies. [ABSTRACT FROM AUTHOR]

The Seleuş commune is situated on the Eastern side of the Crişului Alb Plane, on the Cigher river. It is situated 12 km away from Ineu, 6 km from Pâncota and 45 km away from the city of Arad. It is also crossed by the Cigher river, the Morilor Canal, Crişul Alb to the North and the Matca Canal. The Seleuş commune comprises three localities: Seleuş, Moroda and Iermata. The commune borders on the Pâncota and Ineu towns, a fact that has influenced its economical and social development. The first documented attestation of the Seleuş locality dates from 1489. The Iermata village is first documented in 1387, and the Moroda village 1508. The locality is situated in the Crişurilor Plane in the centre of the Arad county. Thus, we are dealing with the Western Plane's low altitude, with soil predominantly from the 1st and 2nd fertility groups, favourable for doubling the current cereal, technical plants and vegetables, with sub-hilly land and those in inter-mountain depressions, where large cattle, pomiculture and, at large, viticulture have represented the blazon of these region for centuries, and alpine grasslands, where sheep breeding is a part of history.

Introduction: Lichen planus is a benign papulo - squamous dermatosis with a muco - cutaneous involving that affects 1 - 2% of population. Neoplastic transformation of lichen planus lesions occurs very rarely, being described especially in oral lesions. Malignant transformation of cutaneous lichen planus lesions, although very rare , has been described in isolated cases of chronic hypertrophic lichen planus localized on lower limbs . Clinical case: We present the case of 49 years old female patient , diagnosed with lichen planus with onset in adolescence , which was consulted for a deep ulceration localized on the internal aspect of the right calf, with onset of about a year that led to observe the underlying muscle and tendon structures . No inguinal lymphadenopathies were found . Erythemato - violaceous , itchy, plane papules and residual hyperpigmented macules were noted o n the wrists and forear ms, and large brown pruritic papules on the dorsal side of the feet and the internal aspects of the calves were observed. Oral and genital mucosas were normal. Histopathological examination of skin biopsy sample taken from the superior edge of ulceration shows a moderately differentiated squamous cell carcinoma . Due to the large size of the tumour surgical excision was not possible opting for amputation o n the middle third of the right thigh . Discussion: This case is presented in order to emphasize the possibility of squamous cell carcinoma arising from a lichen planus skin lesion , especially when it comes to the persistent lesion , nonresponsive to treatment . This type of lesions should be suspected of malignancy transformation requiring a biopsy to rule out a possible squamous cell carcinoma . [ABSTRACT FROM AUTHOR]
