THE ASSESSMENT OF VARIABILITY FOR SOME MORPHOLOGICAL AND QUALITY TRAITS OF FRUITS IN DIFFERENT CULTIVARS OF STRAWBERRY pag. 3-8
Natalia CARP*, S. CIULCA*Abstract. The commercial value of strawberry cultivars depends mostly on the appearance of the fruit and their quality, mainly their size and sugar content. The aims of this study were to assess the morphological and quality fruits traits of eight strawberry cultivars with different genetic and ecologic origin. The highest variation among the studied varieties was recorded for fruits shape and inner cavity size, but those characters had a lower influence on fruits weight variability. For this set of genotypes, the fruits diameter has contributed more than their length to achieve their weight. Also, the sizes of the fruits are negatively correlated with the sugar content. Cultivar Elsanta’s sugar content was significantly higher than all the other varieties and was associated with elongated fruits shape of small size. The biggest fruits were observed in genotype A2, which has a flattened shape fruits with a full pulp, but characterized by lower than average sugar content. The results indicate that there is a considerable variability between the studied cultivars that can be exploited in strawberry breeding programs for quality traits.

DownloadMONITORING OF HEAVY METALS RESIDUES IN HONEY pag. 9-13
Oana CIOBANU, Hortensia RĂDULESCUAbstract: Honey and bee products have the image of being natural, healthy and clean. However, today bee products are produced in an environment polluted by different sources of contamination. The main sources for contamination of honey with heavy metals are represented by placing hives near urban areas with heavy car traffic, or industrialized areas and the use on the entire circuit of production, objects or containers made of materials unsuitable (unacceptable). The research from the topic announced was conducted in research laboratory of the Agrochemistry Department from the Faculty of Agriculture. The purpose of the paper is to observe specific variations in the containt of heavy metals of honey, following differentiated location of the hives. We consider 2015 the year when hives were placed in areas with differentiated impact of pollution, making it possible to identify the influence of the pollution sources mentioned on the quality of honey, by identifying residues of heavy metals.

DownloadBRIDGING THE GAP BETWEEN TEACHING LANGUAGE AND TEACHING CULTURE IN A FOREIGN LANGUAGE COURSE AT THE FACULTY OF AGRICULTURE pag. 14-18
Laura COROAMĂDecades ago teaching a foreign language was exclusively linguistic oriented. Nowadays, more and more approaches recognize the holistic aspect of language learning. In spite of this acknowledgement, current textbooks and curricula do not contain specific information in order to familiarize students with the cultural implications connected to learning a foreign language. The aim of this paper is to raise awareness on the advantages of integrating cultural concepts and topics within the French course at all levels. Cultural knowledge should become a significant part of students’ academic culture as it represents a major landmark in their future development.

DownloadMONITORING OF THE SOIL FERTILITY IN LUGOJ HILLS pag. 24-28
Alina LAȚO, Isidora RADULOV, Adina BERBECEA, L. NIȚĂ, F.CRISTA, I. LAȚOIn terms of geomorphology, the investigated area belongs to the large physical-geographical unit "Banato-Crisana" taking place in the interim relief stage between Western Carpathians and Pannonian Depression edge. Within that sector in which the investigated area meet the following forms of relief: hill, terrace, plain ramble, meadow. Geologically investigated area is part of the Pannonian Depression, its eastern end, which was formed by the gradual silting of the lake in "Pleistocene-Quaternary". Appropriate geological formations mentioned in the soils identified and delineated in the investigated area have generally found the following main groups of parent materials: loam, clays and fluvial deposits. Lugoj hills cover an area of 10.676.33 hectares. The main soil types in the investigated area are stagni-gleyic phaeozems an area of 4.97 ha (0.05%), haplic luvisols on 713.34 ha (6.68%) to 5822.63 ha, typic hapludalfs on 6286.05 ha(55.84%) , haplic planosols on 488.25 ha (4.57%), typic eutrocryepts on 1326.68 ha (12.43%), haplic stagnosols on 301.77 ha (2.83%), haplic gleysols on 426.07 ha (3.99 %), pellic vertisols on 364.47 ha (3.41%) and haplic fluvisols on 625.87 ha (5.86%). This paper is a study of soil fertility improvement methods in Plain River. The different types and groups of genetic soil types existing today in the perimeter are the result of the actions sought in time and space complex pedogenetic factors (underlying rock, landscape, climate, vegetation, hydrography, hydrology, fauna) plus the influences caused by human actions from draining and drainage works to intensive agriculture today. Soils formed in these conditions are a relatively recent stage of soil formation as a result of having little time out of the water. The process of soil formation is relatively recent and their direction of development is dictated largely by the microrelief forms they occupy and thus the groundwater level in the profile, and the nature of parental rocks.

DownloadMETHODS OF ASSESSMENT USED IN THE AGRONOMIC HIGHER EDUCATION pag. 29-33
Iasmina Cecilia SAVESCU1 ,Narcisa Georgeta CRISTA1 , Cristina TULBURE1The educational assessment represents the process of measuring the quality of educational processes or products. In the higher education space, the assessment process of students’ achievement holds a central role, as it is a guide for the students’ and teachers’ future activity. In this respect, our study aims to determine the most commonly used assessment methods at an agronomic faculty and to identify the students’ perspective concerning the most appropriate assessment methods. This study was accomplished during the second semester of the university year 2015-2016, on a sample of 64 pre-service teachers attending the first year of study at the Faculty of Agriculture of a Romanian university. The data was collected using a questionnaire of opinion as a tool, which contained a total number of 6 items, 4 items with closed, pre-coded answers and 2 items with open answers. The data analyses revealed the fact that most of the assessment methods in use are traditional (oral, write, practice examinations) and from the category of alternative methods only the portfolio and the project, and rarely, the investigation are used. The students think that it would be very useful for them to use more investigations, case studies and cognitive maps in order to assess their capacities and competencies. The results bring some openings to the theoreticians and practitioners involved in university education, and meet the need for an assessment methods diversification in tertiary education.

Renata Maria ŞUMĂLAN1*, R.L. SUMALAN1, L. COPOLOVICI2, S. CIULCA1, JC. YVIN3, Adriana CIULCA1In Romania the most infested fields with Orobanche cumana are situated in South-Eastern part of the country especially in Buzau, Tulcea and Constanta county. Our study assesses the influence of Orobanche attack on sunflower oil quality. We have used two sunflower hybrids MAS95 IR and MASS 83R from Maisadour provenance in a field experience through randomized blocks design. The location was on the Casimcei plateau, in vicinity of Sarighiol de Deal, Tulcea county. There were no mechanical or hand hoeing, not applied herbicides or any other insecticide and fungicide treatments in sunflower vegetation period. In September twenty five of sunflower heads were harvested from each hibrid, samples from parasitized sunflower plants and non- parasitized by broomrape respectively. The sunflower oils have been obtained by chemical extraction. The fatty acid profiles were analyzed by GC-MS. The results have revealed that the linoleic acid is the prevalent fatty acid in seeds. Sunflower plants parasitized with broomrape were not affected from point of view of palmitic and stearic acid contents, but in case of oleic and linolenic acids are noted increases of contents. The differences are variable depending on genotype profiles of plants.

S. DRÉANO1, F. PRUNAR2, J. BARLOY3, Frédérique BARLOY-HUBLER1,4, Aline PRIMOT1Abstract. C. (Mesocarabus) problematicus Herbst 1786 is a fairly widespread European endemic species, especially on the Atlantic coast from the northern of Spain until Scandinavia. A recent map, based on the most recent data establishes the geographical distribution. From the eight European subspecies, the most isolated are the island subspecies, those from Faroe Islands (ssp. feroensis Lapouge, 1910) and Iceland (islandicus Lindroth, 1968) but also one continental subspecies from Romania (holdhausi Born 1911). Well represented in Western Europe, particularly in France (3 subsp.), the C. (Mesocarabus) problematicus Herbst 1786 species becomes very localized by going towards the East where is represented only by some relicts stations in Hungary and in Romania. In the last one the represented taxon holdhausi Born 1911, is quoted from eight localities among which two recent confirmed, all situated at high altitude (on 1500-1700 m). This fragmentation of the distribution and the localization in the mountainous zone pose two major questions: causes and anteriority of this residual localization in the refuges zones; genetic origin of this taxon and its link with the other forms of the species. The study wants to establish the position of the endemic taxon holdhausi (collected in the Mountains Hășmaș, Bucegi) among 71 populations of C. (Mesocarabus) problematicus from Western provenances, mainly French, basing on molecular biology data (mitochondrial marker primarily COI I, cyt b; secondarily ND1, ND4, ND5). The results with cyt b, the most selective marker, indicate: a big difference of maternal origin in Spain for the region pre-Pyrenees where appears ssp. planiusculus Haury in Gehin, 1885 and in France for the mountainous regions of the Massif Central (Sidobre, Montagne Noire), the Alps of Queyras of old forest from Centre-West, Italy in the Dolomites. The Romanians provenances from Bucegi and Hasmas are genetivaly close and neighbours of the majority of Western origins. These preliminary results incite to intensify the prospecting in Romania and nearby countries (HR, CZ, SK).

DownloadASSESMENT OF LAVENDER AND OREGANO ESSENTIAL OILS CAPACITY TO INHIBIT THE GROWTH OF POSTHARVAGE PATHOGENS PENICILLIUM EXPANSUM LINK. AND BOTRYTIS CINEREA PERS. pag. 60-67
Otilia COTUNA 1, Mirela PARASCHIVU 2, Veronica SĂRĂȚEANU 1, Carmen Claudia DURĂU1, Ilinca IMBREA 1Abstract. Research about antimicotic action of essential oils has been made for long time, but still little knowledge is available. Thus, there is particular interest especially for those postharvest pathogens that are difficult to be controlled. Some research emphasized high potential of essential oils to be used successfully against postharvest pathogens instead synthetic fungicides. Among the pathogens controlled by essential oils are known Botrytis cinerea, Penicillium italicum and Penicillium digitatum. The aim of this research was to assess the capacity of lavender and oregano essential oils to inhibit the mycelial growth of Penicillium expansum and Botrytis cinerea. Tests were made with oils in different concentrations and pathogens were isolated from the fruits skin and grown on specific medium being assessed the rate of mycelial growth. For both Penicillium expansum and Botrytis cinerea the rate of mycelial growth for control (no treated) was 0.29-0.30 mm/h. When 10 ml of essential oils were used it was observed that the rate of mycelial growth was very low for both pathogens, respectively 0,016 and 0,008 mm/h for Botrytis cinerea and 0,017 și 0,005 mm/h for Penicillium expansum. The inhibition rate was up to 90% for both pathogens, respectively 92,5% when lavender oil was applied, respectively 97.22% for oregano oil treatment. The results of the study emphasized that lavender and oregano essential oil had a significant impact on the inhibition on the growth of Botrytis cinerea și Penicillium expansum which can be an effective option for biological control of postharvest pathogens, substituting chemical fungicide control.

DownloadMONITORING OF THE INDICES OF BREAD ON AN ASSORTMENT OF COMMON WHEAT AND FLOURS OBTAINED FROM THESE pag. 68-77
Gh. MATEI , Ana Maria DODOCIOIU1Abstract.Nowadays, the most important elements necessary to obtain a quality wheat are genetic traits of the variety, the fertilization level, treatments against diseases and pests, favourable climatic conditions. We must not neglect other technological elements, but without accurate and timely compliance with the four items above, there is no chance to obtain a quality wheat. Variety is the first issue that must be careful in the establishment of a culture and especially its genetic heritage – it is or not a variety suitable for yielding quality wheat for bread. Regarding quality testing for most raw materials used in the food industry it meant the passing years do not necessarily reduce the number of methods of evaluation thereof. Or wheat flour have been no exception to this rule, so we currently have a growing number of methods for analysing technological qualities. Unfortunately, that method of analysis that says everything about how it will behave flour in the process of all methods Philosopher's Stone, was not invented yet. Optimal amounts of grain with problems in the enzymatic parameters (index falls, deformation index) required for obtaining various mixtures must be established for each case by laboratory tests. A higher percentage of 5% grains with 62 seconds falling number should be avoided, even if apparently resulting mixture has a good index dropping according to the literature (200-250 seconds). Flours obtained thus have poor technological performance, even if apparently all other quality parameters (including alveograph and farinograph) seems to be optimal. This is due precisely to the fact that the new conditions arise industrial flow (breeding, temperatures, pH, enzymatic equipment yeast and so on.), capable of intensifying the enzymatic activity levels beyond determinable by simple testing in laboratory or pilot (baking test).

DownloadSTUDY ON QUALITY OF DIFFERENT MALT TYPE USED IN BREWING INDUSTRY pag. 78-86
Gh. MATEI , Ana Maria DODOCIOIUAbstract. Research has led to the conclusion that beer is the oldest drink produced by man. The first evidence about beer dates back 4,000 years. It is assumed that Mesopotamia is the land where this liquor has been produced for the first time. Her discovery was completely accidental: a harvest of barley bread-making, devastated by rain to germinate. Exposed to the sun, germinated barley is contaminated with yeasts naturally present in air and thus was born beer. The main raw materials used in brewing and malting industry are: barley, common hop, water and malt substitutes (Felicia Stoica, 2012). Malt is a product made from grains (mostly barley) sprouted, dried and milled, used in the manufacture of beer and spirits or fried for the preparation of a coffee substitute (Romanian DEX, ed.1998). It is the main raw material used in the manufacture of beer, it is a source of substances into the substrate and a source of hydrolytic enzymes which by their action on the substrate leads to the formation of the production of worth extract. In brewing, malt is analysed chemically and physically. It is estimated the appearance, size, uniformity of grain, colour, purity, smell, taste and resistance to crushing teeth. Malt grains must be as large and smooth. The main chemical constituent of the barley, the starch is in the form of granules located in the cells of the endosperm. The beads of different sizes have a structure midsole, semi-crystalline, consisting of concentric layers formed on a spot. The structure is broken when grain absorbs water, it swells and hot, its components gelatinizes chemicals. From the chemical point of view, the granule is composed of 17-24% amylose, 74-81% amylopectin and 2% of other substances (polar lipid, protein substances, and minerals). Nitrogenous substances can quantity vary greatly with variety and related to the pedo-climatic conditions. Thus, for malting barley, malt and especially for obtaining blonde beers, should contain dry substance from 9 to 11.5%. Although the amount of protein in a barley only 1/3 pass into beer, they have a great influence on beer quality, affecting the colour, fullness of taste, foaming characteristics, its colloidal stability of beer and flavour (Banu C., 2009).

Mihaela CORNEANU1, C.NEŢOIU2*, Mihaela-Liana FERICEAN2, Cornelia HERNEA1, I. SĂRAC1, C. STROIA1In Romania, the interest for biomass production from short rotation coppice (SRC) is at beginning, being focused on the culture of poplar and willow. The high productions of biomass, which can be obtained from these cultures, are affected by numerous diseases and harmful insects, with negative effects on viability and vitality of these cultures. In order to improve the actual clones (certified for culture in Romania) resistance to biotic and abiotic stress, a collection of different provenance Salix sp. potential genitors was established in March 2015 (Didactical and Experimental Station belonging to BUASVM Timişoara). The genitors collection includes 38 genotypes collected from the spontaneous flora belonging to 11 different species of Salix. Diseases of shoots and leaves caused by Marssonina salicicola, Pollaccia saliciperda, Uncinula salicis and Cercospora salicina were registered. A negative impact on young shoots vitality had leaf beetle Melasoma saliceti L., small poplar borer (Saperda populnea) as well as sucking pests like different species of Aphidae or mites. The most tolerant genotypes both to pests and diseases were belonging to S. rosmarinifolia and S. pentandra. The most sensitive species include genitors from S. fragilis, S.alba and S.purpurea. Tolerance to pests and diseases was dependent on species and origin. The genitors will be monitored in the coming years for an accurate assessment of tolerance to diseases and pests, in different climatic conditions.

A. ŞMULEAC, C. POPESCU, C. BÂRLIBA, G. POPESCU, Laura ȘMULEACThis paper presents topographic surveys for the road section starting from the crossroad of county roads DJ582 from Resita to Gărâna with DJ582D leading (after turning right from DJ582) to Lake Gozna, Caraş-Severin County, a lake covering 60 ha and measuring 3 km in length. Why this topographic survey? Simply because there are numerous videos, comments and TV programmes on the road section between DJ582 (leading to Slatina Timiș) and the road section DJ582D 4 km from the Village of Văliug and leading to Lake Gozna, along about 700 m, water “flows up the hill” as witnessed by people and videos. Topographic survey necessary to carry out this study was done with a total station Leica TC805 and with an equipment of the GPS Leica 1200 type. The elevation measured with the GPS Leica 1200 equipment at the crossroads of the two roads DJ582 and DJ582D is 605.63 m and that of Lake Gozna is 601.61 m; this points to a level difference of 4.02 m for the county road DJ582D with a slope of 0.6% and a level difference of 9,51‰ for the collecting basin furbished by covering the slopes and the bottom of the canal on the left side of the county road DJ582D when going to Lake Gozna (Văliug) and stretching between 605.63 m at the crossroads of the DJ582 with DJ582D and 599.38 m at the entrance of the collecting canal into Lake Gozna. The claim that on this road section of about 700 m water “flows up the hill” is false. Parallel with the DJ582D on the left along the entire road is a canal that “goes upwards” according to some, but the difference between the two elevations (start and finish) is 6.25 m, the lowest elevation being determined at the entrance of the canal water into the Lake Gozna and the highest elevation being determined at the crossroads of the two county roads. To carry out the topographic survey, we chose for the total station a road supported at both ends by known coordinates and orientations. The station points were determined with GPS Leica 1200 equipment through the RTK (Real Time Kinematic) method. Besides measurements with a total station, where possible, we used for the measurements a double frequency GPS Leica 1200 equipment to determine both the four station points GPS1, GPS2, GPS300 and GPS400, and to survey the land using the reference stations in Reșița and Făget. Downloading the apparatus was done with a Leica Geo Office Combined programme and turning raw coordinates from WGS 1984 into stereographic coordinates 1970 was done with a TransDatRO programme. In the case of the total station, land measurements were made in a local reference system using as starting coordinates for the station point GPS1 X(m)=20.000, Y(m)=10.000 and for the elevation Z(m)=100. Compensating raw data was done with a TopoSys programme, reporting compensated values and making situation plans was done with TopoLT, and AutoCAD programmes. Road and canal profiles were done with a LISP and a ProfLT programme.

Similar surveys have been completed and NITA L., I. Rusu, V. Stephen (1999) on a haplic chernozems within SD Timisoara, applying fertilizer at different doses in maize. As material and research methods were used in the laboratories of Physics specific soils. In general, the results showed values of density, bulk density and porosity of the soil, area in the two years of research, to the culture of lettuce, cucumbers and on the. Lower values were recorded in March and higher in May October, so disturbed soil, registered values ranging from 2.43 g/cm3, the salad and 2.48 g/cm3, cucumbers. Soil bulk density, registered values ranging from 1.12 g/cm3, lettuce crop, in March 2014, and 1.20 g/cm3, the culture of cucumbers in the month of October. The total porosity, 50% had values, the salad, in March 2014. Aeration porosity, had values of 14.40%, cucumbers, during the month of March 2015. The paper is of great practical significance, because by knowing the physical properties of the soil can occur, if necessary, so that the values can be recorded in accordance with the requirements of the plants. The paper also has a scientific relevance, many authors consider that, knowing the physical properties of soils are more important than those chemical fertilization whose correction and amendment is easier to achieve. The work is a continuation of other studies and research achievement in physics soils, soils with different properties, so as to know more about the properties of each type and subtype of soil and can recommend crops that are suitable for each ground separately, in view of the species and the physical properties of soils studied.
