Abstract: Photosynthetically active radiation represents an ecological basis for determining the distribution of plants and favourable areas to different crops. The aim of this paper is to observe the direct influence of radiation on the development of crops. We used data on 25 years and calculation methods for the statistical knowledge of radiation and its distribution to specific hours. Here were performed on measurements of solar direct radiation and diffuse solar radiation, then we calculated the photosynthetically active radiation on basis of which we managed to make some estimation on the amount of energy that occurs in costal areas, how it is distributed over a period of one year and certain times characteristic. In this way we manage to make a concordance between the distribution of photosynthetically active radiation and the vegetation period of crops.

Abstract: Sheep are considered as an important livestock species in Albania and Kosova. Bardhoka is an autochthonous breed and is the most milk productive sheep among the long tail breeds that lives in both countries. Our study aimed at comparative analysis of microsatellite polymorphism in 6 loci in Bardhoka sheep breed in Albania and Kosova. It is the first time that these local populations of Bardhoka breed from two countries are compared based on DNA markers. It is analyzed genetic diversity of these populations. Allele diversity, observed heterozigosities, expected heterozigosities, F-statistics, GST estimates is calculated, using different software package. A total of 72 alleles were found. The average number of alleles per locus was 8.15. Within breeds, the mean number of alleles ranged from 5.8 in population from Kosova to 7.66 in population from Albania. The Albanian population has higher values of expected and observed heterozigosity, higher allele number and higher FIS value. Mean expected heterozygosity (He) ranged from 0.68 in Bardhoka from Kosova (Kobar) to 0.76 in Bardhoka from Albania (Albar). Both populations showed a significant heterozigote deficit. Several factors that could cause this deficit are discussed. Gene flow (0.81) is rather low. The mean Fst (0.238) demonstrated that 76.2% of total genetic variation is due to genetic differentiation within each population. Genetic differentiation between populations was much higher than reported by other authors. Genetic differentiation might be caused by long term isolation of these populations and application of different breeding strategies in each country. The research will go further in the future, increasing the number of the markers.

Abstract: The paper is based on data collected in 112 winter wheat parcels and 97 corn parcels, in 2006 and 2007, according to the Göttingen method. The sampled parcels are mostly situated in plain area of the Timiș County. We divided weed species in significant and non-significant ones, the last ones with a minor contribution to the weeding degree. We consider as diversity parameters the species number per parcel (significant, non-significant, minimal, maximal, average values for each year) and the Shannon-Wiener index. In winter wheat fields we found an average number of weed species per parcels of 26.5 (in 2006) and 23.1 (in 2007), while in corn fields the values were of 22.2 (2006) and 17.5 (2007). The average number of non-significant weed species per parcel per year ranks from 5.5 (corn, 2007) to 7.7 (corn, 2006). The Shannon-Wiener index values ranks from 2.53 (corn, 2007) to 3.27 (winter wheat, 2007). We didn’t find strong correlations between the total weed species number per parcel and the corresponding Shannon-Wiener index values. We explain this by the variety of conditions and cultural techniques.

Abstract: Efforts to evaluate the biodegradation of chlorophyll in autumnal leaves continues. The chlorophyll biodegradation pattern was determined in Hamamelidaceae family. The chlorophyll biodegradation in Vitis vinifera var. Pinot noir autumnal leaves is the same as in the Hamamelidaceae species. The study was performed by LC/MS analysis. The chromatogram obtained for the Vitis vinifera var. Pinot noir autumnal leaf extract was compared with the chromatograms obtained for the Hamamelidaceae species, where the chlorophyll biodegradation pattern was determined. Using LC/MS analysis the chlorophyll biodegradation pattern was validated in Vitis vinifera var. Pinot noir autumnal leaves. The LC/MS analysis of autumnal leaf extracts will allow the identification of chlorophyll biodegradation products among other Vitaceae species.

Abstract: Invasive organisms are among major threats to biodiversity. Insects, due to their mobility and short life cycle represent a vast category of expanding organisms.  The black locust (Robinia pseudacacia) is also an alien species to Europe but due to the relatively long history of naturalization, it is integrated in most of central Europe landscapes. A process of natural enemy acquisitions is taking place and two new pests affect stands, hedgerows and windbreaks where R. pseudacacia vegetates: Parectopa robiniella and Phyllonorycter robiniella (Lepidoptera Gracillariidae). A heavy infestation mostly with the newly introduced Phyllonorycter robiniella was observed in western and central Romania during 2003-2004. In many cases, leaves presented also mines of Parectopa robiniella. The mines of Phyllonorycter robiniella were attacked by several natural enemies: birds predated pupae, Beauveria bassiana was isolated from mines where larvae mortality was reported and also pupae of parasitoids where found in several cases. Having the same target, the foliage of the host and being members of the same guild, mining insects utilize the same niche. The study is interested in separating the niche components, mostly spatial of the two species based on the analysis of the results of C score of association. The shape of mines and their extension on the leaflet blade were assessed using image analysis.

Abstract: The aim of this study is to isolate Staphylococcus aureus in cheeses stored in different temperature in some markets in Albania. In these markets the cheese is stored not in the good conditions and in some cases the cheese is sold no in refrigerated temperature. This study is developed from June 2007 to June 2008. We have analyzed 176 of different cheese samples, 72 of these samples were positive with Staphylococcus aureus. From these 48 were samples of cheese stored in temperature > 100C with microbiological level 102cfu/gr - 104cfu/gr, this temperature is favourable for the production of the toxin, and  24 were samples of cheese stored in temperature < 100C with microbiological level 102cfu/gr–105cfu/gr. This is due to contamination of the cheese with Staphylococcus aureus and its growth is favoured from the no refrigerated storage of cheeses.

Abstract: Oilseed rape/canola (Brassica napus) represents a potentially valuable source of vegetable protein due to its favourable composition of essential amino acids. However, the use of rapeseed protein for human nutrition is presently not possible due to the presence of major anti-nutritive compounds, which also reduce the value of rapeseed meal as a source of animal feed. Especially relevant in this regard are dietary fibre, dark-coloured tannins and bitter-tasting sinapate esters. Yellow coloured seeds are of particular interest for oilseed rape breeding because of their association with a thinner seed coat resulting in reduced dietary fibre and condensed tannin content. This considerably improves the feed and protein quality of rapeseed meal after oil extraction. Plant tannins make up a distinctive group of high molecular weight phenolic compounds that have the ability to complex strongly with proteins, starch, cellulose and minerals. Chemically three groups of tannins are distinguishable: phlorotannins, hydrolysable and condensed tannins (syn. proanthocyanidins, PAs). In rapeseed (Brassica napus L.) condensed tannins are largely responsible for the dark colour of the seed coat, where they accumulate predominantly in the endothelium cell layer between the outer integument and the aleuronic layer. Whereas the proportion of condensed tannins in the cotyledons of B. napus seeds is comparatively low (0.1-0.5% of dry weight), condensed tannins in dark-seeded B. napus can comprise up to 6% of the seed coat. The objective of this study was to identify quantitative trait loci (QTL) for seed colour, individual and total condensed tannins (syn. proanthocyanidine, PAs) content in a winter rapeseed doubled haploid (DH) population. The plant material consisted of 166 DH lines derived from a cross between an inbred line of the black-seeded German winter oilseed rape cultivar ‘Express’ and the true-breeding, yellow-seeded line ‘1012/98’, both with 00-seed quality. The QTL were mapped using the software PLABQTL based on seed analyses of DH lines grown on field trials in Rauischholzhausen and Gross-Gerau (Germany). Seed colour was measured quantitatively based on digital reflectance values. Individual PAs and total flavonoid content were quantified via HPLC (High Performance Liquid Chromatography) using internal standards for quantification.

Abstract: The experiment was performed on 192 piglets, from weaning (28 days) until they were 106 days of age. At weaning, the piglets were separated in groups according to their body mass; 6 piglets were allocated for each box, (0.40 m2/piglet). The piglets were weighed at weaning, then at 35 days of age, 64 days and 106 of age, in order to calculate the average daily weight gain. Two boxes of piglets were monitored by video recordings the first 72 hours after weaning and 12 hours when they were 106 days old. Then, from the recordings, we measured the time used for resting, eating, moving and displaying aggressive behaviour. Thus, we noticed that the group hierarchy is established within the first    48 hours after group formation. The stress generated by weaning and parting into groups reflected drastically on the weight gain, especially in the first week after weaning (20% of the growth potential), but also until they were 2 months old (approximately 30% of the growth potential). Improving growth potential after weaning can be obtained by avoiding separation into groups of the piglets from different farrowing boxes, or by keeping piglets in the farrowing boxes until they reach 30-35 kilos. Uniformity in weight and numbers of pigs at weaning facilitates economical use of space in the farm. Another, more practical and economical solution is to avoid the stress generated by establishing the hierarchy among piglets in the group, by smell manipulation or tranquilization after separating into lots.

Abstract: The experiment was carried out on 80 reproduction sows within a production cycle. Sow lots were constituted 15 days after artificial insemination. Sows were accommodated in boxes of 10 sows each, which means 2.5 m2 per sow and a foraging front of 40 cm. Between day 15 and day 107 of gestation, sows were weighed weekly to calculate monthly weight gain. Two sow boxes were monitored weekly for 12 hours, in a diurnal regime by video camera recording. We measured and added the times allotted by the sows for resting, moving, feeding, and aggressiveness, and we turned them into recording time shares. Results were correlated with the monthly weight gain in sows and processed to correct technological growth parameters. We could notice that from the first gestation month to the third gestation month resting time increased from 39.82±4.90% to 71.22±3.81% and kept constant until the end of the gestation period. The increase in resting time was compensated by the proportional diminution of the moving time. Sow restricted feeding (2.5 kg mixed feed per day in 2 ratios) resulted in a quasi-constant feeding time during the gestation period. Aggressiveness time diminished from 0.38±0.02% during the first gestation month to 0.06±0.04% in the third gestation month and kept constant until the end of the gestation period.Large individual variations of the time allotted to moving and resting are due to the large differences in weight and age of the sows in the gestation lots. Keeping sows in individual boxes with rigorous control of the amount of feed would allow increased performance of the sows upon farrowing and weaning.

Abstract: Agricultural practices that reduce soil degradation and improve agricultural sustainability are needed particularly for preluvosoil. No-tillage planting causes minimal soil disturbance and combined with crop rotation may hold potential to meet these goals. Soil enzyme activities can provide information on how soil management affects the soil potential to perform processes, such as decomposition and nutrient cycling. Soil enzyme activities (actual and potential dehydrogenase, catalase, acid and alkaline phosphatase) were determined in the 0–20–, 20–40– and 40–60–cm layers of a preluvosoil submitted to a complex tillage (no-till and conventional tillage) and crop rotation (2– and 6–crop rotations)   experiment. Each activity in both non-tilled and conventionally tilled soil under all crops of both rotations decreased with increasing sampling depth. No-till – in comparison with conventional tillage – resulted in significantly higher soil enzymatic activities in the 0–20– and in significantly lower activities in the deeper layers. The soil under maize or wheat was more enzyme-active in the 6– than in the 2–crop rotation. In the 2–crop rotation, higher enzymatic activities were recorded under wheat than under maize. The enzymatic indicators of soil quality were calculated from the values of enzymatic activities determined in the plots of the 6-crop rotation. The results obtained show that the different hierarchies of the six plots as registered in 2008 may be related to the different nature of crops and kind of fertilisers. This means that by determination of enzymatic activities, valuable information can be obtained regarding fertility status of soils.

Abstract: Two hundred and twenty wheat cultivars registered in Hungary in a period of 35 years, from 1970 to 2005, were investigated by molecular markers to determine the frequency of Sr31 and the Sr36 stem rust resistance genes which are very effective in Hungary to date. Among the 156 Hungarian wheats a significant part (32.7%) had the 1RS.1BL wheat-rye chromosome translocation, the source of Sr31 gene, or the Triticum timopheevi introgression with Sr36 gene (17.3%). In the 64 foreign cultivars, deriving from 12 countries, only 4.7% had the 1RS.1BL and 10.9% carried the Sr36. The maximal frequency of cultivars with 1RS.1BL reached 47% (in 1994), and those of with Sr36 reached 32% (in 1983 and 1984). The occurrence of above genes in some wheat cultivars developed and produced in Romania was also investigated. Owning to the threat of new pathogen race Ug99 appeared in Uganda and which is virulent to Sr31 stem rust resistance genes there is an urgent need to incorporate several other Sr resistance genes against into the new wheat cultivars.
