Abstract The decrease of variability sources and the genotypes instability as a result of climate changes from the last years were issues addressed in the breeding programs. For breeders the stability of some parameters like plant height is very important in selection process, therefore the influence of climatic variations it is aimed to be reduced by genetic response of the genotypes. Semi-dwarf genotypes are preferred by breeders because in this way is avoided the lodging risk. A set of 307 mutant and mutant/recombinant wheat DH lines, along with parental genotypes, was analyzed in three different years for plant height and the semi-dwarf selected lines were evaluated for stability of this parameter. The material was also analyzed for the presence of Lr34, or genes and 1A/1R translocation. In our study the reduced plant height and its stability was not associated with any of the genetic background

Abstract The lungworm Aelurostrongylus abstrusus (Nematoda: Angiostrongylidae) is a parasite of domestic and wild felids with worldwide distribution. The parasite lives in bronchioles and alveolar ducts, and its presence is associated with respiratory clinical signs. Cat lungworms are still considered by many clinicians sporadic and rarely are taken into account in the cat pathology. Therefore, in this paper we present a clinical and epidemiological study on cats with natural A. abstrusus infection. For this, 131 cats, with exclusive outdoor or outdoor and indoor access, of different gender (49 males, 82 females) and age (between 2 months and 11 years), from Southern and Center Romania, were included in the study. Of them, individual fresh faecal samples were collected and analyzed to identify first-stage larvae (L1) of lungworms, using a Baermann technique, and eggs/oocysts of other endoparasites, by a flotation method. Subsequently, of the examined samples, 6.10% (8/131) were positive for A. abstrusus. The positive cats aged between 3 months and 2 years. Of them, 3 cats were co-infected: two with Toxocara cati and one with Ancylostoma tubaeforme. Clinically, 75% (6/8) of the infected cats displayed respiratory signs varying from mild (sporadic coughing, sneezing) (n=3) to severe symptoms (mucopurulent nasal discharge, abdominal breathing) (n=3), while 25% (2/8) showed no respiratory signs. The three cats with severe respiratory disease were infected only with A.abstrusus. In conclusion, veterinary practitioners should include Aelurostrongylus infection in the differential diagnosis of catʼs respiratory pathology.

Abstract Broad scale use of chemical pesticides is known to have produced broad scale environmental impact worldwide and, at the same time, discovery and registration of new molecules to be used as insecticides, herbicides and fungicides have slowed significantly along the last decades, reducing the number of options for pest control by the farmers. Searches for novel environmentally friendly products are a recognized priority. In this work, aqueous solutions of chitosan oligomers (COs) and propolis (P), individually or as binary mixtures, were tested against Hemileia vastatrix, the fungus which causes coffee leaf rust, the worst disease of coffee. Germination of H. vastatrix was inhibited up toll 99 % by COs, followed by the mixture of COs-P and P individually (germination inhibition of 96 % and 54 % respectively). Testing those products on detached coffee leaf discs also produced promising results when COs were applied before H. vastatrix inoculation. These results may lead to the discovery of new antifungal products for the control of coffee leaf rust.

Abstract The experiment was carried out on four groups of Hy-Line var. Brown hens (n = 350 each) fed on diets which provided 2.49, 3.07, 3.78 and, respectively, 4.15 g% calcium (Ca) during the laying period. Consequently, mean daily Ca intake was 2.74, 3.38, 4.16 and 4.60 g/cap., respectively. Ca metabolism was assayed at 20 weeks of age (start of the laying), 36 weeks of age (the peak of the laying) and 68 weeks (the end of the laying period). A significant part of the ingested Ca was not absorbed. The percentage of Ca exonerated by feces was higher at the start of the laying and lowers in the peak of laying and at the end of the laying period. The amount of Ca exonerated as unabsorbed Ca increases as the amount of ingested Ca increases inside of each age level. It was found also an increase of the Ca content of the egg shell according the Ca intake statistically significant (P<0.05) in 36- and 68-wk.-old hens, but not in 20-wk.-old hens. Blood plasma Ca showed significantly higher values in 3.38-, 4.16- and 4.60-g/day-Ca-intake groups when compared by 2.74-g/day-Ca-intake group (P < 0.05) but the level of increasing showed lowest values in hen groups with highest intake of Ca. The daily eggshell Ca export strongly correlates with the amount of daily Ca intake in 36-wk.-old hens and 68-wk.-old hens: r = +0.72 and +0.84, respectively, but no correlation was found in 20-wk.-old hens (r = -0.74, negative correlation). The results showed a limited physiologic capacity of the Ca absorption in hen, the Ca surplus being lost. Dietary Ca level should be closely correlated with the laying level of hens.

Abstract Canine mesenchymal stem cells (MSCs) can be defined with self renew potential and specific differentiation capacity. Amiotic membrane represent an important source of MSCs, which can be harvested by minimally invasive methods. The aim of our study was to evaluate the growth characteristics of canine amniotic membrane derived mesenchymal stem cells. The placenta samples were collected after cesarean section from healthy mixed breed dogs. MSCs isolation was performed using enzymatic method. Isolated cells were cultured in propagation medium: Dulbecco’s Modified Eagle’s Medium/F12 (DMEM/F12, Gibco) supplemented with 10% fetal bovine serum (FBS, Gibco) and 1% antibiotic-antimycotic (Sigma-Aldrich). The medium was changed after 4 days. The cell doubling number, cell proliferation capacity, cell doubling time, daily duplication rate and clonogenic efficacy were evaluated. Our study demonstrate the self renew potential of canine amniotic membrane derived mesenchymal stem cells, and can represent a potential source of stem cells for canine regenerative medicine.

Abstract Grafting berries is a topic untouched by researchers or practitioners till now in Romania due to the convenient and widely spread way of classic propagation methods. Nevertheless, the positive effect of grafted plants in commercial orchards is well known at many other species. Traits like precocity, uniformity, fruit size and yield stability is desired to be achieved in this manner. By grafting berries, we look forward to eliminate the actual shortcomings of the traditional crop systems, mainly generated by bushy crown shape that requires large distance between the plants, difficulties in mowing or weeding process along the rows, pruning and harvest operation in a uncomfortable arch position, discontinuous application of pesticides inside the bush etc. In this regard, different methods and trials have been conducted in the last two years at the University of Agronomic Sciences and Veterinary Medicine Bucharest in order to eliminate these bottlenecks in the berry technology trough grafted plants.

Abstract Due to technological advances in bio-imaging in the last years, magnetic resonance imaging (MRI) is widely used as a noninvasive and non-irradiant tool for assessment and imaging diagnosis. In this study are presented two dogs with progressive clinical and neurological manifestations, following the discovered signs (head tilt and circling in the first case, respective epileptic seizures and ataxia in the second case), MRI evaluation was recommended. The imaging exams showed the presence of a mass, located in the third ventricle, with heterogeneous signal changes in conventional sequences T1, T2 and FLAIR. Unifying the imaging data with those of the histopathological examination it was possible to establish the diagnosis of choroid plexus carcinoma in both cases.

Abstract The paper was based on the idea that important changes have been occurred in the last years in the Romanian agriculture. Labour is one of the most important production factor in rural area and when this is linked to the agriculture sector, becomes a strategic issue. Land as one of the most limited resources in agriculture plays also an important role, its degree of concentration determining the structure of the farms system. The purpose of the study was to explore, by means of the Gini coefficient, whether the labour, in different forms (paid, unpaid labour) follows a similar degree of concentration as the Total Utilized Agricultural Area (UAA) and the farm output. The datasets used for the paper were the FADN public database (period 2007-2015) and the Tempo online dataset from Romanian National Institute of Statistics. The findings of this analyse were that paid labour, unpaid labour and the output followed a decreased trend of concentration and become during the analysed period, more equal distributed, while the area tends to have more unequal distribution, so the large farms tends to become larger.

Abstract Recent research reports that enzymes accumulated in soil participate in the cycles of elements and contribute to soil fertility. The purpose of this paper is to determine the enzymatic activity and the humus content in the materials from waste heap in order to assess their fertility and to establish possible re-cultivation technologies. The investigations were carried out on materials from the Pesteana North waste heap. In order to achieve this, the activity of catalase, invertase, urease and phosphatase activity was determined in different plots of the heap during the summer and as a control the zonal soil was used. Enzymatic activities were colorimetric assay using appropriate substrates. The obtained results show a large variation in the values of the determined enzymatic activities. In all investigated plots, all enzymes are found to be lower than those determined for the zonal soil. A strong positive correlation is observed between enzymatic activities of catalase and invertase and the accumulation of humus which demonstrates that enzymatic activities has a useful tool for studying the evolution of heap materials to agricultural soils.

In order to achieve this, the activity of catalase, invertase, urease and phosphatase activity was determined in different plots of the heap during the summer and as a control the zonal soil was used. Enzymatic activities were colorimetric assay using appropriate substrates. The obtained results show a large variation in the values of the determined enzymatic activities. In all investigated plots, all enzymes are found to be lower than those determined for the zonal soil. A strong positive correlation is observed between enzymatic activities of catalase and invertase and the accumulation of humus which demonstrates that enzymatic activities has a useful tool for studying the evolution of heap materials to agricultural soils.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"77 1","pages":"367 - 372"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89116972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
