Abstract: the use of onion hybrids in brazil is still recent, with little information regarding the gains from heterosis. however, the first step to exploit the heterosis is the evaluation of available germplasm. due to the need for genotypes adapted to the climatic conditions of south-central region of paraná state, brazil, this study aimed to evaluate the agronomic performance of 19 hybrids and 50 inbred lines of onion, as well as the heterotic gain of six of these hybrids. the experimental design was randomized blocks with three replications. the evaluated traits were yield, average weight of the bulbs, commercial classification of bulbs, waxy of the leaves and cycle. in general the hybrids were superior to the lineages in yield and average bulb weight and had lower cycle. the heterotic gain in hybrids was evident, indicating the viability of hybrids for cultivation in the region. hybrids 2572, 2573 and 2578 are promising due their high yield, earliness cycle and better classification of the bulbs. the lineages 2507-1 and 2983 provided the highest heterotic gain for the yield of the hybrid 2857, which was classified in the group of earliest genotypes, showing an inverse correlation between these two characters.

Abstract: the aim of this work was to carry out the chemical characterization and sensory analysis of strawberry fruits from cultivars camp-dover, dover, camp-oso, oso grande, and tudla-milsei, grown in the southern region of minas gerais state. soluble solids, titratable acidity, and the ratio between both characteristics were evaluated, in three replications. sensory analysis was carried out by a panel of 34 non-trained assessors, recruited out of unicentro students, professors, and employees. assessors evaluated the samples for aroma and flavor using sorting-preference tests, with scores from 1 (less preferred) to 5 (most preferred). appearance was assessed by means of a hedonic scale, from 1 (dislike very much) to 9 (like very much). each assessor evaluated five samples of each cultivar for aroma and flavor. to evaluate external appearance, fruits were presented in polystyrene trays, covered with transparent film. cultivars camp-dover, oso grande, and tudla-milsei had the highest (p<0.05) contents of soluble solids (respectively 8.1, 7.8, and 7.6obrix); while for titratable acidity, the highest values were found in fruits of cultivars tudla-milsei, oso grande, and dover (0.88, 0.80, and 0.60). for the soluble solids:titratable acidity ratio, cultivar camp-dover (13.5) significantly exceeded all others. fruits from cultivars camp-dover and oso grande, for their good scores in aroma (3.70 and 2.80, respectively), flavor (3.82 and 3.52), and appearance (7.00 and 7.38) had the best acceptability. considering the results all together, cultivars camp-dover and oso grande stood out as promising options for strawberry growing, since their advantageous fruit characteristics are likely to favor commercialization.

Abstract: several attempts have been made in order to produce garlic out of season in southern brazil, aiming to reduce dependence on imports. the use of cold storage before planting is a possible alternative. another possibility could be forward planting dates using early cultivars, more tolerant to diseases and less demanding in temperature and photoperiod conditions. the objective of the present study was to evaluate the effects of three vernalization periods (30, 40 and 50 days) and three planting dates (23/03, 23/04 and 23/05) on the yield of two garlic cultivars (ca?ador and quitéria). a randomized block design with three replications was used. the assessed traits were plant emergence, plant height, secondary plant growth, total yield and classification of marketable bulbs. the plant emergence and plant height increased in the first cultivation period. the yield of marketable bulbs of the quitéria cultivar increased on the first two planting dates and the ca?ador cultivar showed the highest yield of marketable bulbs on the second planting date. the third planting date provided a decrease in the secondary growth of the ca?ador cultivar plants. the 30-day vernalization period promoted lower secondary growth of quitéria cultivar plants. the 40-day vernalization period, which allowed better adaptation of both cultivars to photoperiod and temperature, resulted in good vegetative and productive development in the region of guarapuava, paraná state, brazil.

Abstract: the garlic behavior and possible variations among cultivars in response to fertilization with sulfur (s), not only in terms of productivity, but also on the characteristics of the bulb and plant development is still unknown. thus, the aim of this study was to evaluate the effects of additional fertilization with elemental sulfur (so) on the bulb yield of three cultivars of garlic, and its effect on several traits of morphology and growth of the bulb and plant. the treatments were arranged in a factorial 3x3, comprising three cultivars (roxo pérola de ca?ador, quitéria and roxo caxiense) and three doses of so (0, 50 and 100 kg ha-1). the experimental design was randomized blocks with three replications. we evaluated the yield; number of leaves; plant height; fresh and dry mass of leaves, pseudostem, bulb and root system; root length; and levels of s and phosphorus (p) on leaves and bulbs. the fertilization with so induced increased yield of the three cultivars, especially the cultivar roxo pérola ca?ador that presented the greatest increase. the increased yield was strongly related to plant vigor, such as height, leaf number and fresh and dry mass of leaves, pseudostem and roots.

Abstract: O presente estudo tem como objetivo veri car a evolu o da percep o dos alunos de Engenharia em rela o às práticas de responsabilidade sócioambiental das empresas. Trata-se de uma pesquisa de naturezaaplicada, quantitativa em fun o do problema, descritiva de acordo com seus objetivos e é um levantamento, considerando os procedimentostécnicos. Utilizou-se um modelo adaptado de questionário do Instituto Ethos (2004), o qual foi pré-testado. Os resultados obtidos mostram que o debate sobre o comportamento ético ou social das empresas ainda é muito pequeno no ambiente acadêmico, e que n o há um crescimento signi cativo no interesse dos alunos em fun o do andamento do curso de gradua o. Com isso pode-se inferir que os futuros engenheirosainda n o est o adequadamente preparados para uma discuss o acerca desta temática. No entanto, veri cou-se que a vis o crítica dos alunos frente às práticas de responsabilidade sócioambiental é melhorada no decorrer do curso de gradua o, facilitando a atua o em situa es do cotidiano. Responsabilidade sócioambiental no Brasil ainda n o é um tema amplamente difundido, mas observou-se que há grande interesse por esta temática, entre os alunos do 1o ano. Dessa forma, pode-seconcluir que este assunto está come ando a ganhar espa o nas discuss esacadêmicas, apontando a probabilidade de um resultado diferente daqui a cinco anos, quando esta nova gera o estará apta para um mercado de trabalho onde as quest es sociais estar o sendo consideradas cada vez mais relevantes.

Abstract: a high incidence of cytomegalovirus (cmv) infections is observed in brazil. these viruses are causatives of significant morbidity and mortality among patients with advanced human immunodeficiency virus (hiv) infection. this work, shows the application of a pcr on determination of cmv load in the buffy coat and plasma. we analyzed the samples of 247 hiv infected patients in order to diagnose cmv infection and disease. we developed a semi-quantitative pcr that amplifies part of the glycoprotein b (gb) gene of cmv. the semi-quantitative pcr was carried out only in positive clinical samples in a qualitative pcr confirmed by a nested-pcr. cd4 lymphocyte count, hiv viral load and cmv disease symptom were correlated with cmv load. cmv genome was detected in the buffy coat of 82 of 237 (34.6%) patients, in 10 of these the cmv load was determined varying between 928 and 332 880 viral copies/mg dna. none of these 237 patients developed any suggestive manifestation of cmv disease. for the other 10 hiv infected patients selected based on the suspicion of cmv disease, cmv genome was detected in only one case. this patient presented a high cmv load, 8 000 000 copies/mg dna, and developed a disseminated form of cmv disease including hepatitis and retinitis. our results were greatly influenced by the impact of the highly active antiretroviral therapy that reduced incidence of cmv viremia and occurrence of cmv disease in the hiv infected patients.

Abstract: Este trabalho objetivou avaliar o efeito da nutri o mineral foliar sobre a incidência e severidade de oídio e ferrugem da soja, bem com a sua influência nos componentes de rendimento e a desfolha da cultura. O delineamento experimental foi em blocos casualizados com cinco repeti es e quatro tratamentos: 1- testemunha; 2- aduba o foliar aos 30 e 60 dias, após a emergência (DAE); 3- fungicida aos 60 DAE; 4- aduba o foliar aos 30 DAE e fungicida + nutrientes aos 60 DAE. Realizaram-se as seguintes avalia es: incidência e severidade de oídio e ferrugem da soja, produtividade, número de sementes por vagem, número de vagens por planta, peso de 100 sementes e porcentagem de desfolha. A aplica o foliar de nutrientes isoladamente n o influenciou na incidência e severidade de oídio, contudo, incrementou a produtividade de gr os. Quando os nutrientes foram aplicados com fungicida, houve redu o tanto na incidência como na severidade das doen as em rela o à aplica o de fungicida isoladamente. A aduba o foliar proporcionou redu o da desfolha e aumento do número de vagens por planta, sendo este último o maior responsável pelo aumento da produtividade. Pode-se concluir que a aduba o foliar potencializou o efeito do fungicida, reduzindo a intensidade das doen as e aumentando a produtividade da cultura. AbstractFungicide application is the main form of soybean crop disease control. However, other measures should be adopted as part of control strategy, such as for example, resistance induction by means of plant mineral nutrition. Therefore, this work aimed to evaluate foliar mineral nutrition effects on incidence and severity of soybean oidium and rust, as well as its influence over yield compounds and culture defoliation. Experimental delineation was in randomized blocks design with five replications and four treatments: 1- witness; 2- foliar fertilization at 30 and 60 days after emergence (DAE); 3- fungicide at 60 DAE; 4- fertilization at 30 DAE and fungicide + nutrients at 60 DAE. Following evaluations were made: soybean oidium and rust incidence and severity, yield, number of seed per pod, number of pod per plant, weight of 100 seeds and defoliation percentage. Isolate foliar nutrient application did not influence oidium incidence and severity in the two evaluation periods, however, it has increased grain productivity. When nutrients were applied with fungicide, there was reduction as much in incidence as in the severity of the diseases in relation to the isolate application of fungicide. Foliar fertilization has proportioned defoliation reduction and incre
