SUMMARYThe period between anthesis and fruit ripening varies according to the Conilon coffee (Coffea canephora) genotype. Therefore, the time of the nutritional requirements for fruit formation may differ, depending on the formation phase and the genotype, and may directly affect split application of fertilizer. The aim of this study was to quantify the accumulation of dry matter and N, P, K, Ca, Mg and S at several stages in the fruit of the Conilon coffee genotype with different ripening cycles, which may suggest the need for split application of fertilizer in coffee. The experiment was carried out in the municipality of Nova Venecia, Espírito Santo, Brazil, throughout the reproductive cycle. The treatments were composed of four coffee genotypes with different ripening cycles. A completely randomised experimental design was used. with five replicates. Plagiotropic branches were harvested from flowering to fruit ripening at 28-day intervals to determine the dry matter of the fruits and the concentration and accumulation of the nutrients they contained. The behavior of dry matter and macronutrient accumulation during the study period was similar and increasing, but it differed among genotypes sampled in the same season. Early genotypes exhibited a higher speed of dry matter and nutrient accumulation. Split application of fertilizer should differ among coffee genotypes with different ripening cycles (early, intermediate, late and very late).Index terms: Coffea canephora, genotypes, maturation cycle, fertilization management.(

-The objective of this work was to evaluate the influence of intercropping 'Conilon' coffee (Coffea canephora) with rubber trees on coffee tree microclimate, nutrition, growth, and yield. Rubber trees were planted in two double rows 33 m apart, with 4x2.3 m spacing between plants. Treatments consisted of the distances from the coffee plants to the rubber trees: 3, 6, 9, 12, and 15 m. Measurements of atmospheric variables (temperature, irradiance, and relative humidity), leaf nutrient concentration, internode length of plagiotropic and orthotropic branches, individual leaf area, chlorophyll content, and yield were performed. Intercropping promotes changes in the microclimatic conditions of coffee plants close to rubber trees, with reduction of temperature and irradiance level and increase in air relative humidity. The proximity of the coffee tree to the rubber trees promotes the elongation of the plagiotropic and orthotropic branches and increases the individual leaf area; however, it does not affect leaf concentrations of N, K, Mg, Fe, Zn, and B in 'Conilon' coffee and does not have a negative impact on yield.Index terms: Coffea canephora, Hevea brasiliensis, irradiance, monoculture, shading. Microclima e desenvolvimento do café 'Conilon' consorciado com seringueiraResumo -O objetivo deste trabalho foi avaliar a influência do consórcio do cafeeiro 'Conilon' (Coffea canephora) com seringueira no microclima, na nutrição, no crescimento e na produtividade do cafeeiro. As seringueiras foram plantadas em duas fileiras duplas, distantes 33 m, no espaçamento de 4x2,3 m entre as plantas. Os tratamentos consistiram das distâncias dos cafeeiros em relação às seringueiras: 3, 6, 9, 12 e 15 m. Foram realizadas medidas das variáveis atmosféricas (temperatura, irradiância e humidade relativa), da concentração foliar dos nutrientes, do comprimento dos entrenós de ramos plagiotrópicos e ortotrópicos, da área foliar individual, da concentração de clorofila e da produtividade. O consórcio promove mudanças nas condições microclimáticas dos cafeeiros próximos da seringueira, tendo ocorrido diminuição da temperatura e da irradiância e aumento da umidade relativa do ar. A proximidade do cafeiro em relação às seringueiras promove alongamento dos ramos plagiotrópicos e ortotrópicos e aumenta a área foliar individual; porém, não afeta as concentrações foliares de N, K, Mg, Fe, Zn e B em café 'Conilon' e não tem impacto negativo na produtividade.

Background. Patients with liver cirrhosis may develop cirrhotic cardiomyopathy (CC), characterized by blunted contractile responsiveness to stress, diastolic dysfunction (DD), and electrophysiological abnormalities. It may adversely affect the long-term prognosis of these patients. Methods. We conducted a retrospective analysis of patients undergoing liver transplantation (LT) for cirrhosis from January 2012 to June 2015. We analyzed demographic characteristics, the etiology of cirrhosis, Child-Pugh and Model for End-Stage Liver Disease (MELD) scores, the corrected QT (QTc) interval in the preoperative period, diastolic and systolic dysfunction, mortality and survival, and duration of mechanical ventilation and vasopressor support in the post-LT period. These variables were compared with diastolic dysfunction and prolongation of QTc, with the use of chisquare, Fisher, and Mann-Whitney U tests. Results. The study included 106 patients, 80.2% male and overall average age 54.83 years. The median MELD score was 16, and Child-Pugh class C in 55.4%. Prolonged QTc interval before LT was present in 19% and DD in 35.8% of patients. QTc before LT or DD did not vary significantly with MELD or Child-Pugh score. Conclusions. The patients in the pre-LT period presented with a significant incidence of DD, which can predispose them to adverse cardiac events. The presence of DD correlates with mortality after LT in patients with hepatic cirrhosis.

The seasonal pattern of vegetative growth is an important feature for evaluation of crop status and its management. The aim of this work was to evaluate the seasonality of vegetative growth of Conilon coffee tree (Coffea canephora Pierre) and its relation with climate variables. The evaluation of vegetative growth rates of three groups of plagiotropic branches and one group of orthotropic branches was performed along one year, in Rio Janeiro state, Brazil. The vegetative growth rates of the branches varied along the period of evaluation, and it seems to be related to the minimum air temperature (in the low growth phase). Higher growth rates were observed when the average of minimum air temperatures was higher than 17ºC and the average of the maximum temperatures lower than 31.5ºC. Below 17ºC the growth rate declined. The branches' growth patterns appeared to be similar, but the plagiotropic branches of different ages presented different rates in the same period of the year, indicating that seasonal growth studies should not be based on a single branch group with the same age. Key words: Coffea canephora, air temperature, stress ResumoO padrão do crescimento sazonal do cafeeiro é um importante auxiliar na avaliação do estado fisiológico e no manejo da cultura. O objetivo do estudo foi avaliar o crescimento vegetativo em Coffea canephora Pierre cv. Conilon e relacionar com fatores climáticos, tendo por base o crescimento de ramos ortotrópicos e plagiotrópicos com diferentes idades. Marcaram-se três grupos de ramos plagiotrópicos e um de ramos ortotrópicos, cuja avaliação de taxa de crescimento foi efetuada durante um ano no Estado do Rio de Janeiro. A taxa de crescimento varia ao longo do ano, o que parece estar relacionado com a temperatura mínima do ar (na fase de baixo crescimento). Foi observada taxa mais elevada quando a média da temperatura mínima do ar foi superior a 17ºC e a média das temperaturas máximas inferior a 31,5ºC. Abaixo de 17ºC a taxa de crescimento dos ramos diminuiu. O padrão sazonal de crescimento dos ramos é semelhante, contudo, os ramos plagiotrópicos de diferentes idades apresentam taxas de crescimento diferentes no mesmo período do ano. Assim, estudos sobre o crescimento vegetativo sazonal dos ramos não deve se basear apenas num grupo de ramos com idades similares.

-The aim of this study was to assess the effect of different coatings on the physiological potential of stylosanthes cv. Campo Grande seeds. The treatments were: uncoated seeds; limestone + PVA glue; limestone + sand + PVA glue; limestone + activated carbon + PVA glue; calcium silicate + PVA glue; calcium silicate + sand + PVA glue; calcium silicate + activated carbon + PVA glue. Posteriorly, the seeds were analyzed for water content (WC), maximum diameter (MAD) and minimum diameter (MID), thousand seed weight (TSW), germination test, germination speed index (GSI), mean germination time (MGT), emergence, emergence speed index (ESI), mean emergence time (MET), shoot and root length, fresh and dry matter of shoot and root. The coating increased the TSW, MAD and MID and decreased its WC. The treatments comprising limestone + PVA glue and limestone + sand + PVA glue increased the germination time, but none of the treatments negatively affected the physiological seed quality. Treatment with calcium silicate + PVA glue was outstanding for germination speed index and fresh and dry matter of shoot and root in the stylosanthes cv. Campo Grande seeds coating.

RESUMOA cultura do feijoeiro tem grande importância para o Estado de Goiás, Brasil. No entanto, informações relacionadas aos padrões nutricionais para condições irrigadas são carentes na região. Os objetivos deste trabalho foram estabelecer padrões foliares, avaliar o estado nutricional do feijoeiro irrigado na região do Vale do Rio dos Bois, no Estado de Goiás, pelos métodos da faixa de suficiência (FS), da diagnose da composição nutricional (CND) e do sistema integrado de diagnose e recomendação (DRIS), bem como comparar os procedimentos de diagnóstico por meio de padrões nutricionais locais. Avaliaram-se a produtividade e a concentração foliar de 55 lavouras de feijoeiro na região do Vale do Rio dos Bois, entre 2010 e 2012. As amostras foram coletadas no estádio R5 (período de floração) e analisadas quanto aos teores totais de N, P, K, Ca, Mg, S, B, Cu, Fe, Mn e Zn. As 55 amostras foram divididas em dois grupos, sendo o primeiro de baixa produtividade, com rendimento abaixo de 2.700 kg ha -1 ; e o segundo de alta produtividade, com rendimento igual ou acima de 2.700 kg ha -1 , este último originando os padrões nutricionais. Normas CND e DRIS são mais indicadas para avaliação nutricional do feijoeiro irrigado comparativamente a FS estimada neste trabalho. Manganês, P e B são os elementos que mais limitam a produção nas lavouras de baixa produtividade na região do Vale do Rio dos Bois.Termos de indexação: análise foliar, diagnose foliar, nutrientes, Phaseolus vulgaris.
