| Abstract The aim of this study focused on the construction of the absorption and extraction curves under an aeroponic system for White chrysanthemum cv. Atlantis White, and therefore, propose the periods of maximum and minimum nutrient accumulation from aboveground, root and total biomass. Vegetative cycle of the plant, measured from the day after transplantation (dat) to aeroponic system, and the first day of court lasted 49 days. Evaluations were carried out each week on plants, in absolute competition. For the average aboveground biomass, three replicates were recorded. To obtain total root biomass only one sample, was measured. Therefore, total biomass in average, had achieved 130.9313 g.plant-1, where 72.26% (94.163 g) corresponded to the aboveground... |

| The objective of this work was to assess the performance of panel clones under crowns resistant to South American leaf blight (Microcyclus ulei). The experiment was carried out with 18 panel clones crown-budded with Hevea pauciflora x H. guianensis, in a Xanthic Ferralsol (Oxisol) in Manaus, AM, Brazil. The following parameters were evaluated: dry rubber yield, plant nutritional status, and anatomical and physiological characteristics of the latex vessels. In the first three years of evaluation, the panel clones IAN 2878, IAN 2903, CNS AM 7905, CNS AM 7905 P1, and PB 28/59 showed the highest dry rubber yield potential, while the clones IAN 6158, IAN 6590, and IAN 6515 should not be recommended for crown budding. Higher potassium and copper foliar content... |

| The ideal feeding for premature babies has been the source of extensive debate. The aim of this study was to assess the association between type of feeding at discharge and the nutritional status of very low birth weight infants. This was a retrospective cohort of preterm babies with birth weight ≤1500 g, born between January 2006 and December 2013. The infants were divided into 3 groups according to type of feeding at discharge: exclusive breast milk (group 1), mixed feeding (group 2) and exclusive artificial formula (group 3). Frequencies of each group were calculated, as well as mean Z-score differences in weight, length and head circumference. Six hundred and forty-nine newborns were included. The mean weight of groups 1, 2, and 3 was 1338.7, 1104.0,... |

| O experimento foi conduzido no Departamento de Ciência do Solo da Universidade Federal de Lavras ? UFLA, no período de junho a agosto de 2002. Objetivou-se avaliar a produtividade, o estado nutricional e a qualidade (classe de tamanho) de cultivares de alface cultivadas com doses de silicato de cálcio em vasos sob casa-de-vegetação. O delineamento experimental foi em blocos casualizados, com quatro repetições, com 1 planta/vaso, em esquema fatorial 3 x 4 + 3, sendo três cultivares de alface (Raider, Regina e Vera) e quatro doses de silicato de cálcio (0, 410, 1,000 e 2,000 mg dm-3); os tratamentos adicionais foram compostos pela aplicação de 820 mg dm-3 de carbonato de cálcio, para as três cultivares. O estado nutricional das plantas de alface foi avaliado... |

| O presente trabalho objetivou avaliar o efeito de fungos micorrízicos arbusculares (FMAs) na nutrição de mudas de acácia (Acacia mangium Willd.), sesbânia (Sesbania virgata (Cav.) Pers.) e eucalipto (Eucalyptus camaldulensis Dehnh.) em casa-de-vegetação, bem como a influência dos FMAs, do monocultivo e/ou consórcio sobre os teores dos nutrientes nas folhas das plantas em cava degradada pela extração de argila. Em casa-de-vegetação, mudas de acácia inoculadas com FMAs tiveram incrementos nos conteúdos de N, P e Zn de 22, 71 e 67%, respectivamente; as de sesbânia, de 39, 49, 56, 24, 105 e 54%, respectivamente para N, P, Ca, Mg, Mn e Zn. Na cava de extração de argila, plantas de acácia consorciadas com sesbânia apresentaram menor teor de Ca nas folhas. Ainda,... |

| Shrimp aquaculture in New Caledonia is subject to seasonal mortalities during grow-out due to highly virulent Vibrio nigripulchritudo (Vn). To understand the mechanisms affecting shrimp resistance and leading to significant mortality, a shrimp ecophysiology and immunology survey was conducted on two farms, the first considered as a "control" farm (HC), the second affected by the disease (DF). Mortality observed during the survey at DF started 50 days after stocking and was typical of this disease. The main observations regarding shrimp were: (a) growth was not affected by the disease and was faster in the DF than in the HC pond; (b) disease did not affect one sex more than the other, or a specific part of the population in terms of weight; (c) the physical... |

| ABSTRACT This study aimed to evaluate the fertiliser sources and application methods of copper (Cu) in citrus trees during the first years of fruit production. Two experiments were set up in an orchard with 3-year-old sweet orange trees, which were applied with three sources of Cu (nitrate, sulfate or EDTA) either via fertigation (Experiment 1) or via foliar sprays (Experiment 2). Regardless of the fertiliser source, Cu application via fertigation was not efficacious to increase the micronutrient concentration in leaves and, consequently, did not affect fruit yield. Conversely, foliar application of Cu, either as nitrate or sulfate, increased this nutrient level in leaves but when applied as copper nitrate, visual phytotoxicity symptoms were verified in... |

| Foram avaliadas quatro posições de amostragem de folhas de pimenta longa para fins de definição da amostragem mais adequados em estudos de nutrição de plantas desta espécie, visando subsidiar pesquisas com sua domesticação. Folhas completamente expandidas de vinte plantas de diferentes parcelas experimentais de um experimento, que receberam mesma adubação anual, foram amostradas, nas posições, do ápice para a base do galho: P1- primeira folha, P2 – segunda folha, P3 - terceira folha e P4, quarta folha, tomando-se, vinte amostras por parcela, as quais foram depois reunidas em uma amostra composta por parcela As folhas foram avaliadas para os teores de macro e micronutrientes. Foram comparadas médias e variabilidade entre as diferentes posições, com base nos... |
