| Abstract: Goat farming is a very important activity contributing to the social and economic development of northeastern (NE) Brazil. The objective of the present study was to characterize the goat farming production system in five of the nine states that constitute the Brazilian NE (Ceará, Paraíba, Piauí, Rio Grande do Norte, and Sergipe). Research was carried out in 230 rural properties located in 62 municipalities of the NE of Brazil, in regions exhibiting a productive arrangement and significant goat population density. An epidemiological questionnaire seeking information on economic, productive, and social aspects of owners/properties was supplied to all properties. The results described the goat farming system in the Brazilian NE as family and... |

| The objective of this work was to evaluate the influence of different combinations of grape cultivars and rootstocks on chemical characteristics of grape juices. Six treatments were evaluated, consisting of combinations between the Isabel Precoce and BRS Cora grape cultivars and the 'IAC 766', 'IAC 313', and 'IAC 572' rootstocks. Approximately 10 L of juice were obtained per treatment. Analyses of color, total soluble solids content, pH, anthocyanins, total phenolics, total sugars, and quantification and identification of biogenic amines by HPLC were performed. Biogenic amines, such as putrescine, cadaverine, spermidine, and spermine, were found in all evaluated cultivars. By principal component analysis (PCA), treatments can be divided into two groups,... |

| Objetivou-se avaliar a incidência de ferrugem em mudas de genótipos cafeeiros, provenientes do Banco de Germoplasma de Minas Gerais, quando submetidas a inoculação natural. Foram utilizadas oito progênies e duas cultivares de café. As mudas foram produzidas em viveiro e posteriormente transferidas para casa de vegetação com umidade e temperatura controladas. Após um mês de aclimatação, as mudas foram submetidas à presença de plantas contaminadas com o fungo Hemileia vastatrix (inoculação natural). A incidência de ferrugem foi avaliada em cada muda, com cinco avaliações em intervalos de sete dias, sendo a primeira avaliação realizada após o aparecimento dos primeiros sintomas, a fim de quantificar as folhas infectadas e não infectadas. Foram realizados a... |
