| Desde 2001 se observan en viñedos de Córdoba, Argentina, hojas de Vitis vinifera y V. labrusca con manchas cloróticas y centro necrótico. Las plantas presentan nervaduras, pecíolos, raquis y entrenudos con puntos necróticos que al confluir agrietan el tejido cortical. Las bayas pueden marchitarse y desprenderse. En invierno los sarmientos toman color blanquecino con manchas negras, y en ellos y en órganos secos aparecen picnidios con cirros blanco-crema con conidios alfa y beta. El objetivo fue confirmar la presencia de Phomopsis viticola (excoriosis) y cuantificar su incidencia. Se realizaron aislamientos a partir de pecíolos, brotes, zarcillos, bayas y sarmientos que produjeron micelio claro con picnidios y conidios alfa (7,5m±1,5 x 2,8m±2) y beta (19m±1... |

| La comparación entre sistemas micrometeorológicos permite analizar la confiabilidad de los resultados y evaluar su ajuste a diferentes cultivos. En el presente estudio se midió la evapotranspiración (ET) de una cubierta de viña (Vitis vinifera) en espaldera, durante su ciclo de crecimiento anual, mediante los métodos micrometeorológicos razón de Bowen (BREB) y covarianza de torbellinos (EC). La investigación se realizó en el 2007 en la localidad semiárida de Tarazona de La Mancha, España. El principal criterio de comparación entre los sistemas fue el valor diario y acumulado de la ET actual. Una vez forzado el cierre de energía, el sistema BREB sobreestimó los flujos del sistema EC en valores promedio de 5 %. Las diferencias se pueden explicar por la... |

| Argentinean Vitis vinifera cultivars although originated from Europe, have clear ampelographic and genotypic differences as compared with the European cultivars currently used in wine making. In vitro evaluation of salt tolerance has been used in many species. Our hypothesis was that Argentinean cultivars are more tolerant to salinity than European ones. Three European cultivars, Malbec, Cabernet Sauvignon and Chardonnay and four Argentinean cultivars, Cereza, Criolla Chica, Pedro Gimenez and Torrontes Riojano were tested by in vitro culture. Treatments included: 1) Control, 2) 60 mEq/L of a mixture of three parts of NaCl and one part of CaCl2 and 3) 90 mEq/L of the salt mixture. Results from two experiments (I and II) are reported. No differences were... |

| The performance of Syrah grapevine under protected cultivation with different plastic films was evaluated during 2012 and 2013 seasons in South of Minas Gerais State. Agronomical and physiological measurements were done on eight years old grapevines, grafted onto ‘1103 Paulsen’ rootstock cultivated under uncovered conditions, covered with transparent and with diffuse plastic films. Both plastic covers induced the highest shoot growth rate and specific leaf area. The diffuse plastic induced greater differences on leaf area, pruning weight and leaf chlorophyll content as compared to uncovered vines. Grapevines under diffuse plastic also had the lowest rates of photosynthesis, stomatal conductance and transpiration. Leaf starch, glucose and fructose contents... |

| The control of leaf to fruit ratio by the practice of entire clusters removal from the vine upon berry set has been used in traditional vineyards in order to regulate yield and to improve chemical composition of the berries. Although this practice has been settled in temperate zones, little is known about grapevines behavior in tropical growing areas. The aim of this work was to evaluate the biochemical and agronomical responses of two Vitis vinifera cultivars (Merlot and Cabernet Sauvignon) grown in Caldas, Minas Gerais, Brazil, a new winegrape region. Grapevines were submitted to cluster thinning (0%, 50% and 75% of cluster removal) and trimming treatments (trimmed and untrimmed) imposed at pea size stage. The source-sink alteration by fruit removal and... |

| ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and east/west face), at veraison, and a group without defoliation, were compared in order to observe the impacts of this management on the productivity, grape and base wine quality. Yield, grape components, must and base wine composition were analyzed for two years. East/west defoliation increased alcohol content and decreased acidity in base wines, while the group without defoliation increased acidity,... |

| ABSTRACT The agronomical responses of Chardonnay, a variety indicated for sparkling wine production, is influenced by the vineyard management and the edaphoclimatic conditions of the region. The objective of this study was to evaluate the effects of two pruning types (Royat and double Guyot) on vegetative and reproductive development of Chardonnay vine growing at high altitude in the Brazilian southeastern region. The experiment was carried out in a commercial vineyard located at 1,280 m of altitude in Divinolândia, São Paulo State, Brazil. The Chardonnay vines (clone 96), grafted onto 1103 Paulsen rootstock and trained in a vertical shoot positioning trellis system, were assessed. Vegetative vigor, bud fruitfulness, production and physicochemical... |

| A mosca-das-frutas sul-americana, Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae), é uma das principais pragas da fruticultura no Brasil. O objetivo deste estudo foi identificar a suscetibilidade quanto à queda e deformação de bagas de diferentes cultivares/espécies de uva pela injúria causada pela oviposição de A. fraterculus. O trabalho foi realizado em vinhedos das cultivares 'Cabernet Sauvignon' (Vitis vinifera), 'Moscato Embrapa' (75% de V. vinifera) e 'Isabel' (Vitis labrusca), localizados em Bento Gonçalves (RS), na safra 2006/2007. Dois casais de A. fraterculus foram confinados por cacho, em gaiolas de tecido voile, durante os estádios fenológicos de grão ervilha, início da compactação, início da maturação e maturação plena dos cachos.... |

| Vários trabalhos descrevem a época ou o estádio fenológico em que ocorre a formação de primórdios de inflorescência em gemas de videiras. No entanto, os relatos são bastantes diversos sobre esse assunto, possivelmente, devido às diferenças de condições climáticas entre as regiões produtoras. Neste contexto, foi desenvolvido um experimento no período de agosto de 2002 a fevereiro de 2003, com o objetivo de determinar como ocorre a formação de gemas férteis em videiras cv. Itália, nas regiões de Jales e Jundiaí (SP). A cada período de 15 dias após o início da brotação, foram amostrados cinco ramos de cada vinhedo para as avaliações. Até o 15.º nó de cada ramo, as gemas foram dissecadas e examinadas sob estéreo microscópio quanto à presença de primórdios de... |

| Winegrape productivity and quality has been related to the regulated deficit irrigation, with important implications for the plant bioenergetics. When water deficit is imposed to grapevine plants, alterations in overall photosynthesis and cell respiration are observed. The aim of this study was to assess the modulations promoted by water stress on photosynthesis and respiration in leaves of the cv. Cabernet Sauvignon (cv. CS) for better understanding the physiological responses related to its drought tolerance and quality improvement under water deficit. For this purpose, measurements of photosynthetic efficiency, leaf water potential, gas exchange and O2 consumption were carried out. Leaf water potential, photosynthesis, stomatal conductance,... |

| Early light induced proteins (ELIP) are a type of proteins which are expressed before than other chloroplast proteins in the presence of light. These proteins have been studied in a large number of annual species such as pea (Pisum sativum L.), barley (Hordeum vulgare L.) and Arabidopsis sp. In perennials plants the studies about ELIPs are very scarce. The possible photoprotective function of the ELIPs has motivated the interest in investigating the presence of this type of proteins in a perennial plant such as grapevine (Vitis vinifera L.) and if their characteristics differ from those found in annual plants. In this paper a comparative study was conducted on the ELIPs expression in grapevine and pea to investigate whether there are differences regarding... |
