    Mineral oils (such as paraffin oil) have been used for a long time for disease control in vineyards. However the mode of action of this substance have not been studied yet. Our examinations highlighted that paraffin oils do not have a direct fungicide effect against neither the mycelia nor the conidia of Erysiphenecator, the causing agent of powde...

    The technological importance of phenolic compounds, especially flavonoids, is well known. They are responsible for the color of wines, especially anthocyanins (colored pigments responsible for the chromatic characteristics of red wines), proanthocyanidins (responsible for the long term stability of red wine color) and flavonols (compounds that may...

    Superior Seedless is a table grape cultivar mainly produced in San Juan. It has a short productive cycle (120 days) and a long lasting period between harvest and leaf fall (90 days), the consumption in this period is 45% of the total water required. The aim of this work was to develop a regulated deficit irrigation (RDI) strategy during post harve...

    There is some evidence that sugar accumulation is retarded in minimally pruned vines. This may be caused by an excessive yield (i.e. low leaf to fruit ratio) that could affect grape enological quality. Our goal was to evaluate the effect of crop load on grape and wine composition for Cabernet Sauvignon under minimal pruning during two seasons (201...
  • ASSESSING GRAPEVINE BUD FRUITFULNESS FROM DIFFERENT CULTIVARS TO ASSIST EARLY YIELD PREDICTION ÉVALUATION DE LA FERTILITÉ DES BOURGEONS SUR DIFFÉRENTS CÉPAGES POUR LA PRÉDICTION PRÉCOCE DU RENDEMENT

    The number of inflorescence primordia (IP) in compound buds has been previously reported to be closely related to the yield in the coming season. Primary bud necrosis (PBN) is a physiological disorder found in many commercial grapevine cultivars that results in the death of the primary bud and the loss of yield. During winter dormancy, microscopic...

    Vines under minimal pruning reach a balance between vegetative growth and yield. However, berry sugar accumulation may be delayed due to excessive fruit production and this may affect reserves restoration. In this study, we evaluated the influence of the leaf to fruit ratio (LFR) on vegetative growth, yield and reserves accumulation during two sea...
  • RESEARCH ON SAMPLING METHODOLOGIES FOR VINEYARD YIELD FORECASTING IN DIFFERENT CULTIVARS AND TRELLIS SYSTEMS INVESTIGACIÓN DE METODOLOGÍAS DE MUESTREO PARA EL PRONOSTICO DEL RENDIMIENTO DEL VIÑEDO EN DIFERENTES CULTIVARES Y SISTEMAS DE CONDUCCIÓN

    Vineyard yield forecasting is a key issue for vintage scheduling and for optimizing vineyard and winery resources. Errors in yield forecasting are due to high spatial variability present in the vineyard and in some cases to the absence of an adequate sampling method. This project aims to identify the main sources of variability and error in yield ...

    Tolerance to fungi has been the subject of recent programs in France since the 1970s(A. Bouquet, INRA Montpellier). The objective of these programs, initiated from Muscadinia rotundifolia and based on 5 to 6 backcrosses with different Vitis vinifera varieties, was to approach the profile of V. vinifera to be combined with a strong resistance to po...

    In recent years, consumers shifted their interest towards products coming from a viticulture less dependent on chemical inputs also focusing on hybrid varieties. Although information is available in the literature about the attitude of hybrid cultivars in terms of resistance and grape composition, wines made from those varieties are not often been...

    The table grape export business in Argentina had its boom in the last 2000s, when in 2008 it reached a little more than US $ 88,000,000. Since that time, the volume exported has been systematically reduced, which reduced the cultivated area and / or modified its destiny to wine or raisin production. In this context the domestic market of Argentina...

    Spontaneous cover cropping is a common practice in Mediterranean vineyards because it is often seen as less competitive and easier to manage than sown covercrops. However, the services provided by the spontaneous flora highly depend on the species, these latter being influenced by the soil management practices. This study analyzes the specific and...
