Presentation
In different disciplines, visible and near infrared spectroscopy (VIS-NIR) is increasingly used for in-line and handheld applications. There is a risk that abnormal observations may occur. It is then important to handle correctly the outliers to develop effective prediction models. The objective of this study is to examine the potential of a robust...
Article
Visible and near infrared spectroscopy (VIS-NIR) is increasingly being transferred from laboratory to industry for in-line and portable applications in various domains. By intensively using VIS-NIR spectroscopy, some abnormal observations may certainly arise. It is then important to properly handle outliers to elaborate effective prediction models....
Article
Hyperspectral imaging is an emergent technique in viticulture that can potentially detect bacterial diseases in a non-destructive manner. However, the main problem is to handle the substantial amount of information obtained from this type of data, for which reliable data analysis tools are necessary. In this work, a combination of multivariate curv...

Temperature is a key environmental factor affecting grape primary and secondary metabolites. Even if several mesoscale studies have already been conducted on temperature especially within a Protected Designation of Origin area, few data are available at an intra-block scale. The present study aimed at i) assessing the variability in bunch zone air...

Since the early 1990s, grapevine trunk diseases (GTDs) have posed threats for viticulture. Esca complex, Eutypa- and Botryosphaeria- diebacks, mostly detected in adult vineyards, are currently responsible for considerable economic losses in the main vine-growing areas of the world. Other GTDs, such as Petri- (Esca complex) and Black-foot diseases,...

The main objectives of this study was to decrease wine alcohol content by combining several techniques, from the vineyard to the cellar. The combination of these techniques should allow to decrease alcohol in wine by 2% in volume. A two years trial was focused on two main cultivars of the southwest of France vineyard: Tannat N and Gros Manseng B. B...

Mediante los conservatorios de variedades y la colaboración ciudadana se han identificado más de un centenar de variedades minoritarias procedentes de las regiones que rodean los Pirineos. Con 78 de dichas variedades identificadas se han realizado más de 200 microvinificaciones que han permitido, por una parte, evaluar su potencial enológico y, por...

Grapevine trunk diseases (GTD) involve several fungal diseases and numerous fungal species that induce wood deterioration and lead to reduced yield and grape quality. Common and innovative control practices that winegrowers have recognized as eficient in overall GTD management were identiied and collected within WINETWORK project. In order to answe...

Project WINETWORK is developing the innovation-driven methodology, which promotes the exchange of knowledge between science and practice. This network is implemented in ten winegrowing regions, within seven European countries. The methodology is built on a network of winegrowers and regional experts gathered in regional Technical Working Groups, Sc...
