AIM: The increase in the temperature and the more severe water stress conditions, trends observed in recent years as a consequence of climate change, are leading a mismatch between the technological and phenolic maturity of grapes [1]. As a strategy to face this situation, the use of apatite (Ap) nanoparticles as nano-transporters of the elicitor, […]
AIM. Cultivation of a few number of clones is causing the loss of vineyard biodiversity, resulting in the disappearance of biotypes that could be of interest to face future challenges, such as climate change or appearance of new pests. This topic is so relevant that OIV dedicated a recent resolution (OIV, 2019) to the recovery […]
AIM: The grape volatile compounds determine the wine quality and typicity [1]. Thus, looking for agronomic tools to improve its composition it is of great interest in the sector [2]. The aim of this work was to study the effects of several foliar applications in Garnacha, Tempranillo, and Graciano grapevines in order to enhance their […]
AIM: The production of grapes with a balanced composition is one of the main goals that agronomists and oenologists pursue to produce premium quality wines. The gap between technological (sugar/acid ratio) and aromatic maturity is expanding due to the increasing temperature and lack of rainfall during the ripening phase. In three consecutive years 2017, 2018 […]
AIM: the aim of this study was to develop a method for fine-scale temperature zoning. The effect of temperature variability on vine phenology and grape composition was assessed in the production area of Saint-Emilion, Pomerol and their satellite appellations (Bordeaux, France). METHODS: 90 temperature sensors were set up inside the vine canopy over an area […]
