The estimation of the clear-sky effective PAR resources in a mountain area

Due to the central role of the ripening timing in the evaluation of the varietal response to the environmental resources, a method to manage maturation curves has been developed. The method produces an index of veraison precocity and overcomes several methodological problems, like the visual evaluation of the veraison point and the multi-annual and multi-varieties data processing. It is based on a statistical and mathematical processing of the sugar ripening curves.

In a context of a sustainable viticulture, a new uprising strategy to improve grape and wine composition (or quality) is the exogenous application of plant activators(Gil-Muñoz et al., 2017)

This study examines the different strategies adopted by wine exporters located in France for penetrating international alcohol distribution networks in the U.S. market (and to a lesser extent the Canadian market). Grounded in the Business-to-Business (B2B) marketing literature (Ellegaard and Medlin, 2018), this study adopts a framework integrating a ‘Stakeholder’ approach for understanding the logics behind exporters’ strategies to penetrate the alcohol distribution networks (wholesalers, importers, alcohol monopolies).

Context and purpose of the study ‐ Vine balance is a concept describing the relationship between carbon assimilation (usually estimated using a measure of vine vigour, e.g. pruning weight) and its utilisation for fruit production (usually estimated using harvest yield). Manipulating vine balance through leaf area or crop load adjustments affects the proportion of the vine’s total carbohydrate production required to mature the fruit. It is commonly considered that composition of the berry, and resulting wine, is strongly affected by vine balance.
