Use of the stics crop model as a tool to inform vineyard zonages

Abstract

[English version below]

STICS est un modèle de culture développé à l’INRA (France) depuis 1996. Il simule les bilans de carbone, d’eau et d’azote dans le système culture-sol, piloté par des données climatiques journaliéres. Il calcule à la fois des variables agricoles (rendement en quantité et qualité) et environnementales (pertes en eau et en azote). Une des originalités de STICS est son adaptabilité à de nombreuses cultures (herbacées, ligneuses, annuelles, pérennes) rendue possible par le choix de paramètres génériques et d’options de formalismes. Le travail présenté traite, dans un premier temps, des spécificités de STICS pour la vigne en terme de bilan trophique, de fonctionnement énergétique et hydrique et d’estimation des teneurs en sucre en en eau du raisin. Nous montrons ensuite diverses sorties du modèle qui permettent de caractériser des terroirs du vignoble des Côtes du Rhône.

STICS is a crop model developed at INRA (France) since 1996. It simulates the carbon, water and nitrogen balances of the crop-soil system driven by daily climatic data. It calculates both agricultural variables (yield in terms of quantity and quality) and environmental variables (water and nitrogen losses). One of the key elements of STICS is its adaptability to various crops (herbaceous, ligneous, annuals, perennials) made possible by the choice of generic parameters and options for both crop physiology and crop techniques. The present work deals first with the particularity of STICS to simulate vineyard in terms of trophic balance, energetic and water functioning and assessment of sugar and water contents of grape. Second it shows the various outputs which can be calculated by the model in order to characterize typical Côtes du Rhône zones.

Can grapevine tolerance to bunch rot be directly induced by groundcover management?

Botrytis bunch rot occurrence is the most important limitation for the wine industry in humid environments. The effect of grapevine vegetative growth on bunch rot expression results from direct effects (cluster architecture, nitrogen status among others) and indirect ones (via microclimate). Previous studies of our group showed strong differences in bunch rot incidence between floor management treatments: cover crop (CC) vs weed-free strips under the trellis with herbicide (H). We observed that in some circumstances this reduction in bunch rot incidence occurred without major vine growth differences among treatments. The aim of the present study was to test the general hypothesis that other factors unrelated to grapevine vegetative expression could be more relevant to grapevine susceptibility to bunch rot.

Characterized one of the largest collections of grapevine rootstocks (non-vinifera)

Microsatellite markers are a valuable tool to facilitate the management of germplasm collections and assess genetic diversity. This study reports the genetic characterization of a large collection of 379 rootstocks and other non-viniferaaccessions maintained at the University of Milan, Italy.

Influence of temperature and light on vegetative growth and bud fruitfulness of grapevine cv. Semillon

Aim: To investigate the effects of different levels of temperature and light intensity on grapevine vegetative growth and bud fruitfulness, which includes the number and size of inflorescence primordia in primary buds.

Quantification of quercetin and quercetin-3-glucoside in Nebbiolo red wines

Quercetin-3-glucoside, a grape flavonol defence metabolite, is extracted during winemaking and may undergo subsequent degradation in wines. Hydrolysation reactions lead to the formation of the aglycone quercetin, which presents limited solubility in the wine matrix and can induce visible precipitations.

Influence of must fining on oxygen consumption rate, oxidation susceptibility and electrochemical characteristics of different white grape musts

AIM: Pre-fermentative fining is one of the central steps of white wine production. Mainly aiming at reducing the levels of suspended solids, juice fining can also assist in reducing the content of oxidizable phenolics and therefore the susceptibility of juice to oxidation.
