Agroclimatic zonation for vine growing in Maranhão State, Brazil

Abstract

Les indices agroclimatiques concernant le bilan hydrique et la température moyenne de l’air, ont été utilisés pour la caractérisation des zones avec différentes aptitudes pour la viticulture de vin (Vitis vinifera L.) dans l’état du Maranhão, Brésil. Le bilan hydrique de THORNTHWAITE et MATHER (1955), pour une réserve hydrique utile du sol de 120 mm, a été utilisé pour la détermination d’un «Indice Hydrique Annuel de THORNTHWAITE» (Ih), capable de caractériser les conditions hydri1ques idéales pour la viticulture, pour les régions de dispersion naturelle et également pour les régions de production commerciale. Les valeurs climatiques mensuelles de température et pluie ont été utilisées pour le calcul du bilan hydrique Ih sur 88 emplacements dans· l’état du Maranhâo. Les résultats ont permis de constater que l’état n’a aucune limitation thermique pour le développement de la vigne. L’indice Ih a permis la classification des régions dans trois différentes zones agroclimatiques, qui correspondent à trois classes d’aptitude viticole : pleine aptitude (Ih < -20) ; aptitude régulière (-20 < Ih < 60) et inaptitude (Ih > 60). L’étude a permis de conclure que, sous conditions irriguées dans l’état du Maranhão, la viticulture pour la production de raisin et vin pourra être recommandée surtout dans les communes de Sao Félix de Balsas, Loreto, Benedito Leite, Nova York, Pastos Bons, Buriti Bravo, Fortuna, Govemador Luiz Rocha, Jatobâ, Sao Domingos do Maranhao et Graça Aranha.

The use of agroclimatic indexes based on water balance and air temperature means, allowed the characterisation of areas with different aptitude for grape (Vitis vinifera L.) crop growth in Maranhao State, Brazil. THORNTHWAITE and MATHER (1955) water balance for a 120 mm soil moisture capacity, of the regions of natural dispersion and of areas of commercial crop production was used to determine the annual hydrie index of THORNTHWAITE (Ih) in the characterisation of ideal hydric conditions of climate for crop growth. Monthly climatic values of temperature and rainfall were used to obtain the water balance for the same soil moisture capacity for 88 locations of Maranhao State. lt was observed that the State has no thermal limitation for grape growing. The hydric zones resulted in three classes of agroclimatic aptitude: Full aptitude (Ih < -20); Regular aptitude (-20 < Ih < 60) and Inaptitude (Ih > 60). Under irrigated conditions, the vine crop in Maranhao state may be encouraged mainly in the municipal districts of Sao Félix de Balsas, Loreto, Benedito Leite, Nova York, Pastos Bons, Buriti Bravo, Fortuna, Governador Luiz Rocha, Jatoba, Sao Domingos do Maranhao and Graça Aranha.

Effect of partial net shading on the temperature and radiation in the grapevine canopy, consequences on the grape quality of cv. Gros Manseng in PDO Pacherenc-du-vic-Bilh

As elsewhere, southwestern France vineyards face more recurrent summer heat waves these last years. Among the possibilities of adaptation to this climate changing parameter, the use of net shading is a technique that allow for limiting canopy exposure to radiations. In this trial, we tested net shading installed on one face of the canopy, on a north-south row-oriented plot of cv. Gros Manseng trained on VSP system in the PDO Pacherenc-du-Vic-Bilh. The purpose was to characterize the effects on the ambient canopy temperatures and radiations during the season and to observe the consequences on the composition of grapes and wines. Two sorts of net were used with two levels of obstruction (50% and 75%) of the photosynthesis active radiation (PAR). They have been installed on the west side of the canopy and compared to a netless control. Temperature and PAR sensors registered hourly data during the season. On specific summer day (hot and sunny) manual measurements took also place on bunches (temperature) and in different spots of the canopy (PAR). The results showed that, on clear days, the radiation is lowered by the shade nets respecting the supplier criteria. The effects on the ambient canopy temperature were inconstant on this plot when we observed the data from the global period of shading between fruit set and harvest. However, during hot days (>30°C), the temperature in the canopy was reduced during afternoon and the temperature of the bunch surface was reduced as well comparing to the control. A decrease of the maturity parameters of the berries, sugar and acidity, was also observed. Concerning the wine aromatic potential, no differences clearly appeared.

Plant nitrogen assimilation and partitioning as a function of crop load

Aims: The optimization of nitrogen use efficiency (NUE, i.e. uptake, assimilation and partitioning) is a solution towards the sustainable production of premium wines, while reducing fertilization and environmental impact. The influence of crop load on the accumulation of N compounds in fruits is still poorly understood. The present study assesses the impacts of bunch thinning on NUE and the consequences on the free amino N (FAN) profile in fruits.

WINE LEES AS A SOURCE OF NITROGEN FOR OENOCOCCUS OENI TO IMPROVE MALOLACTIC FERMENTATION PERFORMANCE

Malolactic fermentation (MLF) is a desired process in red and acidic white wines, after alcoholic fermentation (AF), carried out by the lactic acid bacterium (LAB) Oenococcus oeni. The advantages are an increase of pH, microbiological stabilization and organoleptic improvement of the final wine. However, the presence of stress factors such as ethanol, low pH, high total SO2, lack of nutrients and presence of inhibitors, could affect the successful completion of MLF [1]. Changes in amino acid composition and deficiencies in peptides after AF, showed that MLF can be delayed, signaling its importance for bacterial growth and L-malic acid degradation during MLF [2].

Impact of winemaking processes on wine polysaccharides, improving by qNMR

Today the knowledge in terms of molecular composition of the colloidal matrix is ​​not enough in order to control its stability, according to the number of winemaking and wine stabilization processes. The physico-chemical processes during the winemaking change the composition and quantity of wine macromolecules. The goal today is to determine which analytical techniques will allow to discriminate these winemaking processes in order to better understand their impact on colloidal matrix stability as well as which molecules are responsible for its instabilities. METHODS: Wines obtained after conventional winemaking were subjected to different fining and chemical stabilization treatments. Different methods were used to investigate the wine macromolecular composition and stability after chemical stabilization, including quantitative and qualitative analyzes of total soluble polysaccharides by extraction under acidified ethanol, and by size exclusion separation as well as qNMR metabolomics. RESULTS: Observation of a slight difference at the quantitative level using classical analysis between the winemaking processes was observed as well as a strong discrimination by qNMR metabolomics.
