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.

The impacts of frozen material-other-than-grapes (MOG) on aroma compounds of red wine varieties

An undesirable note called “floral taint” has been observed in red wines by winemakers in the Niagara region caused by large volumes of frozen leaves and petioles [materials-other-than-grapes (MOG)] introduced during mechanical harvest and subsequent winemaking late in the season. The volatiles, which we hypothesized are responsible, are primarily terpenes, norisoprenoids, and specific esters in frozen leaves and petioles. The purpose of this study was to investigate the volatile compounds which may cause the floral taint problem and explore how much of them (thresholds) may lead to the problem. Also, the glycosidic precursors of some of these compounds were analyzed to see the changes happening during frost events.

Aromatic profile of six different clones of Chardonnay grape berries in Minas Gerais (Brazil)

Aromas are one of the key points in food analysis since they are related to character, quality and consequently consumer acceptance. It is not different in the winery industry, where the aromatic profile is a combination of viticultural and oenological practices. Based on the development of more aromatic clones and on the potential to produce sparkling wines at Caldas, in the southern region of Minas Gerais (Brazil) (21°55´S and 46°23´W, altitude 1,100m), the aim of this work was the determination of volatile compounds in six different clones of Chardonnay grape berries to better understand which compounds add bouquet to the wine, and additionally comprehend the impacts of the edaphoclimatic and annual conditions on the improvement of grape-growing and winemaking practices.

Improving stilbenes in vitis Labrusca L. Grapes through methyl jasmonate applications

Grapes (Vitis sp.) are considered a major source of phenolic compounds such as flavonols, anthocyanins and stilbenes. Studies related to the beneficial effects of these compounds on health have encouraged research aimed at increasing their concentration in fruits. On this behalf, several plant growth regulators such as jasmonic acid and its volatile ester, methyl-jasmonate (MeJa), have demonstrated promising results in many fruits. However, Brazilian subtropical climate might interfere on treatment response. The present study aims to evaluate the application of MeJa in the pre-harvest period in Concord and Isabel Precoce grapes (Vitis labrusca L.).

Service crop effects on grapevine water and nitrogen status and yield under Mediterranean climate

Service crops in vineyard can provide multiple ecosystem services but they can also lead to competition with the grapevine for soil resources in the Mediterranean region due to potential severe droughts (Garcia et al., 2018). One of the levers of action to manage this competition is the choice of species adapted in terms of growth dynamics and water and nutrients’ needs. The objectives of this study were to determine the effect of temporary service crops on grapevine water and nitrogen status and grapevine yield and yield components in a Mediterranean vineyard.

Impact of deficit irrigation strategies on terpene concentration in Gewürztraminer grapes

Deficit irrigation is a viticultural practice often applied to improve the phenolic composition of red grapes and wines. However, the impact of this practice on grape terpenes – key aromatics for several grapes and wines – remains largely unknown. This study investigated the impact of deficit irrigation strategies on free and glycosylated terpenes in Gewürztraminer grapes. In a field study conducted in Oliver, BC, in 2016, 2017, and 2018, deficit irrigation regimes were applied to Gewürztraminer vines at different developmental stages (pre-veraison = Early Deficit, ED; post-veraison = Late Deficit, LD; throughout the season = Prolonged Deficit, PD). A well-irrigated control (CN) treatment was also established.
