Climatic potential to produce grapes for wine-making in the tropical north region of Minas Gerais State, Brazil


The tropical north region of Minas Gerais State is one of the least developed of Brazil and viticulture could be an alternative to develop its agriculture zone. The objective of this work was to evaluate the wine grape production climatic potential of that region. The evaluations were carried out employing the Multicriteria Climatic Classification System (Geoviticulture MCC System), that utilizes three reference climatic indexes (Dryness Index – DI, Heliothermal Index – HI and Cool Night Index – CNI). This study integrates the concept of viticultural climate with intra-annual variability, that corresponds to the regions that, under natural climate conditions, change viticultural climate class as a result of the time of the year at which grapes can be produced – a definition to be used for regions with a hot climate where it is possible to have more than one grape harvest per year. Three locations – Pirapora (17º 21’S, 44º56’W, 489m), Montes Claros (16º43’S, 43º52’W, 647m) and Diamantina (18º15’S, 43º36’W, 1297m) – and two potential production cycles along the year – October-March (summer period) and April-September (winter period) – were evaluated. The results showed that in the summer period Pirapora and Montes Claros presented monthly average maximum temperature values (Tmax) varying from 29,4 ºC to 31,7 ºC, average minimum temperatures (Tmin) between 17,7 ºC and 20,4 ºC, and precipitation (P) varying from 76,8 mm to 223,8 mm, representing a ‘humid, very warm and with warm nights’ class of viticultural climate, according to MCC System. This climatic condition is similar to the summer period condition of the Brazilian San Francisco Valley (9º23’S, 40º29’W, 371,7m) grape-growing region, although with a higher DI. For the winter period, those two regions presented Tmax between 27,1ºC and 31,7ºC, Tmin between 12,1ºC and 18,2ºC, and P between 1,8 mm to 51,4 mm representing a ‘moderately dry, warm and with temperate nights’ according MCC System. Otherwise, the Diamantina summer period presented Tmax values between 24,4ºC and 25,3ºC, Tmin varying from 15,6ºC to 17,3ºC and P values between 99,2mm and 261,2mm, representing a ‘humid, temperate warm and with temperate nights’ viticultural climate. In the winter period, Diamantina Tmax values varied from 20,9ºC to 24,0ºC, Tmin varied between 11,8ºC and 15,9ºC and P varied between 7,8mm and 58,1mm. These values represent a ‘subhumid, temperate and with cool nights’ viticultural climate. Based on those results it can be concluded that the north region of Minas Gerais State has a great climatic potential to became a grape-growing for wine-making region, specially on the winter period, when the region viticultural climate presents conditions where vine will potentially face a certain level of dryness, an heliothermal global regime between temperate warm and warm, and with cool to temperate nights. The viticultural climate with intra-annual variability of the region, that offers a potential to produce grapes in the tropical winter period, represents a particular condition in relation to the world classic geoviticulture. The climatic groups of the regions with possibility to produce in the non classic periods of the year must be considered in the context of the tropical viticulture climate, presenting a distinct seasonal thermic evolution dynamic.

Physiological and growth reaction of Shiraz/101-14 Mgt to row orientation and soil water status

Advanced knowledge on grapevine row orientation is required to improve establishment, management and outcomes of vineyards on terroirs with different environmental conditions (climate, soil, topography) and in view of a future change to more extreme climatic conditions. The purpose of this study was to determine the combined effect of row orientation, plant water status and ripeness level on the physiological and viticultural reaction of Shiraz/101-14 Mgt.

Effects of mechanical leafing and deficit irrigation on Cabernet Sauvignon grown in warm climate of California

San Joaquin Valley accounts for 40% of wine grape acreage and produces 70% of wine grape in California. Fruit quality is one of most important factors which impact the economical sustainability of farming wine grapes in this region. Due to the recent drought and expected labor cost increase, the wine industry is thrilled to understand how to improve fruit quality while maintaining the yield with less water and labor input. The present study aims to study the interactive effects of mechanical leafing and deficit irrigation on yield and berry compositions of Cabernet Sauvignon grown in warm climate of California.

The effects of cane girdling on berry texture properties and the concentration of some aroma compounds in three table grape cultivars

The marketability of the table grapes is highly influenced by the consumer demand; therefore the market value of the table grapes is mainly characterized by its berry size, colour, taste and texture. Girdling could cause accumulation of several components in plants above the ringing of the phloem including clusters and resulting improved maturity. The aim of the experiments was to examine the effect of girdling on berry texture characteristics and aroma concentration.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot Blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.

Different yield regulation strategies in semi-minimal-pruned hedge (SMPH) and impact on bunch architecture

Yields in the novel viticulture training system Semi-Minimal-Pruned Hedge (SMPH) are generally higher compared to the traditional Vertical Shoot Positioning (VSP). Excessive yields have a negative impact on the vine and wine quality, which can result in substantial losses in yield in subsequent vintages (alternate bearing) or penalties in fruit quality. Therefore yield regulation is essential. The bunch architecture in SMPH differs from VSP. Generally there is a higher amount but smaller bunches with lower single berry weights in SMPH compared to VSP.
