Summary The anthocyanin composition of Tannat red wines obtained with four winemaking techniques was evaluated in different years. were elaborated traditional maceration (TM), cold pre‐fermentative maceration, delayed extraction anthocyanins and extended maceration. Two vinifications carried out for each technique, employing 70 kg grapes one. analysed by high‐performance liquid chromatography–diode array detection. results confirm the fundamental role grape on wines. had an important effect...
Berry size, composition
This study aimed to determine how within-plot soil heterogeneity combined with yearly climate variability can promote the of vine growth at plot level, and which soil-climate parameters influence final yield berry composition most. An 8-year experiment was conducted on grapevine in two zones a vineyard (1 ha) differentiated according vigour as determined by NDVI: high (HV) low (LV). The properties (depth, texture composition), plant (shoots roots) production (yield components composition)...
The spatial variability of vineyards can be characterised through precision viticulture that will allow setting the boundaries homogeneous management zones. This study aimed to evaluate impact soil and plant (site-specific management) increase yields improve berry quality. During three consecutive seasons, contrasting treatments designed ad hoc for two zones vigour pre-established by NDVI were tested: high zone (HV) low (LV). at reducing water nitrogen supply improving microclimatic...
Phenolic composition of Tannat variety grapes grown in South Uruguay and harvested during two consecutive years (1999 2000) was determined. The effect the cluster thinningin settingand veraison, etephon applications, pruningat 4 6 buds per rod on phenolic their respective red wines compared. During harvest, which took place technological maturity, maturity indices were estimated. Wines analysed a month after alcoholic fermentation, determiningits colour content. different treatments had...
The Latin American Maize Project (LAMP) evaluated nearly 12 000 maize ( Zea mays L.) accessions in countries to select germplasm that can be used breeding programs improve commercial materials. In Argentina, Chile, Uruguay, and the USA, 1692 988 native were first second period, respectively. Sixty‐nine selected all third stage. Accessions per se showed silk delay, indicating a lack of adaptation. 69 topcrossed with B73 × B14A, Oh43 MolT, SR76 four (i) identify temperate from America USA...
Summary The phenolic potential of the grapes Tannat, Cabernet Sauvignon and Merlot produced in south region Uruguay was analysed four years. Tannat had highest total richness (A280 = 80.0), anthocyanin (ApH1 2540 mg L −1 ) extractable (ApH3.2 1269 ), although there were important differences between Representative winemaking each vineyard carried out. verified indexes related to colour polyphenolic composition wines. correlations wines very high. estimation extractability anthocyanins allow...
Climate scenarios in the medium and long term (2010-2070) foresee increased summer rainfall for Uruguay region, with water deficits excess episodes. Although at international level irrigation viticulture has a experience tradition, local (Uruguay), only 10% of vineyard surface area implements fixed or complementary system supply their crops. This work aimed to model crop requirements southern based on pedo-climatic variables. In addition, plant response controlled deficit was evaluated two...
<p style="text-align: justify;"><strong>Aims:</strong> Vineyards in Uruguay are concentrated over soils formed from Quaternary sediments; however, recent years vineyard surface metamorphic rocks has increased. In this context, study assessed the relationships between soil physical properties and grapevine vegetative development, yield berry composition, order to understand how vine response is affected characterize viticultural production potential for different regions....
The current study aimed to establish which meteorological conditions have the strongest impact on grapevine yield, sanitary status and berry composition, as well checking their relative importance in relation management practices variety.Weather data was correlated grape composition of three varieties (Cabernet-Sauvignon, Merlot Tannat) under two trellis systems (lyre vertical shoot positioning), with or without yield control (pruning type cluster thinning) over four seasons throughout south...
This paper shows the results of a study carried out during four years (2001-2004). Its aim was characterization Tannat, Cabernet Sauvignon and Merlot grapes cultivated in south Uruguay. The were evaluated to qualify enological potential these varieties Vitis vinifera L. Typical cultivation situations region included each variety. analysed at harvest for determination global composition polyphenolic potential. Tannat presented very different characteristics relation other varieties. had...
