Nucleotide sequence of key genes from the biosynthesis pathway of the major flavonoid in “Malbec” and “Cabernet Sauvignon”
(2015)In red wines, important sensory attributes such as color and astringency are the result of the accumulation of anthocyanins, which are located in the berry skin (and in the pulp of teinturier cultivars). Each cultivar has ... -
Biological control as a strategy to reduce the impact of mycotoxins in peanuts, grapes and cereals in Argentina
(2015)Mycotoxins including aflatoxins, deoxynivalenol, fumonisins and ochratoxin A are among the main fungal secondary metabolites detected as natural contaminants in South America in different commodities such as peanuts ... -
Efecto del 1-metilciclopropeno [1-MCP] sobre la calidad y vida postcosecha de cerezas = Effect of 1-methylcyclopropene (1-MCP) on quality and shelf-life of sweet cherries
(Asociación Iberoamericana de Tecnología Postcosecha, 2015)En la provincia de Mendoza, Argentina, la cereza (Prunus avium L.) es un cultivo de importancia ya que puede comercializarse como primicia en los mercados de contraestación tales como Europa y Estados Unidos. El uso del ... -
Germplasm evaluation of the native cultivar “Torrontes Riojano” (Vitis vinífera L.) collected in the Northwest of Argentina
(2015)The cultivar ‘Torrontés Riojano’ (Vitis vinifera L.) was derived from a cross of ‘Muscat of Alexandria’ and ‘Criolla Chica’. Its origin was probably not a directed cross in Mendoza Argentina during the colonial period. ... -
Sensory and chemical effects of two alternatives of prefermentative cold soak in Malbec wines during winemaking and bottle ageing
(2015)Two alternatives of cold soak (CS), traditional external refrigeration (CS‐T) and use of solid CO2 (CS‐DI), were evaluated in Malbec wines and contrasted against a control (C) during winemaking and up to 24 months of bottle ... -
Review: critical appraisal of methods to investigate the effect of temperature on grapevine berry composition
(Wiley, 2015-02)The grapevine is an economically important crop and a model species of long‐lived perennials widely used in bioclimatic studies. Ambient temperature modulates berry composition, hence the significant research effort in ... -
Fruit-localized photoreceptors increase phenolic compounds in berry skins of field-grown Vitis vinifera L. cv. Malbec
(2015-02)Sunlight exposure has multiple effect on fruits, as it affects the light climate perceived by fruit photoreceptors and fruit tissue temperature. In grapes (Vitis vinifera L.), light exposure can have a strong effect on ... -
Germination of six native perennial grasses that can be used as potential soil cover crops in drip-irrigated vineyards in semiarid environs of Argentina
(2015-02)Native desert plants have structural adaptations that maximize photosynthesis rates and minimize water loss. They can be successfully utilized as soil cover crops in drip-irrigated vineyards where water availability is ... -
Yeast population dynamics during prefermentative cold soak of Cabernet Sauvignon and Malbec wines
(2015-04)Prefermentative cold soak is a widely used technique in red wine production, but the impact on the development of native yeast species is hardly described. The aim of this work was to analyse the dynamics and diversity of ... -
Evaluation of different chemical preservatives to control Zygosaccharomyces rouxii growth in high sugar culture media
(Elsevier, 2015-04)Zygosaccharomyces rouxii is an osmophilic yeast responsible for a large amount of economic loss in high sugar food production. Statistical modelling techniques were used in the present study to assess the individual effects ... -
Regulated Deficit Irrigation Alters Anthocyanins, Tannins and Sensory Properties of Cabernet Sauvignon Grapes and Wines
(2015-04)Four regulated deficit irrigation (RDI) regimes were applied to Cabernet Sauvignon grapes, which were analyzed for phenolics and also made into wine over three consecutive growing seasons. Relative to an industry standard ... -
Partial molecular and biological characterization of grapevine leafroll-associated virus 2 isolates from Argentina
(2015-05)Grapevine leafroll is one of the most important viral disease affecting grapevines the world over. One of the viruses associated with this disease is Grapevine leafroll associated virus 2 (GLRaV-2), which has two remarkable ... -
Chemical, chromatic, and sensory attributes of 6 red wines produced with prefermentative cold soak
(2015-05-01)Six red grape cultivars, Barbera D’Asti, Cabernet Sauvignon, Malbec, Merlot, Pinot Noir and Syrah, were produced with or without prefermentative cold soak (CS). Cold soak had no effect on the basic chemical composition of ... -
Evaluation of dihydroquercetin-3-O-glucoside from Malbec grapes as copigment of malvidin-3-O-glucoside
(2015-05-15)Malbec is a wine grape variety of great phenolic potential characterized for its high levels of anthocyanins and dihydroflavonols. To evaluate the possible implication of dihydroflavonols in the expression of red wine color ... -
Impact of elevated temperature and water deficit on the chemical and sensory profiles of Barossa Shiraz grapes and wines
(Wiley, 2015-06)Background and Aims: Interactions are the main causes of complexity in field experiments; however, no studies have combined water and temperature regimes in field‐growing vines. Here we assessed grape and wine attributes ... -
Molecular and enological characterization of a natural Saccharomyces uvarum and Saccharomyces cerevisiae hybrid
(2015-07)Saccharomyces cerevisiae plays a main role in the winemaking process, although other species, like Saccharomyces uvarum or Saccharomyces paradoxus, have been associated with must fermentations. It has been reported in ... -
Relation between coumarate decarboxylase and vinylphenol reductase activity with regard to the production of volatile phenols by native Dekkera bruxellensis strains under ‘wine-like’ conditions
