Impact on Sensory and Aromatic Profile of Low Ethanol Malbec Wines Fermented by Sequential Culture of Hanseniaspora uvarum and Saccharomyces cerevisiae Native Yeasts
(MDPI, 2019-07)It is well known that high ethanol levels in wines adversely affect the perception of new wine consumers. Moreover, numerous issues, such as civil restrictions, health risk and trade barriers, are associated with high ... -
Selection of Native Non-Saccharomyces Yeasts with Biocontrol Activity against Spoilage Yeasts in Order to Produce Healthy Regional Wines
(MDPI, 2019-07)Two major spoilage yeasts in the wine industry, Brettanomyces bruxellensis and Zygosaccharomyces rouxii, produce off-flavors and gas, causing considerable economic losses. Traditionally, SO2 has been used in winemaking to ... -
Interactive effects of high temperature and water deficit on Malbec grapevines
(Wiley, 2019-06-26)Background and Aims: Studies of the interactive effects of drought and high temperature on the physiological responses of grapevines (Vitis spp.) are scarce. We tested whether well‐watered, potted vines were able to avoid ... -
In vitro plants of Vitis vinifera respond to infection with the fungus Phaeoacremonium parasiticum by synthesizing the phytoalexin nerolidol
(Springer, 2019-09)This study investigated terpene biosynthesis in basal and apical tissues of in vitro-grown plants of Vitis vinifera cv. Chardonnay infected or not (control) with Phaeoacremonium parasiticum. This pathogen is one of the ... -
Transcriptional regulation of the anthocyanin biosynthesis pathway in developing grapevine berries in cultivar ‘Malbec’ by putative R2R3 MYB negative regulators
(Elsevier, 2019-11)In grapevine, proanthocyanins (PAs) and anthocyanins are obtained via the phenylpropanoid pathway. These metabolites are synthesized in specific tissues of the berry and accumulate in different developmental stages. The ... -
Actividad forrajera de Acromyrmex striatus (Roger,1863) (Formicidae: Attini) en un viñedo orgánico en Mendoza, Argentina
(Ediciones INTA, 2019-08)Las hormigas cortadoras se convierten en plagas agrícolas, debido a su habilidad de utilizar especies vegetales como sustrato para el desarrollo del hongo simbionte que constituye su alimento. Los objetivos de este trabajo ... -
Exhausted grape marc and organic residues composting with polyethylene cover: process and quality evaluation as plant substrate
(Elsevier, 2019-09)In Argentina, wine production is one of the most important economic activities, producing a large quantities of organic wastes. Composting is a viable alternative to treat these residues, with the possibility to obtain ... -
Microwave-assisted extraction applied to Merlot grapes with contrasting maturity levels: effects on phenolic chemistry and wine color
(MDPI, 2019-01)Merlot grapes were harvested with three maturity levels (21.1, 23.1, and 25.1 Brix), and processed with or without the application of microwave-assisted extraction (MW). The detailed phenolic composition and color were ... -
Dissecting the genetic control of root and leaf tissue-specific anthocyanin pigmentation in carrot (Daucus carota L.)
(Springer, 2019-05-29)Purple carrots can accumulate large quantities of anthocyanins in their root tissues, as well as in other plant parts. This work investigated the genetic control underlying tissue-specific anthocyanin pigmentation in the ... -
First report of grapevine red blotch virus infecting grapevine in Argentina
(Springer, 2019-04)Argentina is the fifth wine producer worldwide and 10th global grapevine producer, with over 2,100,000 tons of grapes harvested in 2017. So far, 12 viruses have been identified in grapevine in Argentina (Debat et al. 2019). -
Biocontrol of postharvest Alternaria decay in table grapes from Argentina
(Elsevier, 2019-03-29)Postharvest diseases cause considerable losses of fruit during transportation and storage. Synthetic fungicides are primarily used to control them; however, the recent trend is to shif toward safer and more eco-friendly ... -
Chemical and sensory effects of cold soak, whole cluster fermentation, and stem additions in Pinot noir wines
(American Society for Enology and Viticulture, 2019-01)Pinot noir wines were produced over two consecutive vintages using four and six different winemaking techniques in 2014 and 2015, respectively. In addition to control wines, the separate and combined effect of cold soak ... -
No silver bullet for digital soil mapping: country-specific soil organic carbon estimates across Latin America
(2018-08)Country-specific soil organic carbon (SOC) estimates are the baseline for the Global SOC Map of the Global Soil Partnership (GSOCmap-GSP). This endeavor is key to explaining the uncertainty of global SOC estimates but ... -
Reduction of Zygosaccharomyces rouxii Population in Concentrated Grape Juices by Thermal Pasteurization and Hydrostatic High Pressure Processing
(Springer, 2019-02)Zygosaccharomyces rouxii is the most frequent spoilage yeast species detected in concentrated grape juice. In order to reduce Z. rouxii populations and consequently extend the microbiological shelf life of this product, ... -
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 ... -
Survival of the biological control agent Candida sake CPA‐1 on grapes under the influence of abiotic factors
(Wiley, 2014-09)Aims: As reliability of preharvest applications of biological control agents (BCAs) to control fruit pathogens is highly dependent on the survival of the selected organism, this study aimed to describe the population ... -
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 ... -
Carbohydrate reserve status of Malbec grapevines after several years of regulated deficit irrigation and crop load regulation
(Wiley, 2013-10)Background and Aims: Regulated deficit irrigation (RDI) and bunch thinning are two viticultural practices applied worldwide. There is limited knowledge, however, about their combined effects on carbohydrate dynamics and ... -
