Identification of second instar larvae of thrips (Thysanoptera: Thripidae) vectors of Orthotospovirus (Tospoviridae) in South America
(Wiley, 2022-05)Thrips (Thysanoptera: Thripidae) are the only vectors of Orthotospovirus, a group of viral pathogens that infect plants and cause major economic damage to crops. The virus is acquired by the vector only at the first and ... -
Identity and parentage of some South American grapevine cultivars present in Argentina
(2017)Background and Aims: Based on 19 nuclear simple sequence repeat markers and parental analysis, we aimed to identify and propose the pedigree of different accessions held at the Estación Experimental Agropecuaria Mendoza ... -
Impact of closure type and storage temperature on chemical and sensory composition of Malbec wines (Mendoza, Argentina) during aging in bottle
(Elsevier, 2019-07)Malbec is the flagship variety of Argentina mainly due to its high oenological value and plasticity to obtain different wine styles. During bottled aging, the chemical and organoleptic composition of wines is subject to ... -
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 ... -
Impact of micro-oxygenation timing and rate of addition on color stabilization and chromatic characteristics of Cabernet Sauvignon wines
(Elsevier, 2021-05)The presented study evaluated anthocyanins, anthocyanin-derived pigments and chromatic characteristics of six micro-oxygenation treatments resulting from applying oxygen at different times and rates. Oxygen was applied ... -
Impact of phenolic and polysaccharidic composition on commercial value of Argentinean Malbec and Cabernet Sauvignon wines
(Elsevier, 2012-01)Knowledge of the chemical composition of wine and its association with the commercial value constitutes an objective tool to assess quality and can be used as a marketing strategy. Phenolic compounds are very important ... -
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 ... -

(Instituto Multidisciplinario de Estudios Sociales (IMESC), Universidad Nacional de Cuyo, 2021-07)En este artículo proponemos analizar el impacto de la pandemia en el trabajo estacional agrícola retomando a Mendoza (Argentina) como caso de estudio, en la provincia la movilidad territorial para el trabajo estacional en ... -
In vitro cultures of Vitis vinifera L. cv. Chardonnay synthesize the phytoalexin nerolidol upon infection by Phaeoacremonium parasiticum
(2013)This study investigated terpene synthase (TPS) activity and terpene antifungal metabolites in calluses and cell suspension cultures of Vitis vinifera cv. Chardonnay infected with Phaecremonium parasiticum, one of the fungi ... -
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 ... -
Incidence of Grapevine Leafroll Associated Viruses -1, -2, and -3 in Mendoza vineyards
(2010-12)Viticulture is important in Argentina's economy, especially in the province of Mendoza, which is responsible for more than 75% of the crop cultivated area. In this work, we evaluated the incidence of Grapevine leafroll-associated ... -
Incidence of osmophilic yeasts and Zygosaccharomyces rouxii during the production of concentrate grape juices
(2017)Zygosaccharomyces rouxii is the main spoilage yeast of grape juice concentrates. Detection and identification of Z. rouxii during the production of grape juice concentrate is critical to prevent spoilage in the final ... -
Influence of fruit maturity, maceration length, and Ethanol amount on chemical and sensory properties of Merlot wines
(2013-12)Selected winemaking conditions were applied to fruit with ~20.3 and ~24.9 Brix over two seasons. Merlot grapes were harvested 33 (2011) and 34 (2012) days apart. At each harvest, half of the must was adjusted to emulate ... -
