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 ... -
Influencia de dos técnicas de maceración sobre la composición polifenólica, aromática y las características organolépticas de vinos cv. Merlot
(Infonet, 2007)La técnica de maceración empleada, así como la gestión de la misma, condiciona fuertemente el estilo de vino a obtener. En el marco de un ensayo llevado a cabo en la planta piloto del Centro de Estudios de Enología de ... -
Inoculation strategies to improve persistence and implantation of commercial S. cerevisiae strains in red wines produced with prefermentative cold soak
(Elsevier, 2018)Prefermentative cold soak is a winemaking technique aimed at enhancing aroma and colour extraction in red wines. This study aimed at evaluating implantation and persistence rates of commercial active dry yeast strains (ADY) ... -
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 ... -
Is Taeniothrips inconsequens (Thysanoptera: Thripidae) a pest of stone and pip fruit trees in Argentina?
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2022-06-13)The presence of the “pear thrips” Taeniothrips inconsequens has been cited in Argentina in 1921 by Teresa Joan. This has affected exports of fruit tree propagation materials. However currently there is a concern about that ... -
