Combination of pre-fermentative and fermentative strategies to produce Malbec wines of lower alcohol and pH, with high chemical and sensory quality
(International Viticulture and Enology Society (IVES), 2020)The climatic conditions in some wine regions imply in many cases the important delay in the harvest date to achieve an appropriate phenolic maturity in red grape varieties, leading to wines with high pH and alcohol content. ... -
Combined effect of prefermentative cold soak and SO2 additions in Barbera D’Asti and Malbec wines : anthocyanin composition, chromatic and sensory properties
(2016)The effects of prefermentative cold soak (CS) combined with two SO2 additions (50 and 100 mg L1) on the anthocyanin composition, chromatic properties and sensory attributes of Barbera D'Asti and Malbec wines were studied. ... -
Combined effect of temperature and ammonium addition on fermentation profile and volatile aroma composition of Torrontés Riojano wines
(2018-01)The effects of process temperature and ammonium supplementation on fermentation profile, volatile aroma composition and wine sensory characteristics were evaluated in Torrontés Riojano (Vitis vinifera L.) wines from Mendoza ... -
Comparación de las respuestas al estrés hídrico y salino de los portainjertos de vid 1103P y 101-14Mgt, injertados con Cabernet Sauvignon = Comparing water deficit and saline stress between 1103P and 101-14Mgt rootstocks, grafted with Cabernet Sauvignon
(2017)En zonas áridas bajo riego, los viñedos enfrentan condiciones de déficit hídrico y salinidad. Como frecuentemente estos factores de estrés ocurren simultáneamente, es difícil evaluar la gravedad relativa de cada uno de ... -
Comportamiento alimentario de Frankliniella occidentalis (Pergande) y la incidencia de TSWV (Tomato Spotted Wild Virus) en plantas de papa del cultivar Innovador

Comportamiento isohídrico o anisohídrico en vides…. ¿Una controversia sin fin?
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)De acuerdo al tipo de respuesta estomática, muchas especies han sido clasificadas como isohídricas o anisohídricas. Las plantas isohídricas son aquellas que cierran sus estomas cuando sensan una caída en el potencial hídrico ... -
Compost tea and bioslurry as plant biostimulants. Part 2: biofertilizer test in ornamental flowers
(Taylor and Francis, 2023-01)The present study tested the effect of aerated (AM), non-aerated (NAM), a 1:1 combination of both compost teas (A-NAM), and bioslurry (B) as bio-fertilizers in two ornamental plants growing in different substrates. The ... -
Condiciones para que la incorporación de energía solar en viñedos sea una opción económica y ambientalmente sostenible: caso de estudio de Mendoza, Argentina
(Asociación Argentina de Energías Renovables y Ambientales (ASADES), 2021-12)El objetivo del trabajo fue analizar las condiciones económicas-financieras y técnicas-productivas bajo las cuales la incorporación de energía solar para riego en viñedos es sostenible. Para esto se consideró una finca con ... -
Construction of low-ethanol-wine yeasts through partial deletion of the Saccharomyces cerevisiae PDC2 gene
(2017)We propose an alternative GMO based strategy to obtain Saccharomyces cerevisiae mutant strains with a slight reduction in their ability to produce ethanol, but with a moderate impact on the yeast metabolism. Through ... -
Control of Ochratoxin A production in grapes
(2012-05)Ochratoxin A (OTA) is a mycotoxin commonly present in cereals, grapes, coffee, spices, and cocoa. Even though the main objective of the food and feed chain processors and distributors is to avoid the extended contamination ... -
Culture-dependent and independent techniques applied to monitor yeast species on cold soak at different temperatures in winemaking
(2016)Transformation of grape must into wine is a process that may vary according to the consumers' requirements. Application of cold soak prior to alcoholic fermentation is a common practice in cellars in order to enhance flavor ... -
