(BMC, 2010-08)Background: Symptoms of grapevine leafroll disease (GLRD) in red-fruited wine grape (Vitis vinifera L.) cultivars consist of green veins and red and reddish-purple discoloration of inter-veinal areas of leaves. The ... -
Molecular and ampelographic characterization of Pisco grapevine accessions conserved in a germplasm collection center of the Ica, Peru = Caracterización molecular y ampelográfica de accesiones de vides pisqueras conservadas en un centro de colección de germoplasma de Ica, Perú
(Facultad de Ciencias Agropecuarias, Universidad de Trujillo (Perú), 2021-12)Pisco is a distillate of cultural and economic importance for Peru, made from heterogeneous vine varieties called "pisqueras", covered by a Pisco Denomination of Origin legislation. The aim was to confirm the varietal ... -
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 ... -
Monitoring of killer yeast populations in mixed cultures: influence of incubation temperature of microvinifications samples
(2012-11)Killer yeasts are frequently used to combat and prevent contamination by wild-type yeasts during wine production and they can even dominate the wine fermentation. Stuck and sluggish fermentations can be caused by an ... -
Morphology and hydraulic architecture of Vitis vinífera L. cv. Syrah and Torrontes Riojano plants are unaffected by variations in red to far-red ratio
(2016)Plants have evolved an array of specific photoreceptors to acclimate to the light environment. By sensing light signals, photoreceptors modulate plant morphology, carbon- and water-physiology, crop yield and quality of ... -
Mulita o burrito de la vid y de los frutales Naupactus xanthographus
(EEA La Consulta, INTA, 2022-06)Es un gorgojo de la familia Curculionidae. Los huevos se encuentran agrupados y tienen forma ovoide de color amarillo-anaranjado, de 1-5 mm. Las larvas son blanco-amarillentas, con cabeza de color castaño oscuro, ápodas, ... -
Multi-enzyme production by pure and mixed cultures of Saccharomyces and non-Saccharomyces yeasts during wine fermentation
(Elsevier, 2012-04-02)Saccharomyces and non-Saccharomyces yeasts release enzymes that are able to transform neutral compounds of grape berries into active aromatic compounds, a process that enhances the sensory attributes of wines. So far, there ... -
Multi-method sensory approach to describe the effect of microwave-assisted extraction and addition of stems on the mouthfeel sensations of Bonarda wines from Mendoza (Argentina)
(PAGEPress, 2022-11-25)The Bonarda variety has been used as a base for common red wines due to its contribution to color and low level of astringency as a consequence of its relative low tannin concentration. The use of MicrowaveAssisted Extraction ... -
Mutagenesis, screening and isolation of Brettanomyces bruxellensis mutants with reduced 4-ethylphenol production
(Springer, 2021-01)The use of non-conventional yeast species to obtain interesting flavors and aromas has become a new trend in the fermented beverages industry. Among such species, Brettanomyces bruxellensis (B. bruxellensis) has been ... -
Natural occurrence of Ochratoxin A in musts, wines and grape vine fruits from grapes harvested in Argentina
(2010-08)In this study, ochratoxin A (OTA) occurrence in Argentinean musts, wines and dried vine fruits was evaluated, alongside with the performance of OchraStarTM columns for OTA extraction. In all the three matrices analyzed, ... -
Nematodo de la vid o nematodo daga Xiphinema spp.
(EEA La Consulta, INTA, 2022-08)Son nematodos relativamente grandes. Los huevos son esféricos e hialinos. Las larvas presentan cuatro estadios morfológicamente similares al adulto, aunque de menor tamaño. Los adultos pueden observarse a ojo desnudo, ya ... -
Nematodo de las lesiones radicales Pratylenchus spp.
(EEA La Consulta, INTA, 2022-09-19)Los huevos son depositados individualmente en las raíces o en el suelo. Las larvas presentan tres estadios filiformes semejantes al estado adulto; el primero se desarrolla en el interior del huevo, el segundo migra en busca ... -
Night-time sap flow is parabolically linked to midday water potential for field-grown almond trees
(2013-11)To quantify night-time (S n) and diurnal (S d) tree water uptake, two sets of sap flow sensors (heat-pulse compensated) were installed per tree in the north-east and south-west sides of the trunk in three trees per treatment. ... -
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 ... -
Non‐structural carbohydrates and sugar export in grapevine leaves exposed to different light regimes
(Wiley, 2020-11)Light is a main environmental factor that determines leaf microclimate within the vine, as well as its photosynthesis and carbohydrate metabolism. This study aimed to examine the relationships between photosynthesis, ... -
