Transmission of 16SrIII-J phytoplasmas by the leafhoppers Paratanus exitiousus and Bergallia valdiviana
(Mediterranean Phytopathological Union, 2019-09)Two of the most common leafhoppers present in Chile are the Cicadellidae Paratanus exitiosus and Bergallia valdiviana. They commonly occur in vineyards of central Chile, including some vineyards infected by phytoplasmas. ... -
Estimación de potencial hídrico en vid por medio de medidas termográficas y espectrales
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-04)El potencial hídrico foliar (ΨL) es una variable frecuentemente utilizada para medir el estado hídrico de los cultivos. Su medición con cámara de presión es lenta, lo que impide tomar un gran número de muestras. El objetivo ... -
Effect of transient thermal shocks on alcoholic fermentation performance
(Elsevier, 2019-10)Stuck and sluggish fermentations are among the main problems in winemaking industry leading to important economic losses. Several factors have been described as causes of stuck and sluggish fermentations, being exposure ... -
Spray-dried Ancellotta red wine: natural colorant with potential for food applications
(Springer, 2019-10-04)Ancellotta red wine (Vitis vinifera L.) was encapsulated by spray-drying (inlet and outlet temperatures were 145 °C and 70 °C, respectively) to obtain a wine powder with a low water activity (aw) using maltodextrin DE10 ... -
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 ... -
Persistence and reservoirs of Saccharomyces cerevisiae biodiversity in different vineyard niches
(Elsevier, 2019-09)Highlights: S. cerevisiae vineyard populations dynamically changed during grape growth cycle. Strains from ripe grapes showed highest diversity and distribution across vineyard. Buds in winter and bark from sprouting to ... -
Efecto del Tratamiento de Alta Presión Hidrostática en Parámetros de Calidad y Vida Útil de Cerezas (Prunus avium L.)
(Universidad Tecnológica Nacional, 2018-07-01)El objetivo del trabajo consistió en estudiar la evolución de parámetros de calidad de cerezas (parámetros cromáticos, textura, pH, recuento de microorganismos) sometidas a tratamientos con alta presión hidrostática (APH) ... -
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 ... -
