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, ... -
Modulation of flavonoid biosynthetic pathway genes and anthocyanins due to virus infection in grapevine (Vitis viniferaL.) leaves
(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 ... -
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 ... -
Relaciones entre cavitación y cierre estomático en vides sometidas a déficit hídrico
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo., 2011)La cavitación es una disfunción fisiológica que ocurre en el xilema de las plantas cuando estas están bajo déficit hídrico, y que entraña una pérdida de su conductancia hidráulica (kL), cuando algunos vasos se llenan de ... -
Regulación de la hidratación y la turgencia foliares por mecanismos evitadores del estrés, y resistencia a déficit hídrico en vid
(Universidad Nacional de Cuyo, 2011)El transporte del agua en las plantas es impulsado por diferencias de energía libre entre el suelo y la atmósfera, y está regulado por mecanismos biológicos evitadores, como el cierre estomático. La hidratación y la turgencia ... -
A simple model of the diffusion phenomena taking place during the debittering process of green table olives
(Instituto de la Grasa, CSIC (España), 2011)The change in the concentration of sodium and calcium ions in the olive flesh and in the lye during the debittering process was quantified. The average concentration of Na increased from 0.0045 to 0,395 meq Na/g of olive ... -
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 ... -
Biodiversity of Saccharomyces cerevisiae populations in Malbec vineyards from the “Zona Alta del Río Mendoza” region in Argentina
(Elsevier, 2011-12-15)The “Zona Alta del Río Mendoza” (ZARM) is the major Malbec grape viticulture region of Argentina. The aim of the present study was to explore Saccharomyces cerevisiae biodiversity in ZARM vineyards. Interdelta PCR and RFLP ... -
Evaluación del efecto de distintos regímenes de riego como estrategia de riego deficitario controlado en tabaco (Nicotiana tabacum L.)
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2012)Con el fin de investigar el efecto de diferentes métodos y estrategias de riego deficitario sobre el crecimiento y producción del tabaco tipo Virginia (Nicotiana tabacum L.), se llevó a cabo una investigación a campo ... -
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 ... -
Biocontrol of Botrytis cinerea in table grapes by non-pathogenic indigenous Saccharomyces cerevisiae yeasts isolated from viticultural environments in Argentina
(Elsevier, 2012-02)Botrytis cinerea, the causal agent of gray mold, is an important disease of grapes. Yeasts are members of the epiphytic microbial community on surfaces of fruits and vegetables and because some yeasts inhibit fungi they ... -
Phenolic characterisation of red wines from different grape varieties cultivated in Mendoza province (Argentina)
(Wiley, 2012-02)Background: Knowledge of the chemical composition of wine and its association with the grape variety/cultivar is of paramount importance in oenology and a necessary tool for marketing. Phenolic compounds are very important ... -
Effects of organic amendment application on soil quality and garlic yield in central-western Argentina
(Bentham Open, 2012-02)We analyzed during two garlic crop cycles, the effects of chicken manure and vermicompost on soil chemical and biological properties in an agricultural farm irrigated with municipal wastewater of central-western Argentina. ... -
Selection of indigenous Saccharomyces cerevisiae strains to ferment red musts at low temperature
(2012-03)The aim of this work was to select native Saccharomyces cerevisiae strains to conduct the alcoholic fermentation of red must at low temperature (15°C), thus producing volatile compounds that enhance the aromatic profile ... -
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 ... -
