First american records of Aphis intybi (Hemiptera: Aphididae) with notes on two other related adventive species in Argentina
(Florida Entomological Society, 2012-12)Aphis intybi Koch is recorded for the first time in North and South America. Measurements for the identification of this species in comparison with Aphis craccivora Koch are given. Aphis cytisorum Hartig is recorded for ... -
First report of Dactylonectria alcacerensis, Dactylonectria macrodidyma and Ilyonectria liriodendri associated with black-foot disease of grapevine in Argentina
(American Phytopathological Society, 2022-03-07)Black-foot is a fungal disease that affects young vines and planting material in the countries where grapevines are cultivated. During the 2018 grape-growing season, symptoms of reduced vigor, short internodes, leaf ... -
First report of grapevine red blotch virus infecting grapevine in Argentina
(Springer, 2019-04)Argentina is the fifth wine producer worldwide and 10th global grapevine producer, with over 2,100,000 tons of grapes harvested in 2017. So far, 12 viruses have been identified in grapevine in Argentina (Debat et al. 2019). -
Foro Regional Los Desafíos de la Gestión Territorial Rural
(Ediciones INTA, 2018)En el libro se encuentran compiladas las conferencias de este Foro Regional (2015-2016) con el fin de generar un espacio de pensamiento sobre los procesos de transformación territorial que afectan al desarrollo y la ... -
Free Volatile Compounds of cv. Pedro Giménez (Vitis vinifera L.) White Grape Must Grown in San Juan, Argentina
(2018)The free aromatic composition of must from Pedro Giménez grapes, grown in San Juan, Argentina, was characterised. Samples from the vintages of 2008 and 2009 were analysed by gas chromatography–mass spectrometry–solid phase ... -
Fruit-localized photoreceptors increase phenolic compounds in berry skins of field-grown Vitis vinifera L. cv. Malbec
(2015-02)Sunlight exposure has multiple effect on fruits, as it affects the light climate perceived by fruit photoreceptors and fruit tissue temperature. In grapes (Vitis vinifera L.), light exposure can have a strong effect on ... -
Generation of a non-transgenic genetically improved yeast strain for wine production from nitrogen-deficient musts
(MDPI, 2020)The yeast Saccharomyces cerevisiae is the main species responsible for the process that involves the transformation of grape must into wine, with the initial nitrogen in the grape must being vital for it. One of the main ... -
Generation of intra- and interspecific Saccharomyces hybrids with improved oenological and aromatic properties
(Wiley, 2022-04)Non-wine yeasts could enhance the aroma and organoleptic profile of wines. However, compared to wine strains, they have specific intolerances to winemaking conditions. To solve this problem, we generated intra- and ... -
Genetic and Transcription Profile Analysis of Tissue-Specific Anthocyanin Pigmentation in Carrot Root Phloem
(MDPI, 2021-09)In purple carrots, anthocyanin pigmentation can be expressed in the entire root, or it can display tissue specific-patterns. Within the phloem, purple pigmentation can be found in the outer phloem (OP) (also called the ... -
Genetic characterization of grapevine-infecting Botrytis cinerea isolates from Argentina = Caracterización genética de aislamientos de Botrytis cinerea obtenidos en vides de Argentina
(2010-06)Background: Botrytis cinerea is an ascomycete with a high genetic diversity and complex population structure, as reported from several hosts and sites. However, nothing is known about its genetic diversity in Argentina. Aims: ... -
Genome-wide gene expression of a natural hybrid between Saccharomyces cerevisiae and S. kudriavzevii under enological conditions
(Elsevier, 2012-07-16)The species Saccharomyces cerevisiae plays a predominant role in the wine making process. However, other species have been associated with must fermentation, such as Saccharomyces uvarum (Saccharomyces bayanus var. uvarum) ... -
Genomic and phenotypic comparison between similar wine yeast strains of Saccharomyces cerevisiae from different geographic origins
(Wiley, 2010-05)Aims: To study genomic and phenotypic changes in wine yeasts produced in short time periods analysing yeast strains possibly derived from commercial strains recently dispersed. Methods and Results: We conducted a genomic ... -
Germination of six native perennial grasses that can be used as potential soil cover crops in drip-irrigated vineyards in semiarid environs of Argentina
(2015-02)Native desert plants have structural adaptations that maximize photosynthesis rates and minimize water loss. They can be successfully utilized as soil cover crops in drip-irrigated vineyards where water availability is ... -
Germplasm evaluation of the native cultivar “Torrontes Riojano” (Vitis vinífera L.) collected in the Northwest of Argentina
(2015)The cultivar ‘Torrontés Riojano’ (Vitis vinifera L.) was derived from a cross of ‘Muscat of Alexandria’ and ‘Criolla Chica’. Its origin was probably not a directed cross in Mendoza Argentina during the colonial period. ... -

Grafolita, polilla negra o gusano del brote Cydia molesta
(EEA La Consulta, INTA, 2022-09-21)Los huevos son pequeños, de 0,8 mm de diámetro, de forma lenticular y contorno elíptico. Poco después de la postura presentan reflejos irisados, para luego tornarse amarillentos. Las larvas en un principio son de color ... -
Grapevine morphological shade acclimation is mediated by light quality whereas hydraulic shade acclimation is mediated by light intensity
(Elsevier, 2021-06)Plants acclimate to shade by sensing light signals such as low photosynthetic active radiation (PAR), low blue light (BL) levels and low red-to-far red ratios (R:FR) trough plant photoreceptors cross talk. We previously ... -
Growth response of Saccharomyces cerevisiae strains to stressors associated to the vine cycle
(Elsevier, 2022-03-07)Saccharomyces cerevisiae isolates from grapes, soil, vine bark and buds collected at seven phenological stages of an annual growth cycle, were molecular typed by Microsatellite Multiplex PCR. Subsequently 30 S. cerevisiae ... -
