Potencial alelopático de lixiviados de cultivos de cobertura y malezas sobre plantas jóvenes de vid
(2016)Las interacciones entre la vid y especies herbáceas pueden involucrar competencia por recursos y alelopatía. Se presume que determinados cultivos de cobertura y malezas poseen efectos alelopáticos sobre el crecimiento de ... -
Relationships among Gene Expression and Anthocyanin Composition of Malbec Grapevine Clones
(2014-07)Anthocyanin profiles are commonly used for grapevine cultivar identification because it is currently accepted that this trait is closely related to their genetic characteristics. Nevertheless, the extent of the variation ... -
Expression of grapevine AINTEGUMENTA-like genes is associated with variation in ovary and berry size
(2016-05)Fruit size is a highly important trait for most fruit and vegetable crops. This trait has been a main selection target and could be involved in divergent selection processes leading to the differentiation between modern ... -
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: ... -

Coberturas vegetales en viñedos bajo riego localizado, respuesta fisiológica de especies herbáceas nativas a diferentes ambientes
(Escuela para Graduados, Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2015)En Mendoza, Argentina es imprescindible regar los cultivos debido a las escasas precipitaciones y a la elevada evapotranspiración. El uso de coberturas vegetales es una herramienta sostenible con múltiples beneficios ... -
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 ... -
Co-fermentation of Syrah with various additions of Viognier: Effect on colour and phenolics during winemaking and bottle ageing
(2013-10)The impetus for the study described in this article was to assess the effect of co-fermentation of Syrah and Viognier in the phenolic chemistry and colour stability of the resulting wines and to document potential benefits ... -
Influence of fruit maturity, maceration length, and Ethanol amount on chemical and sensory properties of Merlot wines
(2013-12)Selected winemaking conditions were applied to fruit with ~20.3 and ~24.9 Brix over two seasons. Merlot grapes were harvested 33 (2011) and 34 (2012) days apart. At each harvest, half of the must was adjusted to emulate ... -
