Climate effect on Avena fatua field emergence dynamics: a 38-year experiment in the Semiarid Pampean Region of Argentina
(Wiley, 2022-02)Climate events modulate weed population dynamics mainly by influencing field seedling emergence patterns. Field experiments aiming to study the influence of climate on the early-stage establishment of weeds are of utmost ... -
Effect of water availability and seed source on physical dormancy break of Vicia villosa ssp. villosa
(2016-09)Physical dormancy (PY) plays a crucial role in the control of the reseeding process of Vicia villosa Roth, a winter annual species cultivated for pasture and hay, naturalized in several semi-arid temperate agroecosystems. ... -
Genetic diversity among alfalfa genotypes [Medicago sativa L.] of nom-dormant cultivars using SSR markers and agronomic traits = Análisis de la diversidad genética en genotipos de alfalfa (Medicago sativa L.) sin dormición, mediante el uso de marcadores SSR y caracteres agronómicos
(2013)The aim of this study was to assess genetic diversity among 40 alfalfa (Medicago sativa L.) genotypes of different non-dormant (FD=8) cultivars. Biomass yield, regrowth speed and reaction to spring black stem, lepto leaf ... -
Physical seed dormancy in native legume species of Argentina
(Sociedad Argentina de Botánica, 2016-03)Leguminosae is a family with high value of use for food, medicine, forage, ornamental and restoration ecology purposes. One obstacle for the use and management of many legume species is the presence of seeds with physical ... -
Seed dormancy QTL identification across a Sorghum bicolor segregating population
(2016)Pre-harvest sprouting (PHS) in Sorghum bicolor is one of the main constrains for its production in the central region of Argentina, as grain maturation often coincides with rainy or high environmental humidity conditions. ... -
Spontaneous Gene Flow between Cultivated and Naturalized Vicia villosa Roth Populations Increases the Physical Dormancy Seed in a Semiarid Agroecosystem
(MDPI, 2021-05)Hairy vetch (Vicia villosa Roth) is the second most cultivated vetch worldwide being used as a forage and cover crop. As it is not domesticated, it displays several wild traits including seed dormancy. The physical seed ... -
The roles of light and pericarp on seed dormancy and germination in feral Raphanus sativus (Brassicaceae)
(Wiley, 2019-08-19)The timing of seed germination may determine the success of a weed species in an agroecosystem, and its expression is modulated by environmental conditions, but also by seed physiology and anatomy. The aims of this study ... -
Variación en el nivel de dormición de la semilla en distintas variedades de la forrajera estival Panicum virgatum L.
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2012-08)Panicum virgatum L. es una especie C4 tolerante a condiciones de sequía, considerada como una alternativa al panorama forrajero de la Región Semiárida Pampeana. Sin embargo, las semillas presentan dormición, lo cual ocasiona ...
