Influencia del estado de madurez a cosecha sobre la calidad de semillas de alfalfa (Medicago sativa L.)
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2011-12)La alfalfa (Medicago sativa L.) recién cosechada presenta dormición física debida a la dureza de sus tegumentos que puede afectar la producción de forraje en el primer año de implantación. Aunque se conoce que la temperatura ... -
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 ... -
Variabilidad espacial de fertilidad química del suelo en un diseño de bloques
(Sociedad Española de la Ciencia del Suelo, 2011)En la caracterización del estado inicial de un ensayo de larga duración bajo siembra directa, se plantea la hipótesis de que existen -en los horizontes superficiales- gradientes de fertilidad horizontal (interbloques) y ... -
Development and validation of a simulation model for hairy vetch (Vicia villosa Roth) self-regeneration under different crop rotations
(Elsevier, 2019-04)Hairy vetch (HV, Vicia villosa Roth) is a winter annual legume cultivated for pasture grazing, in crop rotations with cereal crops under semi-arid conditions. The inclusion of HV increases soil nitrogen, thus contributing ... -
Diversity of Auchenorrhyncha (Hemiptera: Cicadellidae: Delphacidae) associated with Vicia villosa in southern Buenos Aires province, Argentina
(2014-06)Among the Hemiptera, the Auchenorrhyncha are well known owing to their phytosanitary relevance since the group includes pathogen vector species able to damage commercial crops. Vicia villosa Roth (Fabaceae) is a fodder ... -
Transgene escape and persistence in an agroecosystem: the case of glyphosate-resistant Brassica rapa L. in central Argentina
(2018-03)Brassica rapa L. is an annual Brassicaceae species cultivated for oil and food production, whose wild form is a weed of crops worldwide. In temperate regions of South America and especially in the Argentine Pampas region, ... -
Exoferality in sunflower (Helianthus annuus L.): a case study of intraspecific/interbiotype interference promoted by human activity
(2013)Helianthus annuus subsp. annuus, a biotype of the same species of the domesticated sunflower H. annuus var. macrocarpus, is an emergent noxious weed in several regions of the world. The frequent hybridization that occurs ... -
Can achene selection in sunflower crop–wild hybrids by pre-dispersal seed predators hasten the return to phenotypically wild sunflowers
(2016-04)Bird attack is a serious limitation to sunflower yield in several regions of the world, but it could also cause selection. The wild Helianthus annuus, naturalized in several regions of the world, hybridizes with the crop ... -
Broad resistance to acetohydroxyacid-synthase-inhibiting herbicides in feral radish (Raphanus sativus L.) populations from Argentina
(2016-02)BACKGROUND: Soon after the commercial release of sunflower cultivars resistant to imidazolinone herbicides, several uncontrolled feral radish (Raphanus sativus L.) populations were found in south-eastern Buenos Aires, ... -
Cold stress tolerance during early growth stages of naturalized Helianthus petiolaris populations
(2016-07)In the last 10 years the sunflower crop area of Argentina has shifted towards the Southwest as a result of the expansion of soybean cultivation. Early sowings require greater tolerance to low temperatures in order to ... -
