Physiological and genetic characterization of wheat lines sharply differing in sodium accumulation
(Sociedad Argentina de Fisiología Vegetal, 2023-10-01)Improving nutrient use efficiency is an important objective in modern breeding programs. Our group attempts to elucidate the components that contribute to greater efficiencies of potassium (K) acquisition and utilization ... -
¿Qué ocurrió con la eficiencia agrícola en la región pampeana argentina entre 1988 y 2002?
(2015-05-21)Este trabajo tiene como objetivo medir diferencias en eficiencia técnica de partidos/departamentos de la región pampeana que producen los cuatro cultivos principales maíz, girasol, trigo y soja. Para ello se estimaron ... -
Reaction of South American wheat genotypes to wheat streak mosaic virus
(Springer, 2018-08)Wheat streak mosaic virus (WSMV) is an emerging virus in South America that threatens cereal production. Genetic resistance is used in other regions as an effective strategy for management of this disease. The susceptibility ... -
Regulation of Zn and Fe transporters by the GPC1gene during early wheat monocarpic senescence
(2014-12)Background; During wheat senescence, leaf components are degraded in a coordinated manner, releasing amino acids and micronutrients which are subsequently transported to the developing grain. We have previously shown that ... -
Relación clima y virosis en los cultivos de trigo y maíz
(Universidad Nacional del Noroeste de la Provincia de Buenos Aires -UNNOBA, 2022-10-19)Numerosos procesos infecciosos de las enfermedades de las plantas están influenciados por el clima, en particular con variables como la temperatura, la precipitación y el viento. Además del efecto del clima sobre los ... -
Relevamiento de gastos en investigación y obtención de cultivares de trigo y soja en el INTA
(Instituto de Economía y Sociología, INTA, 2002-05)Este trabajo forma parte del Proyecto Foncyt PICT 3524, “Economía de la Investigación Agrícola: Derrames de Conocimiento, Economías de Escala y de Diversidad en la Producción de Tecnología en Trigo y Soja”. Sus objetivos ... -
Response to heat stress and glutenins allelic variation effects on quality traits in durum wheat
(Wiley, 2024-01-16)In the context of climate change, high temperature is one of the main abiotic stresses hampering durum wheat production. Through the characterization of an international panel of 271 genotypes, this study investigates the ... -
Responses of Rhopalosiphum padi (L.) (Homoptera: Aphididae) on different wheat cultivars under laboratory conditions
(2017-06)Bird cherry-oat aphid, Rhopalosiphum padi (L.), a polyphagous species with a worldwide distribution, is an important pest of wheat as well as the main vector of barley yellow dwarf virus. The development, survivorship, and ... -
Respuesta biológica y poblacional de Schizaphis graminum (Rond.) (Hemiptera: Aphididae) sobre ocho cultivares de trigo (Triticum aestivum L.) en condiciones de laboratorio
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-12)El áfido Schizaphis graminum (Rond.) es una plaga clave en cultivos de cereales como el trigo en la Argentina. El objetivo de este trabajo fue analizar la respuesta bio-demográfica del áfido sobre los cultivares de trigo ... -
