Vigor inicial de variedades de trigo y su relación con la capacidad supresiva de malezas
(Ediciones INTA, 2018-04)El uso de la capacidad supresiva de diferentes variedades de trigo es una alternativa para el manejo de malezas debido a la capacidad para interferir en el crecimiento de las mismas. La materia seca de las láminas foliares ... -
Volatile compounds released by maize grains and silks in response to infection by Fusarium verticillioides and its association with pathogen resistance
(2016)Many plants respond to fungal infections by producing and/or emitting a specific blend of oxylipins, some of them through the lipoxygenase (LOX) pathway. In vitro bioassays revealed that volatiles from silks and grains of ... -
Volatile metabolite profiling reveals the changes in the volatile compounds of new spontaneously generated loquat cultivars
(2017-10)In recent years, the advantageous traits of three new loquat cultivars have drawn the attention of breeders and growers. All three have spontaneously arisen from the ‘Algerie’ cultivar: the new ‘Xirlero’ cultivar is a bud ... -
Water and nitrate exchange between cultivated ecosystems and groundwater in the Rolling Pampas
(Elsevier, 2009-12)Understanding nitrogen (N) exchange between cultivated ecosystems and groundwater becomes crucial in the Rolling Pampas where high and variable water table levels are accompanied by increasing N-fertilization rates. Field ... -
Water and radiation use efficiencies in maize: breeding effects on single-cross Argentine hybrids released between 1980 and 2012
(Elsevier, 2019-11)Water deficit has been signaled as an important determinant of grain yield (GY) gaps between potential and actual GYs. Breeding for improved water as well as solar radiation productivities is a sustainable means to reduce ... -
What to Expect as Corn Yields Face a Third Straight La Niña
(University of Illinois, 2022-07-11)Meteorologists are forecasting a third consecutive year of La Niña. The occurrence of two successive La Niña winters in the Northern Hemisphere is common, however, having three in a row is relatively rare. A triple La Niña ... -
Wheat Outlook After Five Months of War in Ukraine
(University of Illinois, 2022-08-01)Even with the projection of increased wheat production in some countries, the world harvest is expected to be a little smaller as a result of effects of the war in Ukraine. Global production for the marketing year 2022/2023 ... -
Wheat Ppd-1 allelic combination modulates photoperiod sensitivity
(Sociedad Argentina de Fisiología Vegetal, 2018-11)ABSTRACT: a model linking Ppd-1 allelic composition to photoperiod response curve would allow replacing expensive and time consuming phenologic trials. In Ppd-1 near isogenic lines grown under different photoperiods we ... -
Wheat pre-anthesis development as affected by photoperiod sensitivity genes (Ppd-1) under contrasting photoperiods
(2018-01)Fine tuning wheat phenology is of paramount importance for adaptation. A better understanding of how genetic constitution modulates the developmental responses during pre-anthesis phases would help to maintain or even ... -
Wheat yield progress and stability during the last five decades in Argentina
(Elsevier, 2021-07)Improvement of grain yield (GY) at farm level, which is closely related to GY potential, seems to be the main alternative to increase wheat (Triticum aestivum L) production. The aim of current research was to assess the ... -
Wood structure, xylem functionality and growth of six Salix clones in two sites with different environmental stress in Argentina
(Sociedade de Investigações Florestais, 2018)The aims of the study were to evaluate the effects of abiotic stress (plantation site) and genotype (clone) on the wood anatomy and density of six Salix (willow) clones at three ages (2, 7, and 12 years), and the impact ... -
Wood waste characterization for composting
(ISHS, 2009)Use of composted wood wastes has beneficial effects on soil physical and chemical conditions and on crop productivity. This paper includes compositional data from thirteen different wood industry wastes, including bark, ... -
XVIII Reunión Anual de Forrajeras : festuca alta, distribución, utilización y mejoramiento
(Ediciones INTA, 2018-11)La ganadería se encuentra atravesando un proceso de expansión debido a mejoras en aspectos económicos y con muy buenas perspectivas por la apertura de nuevos mercados internacionales. Adicionalmente, existe posibilidades ... -
Yerba de bugre (Lonchocarpus nitidus)
(EEA San Pedro, INTA, 2022)Elegir plantas nativas para el arbolado urbano, cortinas forestales, montes de abrigo, forestación de rutas y el armado de parques es una opción valiosa en tanto son especies originarias del ecosistema y por lo tanto se ... -
Yield determinants, root distribution and soil water uptake in maize (Zea mays) hybrids differing in canopy senescence under post-silking drought
(CSIRO Publishing, 2021-05)Delayed canopy senescence or ‘stay-green’ (SG) trait in maize (Zea mays L.) could improve drought tolerance. Two field trials comparing four to six maize hybrids with different senescence rate were carried out at Buenos ... -
Yield stability and phenotypic plasticity of Populus spp. clones growing in environmental gradients: I-yield stability under field conditions
(Elsevier, 2020-05)Populus species have been extensively cultivated in different regions around the world due to their growth performance, easy vegetative propagation and wood properties (for lumber, pulp, fiberboard and plywood). Stability ... -
Zinc y boro en la producción de trigo
(AER 25 de Mayo, INTA, 2021-05)En la región Pampeana argentina, existen estudios desde hace más de 20 años que muestran la disminución de la concentración edáfica de zinc (Zn) y boro (B) atribuido a los cultivos (Panigatti, 1975; Andriulo et al., 1996). ... -
Zinc y microorganismos : una ayuda para el trigo
(AER 9 de Julio, EEA Pergamino, INTA, 2020-04)La provisión de nutrientes a los cultivos extensivos es una práctica ampliamente generalizada en la región pampeana. Lamentablemente la tasa de aporte que se realiza está en promedio, en un 50 % de lo que se exporta con ...
