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 ... -
Capacity and Intensity Indicators to evaluate the effect of different crop sequences and cover crops on soil physical quality of two different textured soils from Pampas Region
(Elsevier, 2021-11)Soil physical degradation is a current problem in Molisols of the Pampas Region under no-tillage (NT), that has been related to over-simplified agricultural systems with scarce or no rotations and long winter bare fallows. ... -
Junglerice (Echinochloa colonaL.) seedling emergence model as a tool to optimize pre-emergent herbicide application
(Italian Society for Agronomy, 2021-07)Junglerice (Echinochloa colona), one of the worst and most problematic weeds globally, causes significant economic losses due to yield loss and control cost increase. Taking into account that this weed emerges in approximately ... -
Analysis of molecular mobility in corn and quinoa flours through ¹H NMR and its relationship with water distribution, glass transition and enthalpy relaxation
(Elsevier, 2021-03)Solids-water interactions of corn and quinoa flours were evaluated through 1H NMR, DSC, and water sorption isotherms. Glass transition temperature (Tg), observed by DSC, was better distinguished through FID signals, and ... -
Phosphorus and nitrogen fractions during base flow conditions of a Pampean stream and their relationship with land use
(Asociación Argentina de Ecología, 2020-12)During the last decades, population growth and the associated intensification of anthropogenic activities (agriculture, industrialization and urbanization) increased nutrient inputs to Pampean lotic waterbodies. However, ... -
Comportamiento dinámico del peso del huevo en gallinas camperas discriminadas por indicadores productivos a la madurez sexual
(Facultad de Ciencias Veterinarias, Universidad Nacional de La Pampa, 2020-10-29)The effects on the dynamic pattern of egg weight of five traits at sexual maturity were characterized in Campero Casilda hens. When the first egg was laid, body weight, age (an indicator of sexual precocity), weight of ... -
Multi-parental QTL mapping of resistance to white spot of maize (Zea mays) in southern Brazil and relationship to QTLs of other foliar diseases
(Wiley, 2021-10)Maize white spot (MWS) is one of the most important foliar diseases in Brazil causing significant yield losses. Breeding genotypes with MWS resistance is the most sustainable alternative for managing such losses; however, ... -
Fertilizer vs. organic matter contributions to nitrogen leaching in cropping systems of the Pampas: 15N application in field lysimeters
(Springer, 2006-11-07)Nitrogen (N) export from soils to streams and groundwater under the intensifying cropping schemes of the Pampas is modest compared to intensively cultivated basins of Europe and North America; however, a slowNenrichment ... -
The herbage productivity of tall fescue in the Pampas region of Argentina is correlated to its ecological niche
(Wiley, 2016-09)Since its introduction in the 1950s, tall fescue has spread throughout the Pampas region of Argentina to become naturalized in much of this region. Its annual forage mass productivity shows significant differences among ... -
Caracterización de poblaciones nativas de maíz mediante análisis de procrustes generalizado y análisis factorial múltiple
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2012)El establecimiento de relaciones entre taxones es un paso esencial en el proceso de catalogación y evaluación del material conservado en un Banco de Germoplasma. Existen distintos métodos de evaluación en función del tipo ... -
Genomics-assisted breeding for quantitative disease resistances in small-grain cereals and maize
(MDPI, 2020-12-19)Generating genomics-driven knowledge opens a way to accelerate the resistance breeding process by family or population mapping and genomic selection. Important prerequisites are large populations that are genomically ... -
Characterization of maize populations in different environmental conditions by means of Three-Mode Principal Components Analysis
(Facultad de Agronomía e Ingeniería Forestal, Pontificia Universidad Católica de Chile, 2010-12)Characterization of 31 native populations of maize conserved at the germplasm bank of the INTA Pergamino Experimental Station, Argentina, was achieved by evaluating 10 quantitative attributes in two different environmental ... -
Heredabilidad, correlaciones genéticas, análisis de sendero e índices de selección en una población de girasol (Helianthus annuus) de la EEA INTA Pergamino
(Ediciones INTA, 2021-08)El primer paso en un programa de desarrollo de cultivares es formar una población con variabilidad genética para los caracteres de interés. La selección de progenies provenientes de poblaciones constituye una valiosa ... -
