Assessment of phenotypic variability among EEA INTA Pergamino sunflower lines: Its relationship with the grain yield and oil content
(2021-05)The aims of the present study were to assess the phenotypic diversity among 221 sunflower accessions of INTA Pergamino Sunflower Breeding Program, to obtain discriminant functions that allow the classification of new ... -
Assessment of physiological races of Exserohilum turcicum isolates from maize in Argentina and Brazil
(Springer, 2021-02)Northern corn leaf blight (NCLB) is one of the most important diseases in maize worldwide. It is caused by the fungus Exserohilum turcicum, which exhibits a high genetic variability for virulence, and hence physiological ... -
Avances sobre el manejo de arvenses en la huerta agroecológica
(Ediciones INTA, 2023-06)En la agricultura convencional el barbecho químico es una práctica eficiente para contrarrestar el efecto de arvenses en el cultivo, aunque con riesgos de impacto ambiental. La agroecología propone prácticas de manejo ... -
Bovine autosomal recessive alpha-mannosidosis in an Aberdeen Angus herd from Argentina
(Wiley, 2023-08)An outbreak of α-mannosidosis in a bovine herd from Buenos Aires province is reported. Postmortem examination, histology, lectin histochemistry and electron microscopy were performed on five calves born with nervous signs. ... -
Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis
(Oxford University Press, 2022-03)The light attenuation process within a plant canopy defines energy capture and vertical distribution of light and nitrogen (N). The vertical light distribution can be quantitatively described with the extinction coefficient ... -
Cane molasses and oligofructose in the diet of laying hens improves the mineral content of eggs and meat
(Elsevier, 2022-06)Poultry-based foods contribute to human health due to their high nutrient value. Previously, it was shown that short-chain fatty acids (SCFAs) produced by in vitro intestinal fermentation of a molasses and oligofructose ... -
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. ... -
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 ... -
Carotenoid and color changes in traditionally flaked and extruded products
(Elsevier, 2017-08)The objective of this study was to evaluate the impact of process and formulation on individual carotenoid loss in traditionally prepared cornflakes and those prepared by extrusion. The first step in the traditional process ... -
Changes in number and weight of wheat and triticale grains to manipulation in source-sink relationship
(Hindawi, 2019-01)The source-sink ratio experimental manipulation has helped to define whether a crop is limited by source or sink or co-limited by both. There is no evidence in triticale of source-sink manipulations effects on yield and ... -
Changes of starch composition by postflowering environmental conditions in kernels of maize hybrids with different endosperm hardness
(2017-05)Starch composition of maize grains is of great importance when used in animal feed and many processing industries. Maize production involves hybrids with different kernel composition and hardness, sown at areas that range ... -
Characterization of junglerice: growth habit and morphological plasticity determined by population density
(Brazilian Weed Science Society, 2024-02)Fondo: Numerosos estudios han descrito la competitividad del arroz selvático ( Echinochloa colona ) frente a cultivos, pero su comportamiento en cuanto a la densidad de plantas como resultado de la competencia intraespecífica ... -
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 ... -
Classification of argentine maize landraces in heterotic groups
(Consiglio per la Ricerca in Agricoltura e l'Analisi dell'Economia Agraria, 2012)The genetic diversity of maize (Zea mays L) is a valuable and strategic natural resource that plays a key role in the breeding progress. However, exploitation of genetic variability from landraces has not reached a significant ... -
Climate impacts on crop yields in Central Argentina. Adaptation strategies
(2018-02)The Pampas is among the major agricultural regions in the world; a large proportion of Argentina crop production is originated in this region. The exportation of grain and oil crop represents more than 40% of the total ... -
Colour and surface fluorescence development and their relationship with Maillard reaction markers as influenced by structural changes during cornflakes production
(Elsevier, 2012-12)The aim of this work was to study colour and surface fluorescence development in relation to the chemical markers for the Maillard reaction at the cooking, flaking and toasting stages of cornflake production process. Colour ... -
Combining cover crops and low nitrogen fertilization improves soil supporting functions
(2019-07)Background and aims: Cover crops may restore soil functions lost with single summer crop sequences enhancing soil organic carbon and nitrogen (SOC and SON) stocks. We investigated the effect of cover crops and low nitrogen ... -
Combining pedigree and genomic information to improve prediction quality : an example in sorghum
(Springer, 2019-07)Selection based on genome-wide markers has become an active breeding strategy in crops. Genomic prediction models can make use of pedigree information to account for the residual polygenic effects not captured by markers. ... -
