El manejo agrícola puede afectar la comunidad de las ... -
Uso de germoplasma exótico para el mejoramiento de la resistencia genética a factores bióticos que afectan el cultivo de soja en Argentina
(2014)En Argentina la ganancia genética lograda en soja entre los años 1980 y 2000 fue de 14,3 Kg/ha/año, lo que representa el 62 % del incremento en rendimiento logrado en este período. Esto fue posible debido al uso de pocos ... -
IgY against enterotoxigenic Escherichia coli administered by hydrogel-carbon nanotubes composites to prevent neonatal diarrhoea in experimentally challenged piglets
(2016-06-14)In previous studies, the applicability of polymeric hydrogels for the protection of egg yolk immunoglobulin (IgY) against simulated gastric conditions was established. Thereafter, the performance of the hydrogels was ... -
Identification and characterization of Rht25, a locus on chromosome arm 6AS affecting wheat plant height, heading time, and spike development
(2018)Understanding genes regulating wheat plant height is important to optimize harvest index and maximize grain yield. In modern wheat varieties grown under high-input conditions, the gibberellin-insensitive semi-dwarfing ... -
Spatial and temporal plant-to-plant variability effects on soybean yield
(2018-08)Plant density and row spacing are management practices that farmers use to maximize soybean (Glycine max (L.) Merr.) yield. Other canopy aspects related to seedling establishment like spatial (spacing among plants) and ... -
Nanocomposites based on pH-sensitive hydrogels and chitosan decorated carbon nanotubes with antibacterial properties
(2018-09-01)The present work aimed to study the properties of a novel nanocomposite with promising biomedical applications. Nanocomposites were prepared by the addition of different concentrations of chitosan decorated carbon nanotubes ... -
Characterization of Actinobacillus pleuropneumoniae field strains antigenically related to the 3-6-8-15 group from diseased pigs in Japan and Argentina = Caracterización de cepas de Actinobacillus pleuropneumoniae antigénicamente relacionados al grupo 3-6-8-15 obtenidos de cerdos infectados naturalmente en Japón y Argentina
(2018-03)The objectives of this study were to determine the serovar of a collection of Actinobacillus pleuropneumoniae strains within the 3-6-8-15 cross-reacting group and to analyze their phenotypic and genetic properties. Based ... -
Comportamiento genético de diversos genotipos de trigo frente a Fusarium graminearum = Genetic behavior of different wheat genotypes against Fusarium graminearum
(2016-05)Fusarium graminearum es el principal agente causal de fusariosis de la espiga (FET) de trigo en Argentina, disminuye el rendimiento, reduce la calidad del grano y su uso final, y libera micotoxinas. El objetivo de este ... -
Molecular and mycotoxin characterization of Fusarium graminearum isolates obtained from wheat at a single field in Argentina
(2016-01)Fusarium graminearum is the primary causal agent of Fusarium head blight of wheat in Argentina. This disease affects yield losses and quality of grains, reducing the wheat end-use, also causing mycotoxin contamination. In ... -
An integrated dual strategy to control Fusarium graminearum sensu stricto by the biocontrol agent Streptomyces sp. RC 87B under field conditions. Reprint
