Aporte de la fijación biológica de nitrógeno a la emisión de N2O desde el suelo con cultivo de soja = Contribution of biological nitrogen fixation to N2O emission from soil under soybean
(Asociación Argentina de la Ciencia del Suelo, 2015)El óxido nitroso (N2O) es el principal gas de efecto invernadero emitido desde el sector agrícola y su producción biológica en los suelos se genera por dos vías, la nitrificación y la desnitrificación. Recientemente el ... -
Comportamiento del carbono orgánico y las fracciones de fósforo en un kandiudult con distintos manejos de residuos forestales = Organic carbon and phosporus fractios in a kandiudult with different forestry residue managements
(Asociación Argentina de la Ciencia del Suelo, 2015)El objetivo de este trabajo fue evaluar los efectos de diferentes sistemas de manejo de residuos de cosecha en una plantación de Pinus taeda (L) sobre las distintas fracciones de fósforo (P) del suelo y el carbono orgánico ... -

Characterization of functional SSR markers in Prosopis alba and their transferability across Prosopis species
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (España), 2015)Aim of study: The aim of the study was to characterize functional microsatellite markers in Prosopis alba and examine the transferability to species from the Prosopis genus. Area of the study: samples were obtained from ... -
Down-regulation of catalase activity contributes to senescence induction in wheat leaves exposed to shading stress
(Springer, 2015-01)In shaded wheat (Triticum aestivum L.) leaves, the suppression of blue radiation (BR) triggers senescence. This phenomenon is correlated to an increase in oxidative stress symptoms and a decrease of catalase (CAT) activity, ... -
Estrategias de mitigación y adaptación al cambio climático en el sector agropecuario
(2015-02)El Cambio Climático es una alteración del estado del clima que puede ser identificado por cambios en la media o en la variabilidad de sus propiedades, y que persiste por un período extendido, típicamente décadas o más ... -
Effect of allelic variation at the Glu-3 / Gli-1 loci on breadmaking quality parameters in hexaploid wheat [Triticum aestivum L.]
(2015-03)Low molecular weight glutenin subunits (LMW-GS) encoded by the Glu-3 loci are known to contribute to wheat breadmaking quality. However, the specific effect of individual Glu-3 alleles is not well understood due to their ... -
Diversity and structure of bird and mammal communities in the Semiarid Chaco Region: response to agricultural practices and landscape alterations
(Imperial College London, Gran Bretaña, 2015-03)The conversion of land from natural environments to human-managed areas has been particularly pronounced in the semiarid Chaco Region. In this context, it is critical to understand the impacts that these major changes have ... -
