Recent progress in bovine In vitro‐derived embryo cryotolerance: impact of In vitro culture systems, advances in cryopreservation and future considerations
(Wiley, 2020-03-07)Cryopreservation of in vitro‐derived bovine embryos is a crucial step for the widespread reproduction and conservation of valuable high merit animals. Given the current popularity of bovine in vitro embryo production (IVP), ... -
Maize prolificacy: a source of reproductive plasticity that contributes to yield stability when plant population varies in drought-prone environments
(Elsevier, 2020-02)Reproductive plasticity, the ability of the plant to maintain the ratio between available resources and grain yield should be a useful trait to maintain the coupling between yield and resource availability under low-density ... -
Glyphosate and nutrient retention in preferential flow pathways
(Asociación Argentina de Ecología, 2019-12)Riparian vegetation strips (RVS) reduce surface runoff volume and retain sediments, pesticides and nutrients that are transported across them from adjacent crop-fields (CF). The ability of these strips to retain glyphosate ... -
Efecto de sistemas de labranza contrastantes sobre algunas propiedades de un molisol de Tres Arroyos bajo distintos usos previos
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2012)El proceso de "agriculturización" se define como el uso creciente y continuo de tierras para cultivos agrícolas en lugar de usos ganaderos o mixtos. El objetivo del trabajo fue evaluar el efecto de diez años de ... -
Are there different vigilance strategies between types of social units in Lama guanicoe?
(Elsevier, 2019-10)Group vigilance is a cooperative behaviour in social species that reduces individual risk of predation. Lama guanicoe is a social species of camelid performing cooperative vigilance, but little is known about the vigilance ... -
Dynamics of glyphosate resistance in Lolium perenne: pollen-mediated gene flow under field conditions in Argentina
(MDPI, 2018-11)The genus Lolium has shown a high tendency to evolve resistance to herbicides. Considering the high level of allogamy of L. perenne and the importance of the wind as an agent for pollen dispersion, the aim of this work was ... -
Efecto del glifosato sobre el crecimiento y acumulación de azúcares libres en dos biotipos de lolium perenne de distinta sensibilidad al herbicida = Glyphosate effects on the growth and free sugar accumulation of two lolium perenn e biotypes with different herbicide sensitivity
(Sociedade Brasileira da Ciência das Plantas Daninhas, 2012-03)El movimiento sistémico del glifosato está determinado por el transporte de fotoasimilados. A su vez, la capacidad de un destino de consumir los asimilados está condicionada por su actividad metabólica. Pese a su importancia, ... -
Grain yield, nutrient content and lipid profile of oat genotypes grown in a semiarid environment
(Elsevier, 2010-03-03)The objective was to evaluate oat cultivars for grain yield and quality in two years of different climatic conditions. Cultivars were chosen for forage yield, pest resistance or environmental stress tolerance. The study, ... -
Linking diet quality and energy demand in free‐living guanacos: an eco‐physiological innovative approach
(Wiley, 2019-04-18)In adaptive terms, animals are subject to challenges imposed by their environment. To address physiological patterns in wild mammals, the non‐invasive study of glucocorticoid hormones has become the main approach through ... -
Nueva variedad de trigo (Triticum aestivum L.) panadero: ‘MS INTA BONAERENSE 514’
(Universidad de Concepción, Chile, 2016)La nueva variedad de trigo (Triticum aestivum L.) MS INTA BONAERENSE 514 (MS INTA BON 514) es una variedad de trigo rojo panadero de crecimiento primaveral, designada en la estación experimental como W08033, desarrollada ... -
Growth promotion of rapeseed (Brassica napus) associated with the inoculation of phosphate solubilizing bacteria
(2018-09-01)Inoculation of microorganisms to improve crop yields and minimize the use of chemical fertilizers is a promising sustainable strategy. The objective of this study was to isolate and identify bacteria from the rhizosphere ... -
Assessment of bacterial inoculant formulated with Paraburkholderia tropica to enhance wheat productivity
(2018-06)Paraburkholderia tropica is an endophytic nitrogen-fixing bacterium isolated from the rhizosphere, rhizoplane, and internal tissues of sugarcane and corn plants in different geographical regions. Other plant-growth-promoting ... -
Effect of previous cropping of rapeseed (Brassica napus L.) on soybean (Glycine max) root mycorrhization, nodulation, and plant growth
(2016-10)Arbuscular mycorrhizal fungi (AMF) improve the uptake of immobile mineral nutrients such as phosphate, thereby enhancing the growth of most plants. However, plants belonging to the Brassicaceae family such as rapeseed ... -
Glyphosate effects on gas exchange and chlorophyll fluorescence responses of two Lolium perenne L. biotypes with differential herbicide sensitivity
(2012-08)Despite the extensive use of glyphosate, how it alters the physiology and metabolism of plants is still unclear. Photosynthesis is not regarded to be a primary inhibitory target of glyphosate, but it has been reported to ... -
Carbono orgánico del suelo bajo sistemas de cultivo contrastantes y su relación con la capacidad de proveer nitrógeno
(2017)Los contenidos de carbono (C) orgánico total (COT) y particulado (COP) del suelo disminuyen con los años bajo agricultura y su variación afecta muchos procesos edáficos que determinan la productividad (e.g. la provisión ... -
