El rol de las biotécnicas de reproducción asistida en la transmisión del virus de la diarrea viral bovina
(Facultad de Ciencias Veterinarias, Universidad de Buenos Aires, 2015-06)Las biotécnicas de reproducción asistida han adquirido importancia comercial en los últimos años. Asociado a estas técnicas surge el interrogante sobre su rol en la posible transmisión de agentes infecciosos vía semen y ... -
Role of proteases in the response of plants to drought
(Elsevier, 2021-09-30)Plants are sessile organisms that, to survive they develop response mechanisms under water deficit conditions. Plant proteases play an essential role in a diversity of biological processes, among them tolerance to drought ... -
Rolling Pampas agroecosystem: which landscape attributes are relevant for determining bird distributions?
(Springer, 2014-12)Background: Agricultural intensification is among the main factors affecting biodiversity. The Rolling Pampas of Argentina have undergone through a process of landscape transformation and agricultural intensification that ... -
Scarites anthracinus (Coleoptera: Carabidae): bioindicador del efecto tóxico de clorpirifos y Cipermetrina
(2015-06)Los carábidos predadores se concentran en la superficie del suelo y se encuentran expuestos a los efectos adversos a la aplicación de los insecticidas. Por lo tanto, el objetivo de este trabajo fue evaluar el efecto de ... -
Secuencia de cultivos con predominio de soja: efecto sobre indicadores de calidad física del suelo.
(Asociación Argentina de la Ciencia del Suelo, 2020-12)El aumento en la frecuencia del cultivo de soja y de su monocultivo puede provocar disminuciones en la materia orgánica del suelo (MO) y afectar sus propiedades físicas. Sin embargo, prácticas de manejo como la fertilización, ... -
Selection and hybridization shaped the rapid spread of African honey bee ancestry in the Americas
(Public Library of Science, 2020-10)Recent biological invasions offer ‘natural’ laboratories to understand the genetics and ecology of adaptation, hybridization, and range limits. One of the most impressive and well-documented biological invasions of the ... -
Selection for high spike fertility index increases genetic progress in grain yield and stability in bread wheat
(Springer Netherlands, 2018-07-18)Spike fertility index (SF) has been proposed as a promising trait to be used as a selection criterion in wheat breeding programs aimed at increasing grain yield, but no actual evidence of its successful application has ... -
Seminal plasma proteins interacting with sperm surface revert capacitation indicators in frozen-thawed ram sperm
(Elsevier, 2016-10)This study was conducted to evaluate the effects of interacting seminal plasma proteins (iSPP) obtained by AV or EE on frozen-thawed ram sperm in order to test the hypothesis whether this fraction could be sufficient to ... -
Shoot- and tuber-based critical nitrogen dilution curves for the prediction of the N status in potato
(Elsevier, 2020-09)Critical nitrogen (N) dilution curves describe the critical N concentration in plant tissues during crop growth and they are used to estimate the N nutriton status of whole plants in potato. Little is known, however, about ... -
Short- and long-term responses to seasonal drought in ponderosa pines growing at different plantation densities in Patagonia, South America
(2012-12)Trees drought responses could be developed in the short- or in the long-term, aiming at sustaining carbon fixation and water use efficiency (WUE). The objective of this study was to examine short- and long-term adjustments ... -
Silicophytoliths from a Pampean native tree community (Celtis ehrenbergiana community) and their representation in the soil assemblage
(Elsevier, 2018-06)Plant phytolith production and their incorporation into soil assemblages has been studied by diverse authors indifferent regions of theworld,mainly in the Northern Hemisphere and Africa. However, these types of studies ... -
Silo-bag system for storage of grains, seeds and by-products: A review and research agenda
(Elsevier, 2022-12)Silo-bags (grain bag, sausage bag or silo bolsa) have been used for storing grains in Argentina for more than 25 years, and are now fully integrated in the grain postharvest system at different levels with important economic ... -
Sistemas de cultivo alternativos desarrollados por productores en el sudeste de la provincia de Buenos Aires
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-10-21)El proceso de expansión de la soja (denominado sojización) en la pampa argentina ha tenido como consecuencia la especialización de numerosas explotaciones agrícolas en el cultivo de soja. Sin embargo, muchos actores del ... -
Situación de las virosis del cultivo de papa en el Sudeste Bonaerense
(Ediciones INTA, 2022-04)En el sudeste de la provincia de Buenos Aires se encuentra la principal región productora de papa de la Argentina. La papa que se produce tiene tres destinos: el mercado fresco, la industria y la producción de semilla, la ... -
Slaughter weight, sex and age effects on beef shear force and tenderness
(Elsevier, 2014-05)In Argentina, beef cattle prices decrease as slaughter weight increases regardless of animal age or carcass maturity, and this decrease is significantly greater in heifers (15%) than in steers (5%). The objectives of the ... -
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ... -
Soil organic carbon changes simulated with the AMG model in a high-organic-matter Mollisol
(Sociedad Española de la Ciencia del Suelo, 2016)Soil organic carbon (SOC) management requires a precise knowledge of how it is affected by soil use. Simulation models could help for this purpose. The AMG model is simple, requires information that is easily available, ... -
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley, 2020-01)Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ... -
