Linkage disequilibrium patterns, population structure and diversity analysis in a worldwide durum wheat collection including Argentinian genotypes
(BMC, 2021-04-05)Background: Durum wheat (Triticum turgidum L. ssp. durum Desf. Husn) is the main staple crop used to make pasta products worldwide. Under the current climate change scenarios, genetic variability within a crop plays a ... -
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 ... -
Linking farmers' management decision, demographic characteristics and perceptions of ecosystem services in the Southern Pampa of Argentina
(Elsevier, 2020-03-15)In the Pampean region of Argentina, uncultivated areas with spontaneous vegetation, such as the sierras (low hills), are important sites for nature conservation. In the last decades, the “agriculturization” process has ... -
Linoleic acid stimulates neutral lipid accumulation in lipid droplets of maturing bovine oocytes
(Elsevier, 2013-03-01)Linoleic acid (LA) is a polyunsaturated fatty acid present in high concentrations in bovine follicular fluid; when added to maturation culture media, it affects oocyte competence (depending on the type and concentration ... -

(Sociedad Argentina de Genética, 2020-09)El objetivo de este trabajo fue evaluar la respuesta a las inoculaciones con Phomopsis helianthi en capítulos de 8 líneas R de girasol (del programa de mejoramiento local) y de los cultivares Syn3970CL y Par1600CLPlus (de ... -
Llama (Lama glama) semen collection via thermo-electric artificial vagina: effect of seasonality and collection interval on ejaculate characteristics
(Elsevier, 2015-09-09)Adult male Llamas (Lama glama) (n = 6) were collected using a receptive female and a thermo-electric artificial vagina assembled with a polyethylene collection bag with the following objectives: (a) to develop a reliable ... -
Longitud de la vaina como determinante de la calidad de hojas de festuca arundinacea durante un período de rebrote
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-08)Se evaluó la calidad nutritiva de las láminas de rebrotes de Festuca arundinacea provenientes de dos tratamientos de corte de distinta altura de remanentes (40 mm y 100 mm). El experimento se realizó en 500 macetas al aire ... -
Los desafíos de la agricultura
(International Plant Nutrition Institute, 2016-04)Este libro es una ampliación de uno anterior denominado "La tecnología y la producción agrícola, el pasado y los actuales desafíos". Toma del mismo los temas relacionados con las innovaciones del pasado y los escenarios ... -
Lotus spp.: a Mediterranean genus with high environment and economic impact in the Salado River Basin (Argentina)
(Springer, 2024-05)This review has the principal objective in to hypothesise that the introduction of Lotus species could have significant benefits in constrained soils due their worldwide distribution. This idea is major based on results ... -
Lotus tenuis (Waldst. et Kit), estudio para un manejo con múltiples propósitos
(Ediciones INTA, 2020-12)El uso de cultivos con múltiples propósitos es una opción que permite obtener de un mismo sistema de producción diferentes servicios ecosistémicos. El objetivo del presente trabajo fue combinar fechas de corte en un cultivo ... -
Low temperature differentially affects tillering in spring and winter wheat in association with changes in plant carbon status
(Wiley, 2015-03)The higher tillering potential of winter wheat cultivars as compared to spring ones has been attributed to an earlier tillering onset in the former. Tillering in grasses is known to depend on temperature and light environment, ... -

Maize grain yield components and source-sink relationship as affected by the delay in sowing date
(Elsevier, 2016-11)Delaying maize (Zea mays L.) sowing date can diminish grain yields through reductions in the number, size and activity of growing grains (sink strength) and/or reductions in the assimilate supply (source capacity) to grains ... -
Maize leaf rolling and its response to drying soil and evaporative demand
(Wiley, 2023-05-31)Leaf rolling is an adaptive mechanism associated with water deficiencies; however, the physiological processes and environmental factors contributing to leaf rolling are not fully understood. The objective of this study ... -
Maize Physiological Responses to Heat Stress and Hormonal Plant Growth Regulators Related to Ethylene Metabolism
(2013-07)Hormonal plant growth regulators (HPGRs) have been evaluated in field grown maize (Zea mays L.), but never as a tool for prevention or mitigation of heat stress. We analyzed grain yield determination of maize crops exposed ... -
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 ... -
Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ... -
