A fungal endophyte of a palatable grass affects preference of large herbivores
(2018-04)Temperate grasses frequently acquire resistance to herbivores through a symbiosis with epichloid fungi that produces alkaloids of variable deterrent effects. However, in those cases without apparent endophyte negative ... -
Analysis of genetic variability in in vitro regenerated buffelgrass plants through issr molecular markers = Análisis de variabilidad genética en plantas regeneradas in vitro de buffelgrass mediante marcadores moleculares issr
(Universidad Nacional de Cuyo, 2018)Genetic variability can be generated through in vitro culture via somaclonal variation. This tool can be potentially useful in a breeding program involving apomictic buffelgrass genotypes. The aim of this work was to ... -
Aporte del miscanthus x giganteus a la “iniciativa 4 por mil”
(Asociación Argentina de la Ciencia del Suelo, 2020-10)Actualmente, existe una gran incertidumbre acerca del futuro almacenamiento de carbono orgánico del suelo (COS) debido a que los sistemas de cultivo predominantes de la Pampa Ondulada no son ambientalmente sustentables. ... -
Assessing the genetic diversity of Panicum coloratum var. makarikariense using agro‐morphological traits and microsatellite‐based markers
(2015-11)Panicum coloratum var. makarikariense is a perennial C4 grass native to South Africa with relatively good forage production under limited‐resource conditions. Genetic characterisation and breeding efforts have been scant, ... -
Beneficial effects of Neotyphodium tembladerae and Neotyphodium pampeanum on a wild forage grass
(Wiley, 2012-09)Asexual, vertically transmitted fungal endophytes of the genus Neotyphodium are considered to enhance growth, stress resistance and competitiveness of agronomic grasses, but have been suggested to have neutral or deleterious ... -
Biomass production, arbuscular mycorrhizae and soil plant-available P under water stress in native perennial grasses
(CRC Press-Taylor & Francis, 2010-10)Precipitation determines vegetation type and species relative composition in plant communities [1]; in addition, it is a primary variable affecting soil water storage and availability. This availability is the most important ... -
Biomass, carbon and nutrient storage for dominant grasses of cold temperate steppe grasslands in southern Patagonia, Argentina
(Elsevier, 2010-01)We hypothesized that different dominant grasses species display contrasting nutrient accumulation, allocation and conservation strategies. Also, we expect a distinctive pattern of carbon and biomass partitioning according ... -
Breeding Tetraploid Paspalum simplex: Hybridization, Early Identification of Apomicts and Impact of Apomixis on Hybrid Performance
(Wiley, 2019)Apomictic grasses predominate among tropical forages, and specific breeding techniques are needed for their genetic improvement. The objectives of this study were (i) to generate hybrids by crossing tetraploid sexual and ... -
Capim annoni (Eragrosti plana) gramínea invasora que amenaza nuestros campos nativos.
(EEA Mercedes, INTA, 2021-04-05)Es una planta herbácea perenne, fibrosa, muy dura y rústica, fuertemente enraizada, generalmente de 40 a 60 cm de altura. La parte aérea y el sistema radicular son muy resistentes a la tracción mecánica, siendo difícil ... -
Cartografía de un nuevo Modelo de Estados y Transiciones de la Estepa Magallánica Seca en la Patagonia argentina
(Asociación Argentina de Ecología, 2021-08)Analizamos 103 censos de vegetación de la Estepa Magallánica Seca, un área de 12000 km2 de estepas graminosas semiáridas en el SE de la Patagonia. Los objetivos del presente trabajo fueron ampliar el relevamiento de ... -
Cattle dry manure fertilization increases forage yield of grass-legume mixtures, while maintaining the legume proportion and root-associated microbiota
(Wiley, 2024-03)The aim of this study was to find ways to improve the forage yield of grass-legume mixtures without compromising soil biodiversity. In Argentinean Patagonia, the effects of applying cattle dry manure (M) and urea (U) (0, ... -
Cebadillas (Bromus sp.)
(EEA Marcos Juárez, INTA, 2023-08)En la colección se encuentran las especies B. catharticus y B. auleticus (nativas) y B. lithobius, B. mango, B. coloratus, B. tunicatus y B. araucanus (endémicas; región andino-patagónica). -
Climatic niche shift in the amphitropical disjunct grass Trichloris crinita
(2018-06)Plant species disjunctions have attracted the interest of ecologists for decades. We investigated Trichloris crinita, a native C4 perennial grass with disjunct distribution between subtropical regions of North and South ... -
Coexistence of grasses and shrubs in Patagonian steppes. Norm or exception?
(Wiley, 2023-02-08)Community ecology’s central challenge is to define and corroborate theoretical frameworks that predict -at least in general terms- the composition of communities. The predictive power of a theory based on interspecific ... -
Collection and morphological characterization of Panicum coloratum L. in Argentina
(2013-06)Panicum coloratum (Poaceae) is a perennial grass native to South Africa, distributed all over the world, but poorly adopted by ranchers in Argentina. Adapted to a wide range of soil and climatic conditions, it constitutes ... -
Comportamiento de gramíneas megatermicas introducidas en condiciones de riego en el noreste patagónico

Curvas de crecimiento de forrajeras templadas irrigadas
(Asociación Latinoamericana de Producción Animal, 2001)Con el objetivo de construir y comparar las curvas de distribución estacional de forraje de 15 gramíneas y leguminosas se realizaron cuatro ensayos entre 1996 y 1999. Cada uno constó de dos repeticiones compuestas cada una ... -
Differential water-use strategies and drought resistance in Trichloris crinita plants from contrasting aridity origins
(2013-08)In arid environments, water availability is the main limiting factor for primary production, and it is expected that not only drought-resistance, but also plant strategies for soil water use will be under natural selection. ... -
