Breeding Tetraploid Paspalum simplex: Hybridization, Early Identification of Apomicts and Impact of Apomixis on Hybrid Performance
Brugnoli, Elsa Andrea; Martinez, Eric Javier; Ferrari Usandizaga, Silvana Consuelo; Zili, Alex Leonel; Urbani, Mario; Acuña, Carlos Alberto (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 ... -
Calidad forrajera de los componentes morfológicos en leguminosas herbáceas nativas del norte de Santa Fe = Nutritive quality of morphological components in three native herbaceous legumes from northern Santa Fe
Riva De Neyra, Leonardo Atilio; Ferrari Usandizaga, Silvana Consuelo; Cracogna, Mariano Federico; Castro, Cesar German (Asociación Argentina de Producción Animal (AAPA), 2025-09)En el norte de Sta. Fe, la ganadería extensiva se basa principalmente en el aprovechamiento de pastizales naturales. No obstante, la producción forrajera se ve limitada por la salinidad del suelo y la alternancia de ... -
Genetic and morphological characterization of Acroceras macrum Stapf
Ferrari Usandizaga, Silvana Consuelo; Brugnoli, Elsa Andrea; Weiss, Alejandra I.; Zilli, Alex Leonel; Schedler, Mara; Pagano, Elba Maria; Martínez, Eric Javier; Acuña, Carlos Alberto (Wiley, 2015-12)Acroceras macrum is a warm‐season grass used for pastures, and it has high nutritive value. The scarce genetic and reproductive information about this grass is limiting its breeding for forage. The objective of this research ... -
Heterosis on morphological, reproductive and productive behavior of Acroceras macrum Stapf hybrids
Ferrari Usandizaga, Silvana Consuelo; Brugnoli, Elsa Andrea; Maidana, Carlos Emilio; Martinez, Eric Javier; Acuña, Carlos Alberto (Springer, 2024-08)Acroceras macrum, a forage grass from Africa, offers potential for enhancing cattle production in subtropical flood-prone regions. Despite its use in Northeast Argentina since the 1980s, the lack of available fertile seeds ... -
Mode of Reproduction and Meiotic Chromosome Behavior in Acroceras macrum
Ferrari Usandizaga, Silvana Consuelo; Martínez, Eric Javier; Schedler, Mara; Honfi, Ana I.; Acuña, Carlos Alberto (Wiley, 2020-01)Acroceras macrum Stapf is a high-quality C3 grass species adapted to the subtropics. It is a valuable forage resource in frequently flooded environments. The objectives were to analyze the type of polyploidy, mode of ... -
Nile grass (Acroceras macrum) for Argentinean waterlogged soils
Ferrari Usandizaga, Silvana Consuelo (CGIAR GeneBank PlatForm, 2018-06)Acroceras macrum (Nile grass) is a forage grass native to sub-Saharan Africa, and recommended for its good adaptation to wet soils with poor drainage and waterlogging tendency of NE Argentina (NEA). Its greatest ... -
Sistemas genéticos y diversidad en Acroceras macrum Stapf
Ferrari Usandizaga, Silvana Consuelo (Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2015)Acroceras macrum es una especie C3 perenne originaria de regiones húmedas, tropicales y subtropicales, de África. Sus destacables propiedades nutricionales se traducen en producción de carne, y su excelente adaptación a ... -
Supplementary data set corresponding to the manuscript "Can management sustainably improve the productivity of grazed grasslands?" (ASDE-D-24-01382) [Conjunto de datos]
Gandara, Luis; Pereira, Maria Mercedes; Ferrari Usandizaga, Silvana Consuelo (Estación Experimental Agropecuaria Corrientes, INTA, 2024)This table contains information regarding the evolution of the botanical composition of a subtropical grassland under grazing management that fits the pasture growth curve. Four treatments were compared: high grazing ... -
Supplementary dataset to the article "Sustainability of Pasture Species Diversity in Forage Allowance-Based Stocking Methods in Subtropical Grasslands of Northeast Argentina" [Conjunto de datos]
Gandara, Luis; Ferrari Usandizaga, Silvana Consuelo; Pereira, Maria Mercedes; Riva De Neyra, Leonardo Atilio (Estación Experimental Agropecuaria Corrientes, INTA, 2025-09-29)This dataset supports ecological and agronomic analyses of species dynamics, forage quality, and functional responses to grazing and mowing. It was used for meta-analysis, modeling, and comparative studies in pasture ecology.
