      Las posibilidades de usar gramíneas para alimento del ganado están sujetas al conoci miento de sus características nutricionales. El objetivo del presente ensayo fue evaluar la degradabilidad ruminal en bovinos, de la ...

    • Diversity in apomictic populations of Paspalum simplex Morong 

      Brugnoli, Elsa Andrea; Urbani, Mario Hugo; Quarin, Camilo Luis; Zilli, Alex Leonel; Martínez, Eric Javier; Acuña, Carlos Alberto (Crop Science Soc Amer, 2014)
      Paspalum is considered a genetic model for studying the sources of genotypic variability and breeding techniques in apomictic plants. Pas­palum simplex is a warm-season forage grass that well represents the genus since it ...

    • Diversity in diploid, tetraploid and mixed diploid-tetraploid populations of paspalum simplex 

      Brugnoli, Elsa Andrea; Urbani, Mario Hugo; Quarin, Camilo Luis; Martínez, Eric Javier; Acuña, Carlos Alberto (Crop Science Society of America, 2013-07)
      The tetraploid cytotype of Paspalum simplex has a wide geographical distribution and reproduces by apomixis, while the diploid grows in a restricted area in northern Argentina and behaves as cross-pollinated. The objective ...

    • Efecto de la inoculación con rizobacterias sobre la micorrización, biomasa y contenido de fósforo de paspalum atratum cv camba FCA 

      Mango, Analía; Urbani, Mario Hugo; Iglesias, María Cándida (Universidad Nacional del Nordeste. Facultad de Ciencias Agrarias. Instituto Agrotécnico "Pedro M. Fuentes Godo", 2017-11-30)

    • Genetic relationship among paspalum species of the subgenus anachyris : taxonomic and evolutionary implications 

      Zilli, Alex Leonel; Hojsgaard, Diego Hernán; Brugnoli, Elsa Andrea; Acuña, Carlos Alberto; Honfi, Ana Isabel; Urbani, Mario Hugo; Quarin, Camilo Luis; Martínez, Eric Javier (Elsevier, 2014-10)
      Paspalum is one of the most important genera of the Poaceae family due to its large number of species and diversity. The subgenus Anachyris comprises six species mainly from South America grouped together by sharing rare ...

    • Genetic transfer from several apomictic tetraploid paspalum species to an elite group of sexual plants 

      Novo, Patricia Elda; Acuña, Carlos Alberto; Urbani, Mario Hugo; Galdeano, Florencia; Espinoza, Francisco; Quarin, Camilo Luis (Crop Science Society of America, 2020)
      Basic findings from classical genetic studies are available for exploiting apomixis in the breeding of several forage grass genera. Most Paspalum species are multi- ploid with a sexual diploid cytotype and conspecific ...

    • Hybridization and heterosis in the plicatula group of paspalum 

      Novo, Patricia Elda; Acuña, Carlos Alberto; Quarin, Camilo Luis; Urbani, Mario Hugo; Marcón, Florencia; Espinoza, Francisco (Springer, 2017)
      Most forage cultivars released for thegenus Paspalum belong to a section named Plicatula.The species of Plicatula are mostly apomictic andconsequently the genetic diversity is locked for theirgeneticimprovement. The ...

    • Inoculación con rizobacterias en paspalum atratum cv. cambá fca. Efecto sobre el crecimiento, producción de biomasa y micorrización 

      Mango, Analía (Universidad Nacional del Nordeste. Facultad de Ciencias Agrarias, 2019)
      Paspalum atratum cv Cambá FCA es una gramínea perenne de ciclo estival con alto potencial forrajero para el nordeste argentino. Los bajos contenidos de fósforo en los suelos de esta región pueden afectar el crecimiento y ...
