Productividad de pasturas y producción de leche bovina bajo pastoreo de gramínea y gramínea + lotus uliginosus en mosquera , cundinamarca
(UNIVERSIDAD NACIONAL DE COLOMBIA, 2008)
En el presente estudio se determinó y evaluó la producción de biomasa aérea (g MS/m2), composición botánica, calidad nutricional, y producción y calidad de leche en dos tipos de pasturas para clima frío. El ensayo se realizó ...
Growth during recovery evidences the waterlogging tolerance of forage grasses
(CSIRO, 2017-07)
Waterlogging is a stress of increasing importance for pastures as a consequence of global climate change. We evaluated the impact of waterlogging on four forage grasses with alleged differential tolerance, emphasising not ...
Genetic diversity in a world germplasm collection of tall fescue
(Sociedade Brasileira de Genética, 2013-05)
Festuca arundinacea Schreb., commonly known as tall fescue, is a major forage crop in temperate regions. Recently, a molecular analysis of different accessions of a world germplasm collection of tall fescue has demonstrated ...
Soil ecosystem function under native and exotic plant assemblages as alternative states in successional grasslands
(Elsevier, 2012-11-14)
Old fields often become dominated by exotic plants establishing persistent community states. Ecosystem function in such novel plant assemblages may differ widely from that in the alternative, native-dominated counterparts. ...
Effects of systemic fungal endophytes on the performance of meadow fescue and tall fescue in mixtures with red clover
(Wiley, 2015-09)
A symbiosis between grasses and systemic fungal endophytes exists in both natural and agricultural grassland communities. Our objective was to examine the effects of systemic endophytes on the competitive ability of two ...
Epichloë endophytes alter inducible indirect defences in host grasses
(Public Library of Science, 2014-06)
Epichloë endophytes are common symbionts living asymptomatically in pooid grasses and may provide chemical defences against herbivorous insects. While the mechanisms underlying these fungal defences have been well studied, ...

Negative and positive interactions among plants: effect of competitors and litter on seedling emergence and growth of forest and grassland species
(Wiley, 2015-05)
Living plant neighbours, but also their dead aboveground remains (i.e. litter), may individually exert negative or positive effects on plant recruitment. Although living plants and litter co-occur in most ecosystems, few ...
Screening of biomass production of cultivated forage grasses in response to mycorrhizal symbiosis under nutritional deficit conditions
(Wiley, 2014-09)
Arbuscular mycorrhizal fungi (AMF) colonize the root systems of most natural grassland species and usually increase plant growth by enhancing nutrients provision. This effect on growth responses of cultivated forage grasses ...
