Plant species and defoliation effects on soil nitrogen mineralization in a semiarid rangeland of Argentina
(Springer, 2021-09)
The objective of this study was to evaluate the effects of moderate defoliation and grass species on soil nitrogen (N) mineralization in a semiarid grassland of northeastern Patagonia, Argentina. Studied species were Poa ...

The TTC-technique might not appropriately test the physiological stage of plant tissues
(Springer, 2015-07)
The 2,3,5triphenyltetrazolium chloride (TTC) technique has been used during decades to distin guish between dead and alive tissues of perennial grasses. This technique did not consider, however, that dormant (i.e., viable) ...
Communities of arbuscular mycorrhizal fungi associated with perennial grasses of different forage quality exposed to defoliation
(Academic Press Ltd - Elsevier Science Ltd, 2018-07)
Vegetation management practices, such as defoliation may alter the composition of plant communities and/orthe fungi-forming arbuscular mycorrhiza (AMF). We determined the species identity, density, frequency anddiversity ...
Total and structure colonization by arbuscular mycorrhizal fungi in native, perennial grasses of different forage quality exposed to defoliation
(Elsevier B.V., 2018-06)
Defoliation can compromise the quality and quantity of colonization by arbuscular mycorrhizal fungi (AMF), which contribute to vegetation persistence in semiarid rangelands. The effects of defoliation on total arbuscular ...
Descomposición y dinámica de nutrientes en el suelo debajo de especies de diferente preferencia animal en pastizales naturales del sudoeste bonaerense
(Centro de Recursos Naturales Renovables de la Zona Semiárida, 2015-07)
Poa ligularis (Pl), Nassella tenuis (Nt) y Amelichloa ambigua (Aa) son gramíneas perennes, abundantes en los pastizales naturales del sudoeste bonaerense. Las dos primeras especies son preferidas por el ganado y producen ...
