Root silicification of grasses and crops from the Pampean region and its relevance to silica and silicophytolith content of soils
(Springer, 2019-11)
Aims: Silicophytoliths contribute to the pool of amorphous silica that is incorporated into the soils acting as intermediary in the biogeochemical cycle of silicon. Most studies focus their attention in the production of ...
Silicification of the adaxial epidermis of leaves of a panicoid grass in relation to leaf position and section and environmental conditions
(Wiley Blackwell Publishing, Inc, 2012-07)
Many studies relate silica content in plants with internal or external factors; however, few works analyse the effect of these factors on the silicification of different cell types. In this study, we examined the effect ...
The seasonal and inter-annual patterns of biomass accumulation and crude protein in kleingrass (Panicum coloratum) in the semiarid Pampean region of Argentina
(Pontificia Universidad Católica de Chile. Facultad de Agronomía e Ingeniería Forestal, 2011)
Leaf and culm silicification of Pampas grass (Cortaderia selloana) developed on different soils from Pampean region, Argentina
(Csiro Publishing, 2016-12-12)
Amorphous silica accumulation in grasses is widely described in numerous species; however, work done in relation to the factors affecting this accumulation in the tissues and different type of cells, is still incipient. ...
Interrelations of vegetal cover, silicophytolith content and pedogenesisof Typical Argiudolls of the Pampean Plain, Argentina
(Elsevier Science, 2008-12)
Knowledge of the origin, evolution and weathering of Pampean soils is still limited. There are few prior studies of silicophytoliths, even though they could be important pedogenetic indicators that provide information about ...
Silica biogeochemical cycle in temperate ecosystems of the Pampean Plain, Argentina
(Pergamon-Elsevier Science Ltd, 2015-11)
Silicophytoliths were produced in the plant communities of the Pampean Plain during the Quaternary. The biogeochemistry of silicon is scarcely known in continental environments of Argentina. The aim of this work is to ...
Geographical distribution and habitat characterization of Poa schizantha (Poaceae), a narrow endemic of the coastal sand dunes of the southern Pampas, Argentina
(Wiley Blackwell Publishing, Inc, 2020-10-18)
Poa schizantha is a dioecious, psammophilous grass endemic to Atlantic coastal dunes in Argentina. We quantified the distribution area of this rare endemic species and characterized its habitat in the southern Pampas region. ...
Seasonality of feral horse grazing and invasion of Pinus halepensis in grasslands of the Austral Pampean Mountains (Argentina): management considerations
(Springer, 2020-06-28)
The introduction of domestic ungulates has altered the natural grazing regime, promoting the invasion of exotic woody plants being seasonality or stoking season one of the key factors regulating the grazing regime. The ...
