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 ...
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. ...
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 ...
Anatomical traits, silica content and herbivory damage in leaves of invasive tree Ligustrum lucidum developed in novel and native ranges
(Elsevier Gmbh, 2019-09)
Ligustrum lucidum is an invasive tree in many regions, but scarce work analyzes its anatomical or eco-functional traits and its relation with herbivores, an important issue to be addressed by invaders in new areas. On the ...
Alternativas para a cinza de casca de arroz: uma revisão
(Universidade Federal de Santa MariaBrasilUFSMUFSM Cachoeira do Sul, 2021)
On the American continent, Brazil is the largest rice producer, Rio Grande do Sul state is responsible for 70% of this production. In the production and processing of rice, among the residues generated, the husk is the ...
Silicon fertilization increases gas-exchange and biomass by silicophytolith deposition in the leaves of contrasting drought-tolerant sugarcane cultivars under well-watered conditions
(2021-09-01)
Purpose: Silicon (Si) fertilization provides benefits to sugarcane. However, information remain scarce about the relationship between Si fertilization, gas exchange responses, biomass and silicophytolith accumulation in ...
