Palaeoenvironmental use of silicophytoliths in soils and palaeosols associated with Holocene volcanic ash deposits in north-western Argentina
(Pergamon-Elsevier Science Ltd, 2019-07)
We compare the silicophytolith record of current soils and Holocene palaeosols from two sedimentary sequences in a region between the Chaco-Pampean Plain and the Puna (Tolombón section in Santa María Valley, and Tafí del ...
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 ...
Amorphous silica biomineralizations in Polytrichum strictum Menzies ex Brid. (Bryophyta)
(Maney Publishing, 2013-06)
In this study, the presence of amorphous silica biomineralizations (silicophytoliths) in individuals of Polytrichum strictum collected from Tierra del Fuego, Argentina was analysed. Gametophyte and sporophyte samples were ...
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. ...
Late Quaternary vegetation history based on phytolith records in the eastern Chaco (Argentina)
(Pergamon-Elsevier Science Ltd, 2019-02)
The Chaco plain is a sedimentary basin filled by alluvial fans repeatedly generated by large rivers during the late Quaternary under diverse climatic conditions. The Eastern Chaco is characterized by semi-deciduous forests ...
Effect of silicate fertilizers on wheat and soil properties in Southeastern Buenos Aires province, Argentina. A preliminary study
(Elsevier Science, 2019-12)
Silicon is a major component in soils and is essential for the development of certain crops that produce silicophytoliths. Although there are studies about the effect of silicate fertilizers, there is no research in soils ...
Silicon fertilization increases gas-exchange and biomass by silicophytolith deposition in the leaves of contrasting drought-tolerant sugarcane cultivars under well-watered conditions
(Springer, 2021-07)
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 ...
Early silicification of leaves and roots of seedlings of a panicoid grass grown under different conditions: anatomical relation and structural role
(Wiley Blackwell Publishing, Inc, 2016-11)
Grasses accumulate high amounts of silica deposits in tissues of all their organs, especially at mature stage. However, when and under which conditions do grass seedlings begin to produce these silica deposits and their ...
