The effects of chemical composition and distribution on the preservation of phytolith morphology

Applied Physics A, 2013
Different types of phytolith even when coming from the same plant react to high temperatures in different ways. To understand the behavior of phytoliths upon heating, we examined composition and distribution of some elements within different phytolith types using SEM-EDS and synchrotron radiation μ-X-ray fluorescence.

Study of morphology and chemical composition of phytoliths on the surface of paddy straw

Paddy and Water Environment, 2014
Silica though nutritionally insignificant plays important role in plants. Most of the silica from absorbed water is precipitated and deposited inside or between plant cells to form ‘phytoliths’ which provide mechanical strength and aid in protection from physical, chemical and biological stresses of the plant.

Morphology, Diversity and Frequency Based Exploration of Phytoliths in Pennisetum typhoides Rich

National Academy Science Letters, 2012
Pennisetum typhoides of the family Poaceae is one of the major cereal crop of India which accumulates silica in the form of phytoliths. Silica which forms phytoliths in the plants protects the plant from various biotic and abiotic stresses. Silica also offers durability stiffness and mechanical support to the leaves and stem.

Morphology and distribution of epidermal phytoliths in Triticum aestivum L.

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2003
ABSTRACT Opaline silica depositions (opal phytoliths) in epidermal cells of leaves of Triticum aestivum cv. Ofanto of different age and position are described. Phytoliths of different shape and size were isolated with a modified wet oxidation method. They have been classified according to the description given by other workers on Graminaceae.

Morphological Analysis of Opal Phytoliths for Soil Discrimination in Forensic Science Investigation

Journal of Forensic Sciences, 1986
Abstract A morphological analysis of opal phytoliths in soils was applied to forensic science soil discrimination. To examine a variation of opal phytolith composition with a difference of land use or topography, a region was chosen in a range of 5 km covering from diluvial plateau to alluvial plain.

Morphological characteristics of phytoliths from representative conifers in China

Palaeoworld, 2016
Abstract Coniferous phytoliths in sediments are an effective tool for detecting the historical appearance of conifers. However, at the timberline in mountainous areas, such coniferous phytoliths are easily confused with grass phytoliths. This study analyses modern phytoliths from 17 conifer plants. Six common types and six rare types were identified.

Morphological trend analysis of rice phytolith during the early Neolithic in the Lower Yangtze

Journal of Archaeological Science, 2014
Abstract The investigation of rice domestication process is important for understanding how agriculture evolved in China. In this paper, we studied samples of rice phytoliths from the Shangshan (around c. 11,000–9000 cal. BP), Kuahuqiao (around c. 8200–7200 cal. BP) and Hemudu (around c. 7000–6500 cal. BP) periods in the lower valley of Yangtze River.

Morphological variation of phytoliths according to leaf senescence and position in the organs of Brachiaria decumbens

Flora, 2019
Abstract Phytoliths are biomineralizations of amorphous silica, formed through root absorption of silicic acid from the soil solution. These particles increase plant protection against biotic and abiotic stresses. The morphology of the phytoliths and their position in Brachiaria decumbens was characterized and described. Samples of root, stem, leaves

Drought influences the phytolith morphology variation and its occluded carbon of leaves in Dendrocalamus Ronganensis during growing season

2021
<p><strong>Abstract: </strong>Being an important carbon (C) sink on Earth, phytolith occluded carbon (PhytOC) has been investigated in various soil-plant systems. Yet, the environmental factor (i.e., drought) is less studied on the variation of phytolith, its relative depositions in plant tissues ...

A Comparison and Differentiation of Phytoliths from Maize and Wild Grasses: Use of Morphological Criteria

American Antiquity, 1984
Phytolith analysis in archaeology suffers from a lack of taxonomic data on silicified forms in plant domesticates and related wild species. This study presents the results of a comparative analysis of phytolith size and morphology in maize (Zea mays L.) and wild grasses. Grass phytolith morphology is highly diverse.
