Assessing Bioturbation in Archaeological Sediments using Soil Morphology and Phytolith Analysis
Journal of Archaeological Science, 1999Abstract Analysis of ditch infill at an early modern burial complex (dating from the 16th century ad) in upland northwestern Thailand was undertaken to assess the role of bioturbation in interpreting palaeolandscapes. Evidence for bioturbation and water percolation is contrasted with AMS radiocarbon determinations and a phytolith sequence. While more

Phytolith morphology research on wild and domesticated rice species in East Asia
Quaternary International, 2013Abstract Systematical descriptions of phytoliths from rice species in East Asia are scarce. In order to investigate the relationship among diversity of phytolith morphology, taxonomy and genome, comparative research on phytolith morphology of the wild and domesticated rice species is first performed on the basis of statistics and cluster analysis ...

Silicon is an essential element for the growth and development of bamboo plants that significantly affects the biochemical and physical properties for industrialized bamboo utilization. Silicon is biomineralized as diverse forms of phytoliths in the bamboo organs.

Morphological Classification of Grass Phytoliths
Soil Science Society of America Journal, 1969Abstract Opal phytoliths derived from epidermal cells of grass leaves have been identified in atmospheric dust, soils, paleosols, Pleistocene loess, and deep‐sea sediments. By comparing oriented shapes of phytoliths in spodograms of 17 common grass species, four classes and 26 types are proposed which distinguish three groups of ...

Morphological characterisation of silica phytoliths in Neotropical Marantaceae leaves
Plant Systematics and Evolution, 2013The Marantaceae family is composed of 550 species of pantropical distribution, with a strong clustering in the Neotropics. Although the family forms a monophyletic group, the circumscription of genera and consequently its phylogenetic relationships are not sufficiently understood.

The analysis of wild rice cell structures, tissues, organs, and other morphological characteristics and the development of identification markers for wild rice are the basis for identifying the origins and evolution of prehistorical rice agriculture. However, contemporary wild rice strains are often subject to gene introgression from domesticated rice ...

The effects of chemical composition and distribution on the preservation of phytolith morphology
Applied Physics A, 2013Different 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, 2014Silica 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.
