Differentiation of globular phytoliths in Arecaceae and other monocotyledons: morphological description for paleobotanical application

TURKISH JOURNAL OF BOTANY, 2015
Globular phytoliths have been mainly assigned to palms, woody trees, and other monocotyledon families from tropical regions. The lack of detailed descriptions of this phytolith morphology and its correct assignments to particular groups could lead to erroneous interpretations of phytolith records.

Grains of truth or transparent blindfolds?:A review of current debates in archaeological phytolith analysis [PDF]

, 2013
Phytolith analysis has become an increasingly popular archaeobotanical tool in the past few decades. Phytoliths have been used to support key hypotheses relating to the domestication of several food crops and in the study of ancient diet, and they are of

Impact of rice cultivar and organ on elemental composition of phytoliths and the release of bio-available silicon

Frontiers in Plant Science, 2014
The continental bio-cycling of silicon (Si) plays a key role in global Si cycle and as such partly controls global carbon (C) budget through nutrition of marine and terrestrial biota, accumulation of phytolith-occluded organic carbon (PhytOC) and ...
