“…Their morphological classification was accomplished based on Twiss et al [3], whilst the denomination of individual morphotypes was accomplished according to the International Code for Phytolith Nomenclature 1.0 (ICPN 1.0 [30]). The classification and nomenclature work was complemented with the system of other authors (e.g., [16,28,[31][32][33][34]). Meanwhile we documented the phytolith morphotypes by taking microphotographs.…”

Quantifiable differences between phytolith assemblages detected at species level: analysis of the leaves of nine Poa species (Poaceae)

The taxonomic value of phytolith assemblages and their degree of variability within different species of the same genus is still an undervalued issue in the botanical range of phytolith studies. However the understanding of grass phytolith variance and its implications to plant systematics is doubtless.In the present study phytoliths of the lateral shoots (leaves) of nine, globally distributed Poa species (Pooideae -Poaceae) are described. Phytoliths were recovered from Poa specimens by the dry ashing technique. Altogether 6223 disarticulated phytoliths were counted (approximately 500-700 phytoliths per species) in 54 plant samples, which cover six shoots of nine species. Not only the relative frequency of each morphotype was calculated, but measurements were conducted to determine the biogenic silica content of Poa lateral shoots. A phytolith reference collection for the nine selected species of a worldwide importance was also compiled. The description of the most significant phytolith morphotypes and their taxonomic relationships are given here.Results suggest that the biogenic silica content of the Poa lateral shoots was determined to be relatively high within all nine species. Phytolith assemblage data was subjected to multivariate statistical analyses (e.g., CA and PCA) in order to find differences and similarities among the nine Poa species. Results show that the two closely related Poa of the P. pratensis species group, namely the P. pratensis and P. angustifolia, only slightly differ from the other Poa species if we consider their rondel-trapeziform short cells (SC) phytolith frequencies.

“…The genus includes important turf and forage grasses (Arrhenatheretea) [15,16] and cultivars as well as troublesome weeds and invaders [14,17]. Although primarily found in the temperate zone, Poa is a very widely distributed grass genus [18].…”

“…Эта же форма была отмечена и у некоторых других представителей подсемейства Pooideae, но в небольшом количестве. Странно почти полное отсутствие фитолитов этой формы у ковылей, тогда как в других исследованиях она указана для этого рода [Сперанская и др., 2014] [Кисилева, 1989;Blinnikov, 2005]. В целом наблюдается как у некоторых ксерофитов, так и некоторых формами в отличии от видов сухих местообитаний.…”

2008. Silicon, oxygen and carbon isotope composition of wheat (Triticum aestivum L.) phytoliths: implications for palaeoecology and archaeology.ABSTRACT: Six mature wheat (Triticum aestivum L.) plants from one crop were collected one week before harvest, and organs were separated as follows: culm, rachis, leaf sheaths, leaf blades and inflorescence bracts. Percentage silica (% SiO 2 ), % C, % N and d 13 C were determined in these samples. Phytoliths isolated from the individual organs were subsequently analysed for d 29 Si, d 30 Si, and d 18 O, as well as % C, % N and d 13 C from occluded organic material within the phytoliths. Percentage silica was highest in the leaf sheaths and leaf blades and lower in the inflorescence bracts, culm and rachis. d 30 Si and d 29 Si were highly correlated, and both increased in the upper parts of the plant. It appears there are two routes for Si transport within the plant, and that heavier isotopes increase towards the end of both routes. The d 18 O results indicate that the culm and the leaf blades were the sites of highest d 18 O, with lower values in the rachis, leaf sheath and inflorescence. There was no correlation between the accumulation of either heavy silicon isotope ( 29 Si and 30 Si) and heavy oxygen accumulation ( 18 O). d 13 C values were typical of C3 species, and whole plant and isolated phytolith values were similar. Low % N concentrations were detected in phytoliths. # Natural Environment Research Council (NERC)
