Фитолиты Злаков Северного Алтая

Abstract: <p>The article presents the results of analysis of the phytolith composition of cereals in the Northern Altai. Some 23 species of <em>Poaceae</em> have been studied. For each species, we analyzed a set of silicon particles in leaves, stems, and generative structures. We selected from 22 to 27 significant morphotypes of phytoliths, depending on their morphological affinity. Our results were compared with the wetting factor. We also analyzed the ratio of the composition of phytoliths of cereals… Show more

“…Another important morphotype that could prove useful is trapezoidal bilobate ("Stipa-type" of Mulholland, 1989;Fredlund and Tieszen, 1994). In North America it was originally defined from what is now considered a separate genus Achnatherum (Barkworth, 1981), but is ironically relatively rare in true Stipa in Eurasia, which produces more saddles or tall rondels (Speranskaya et al, 2018). However, in this study, many trapezoidal bilobates were found in communities dominated by Brachipodium pinnatum (L.) Beauv., an important dominant grass of pine forests of Eurasia.…”

“…In alpine lichen heath it may be from Festuca ovina. In contrast, low pyramidal rondel in the alpine and subalpine communities may be contributed by other Festuca species, and in lowland communities by Elymus-Leymus group of species (Speranskaya et al, 2018).…”

“…В различных публикациях отмечены для следующих родов: Agrostis, Calamagrostis, Bromus, Dactylis, Lolium, Poa и др. (Blinnikov, 2005;McCune, Pellatt, 2013;Speranskaya et al, 2016Speranskaya et al, , 2018. Среди исследованных нами видов указанный морфотип наиболее характерен для Agrostis gigantea (табл., рис.…”

“…Pooideae, которое является основным на территории юга Западной Сибири, характерно наличие следующих специфичных морфотипов: ронделей, трапециевидных полилопастных и двулопастных частиц. Часто присутствует окремнение трихом и длинных клеток (Twiss et al, 1969;Speranskaya et al, 2014Speranskaya et al, , 2018. Специфичность форм фитолитов на родовом и видовом уровнях показана только для культурных злаков и, по большей части, на основе морфометрических параметров (Ball et al, 1996(Ball et al, , 1999.…”
