Studies on phytolith morphotype variants of some members of Gigantochloa of the subfamily Bambusoideae essay
Abstract. Two new species of Gigantochloa Poaceae: Bambusoideae, from Yunnan, China, namely Gigantochloa brachystachya and G. maneensis, are described and illustrated. G. brachystachya is morphologically similar to G. levis, but differs in its infranodal region with a ring of white hairs, culm leaf with erect leaf, linear and linear. The diversity of the grass subfamily Bambusoideae native to Mexico is represented by two tribes, the tropical woody bamboos Bambuseae with three subtribes, Artrostylidiinae, Chusqueinae and Guaduinae, and the herbaceous bamboos Olyreae with the single subtribe Olyrinae. Furthermore, Bambusa oldhamii, B. vulgaris, reveals that S addle is the dominant morphotype produced by the members of this grass subfamily, regardless of rainfall variations. Phytolith assemblage in the surface soil revealed that S addlemorphs are inversely proportional to rainfall, that is, they increase with decrease in rainfall and vice versa. The diversity of the grass subfamily Bambusoideae native to Mexico is represented by two tribes, the tropical woody. bamboo Bambuseae with three subtribes, Artrostylidiinae, Chusqueinae and. The study shows that S addle is the dominant morphotype produced by the members of this grass subfamily regardless of rainfall variations. The assemblage of phytoliths in the surface of the soil revealed that S addle morphs are inversely proportional to rainfall, i.e. they increase with decrease in rainfall and vice versa. Variation and evolution of the phytolith morphotype with age - Our study showed that the phytolith morphotypes in D. brandisii gradually diversified and evolved with age. late adulthood. More phytoliths were observed per slide in mature than in young organs, indicating that the phytoliths were produced continuously with maturing organs.1. Introduction. Brazil has the largest bamboo biodiversity in the New World Judziewicz et al. 1999. The Atlantic Forest, the Cerrado and the Amazon, of the genera, of all known bamboo species, species, Filgueiras et al. 2016. The true bamboo group, subfamily Bambusoideae of the Bamboo species, is a diverse group of evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. It is also called green gold. Bamboo occupies an unparalleled position. In this study, the assemblage and size variations of phytolith morphotypes in a bamboo Dendrocalamus ronganensis forest plant-soil system were analyzed to study how well soil phytoliths represent the overlying plant community and the taphonomic processes acting on phytoliths. Phytolith contents and morphotype assemblages, definition. Phytolith analysis on thin sections of soil is a technique that inventories the distribution patterns of the phytoliths in soils and sediments, as well as the phytoliths that make up each of these distribution patterns. This allows a better understanding of the origin and depositional history of the phytoliths. Although the study revealed some variations in the concentrations of spherulites, all gypsum fragments analyzed contained very high concentrations. phytolith and PhytOC content of oil palms. Therefore, oil palm should be cultivated for better long-term storage as a phytolith. Study of phytolith taphonomy is necessary to improve the accuracy of paleoenvironmental reconstructions Rovner, 1986 Bowdery, 1999. In this study, a year-long experiment already produced a marginally significant difference in total opal concentrations on grass versus turf.,
