The Flora of Çelikhan District (Adıyaman) and Near Surroundings

Abstract

This study was carried out to determine the flora of Çelikhan District (Adıyaman) and it’s near surroundings. 592 plant samples were collected from the research area. As a result of the evaluation of these plants, totally of 454 taxa were identified, including 295 genera belonging to 62 families. Of these taxa, 3 belong to Pteridophyta and 451 Spermatophyta divisions. Coniferophyta and Magnoliophyta subdivisions in the Spermatophyta division contain 2 and 449 taxa, respectively. It was determined that 449 taxa belonging to Magnoliophyta subdivision, belong to 385 Magnoliopsida and 64 Liliopsida class. It was determined that 30 taxa from the study area were endemic and the endemism rate was found to be 6.6 %. The distribution of taxa according to phytogeographic regions is as follows: Anatolian-Turan 158 (34.8%), Mediterranean 34 (7.5%), Euro-Siberian 33 (7.1%), multi-regional and unknown phytogeographical regions 229 (50.4%). The first five family according to the number of taxa; Asteraceae 42 (9.2%), Fabaceae 37 (8.1%), Brassicaceae 36 (7.9%), Lamiaceae 35 (7.7%), Poaceae 31 (6.8%). The first five genera according to the number of taxa; Astragalus 9, Silene 8, Salvia 7, Trifolium 6, Vicia 6. Within the scope of the study, a new and endemic onion species was discovered, named Adıyaman and this species was introduced to the literature as Allium adiyamanense Kılıç & Yıld.

Physical and electrical properties of Sm2O3 doped Boro-Zinc-Vanadate glasses

“…It also explains the degree of structural compactness. Density of the present glass nanocomposites was measured by following Archimedes method and using the following relation [5],…”

“…Boric oxide (B2O3), a glass former has been incorporated into various glasses as a flux material to attain low melting temperatures, thermal stability, etc. [5]. Addition of ZnO enhances glass forming, chemical resistance and reduces crystallization rate.…”

Davda Dağı Florası (Karaman / Türkiye)

“…Due to its cosmopolitan structure and easy spreading with pappus, as well as its adaptation to different habitats, Asteraceae is the most crowded family in the region. The steppe characteristics of the research area and the neighbouring ares seems to fawor Brassicaceae and Poaceae in terms of taxa number (Ekim, 2014;Kılıç, 2022). Astragalus L., Verbascum L., Allium L., Centaurea L., and Silene L. are the most crowded genera in Flora of Turkey.…”
