Öğe Centaurea sakariyaensis (Asteraceae), a new species from Turkey(TAYLOR & FRANCIS LTD, 2017) Uysal, Tuna; Dural, Huseyin; Tugay, OsmanIn this paper, a new Centaurea L. (Asteraceae) species from Turkey is described and illustrated. Centaurea sakariyaensis Uysal & Dural grows on rocky crevices in Sakarya province in north-western Anatolia. It belongs to C. sect. Centaurea L. and taxonomically its closest relative is C. wiedemanniana. Diagnostic morphological characters from a very similar taxon are provided, and a key from flora of Turkey is modified that includes related species of sect. Centaurea. The geographical distribution of the new species and species of other related taxa of the same section are mapped. The chromosome number of C. sakariyaensis, 2n=18, counted in root tips, is also reported and illustrated.Öğe Chemical Composition of The Essential Oil of The Flowers and Leaves of Calba Tea (Dorystoechas hastata Boiss & Helder. ex Bentham)(TAYLOR & FRANCIS LTD, 2016) Özcan, Mehmet Musa; Chalchat, Jean Claude; Figueredo, Gilles; Bağcı, Yavuz; Dural, Huseyin; Savran, Ahmet; Al-Juhaimi, Fahad Y.The essential oils of flower and leaves of Dorystoechas hastata Boiss & Helder. ex Bentham, grown in Turkey, was obtained by hydrodistillation and analysed by GC and GS-MS. Fourty components were identified in the flowers oil, which represented about 93.97 % of the total composition of the oil. The major constituents of the flower essential oil were myrcene (19.37 %), 1,8-cineole (14.30 %), beta-pinene (9.19 %), alpha-pinene (8.49 %) and beta-caryophyllene (6.18 %). Thirty-seven components were established in the leaves oil, making up 97.16 % of the total composition. The main constituents of the essential oil of the leaves were myrcene (20.71 %), 1,8-cineole (18.76 %), beta-pinene (12.51 %), alpha-pinene (8.54 %), bornyl acetate (7.28 %) and terpinene-4-ol (6.19 %). As seen, myrcere, 1,8-cineole and beta-pinene for both oils were the main components.Öğe Karyological Studies of the Genus Onobrychis Mill. And the Related Genera Hedysarum L. And Sartoria Boiss. & Heldr. (Fabaceae, Hedysareae) From Turkey(Firenze Univ Press, 2012) Arslan, Emine; Ertuğrul, Kuddusi; Tugay, Osman; Dural, HuseyinNine chromosome counts in several genera of the tribe Hedysareae from Turkey, six species of Onobrychis, two species of Hedysarum and one species of Sartoria, were reported and all karyotypes were prepared. Six of them are new. One of the other three reports is a confirmation of polyploidy, another report is a confirmation of chromosome count and the last report is a confirmation of both chromosome count and karyotype morphology. Except for karyotype of O. altissima, all karyotypes were presented in this study first.Öğe Karyomorphological study of five Turkish endemic Rhaponticoides Vaill. (Asteraceae, Cardueae) species(TAYLOR & FRANCIS LTD, 2016) Uysal, Tuna; Sezer, Ela Nur Simsek; Bozkurt, Meryem; Tugay, Osman; Ertugrul, Kuddisi; Demirelma, Hakki; Dural, HuseyinIn this paper, we aimed to determine the chromosomal features of Turkish endemic Rhaponticoides species. The chromosome numbers and karyomorphology of five species were examined. The chromosomal counts confirmed the previous reports of 2n = 30 given for Rhaponticoides species growing in different countries. Although R. iconiensis had a karyotype formula of 28m + 2sm, the remaining four species all had 26m + 4sm. Rhaponticoides aytachii and R. hierroi were especially similar in asymmetry indices. Rhaponticoides iconiensis and R. phytiae had satellites in the fourth and second chromosome pairs, respectively. Having the most symmetrical chromosomes, R. amasiensis displayed an important relationship with R. iconiensis and R. phytiae in terms of total chromosome length (TCL). If we make an overall assessment in terms of chromosomal asymmetry, chromosomes indices continues in the low range for each species and this low asymmetry indeces indicate that the species have symmetric chromosomes as karyomorphology. In conclusion, this is the first report which describes the karyotypes and chromosomal asymmetry indices of Turkish endemic Rhaponticoides species.Öğe Morphological, anatomical, palynological, and micromorphological characters of 2 endemic species of Ornithogalum (O. chetikianum and O. demirizianum) in Turkey(TUBITAK SCIENTIFIC & TECHNICAL RESEARCH COUNCIL TURKEY, 2015) Citak, Burcu Yilmaz; Dural, Huseyin; Buyukkartal, Hatice Nurhan; Pinar, Nur MunevverIn this investigation, the comparative morphological, anatomical, palynological, and micromorphological characters of Ornithogalum chetikianum Uysal, Ertugrul & Dural and O. demirizianum Malyer & Koyuncu, which belong to Ornithogalum subgenus Myogalum (=Honorius) (Asparagaceae), are presented. In accordance with the new observations, dimensions of some morphological characters are revised as distinct from the previous description of the species. Anatomical investigations of roots, scapes, and leaves were found to be useful for taxonomy. Some anatomical characters, such as the number of protoxylem arms in the root, the number of cortex and sclerenchyma layers in the scape, and type of mesophyll cells in the leaf, provide information of taxonomical significance. Pollen grains of O. chetikianum are monosulcate, but the pollen grains of O. demirizianum are both monosulcate and zonosulcate (10%). As a result of this study, some pollen characteristics such as aperture type, pollen shape, and exine ornamentation were demonstrated to be different between the species. Capsules and seeds of the species are different from one another, especially in their shapes. The investigated species are compared with the other studied species in the subgenus Myogalum.Öğe Morphology and anatomy of Hedysarum pannosum (Boiss.) Boiss. (Fabaceae)(UNIV ZAGREB, FAC SCIENCE, DIV BIOLOGY, 2015) Dural, Huseyin; Citak, Burcu YilmazThe aim of this paper is to investigate morphological, anatomical, palynological, fruit and seed micromorphological properties of Hedysarum pannosum (Boiss.) Boiss. A detailed description of the species is reported for the first time in this study. The morphological features of the species have been compared with the results of previous investigations. Anatomical studies have been carried out on cross-sections of roots, stems, leaflets and petioles. The anatomical results show that the plants have secondary growth roots, protruding stems, amphistomatic and equifacial leaves with tannin, triangular shaped petioles. Hedysarum pannosum pollen are tricolpate, prolate and pollen exine ornamentation is reticulate. Fruits have trichomes on their setae and tomentose trichomes have papillae. Seeds are reniform and they have rugolo-reticulate ornamentation.Öğe Muscari turcicum (Liliaceae/Hyacinthaceae), a new species from south Anatolia, Turkey(BLACKWELL PUBLISHING, 2007) Uysal, Tuna; Ertugrul, Kuddisi; Dural, Huseyin; Kucukoduk, MustafaMuscari turcicum Uysal, Ertugrul & Dural (Liliaceae/Hyacinthaceae) is described and illustrated from south Anatolia, Turkey. This species grows on alpine steppe in the Middle Taurus (C4 Konya Province). Muscari turcicum, an endemic confined to the Middle Taurus, is closely related to M. discolor Boiss. & Hausskn. and M. anatolicum Cowley & Ozhatay. Diagnostic morphological characters are discussed and compared with those of closely related taxa. (C) 2007 The Linnean Society of London.Öğe A new species of Cousinia (sect. Cousinia, Asteraceae) from the Agri Mountain (eastern Turkey): evidence from morphology, karyology and anatomy(MAGNOLIA PRESS, 2019) Tugay, Osman; Ulukus, Deniz; Ertugrul, Kuddisi; Uysal, Tuna; Demirelma, Hakki; Dural, HuseyinCousinia agridaghensis (sect. Cousinia) from Agri province, eastern Turkey, is described as new to science. The new species is morphologically closely related to C. urumiensis, C. fedorovii and C. armena but differs in capitula shape, synflorescence shape, stem height, shape of segments of basal and uppermost cauline leaves. In addition, the new species is compared with C. urumiensis, which is distributed in Turkey, in terms of chromosome number and anatomical features. The basic chromosome number is determined x = 12 in C. agridaghensis and x = 13 in C. urumiensis. The differences in leaf midrib shape and number of vascular bundles in C. agridaghensis and C. urumiensis are observed. The achene coat and pollen grain surface of C. agridaghensis and C. urumiensis are studied with SEM photographs. Furthermore, a detailed description, distribution map, conservation status and ecology of the new species are given.Öğe A survey of the morphology, anatomy, and palynology of endemic bornmuellera kiyakii and b. glabrescens (brassicaceae) from Turkey(GAZI UNIV, 2019) Gonen, Burcu; Dural, Huseyin; Yilmaz Citak, BurcuIn the present study, the morphological, anatomical, and palynological properties of 2 Bornmuellera Hausskn. taxa, which are endemic to Turkey, were examined. B. kiyakii Aytac & Aksoy is known from the province of Konya, growing in serpentine areas, and B. glabrescens (Boiss. & Balansa) Cullen & T. R. Dudley is known from the province of Nigde. Through morphological analyses, the characteristics of the taxa were designated and the descriptions were expanded. The morphology of the stem, leaf, trichomes, and capsule are essential to separate the examined taxa. The anatomical analyses showed that the taxa had similar anatomical root, stem, and leaf tissue layers; however, their rows, and mesophyll thickness were different between the taxa. Anatomical traits, such as the presence of an endodermis in B. kiyakii, the pith region in the cross-sections of the stems, linear-shaped leaf in B. glabrescens, and triangular-shaped leaf in B. kiyakii have taxonomic importance. The pollen grains of the studied taxa were tricolpate, isopolar, and radial symmetrical, prolate-spheroidal, and had reticulate ornamentation. The fruit of B. kiyakii were characterized by globose, asymmetrical, and yellow-purplish-pink valves with rugose ornamentation, which clearly differed from that of B. glabrescens, which had ovoid, symmetrical, and light green-yellow valves. The seed traits clearly appeared to have taxonomic significance. The seeds of B. glabrescens were orbicular-shaped, yellowish-brown in colour, with reticulate ornamentation; however, the seeds of B. kiyakii were oblong-elliptic-shaped, and the tile was red-brown in colour.
