In this study, the pollen morphology of 11 taxa belonging to Atossa (Alef.) Asch. & Graebner, Hypechusa (Alef.) Asch. & Graebner, Peregrinae Kupicha, Wiggersia (Alef.) Maxted, Vicia L. and Narbonensis (Radzhi) Maxted sections of the genus Vicia L. subgenus Vicia (Fabeae, Fabaceae) naturally growing in Turkey has been studied using Light Microscopy (LM) and Scanning Electron Microscopy (SEM) to evaluate the taxonomic relevance of pollen characters. Twelve morphometric characters are analysed with one-way analysis of variance and Tukey's honestly significant difference test for multiple comparisons. Of the taxa studied V. narbonensis var. narbonensis (sect. Narbonensis) has the largest pollen grains (P = 51.98 mu m x E = 30.52 mu m) and V. lathyroides (sect. Wiggersia) has the smallest pollen grains (P = 27.71 mu m x E = 20.14 mu m). The pollen grains are subprolate to perprolate (P/E = 1.16-2.11), but the prolate shape occurs in the majority of the taxa. The regular pollen grains of all taxa are trizonocolporate, isopolar, and released in monads. Ornamentation of the mesocolpium is psilate-perforate in V. lathyroides (sect. Wiggersia), reticulate-rugulate in V. narbonensis var. narbonensis (sect. Narbonensis), (micro)reticulate in V. sericocarpa var. sericocarpa (sect. Hypechusa), V. sativa subsp. sativa (sect. Vicia) and V. grandiflora var. grandiflora (sect. Vicia), and reticulate-perforate in the remaining taxa. The apocolpium and colpus area are psilate or perforate in all taxa except V. sericocarpa var. sericocarpa (sect. Hypechusa) and V. sativa subsp. sativa (sect. Vicia), which exhibit the obscurely reticulate-perforate pattern. Several palynological features have taxonomic importance in sectional level: polar axis, equatorial diameter, pollen shape (P/E ratio), colpus length, colpus width, size of pori, porus length/width ratio, lumina diameter, muri thickness and ornamentation. The results also indicate that pollen characters can be useful in distinguishing the examined taxa.


Pollen morphology of 10 taxa belonging to Prangos Lindl. and Ekimia H. Duman & M.F. Watson (Umbelliferae) from turkey and its taxonomic significance
Pehlivan, Sevil; Baser, Birol; Cabi, Evren (Bangladesh Journals Online (JOL), 2009-12-5)
Pollen grains of nine taxa of Prangos Lindl. and one of Ekimia H. Duman & M.F. Watson (Umbelliferae) were examined with LM (light microscope) and SEM (scanning electron microscope), and of them four with TEM (transmission electron microscope). The quantitative data were also subjected to cluster analysis. The obtained phenogram revealed that Ekimia bornmuelleri (Hub.-Mor. & Reese) H. Duman & M.F. Watson is strictly different from the taxa of Prangos regarding their quantitative pollen profile; except ...
Pollen morphology of some taxa of Vicia L. subgenus Vicilla (Schur) Rouy (Fabaceae) from Turkey
Binzat, Okan Kaan; KAHRAMAN, AHMET; Doğan, Musa (2014-10-01)
The pollen morphology of the ten taxa belonging to Cassubicae Radzhi, Cracca Dumort., Ervilia (Link) Koch, Lentopsis Kupicha, Trigonellopsis Rech. f. and Variegatae Radzhi sections of the genus Vicia L. subgenus Vicilla (Schur) Rouy (Fabeae, Fabaceae) in Turkey has been examined by use of light microscopy and scanning electron microscopy. Twelve morphometric characters are analysed with one-way analysis of variance and Tukey's honestly significant difference test for multiple comparisons. Polar axis and equ...
DNA fingerprinting and genetic characterization of Anatolian Triticum spp. using AFLP markers
Yildirim, Figen; Akkaya, Mahinur (Springer Science and Business Media LLC, 2006-08-01)
In this study, genetic analysis of Triticum spp. was carried out using AFLP markers. Six AFLP selective combinations were scored as presence and absence of bands for all the individual samples obtained from a single seed of each accession (70 accessions); T. baeoticum (21), T. monococcum (5), T. urartu (16), T. araraticum (7), T. dicoccoides (16) and T. dicoccon (5), resulting in 506 polymorphic AFLP bands. The phylogenetic tree showed two major clusters; one was composed of T. monococcum (AA) and T. baeoti...
New Araucarian Conifer from the Late Cretaceous (Campanian-Maastrichtian) of Southeastern Turkey
Kvacek, Jiri; Yılmaz, İsmail Ömer; Hosgor, Izzet; Mendes, Mario Miguel (University of Chicago Press, 2019-07-01)
A new fossil conifer Araucaria rothwellii J.Kvaek from the Campanian-Maastrichtian marine sediments of the Bozova Formation in southeastern Turkey is described based on leaf compressions and leaf impressions. The new species is characterized by twigs possessing helically arranged broadly lanceolate leaves with attenuate apexes and slightly narrowed bases. Amphistomatic leaves bear stomata arranged in rows surrounded by four to six subsidiary cells; the rows are longitudinal to the leaf margin. Ordinary epid...
Genetic relationships among perennial and annual Cicer species growing in Turkey as revealed by allozymes
Sudupak, MA; Kence, Aykut (Springer Science and Business Media LLC, 2004-05-01)
Allozyme polymorphisms were used to assess genetic variation and relationships among ten Cicer species ( annuals and perennials) growing in Turkey. Using seven enzyme systems, 12 putative scorable loci were detected and surveyed for polymorphism in an accession collection including wild and cultivated forms. Variation was generally low within accessions and species, but common between species. Cluster analysis based on the pairwise genetic distance coefficients (Nei 1978) among accessions and species using ...
