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 equatorial diameter of pollen grains range from 24.64 to 44.19 and from 15.90 to 30.42 mu m, respectively. The pollen grains are prolate-spheroidal to perprolate (P/E = 1.09-2.07), 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. tenuifolia subsp. dalmatica and V. tenuifolia subsp. tenuifolia (sect. Cracca), reticulate-rugulate in V. villosa subsp. villosa (sect. Cracca), and reticulate-perforate in the remaining taxa. The apocolpium and colpus area are reticulate-perforate in V. hirsuta (sect. Cracca), V. ervilia (sect. Ervilia) and V. lunata subsp. grandiflora (sect. Trigonellopsis), and psilate, psilate-slightly perforate or perforate in the other taxa. The results obtained from analyses of pollen grains from the studied taxa of the subgenus Vicilla reveal significant differences in general morphology and some morphometric attributes, and ornamentation types. However, it is concluded that pollen morphology has proved to be uninformative for differentiating the subgenera Vicilla and Vicia.

POLLEN MORPHOLOGY OF AGROPYRON GAERTNER IN TURKEY Ozler, Hulya; Cabi, Evren; Us, Ebru; Doğan, Musa; Pehlivan, Sevil (2009-06-01) Pollen morphology of Agropyron cristatum (L.) Gaertner. s.s. (subsp. incanum (Nabelek) Melderis and subsp. pectinatum (M. Bieb.) Tzvelev, latter including var. pectinatum and var. imbricatum (Roemer & Schultes) G. Beck) in Turkey has been studied by using light microscope and scanning electron microscope. The above-mentioned taxa are homogenous in both aperture type and exine ornamentation. Pollen grains are monoporate (rarely diporate in the case of var. imbricatum) having scabrate grouped exine surface. T...
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 Vicia (Fabaceae) from Turkey KAHRAMAN, AHMET; Binzat, Okan Kaan; Doğan, Musa (Springer Science and Business Media LLC, 2013-11-01) 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 ana...
Pollen morphology of the genus Salvia L. (Lamiaceae) in Turkey ÖZLER, HÜLYA; PEHLİVAN, SEVİL; Kahraman, Ahmet; Doğan, Musa; Celep, Ferhat; Baser, Birol; Yavru, Ahter; Bagherpour, Safi (2011-01-01) Pollen grains of 30 taxa of the genus Salvia, belonging to sections Salvia, Horminum, Drymosphace, Plethiosphace and Hemisphace from Turkey were examined by light (LM) and scanning electron microscopy (SEM). Detailed pollen morphological characteristics are provided for these taxa. Among the studied taxa, S. verticillata subsp. verticillata from sect. Hemisphace has the smallest pollen grains, and S. pachystachys from sect. Salvia possesses the largest ones. The basic shape of the pollen grains in most taxa...
Pollen morphology of the genus Lamium L. (Lamiaceae) and its systematic implications Atalay, Zeynep; CELEP, FERHAT; BİLGİLİ, BİLGEHAN; Doğan, Musa (2016-01-01) This is the first comprehensive palynological investigation of the genus Lamium. The pollen morphology of 48 taxa (including species, subspecies and varieties) of the genus Lamium was investigated and documented using light microscopy (LM) and scanning electron microscopy (SEM). Lamium pollen is small to medium sized (I) = 21.65-39.96 mu m), oblate-spheroidal to subprolate in shape and tricolpate. Three major exine sculpturing patterns (reticulate, granulate and microreticulate) were observed. The results i...
