    Contribution to the knowledge of the pollen morphology of the genus Salvia (Lamiaceae)
    (Magnolia Press, 2020) Ozler, Hulya; Kahraman, Ahmet; Pehlivan, Sevil; Dogan, Musa; Baser, Birol; Fisne, Ahter Yavru; Bagherpour, Safi
    The pollen grains of 19 Turkish Salvia species in Aethiopis, Drymosphace, Hemisphace, Hymenosphace and Salvia sections, 13 of which are endemic to Turkey, were investigated, documented and illustrated through Light Microscopy (LM) and Scanning Electron Microscopy (SEM). This study provides pollen data of 14 species for the first time. The pollen grains of the species examined are monads, isopolar, radially symmetrical and hexacolpate, mostly medium in size, slightly elliptic to more or less circular in polar view and mainly oblate-spheroidal in equatorial view. Two different ornamentation types are recognized on exine sculpturing; reticulate-perforate and bireticulate. The present results do not generally support the traditional infrageneric classification of Salvia, but provide useful pollen characters for species delimitation.

    Pollen morphology and systematical contribution of some Onosma (Boraginaceae) taxa distribution in Turkey
    (Springer Wien, 2014) Binzet, Riza; Erkara, Ismuhan Potoglu; Ozler, Hulya; Pehlivan, Sevil
    In this study, the palynological characteristics and its taxonomic implications of 30 different Onosma L. taxa, which belong to sections Protonosma M. Popov., Podonosma (Boiss.) Gurke. and subsections Haplotricha (Boiss.) Gurke., and Asterotricha (Boiss.) Gurke. of section Onosma were investigated under Light Microscope (LM), Scanning Electron Microscope (SEM) and pollen of four taxa with Transmission Electron Microscope (TEM). Pollen grains are mostly heteropolar and trisyncolporate rarely isopolar and tricolporate (O. rostellata and O. orientale), subprolate or prolate to spheroidal and exine tectate-perforate (O. rostellata, O. sericea and O. auriculata) and tectate-imperforate (O. bracteosa). In the conclusion of the study it has been determined that investigated Onosma species have shown three different types of ornamentation, namely scabrate (O. sericea type, O. auriculata type and O. orientale type), rugulate (O. rostellata type) and scabrate-rugulate (O. bracteosa type). It was pointed out that these different types of ornamentation can be used to separate the sections and similar taxa from each other. Pollen grains of O. lycaonica Hub.-Mor., O. bracteosa Hausskn. & Bornm., O. caerulescens Boiss. and O. taurica Willd. var. taurica from subsection Asterotricha have an operculum.

    Pollen morphology of Agropyron Gaertner in Turkey
    (Bangladesh Journal of Plant Taxonomy, 2009) Özler, Hülya; Cabi, Evren; Us, Ebru; Doğan, Musa; Pehlivan, Sevil
    Pollen morphology of Agropyron cristatum (L.) Gaertner. s.s. (subsp. incanum (Náb?lek) 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. The scabra density and the height of scabrae as well as other morphological parameters such as annulus and operculum diameter are peculiar features for differentiation of taxa. Two different phenograms were created with the UPGMA (Unweighted Pair Group Method with Arithmetic mean) clustering technique using quantitative measurements of the pollen grains.

    Pollen morphology of Hymenosphace and Aethiopis sections of the genus Salvia (Lamiaceae) in Turkey
    (Tubitak Scientific & Technological Research Council Turkey, 2013) Ozler, Hulya; Pehlivan, Sevil; Celep, Ferhat; Dogan, Musa; Kahraman, Ahmet; Fisne, Ahter Yavru; Baser, Birol
    Palynological characteristics of 30 Salvia taxa in sections Hymenosphace and Aethiopis from Turkey were investigated by light and scanning electron microscopy. S. aethiopis (sect. Aethiopis) has the smallest pollen while S. blepharochlaena (sect. Hymenosphace) has the largest pollen. The basic shape of the pollen grains in most taxa is suboblate, oblate-spheroidal, or prolate-spheroidal to spheroidal; however, subprolate pollen grains are occasionally are found in S. cassia of sect. Aethiopis. Hexacolpate pollen is dominant in all studied taxa, but heptacolpate and octacolpate pollen grains are mixed together in S. palaestina (heptacolpate, 20%) and S. candidissima subsp. candidissima (heptacolpate, 2% and octacolpate, 40%). The exine sculpturing is bireticulate (the common type) or reticulate-perforate. The bireticulate and the reticulate-perforate sculpturing patterns can be divided into subtypes according to the number of primary lumina. Taxonomic implications of the pollen data are also discussed.

    Pollen morphology of some Allium L. (Lilliaceae) taxa in Turkey
    (Bangladesh Journal of Botany, 2010) Özler, Hülya; Pehlivan, Sevil
    Pollen grains of 16 taxa of Allium L. belonging to sections Rhizirideum G. Don ex Koch., Codonoprasum Reichb. and Allium L. were investigated using light and scanning electron microscope, and pollens of four taxa were also examined with transmission electron microscope. Pollens were monosulcate and ellipsoidal. It was observed that the sulcus extends from distal to proximal in all taxa. The exine was semitectate and the tectum was perforate. Columellae were simplicolumellate. Exine sculpture was striate-perforate, striate-rugulate-perforate and rugulate-perforate. A. albidum Fischer ex Bieb. subsp. caucasicum (Regel) Stearn, A. rupicola Boiss ex Mouterde and A. asperiflorum Miscz. were seen to have an operculum.

    Pollen Morphology of Some Centaurea L., Psephellus Cass. and Cyanus Miller Taxa
    (ACTA BIOLOGICA CRACOVIENSIA Series Botanica, 2009) Özler, Hülya; Kaya, Zafer; Pehlivan, Sevil
    The pollen morphology of 29 taxa, 24 of which are endemic to Turkey, was investigated in detail by light and scanning electron microscopy. LM examination showed pollen grains to be tricolporate, rarely tetracolporate, isopolar, radially symmetrical, subprolate, spheroidal-subprolate, operculate, tectum perforate, scabrate and microechinate. P. pecho Albow. and P. appendicigera C. Koch resemble the Montana type, C. pichleri subsp. pichleri Boiss. and C. pichleri subsp. extrarosularis (Hayek & Siehe) Wagenitz resemble the Cyanus type, and C. pseudoscabiosa subsp. pseudoscabiosa Boiss.& Buhse are consistent with the Dealbata type, C. pestalozzae Boiss. and C. carduiformis subsp. carduiformis DC. with the Scabiosa type, and the other taxa with Wagenitz's Jacea type.

    Pollen morphology of the genus Salvia L. (Lamiaceae) in Turkey
    (Elsevier Gmbh, Urban & Fischer Verlag, 2011) Ozler, Hulya; Pehlivan, Sevil; Kahraman, Ahmet; Dogan, Musa; Celep, Ferhat; Baser, Birol; Yavru, Ahter
    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 is suboblate, oblate-spheroidal or prolate-spheroidal. However subprolate pollen grains are recorded for S. macrochlamys from sect. Salvia. The grains are hexacolpate in all taxa, but in S. recognita from sect. Salvia also octacolpate pollen was found. Three distinct exine sculpturing types exist, reticulate-perforate (the common type), reticulate-granulate and bireticulate. The reticulate-perforate and bireticulate sculpturing patterns can be divided into subtypes based on the number of perforations and the number of secondary lumina in each primary lumen. Pollen morphological characteristics of the taxa studied are compared and discussed on the basis of taxonomical concepts. In some cases, these characters are useful in distinguishing the sections. For instance, the presence of 1-2 large central secondary lumina per primary lumen is a significant character of sect. Horminum separating it from the other sections. As well, the presence of holes on colpus membrane ornamentation can be used as a diagnostic taxonomic character for sectional division between sect. Hemisphace and others. S. ballsiana from sect. Salvia is clearly distinct from the other taxa examined by its unique pollen morphology. Further, for several macromorphologically similar taxa pollen structures provide additional evidence to delimite them from each other. (C) 2010 Elsevier GmbH. All rights reserved.
