    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.

    EFFECTS OF METEOROLOGICAL FACTORS ON POLLEN FLORA IN THE ATMOSPHERE OF SINOP (TURKEY)
    (Bangladesh Botanical Soc, 2021) Demir, Cemile Cansi; Ozler, Hulya; Kaplan, Ayse
    This study was conducted for determining the plant taxa of the pollen grain in the atmosphere of the city center of Sinop (Turkey) and investigating the effects of meteorological factors on pollen concentration, by analyzing daily, weekly and monthly changes in the atmosphere. The types and amounts of pollen grain in the atmosphere were determined using Burkard trap. On the basis of the average of 2 years (2016 - 2017), the dominant trees taxa in the atmosphere were Cupressaceae/Taxaceae (32.67%), Pinaceae (15.51%), Morus sp. (5.50%), Quercus sp. (2.76%), Alnus sp. (2.24%), Corylus sp. (1.48%), Carpinus sp. (1.43%), Juglans sp. (1.43%), Fraxinus sp. (1.33%), Olea europaea (1.05%) and Poaceae (Grass) (5.29%), whereas the dominant weed taxa were Urticaceae ( 11.16%), Ambrosia sp. (4.31%), Amaranthaceae (3.21%), and Mercurialis sp. (2.05%). Temperature and wind speed had a positive effect on the increased amount of pollen, whereas precipitation had a negative effect on it. On the basis of the data obtained, a pollen calendar was prepared for the area.

    First Aeropalynological Survey on the Atmosphere of Sinop, Turkey
    (Kastamonu Univ, 2020) Ceter, Talip; Ozler, Hulya; Pinar, Nur Munevver
    Aim of study: With this first aeropalynological study in the atmosphere of Sinop, it was aimed to detect seasonal variation of pollen and its relationship with meteorological parameters. Area of study: This survey was conducted in the atmosphere of the Korucuk district of Sinop. Material and methods: This study was carried out using Hirst-Burkard 7-day volumetric trap between July 2010 and June 2012. Main results: During a period of two years, pollen of 61 taxa that included 37 taxa of trees, 23 taxa of other weeds and Poaceae were recorded with the sum of 93,414 pollen grain. Pollen of trees (69.5%) predominantly contributed to the pollen sum followed by Poaceae (17.1%) and other weeds (13.4%). Highlights: Alnus (2.6%), Amaranthaceae (3.4%), Betula (1.3%), Carpinus (2.6%), Compositae (6.2%), Corylus (23.1%), Cupressaceae (13.7%), Fraxinus (1.7%), Pinaceae (16.1%), Plantago (1.1%), Poaceae (17%) and Quercus (2.2%) were determined as the dominant taxa in the atmosphere. Among the meteorological parameters, temperature and wind speed generally had a positive effect on pollen concentration, while rainfall had a negative effect on it. A pollen calendar was prepared as a result of the pollen grain detected in the atmosphere of Sinop.

    PALYNOCHEMICAL QUALITY MONITORING OF HONEY SAMPLES IN AND AROUND ESK??EH?R PROVINCE, TURKEY
    (Bangladesh Botanical Soc, 2023) Erkara, Ismuhan Potoglu; Ozler, Hulya; Pehlivan, Sevil; Sezer, Okan
    Honey is used in traditional medicine for a long time. Nectar which is the most important component of honey was produced by plants. In the present study, pollen and biochemical analysis of honey samples collected from different regions of Eskisehir were studied. Seventy taxa of pollens under 29 family and 41 genera in 41 honey samples were identified. Pollens were classified as dominant, secondary, minor and rare for frequency distribution. According to Wodehouse method, pollen spectra was determined. Palynochemical properties of honey samples in and around Eskisehir were deduced.

    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 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 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.
