Öğe Amaranthaceae, Chenopodiaceae, Plantaginaceae, Urticaceae ve Asteraceae (Compositae) familyalarına ait bazı alerjen taksonların polen morfolojileri ve toplam protein miktarlarının karşılaştırılması(Gazi Üniversitesi Orman Fakültesi Dergisi, 2005) Pehlivan, Sevil; Özler, Hülya; Bayrak, FilizAnkara ilinden toplanan Amaranthus retroflexus L. (Amaranthaceae) Chenopodium album L. (Chenopodiaceae), Plantago lanceolata L, P. major subsp. intermedia (Gilib.) Lange (Plantaginaceae), Artemisia scoparia Waldst.& Kit. (Asteraceae) ve Kastamonu’dan toplanan Urtica dioica L. (Urticaceae) taksonlarının polen morfolojik yapıları ışık mikroskobunda (IM) incelenmiştir. A. retroflexus, C. album, P. lanceolata ve P. major subsp. intermedia polenleri periporat, sferoidal, U. dioica polenleri triporat ve suboblat’dir. A. scoparia polenleri trikolporat ve sferoidal ‘dir. Ornamentasyon (süsleme) P. major subsp. intermedia’da verrukat, A. scoparia’da skabrat, diğer türlerde ise granulat’dir. Bu taksonların toplam protein miktarları Lowry metoduna göre ülkemizde ilk defa belirlenmiştir. A. scoparia’nın toplam protein miktarı ile yurt dışından getirtilen A. vulgaris ekstraktı karşılaştırılmıştır. Toplam protein miktarının P. major subsp. intermedia (46%), A. vulgaris (38.1%), A. scoparia (30.3%) and A. retroflexus (15.3%)’da C. album (12.5%), P. lanceolata (12.25%) ve U. dioica (12.1%)’ya göre daha fazla olduğu belirlenmiştir.Öğe Analysis of Free Amino Acid and Total Protein Content in Pollen of Some Allergenic Taxa(Asian Journal of Plant Sciences, 2009) Özler, Hülya; Pehlivan, S.; Bayrak, F.This study reports the free amino acid content of pollen grains obtained from old and fresh samples belonging to Pinus nigra subsp. nigra var. caramanica (Loudon) Rehder (black pine) (Pinaceae), Juglans regia L. (walnut) (Juglandaceae), Fraxinus angustifolia Vahl. (ash) (Oleaceae) and Betula pendula L. (birch) (Betulaceae) obtained with the technique of Liquid Chromatography-Mass Spectrometry (LC/MS). Pollen samples were obtained from flowers of the above mentioned taxa in different years. Twenty one amino acids were identified. No histidine was found in F. angustifolia collected 8 years ago. Total protein content of P. nigra subsp. nigra var. caramanica pollens (25.75%) was higher than the remaining taxa; F. angustifolia (13.67%), B. pendula (7.73%) and J. regia (7.55%).Öğe POLLEN ANALYSIS OF THE HONEY FROM SOUTH ANATOLIA(2018) Özler, HülyaFor pollen analysis, 19 honey samples were collected from different localities in Ereğli, Karapınar,Ayrancı and Ulukışla regions of Konya, Karaman and Ulukışla, respectively, in November 2015. Allinvestigated honey samples were multifloral because they contained secondary and minor pollengroups. The dominant group of pollen grains were determined as the families of Fabaceae in 2samples and Scrophulariaceae in 5 other samples, Helianthus annuus in 1 sample and Zea mays in 1sample. Secondary pollen groups consisted of the families of Amaranthaceae, Brassicaceae,Fabaceae, Poaceae, Rosaceae, Scrophulariaceae and genera of Centaurea, Cistus, Eucalyptus andLinaria. Pollen of 55 plant taxa were identified in examined honey samples of which 21 wereclassified on the family level, 30 were on the genera level, 1 was on the tribe level and 3 were on thespecies level. The total number of pollen (TPN-10) in 10 grams of honey ranged from 332 to 42496.According to the results of the TPN-10 analysis in honey samples, 3 samples were normal and otherswere poor. The taxa of Zea mays, Cistus, Poaceae, Scrophulariaceae and Amaranthaceae were foundin pollen sources. Helianthus annuus and Brassicaceae were found in nectar sources. Fabaceae,Rosaceae, Eucalyptus, Centaurea were found in nectar and pollen sources and were identified in thehoneys.Öğe Pollen morphology of Agropyron Gaertner in Turkey(Bangladesh Journal of Plant Taxonomy, 2009) Özler, Hülya; Cabi, Evren; Us, Ebru; Doğan, Musa; Pehlivan, SevilPollen 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.Öğe Pollen morphology of some Allium L. (Lilliaceae) taxa in Turkey(Bangladesh Journal of Botany, 2010) Özler, Hülya; Pehlivan, SevilPollen 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.Öğe Pollen Morphology of Some Centaurea L., Psephellus Cass. and Cyanus Miller Taxa(ACTA BIOLOGICA CRACOVIENSIA Series Botanica, 2009) Özler, Hülya; Kaya, Zafer; Pehlivan, SevilThe 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.Öğe Pollenmorphology of Hymenosphace and Aethiopis sections of the genus(Lamiaceae) in Turkey Salvia(2013) Özler, Hülya; Pehlivan, Sevil; Celep, Ferhat; Doğan, Musa; Kahraman, Ahmet; Yavru, Ahter FişnePalynological 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.Öğe Taxonomy, morphology and palynology of Aegilops vavilovii (Zhuk.) Chennav. (Poaceae: Triticeae)(African Journal of Agricultural Research, 2010) Cabi, Evren; Doğan, Musa; Özler, Hülya; Akaydın, Galip; Karagöz, AlptekinAegilops vavilovii (Zhuk.) Chennav., a rare species, was collected from Southeast Anatolia, Turkey. During the field studies of the project “Taxonomic revision of Tribe Triticeae in Turkey”, Ae. vavilovii was accidentally recollected from three localities in Şanliurfa and Mardin provinces in 2007 and 2008, respectively. The main objective of this study is to shed light on the diagnostic characteristics of this rare species including its morphological, palynological and micro morphological features. Moreover, an emended and expanded description, distribution, phenology and ecology of this rare species are also provided. A. vavilovii and A. crassa are naturally found in the Southeastern part of Turkey and they share similar morphological features that caused a confused taxonomy. Pollen grains of A. vavilovii are heteropolar, monoporate and spheroidal (A/B: 1,13) typically as Poaceous. However, it generally, prefers clayish loam soils that are slightly alkaline (pH 7.7) with low organic content (1.54%). Although it is a rare species with very narrow area of distribution, very few samples have been represented inex situ collections and the species has not been involved in any in situconservation activities to save its genetic resources in Turkey.
