Ultrastructure and Pollen Micromorphology of Three Endemic Bellevalia (Asparagaceae) Species in Turkey
(Parlar Scientific Publications (p S P), 2019) Baser, Birol; Firat, Mehmet; Binzet, Riza
The pollen morphology of Bellevalia kurdica Firat, B. siirtensis Firat, B. hakkariensis Firat species (Asparagaceae) was examined using Light Microscopy (LM) and Scanning Electron Microscopy (SEM). The taxa are similar in some aspects, such as pollen size and reticulate exine sculpturing. Pollen grains are shed as monads. They are monosulcate, ellipsoidal, isopolar and bilateral symmetric. The exine is semitectate and the tectum is perforate. Sulcus extends from distal to proximal in some pollen of this genus. Besides, this study is the first report dealing with the palynological features of three endemic Bellevalia Lapeyr. species.
The Pollen Morphology of Pelargonium Endlicherianum and Pelargonium Quercetorum (Geraniaceae) in Turkey
(Pensoft Publ, 2016) Baser, Birol; Firat, Mehmet; Aziret, Akin
The pollen morphology of Pelargonium endlicherianum Fenzl. and Pelargonium quercetorum Agnew. from the family Geraniaceae was examined under light microscopy and scanning electron microscopy. Pollen morphologies are eurypalynous. The pollen grains were tricolporate, prolate-spheroidal and large. Aperture was ectoaperture, colpus was short, and the pores were oblate-spheroidal and large. The exine ornamentations were striate-reticulate and the reticula were heterobrachate. The 2 species are invasive exotics in Turkey.
Pollen and Nutlet Micromorphology of a Rare Species Salvia Kurdica (Lamiaceae) From Turkey
(Pakistan Botanical Soc, 2017) Firat, Mehmet; Baser, Birol; Aziret, Akin
Salvia kurdica Boss & Hohen. ex. Benth. is known from only 2 localities in the territory of southeastern Turkey and northern Iraq. As a part of the fieldwork, this species was collected from Sirnak Province. In this study, the micromorphological characteristics of its pollen grains and nutlets have been investigated using scanning electron microscopy and a light microscope. The pollen grains are hexacolpate, radially symmetrical, isopolar, and suboblate. Its exine sculpturing is bireticulate-perforate. The nutlets are rounded-trigonous in transverse sections, orbicular ovate-oblong in shape, glabrous and slightly tuberculate. This is an invasive species in Turkey.
Pollen Morphological Study on Some Rare Allium L. (Amaryllidaceae) Taxa in Turkey
(Bangladesh Assoc Plant Taxonomists, 2019) Baser, Birol; Firat, Mehmet; Binzet, Riza
The pollen morphology of 10 Allium L. taxa, 6 of which are endemic to Turkey, were investigated in detail by light and scanning electron microscopy. According to LM and SEM, the pollen grains of genera were monad, monosulcate percolate, heteropolar with bilateral symmetry, 25.30 to 53,85 mu m long axis (LA) and 17.55 to 36.86 mu m short axis (SA), the form was prolate (mean of LA/SA ratio 1.30 to 1.70 and in polar view boat-shaped. Three types of ornamentation were determined. Striate-rugulate-perforate type in Allium longisepalum, A. oreophilum, A. anacoleum, A. microspathum, A. shirnakiense, A. purpureoviride and A. armenum, Rugulate-perforate type in A. pervariense and A. gabardagense and Rugulate-reticulate-perforate type in A. arlgirdense. Sulcus membrane ornamentations were rugulate or psilate. The sulcus extends from the distal to proximal ends in A. anacoleum, A. arlgirdense and A. pervariense. The present study on some Turkish species of Allium showed that several morphological pollen characters may possess taxonomical value.
