The Pollen morphology of 13 taxa 11 of which are endemics belonging to Paronychia Miller (Caryophyllaceae) viz., P. agryloba, P. angorensis, P. arabica subsp. euphratica, P. carica, P. cataonica, P. chinonea, P. condensata, P. davisii, P. dudleyi, P. galatica, P. kurdica subsp. kurdica, P. kurdica subsp. montis-munzur and P. mughlaei from Turkey has been investigated by light (LM) and scanning electron microscopy (SEM). LM observations show that pollen grains are usually radially symetrical, isopolar, pantoporate, polygonal (6-gonal) or polygonal-spheroidal. Tectum is psilate or punctate. Tectal surface sparsely-densely spinulose. T . . .he numbers of pores are between 6 and 12. On the basis of pollen sizes, P. davisii was the biggest pollen type (23.45 µm) and P. kurdica subsp. kurdica (16.2 µm) was the smallest pollen types. According to exine sculpturing, pollen size and spinule numbers per 1 µm2, three pollen types were distinguished. © 2008 Institute of Botany, Slovak Academy of Sciences Daha fazlası Daha az

In this study, the pollen morphology of all Scaligeria DC. species distributed in Turkey were studied with light and scanning electron microscopy for the first time. The aim is to contribute to knowledge of the variation among seven Scaligeria species, which have taxonomic problems, based on pollen morphological characteristics by population analysis. The pollen is radially symmetrical, isopolar, and tricolporate in all examined species. Pollen grains are prolate and subprolate with the polar axes ranging from 18.4 to 37 µm and the equatorial axes from 9.8 to 30 µm. Their polar shapes are triangular, triangular to subcircular, circu . . .lar to subcircular, or triangular to subtriangular. Several types of exine ornamentations have been observed on pollen by scanning electron microscopy. Numerical analysis showed that pore structure, the ratio of P/E, and ornamentation in the polar and equatorial views are most valuable variables for separating the Scaligeria species. All S. lazica taxa were grouped together and S. capillifolia and S. tripartita were the external taxa due to cluster and PCA analysis. © 2018, Turkiye Klinikleri Journal of Medical Sciences.

Scorzonera ketzkhovelii Grossh. (Asteraceae) was recently collected from Yusufeli, Artvin (north-east Anatolia) and it has been reported as a new species record for the flora of Turkey. It is described and illustrated. In addition, its karyological features and pollen morphology are given. © TÜBİTAK.

Pollen morphology of Astragalus L. sect. Onobrychoidei DC. (Fabaceae) in Turkey [Türkiye'deki Astragalus L. cinsi Onobrychoidei DC. (Fabaceae) seksiyonunun polen morfolojisi]

Article | 2009 | Turkish Journal of Botany33 ( 4 ) , pp.291 - 303

The pollen morphology of 45 specimens of 29 species of the genus Astragalus L. of the section Onobrychoidei DC. distributed in Turkey was studied with light and electron microscopies. The pollen is generally 3-colporate. Pollen of the section is prolate, subprolate, and prolate-spheroidal. Size varies, with the polar axis ranging from 23.4 to 42.6 µm and the equatorial axis from 14.3 to 36.4 µm. The outline is elliptic or compressed oval in the meridional section, versus trilobulate and sometimes tetralobulate in the polar optical section. Sculpturing is usually microreticulate, rarely reticulate or rugulate in the meridional optica . . .l section, and psilate and perforate (with irregular or circular perforations) in the polar optical section. © TÜBİTAK Daha fazlası Daha az

Morphological, anatomical and palynological properties of some Turkish Veronica L. species (Scrphulariaceae)

Article | 2007 | International Journal of Botany3 ( 1 ) , pp.23 - 32

In this study, pollen and seed morphology, leaf and stem anatomy of four Veronica L. species (Scrophulariaceae) one of which is endemic (V. multifida) belonging to four Sections [V. persica (Sect. Pocilla), V. beccabunga (Sect. Beccabunga), V. officinalis and V. multifida (Sect. Veronica)] grown in Turkey have been studied on light and scanning electron microscopy. Different and similar features of these species were described. © 2007 Asian Network for Scientific Information.
