Pollen morphology of sections Siphonomorpha and Lasiostemones of the genus Silene from Turkey

TURKISH JOURNAL OF BOTANY (2011)

Kemal Yıldız Mehmet Yaşar Dadandı Ersin Minareci Ali Çırpıcı

The pollen morphology of 16 taxa belonging to the sections Siphonomorpha Otth and Lasiostemones Boiss. from the genus Silene L. (Caryophyllaceae) was examined via scanning electron microscopy (SEM). Pollen types among all of the examined taxa were spheroidal; ornamentations were generally microechinate-microperforate (punctate), but perforate in Silene viridiflora L.; structures were mostly tectate but were observed to be semitectate only in S. viridiflora; the highest pore numbers were found in S. fruticosa L. and S. viridiflora; the lowest pore numbers were those of S. gigantea L. subsp. rhodopea (Janka) Greuter and S. marschallii C.A.Mey.; and interpore distance was greatest in S. gigantea subsp. rhodopea and smallest in S. amana Boiss. The widest perforation was observed in S. Viridiflora, whereas the lowest value was observed in S. olympica Boiss. As a result of these detailed examinations, some Silene species with significant taxonomic problems were reviewed in terms of palynology, and suggestions are provided about their positions. S. viridiflora was determined to be the taxon with the most different pollen morphology according to general characters. According to pore number and perforation, the most advanced taxon was S. Viridiflora, while the most primitive taxa were found to be S. olympica, S. gigantea subsp. rhodopea, and S. olympica.

Morphological, palynological and phylogenetic relationships of <i>Glaucium</i> Mill. in Turkey

Bangladesh Journal of Plant Taxonomy (2019)

Fatma MUNGAN KILIÇ Kemal Yıldız Muhammet Burak Batır Murat KILIÇ İlker Büyük

Glaucium taxa were investigated in terms of their morphological, palynological and phylogenetical characteristic. The results of this study show differences between the taxa in some of these characteristics, especially in micromorphology and formation of clades in phylogenetic trees based on the matK and ITS3-6 DNA sequence data. Based on the findings of the molecular analyses supported by morphological data (stem’s trichomes),the genus Glaucium of Turkey was divided into subsections Glabrousae and Pubescentae.

Karyological Studies in Some Species of the Genus Silene (Caryophyllaceae)

CYTOLOGIA (2009)

Ersin Minareci Kemal Yıldız Ali Çırpıcı

Karyology of the 6 Silene species from Turkey was investigated. Diploid chromosome numbers and the basic chromosome number of the studied taxa were obtained as 2n=24 and x=12 respectively. The karyotype analysis of S. viscosa, S. eremitica, S. skorpilii and S. confertiflora were carried out for the first time. Also the chromosome numbers of S. eremitica and S. confertiflora were determined for the first time. The largest chromosomes were observed in S. otites and the smallest ones were observed in S. viscosa. S. otites shows the highest A1 index. S. skorpilii represents the highest interchromosomal asymmetry coefficient (A2). The karyologic results of the study and the analysis of chromosomal morphology of each taxon were shown as tables.

Asperula pseudochloranthavar.Antalyensis comb, et stat nov.(Rubiaceae)

Annales Botanici Fennici (2010)

Ersin Minareci Kemal Yıldız

Asperula pseudochlorantha Ehrend, and Asperula antalyensis Ehrend, from Turkey were described in 1958. General characteristics, seed structure and micromorphology, pollen measurements and other pollen characteristics were examined to determine the taxonomic status of these taxa. Morphologically, the two taxa cannot be easily distinguished, and the seeds and pollen grains are similar. The chromosome number is 2n = 22 for both taxa. Based on morphological, palynological and cytological similarities, and the fact that both taxa are found in the same habitats, we propose that A. antalyensis should be recognized as A. pseudochlorantha Ehrend, var. antalyensis (Ehrend.) Minareci & K. Yıldız, comb. et stat. nov.

Seed morphology of some Silene L. (Caryophyllaceae) speciescollected from Turkey

TURKISH JOURNAL OF BOTANY (2015)

Mehmet Yaşar Dadandı Kemal Yıldız

The seed micro- and macromorphology of 39 Silene taxa were studied by stereomicroscope and scanning electron microscope. Quantitative (9) and qualitative (11) values of seed characters vary greatly both within and between taxa. The tree topology of UPGMA based on quantitative values does not supported the traditional relationship. Therefore, we concluded that seed characters of Silene alone cannot be used to describe taxa without detecting the full range of intra- and intertaxon variation of those characters.

A palynological investigation of endemic taxa from Northern Cyprus.

Pakistan Journal of Botany (2009)

Kemal Yıldız Salih Gücel Mehmet Y. Dadandı

Palynology of 19 endemic plant taxa belonging to 9 families distributed in North Cyprus was investigated by both light (LM) and scanning electron microscopy (SEM). The pollen grains were measured and their aperture characteristics and surface ornamentation determined. The systematic positions of the taxa as well as the genera they belonged to were investigated according to the data obtained. The largest pollen grains were found in Salvia veneris Hedge and the smallest ones in Onosma caespitosum Kotschy. The pollen type was generally termed trizonocolpate, pollen shapes spheroidal, prolate, subspheroidal, perprolate, supraprolate, pollen structure tectate and semitectate, and ornamentation scabrate, striate, microechinate, microperforate, reticulate, microreticulate, bireticulate, psilate and rugulate.

Taxonomical study of seeds and fruit micromorphology of the Geranium (Geraniaceae) species in the Thrace region of Turkey (Europe)

Phytologia Balcanica (2018)

İsmail Gökhan Deniz Kemal Yıldız Ali Hikmet Çırpıcı

The seed and mericarp micromorphology of 13 naturally growing Geranium species (G. lucidum, G. purpureum, G. robertianum, G. rotundifolium, G. molle, G. pusillum, G. divaricatum, G. columbinum, G. dissectum, G. tuberosum, G. asphodeloides, G. sanguineum, and G. pyrenaicum) in Thrace have been studied by scanning electron microscope. According to the analysis, seeds are generally ovate-elliptic, smoothsurfaced and faveolate, and only the seeds of G. divaricatum and G. tuberosum are reticulate. Mericarps are usually without the strand of fibres, callus and prong at the base, the rostrum is generally 10–20mm long -minimum 5–8mm long (G. pusillum), maximum 15–32mm long (G. sanguineum). These results have shown that the species can be identified according to their mericarp and seed surface characteristics.

A Palynological Investigation on Silene L. (Caryophyllaceae) Species Distributed in North Cyprus and West Anatolia

Kemal Yıldız

In this study, the palynology of Silene sipylea LO. Schwarz, S.fabaria (L.) Sibth.& Sm., S.tenuiflora Guss., S.lydia Boiss. distributed in West Anatolia (B1, C1, C2) as well as S.discolor Sibth.& Sm. and S.colorata Poir. var.colorata distributed in North Cyprus was investigated. Pollens taken from the mature flowers of the species were according to the method of Erdtman (1); and then pollen diameter, pore diameter, distance between two pores and exine values were measured; the number of pores determined; and micrographs taken by light microscopy included in the study. In addition, significant palynological characters of the species were presented in the table form. The systematic position of the species with respect to palynological data was discussed. Unlike other species, S.tenuiflora pollens are reticulate, whereas those of the other Silene species that have been examined are spheroidal, tectate, microechinate and microperforate. The largest pollens are found in S.sipylea, while S.lydia had the greatest number of pores.
