Bu çalışmada Türkiye’de yayılış gösteren Petrorhagia (Ser.) Link (Caryophyllaceae) cinsine ait türlerin polen
yapıları mikromorfolojik yöntemle, taramalı elektron mikroskobu (SEM) kullanılarak incelenmiştir. Cins Ülkemizde 4
türü endemik olmak üzere 12 türle temsil edilmektedir. Bu çalışmada incelenen türler ve endemizm durumları:
Petrorhagia lycica (P.H.Davis) P.W.Ball. & Heywood (endemik), P. cretica (L.) P.W.Ball & Heywood, P. alpina
(Hablitz) P.W.Ball. & Heywood subsp. alpina, P. alpina (Hablitz) P.W.Ball. & Heywood subsp. olympica (Boiss.)
P.W.Ball. & Heywood, P. saxifraga (L.) Link, P. pamphylica (Boiss. & Balansa) P.W.Ball. & Heywood (endemik), P.
peroninii (Boiss.) P.W.Ball. & Heywood (endemik), P. prolifera (L.) P.W.Ball. & Heywood, P. dubia (Raf.) G.López &
Romo. Genellikle taşlık alanlar, tarla ve yol kenarları gibi habitatlarda yayılış gösteren cinsin türleri 2003-2007 yılları
arasında proje kapsamında toplanılmıştır. Çalışma sonucunda Petrorhagia cinsi polen şeklinin sferoid olduğu ve türlerin
tamamında polenlerin porlu (poliporat) yapıda oldukları bulunmuştur. Ancak türler arasında; polen büyüklükleri, por
sayıları, polen ve operkulum ornemantasyonları farklılıklar göstermektedir.

In this study, the pollen structure of species belonging to the genus Petrorhagia (Ser.) Link (Caryophyllaceae)
in Turkey with micromorphological method which is scanning electron microscopy (SEM) were examined. The genus is
represented by 12 species, 4 of which are endemic. Species examined in this study and their endemism status: Petrorhagia
lycica (P.H.Davis) P.W.Ball. & Heywood (endemic), P. cretica (L.) P.W.Ball & Heywood, P. alpina (Hablitz) P.W.Ball.
& Heywood subsp. alpina, P. alpina (Hablitz) P.W.Ball. & Heywood subsp. olympica (Boiss.) P.W.Ball. & Heywood,
P. saxifraga (L.) Link, P. pamphylica (Boiss. & Balansa) P.W.Ball. & Heywood (endemic), P. peroninii (Boiss.)
P.W.Ball. & Heywood (endemic), P. prolifera (L.) P.W.Ball. & Heywood, P. dubia (Raf.) G.López & Romo. Petrorhagia
species, which generally spread in habitats such as stony areas, fields and road sides, were collected in the project between
2003-2007. As a result of the study, it was found that the pollen shape of the genus was spheroid and the pollen species
were porous in all species. However, among the species; pollen sizes, number of pores, pollen and operculum
ornamentations show differences.
