Abstract

Cousinia, Asteraceae’deki en büyük cinslerden biridir, Güneybatı ve Orta Asya’da 700 tür içermektedir. Cousinia seksiyonu Türkiye’de 23 tür ile temsil edilmektedir. Cousinia’nın taksonomisi tartışmalıdır. Anatomi ve polen morfolojisinin kullanılması, türlerin tanımlanması ve sınırlandırılması için faydalı bir araç olabilmektedir. Bu nedenle bu çalışmada Cousinia aucheri DC’nin anatomik, palinolojik ve aken mikromorfolojik özelliklerini araştırmayı ve Cousinia’nın sistematiğine katkı sağlamayı amaçladık. Anatomik çalışmalar için gövde, yaprak ve orta damar kesitlerinde parafin yöntemi kullanıldı. Palizat parankima sayısı, orta damarın şekli, damar demetlerinin sayısı ve düzenlenişinin önemli taksonomik bilgiler sağladığı belirlendi. Polen preparatları Wodehouse yöntemine göre hazırlandı. Polen taneleri trikolporat aperture ve verrukat süslemeye sahip olduğu belirlenmiştir. Ayrıca akenlerin morfolojik ve mikromorfolojik özellikleri araştırılmış ve yüzey süslemelerinin retipilat olduğu tespit edilmiştir.

Anatomical, Palynological and Micromorphological Studies on Cousinia aucheri, an Endemic Species

Abstract

Cousinia is one of the largest genera in the Asteraceae and includes 700 species in Southwest and Central Asia. The section Cousinia is represented by 23 species in Turkey. The taxonomy of Cousinia is contentious. The use of anatomy and pollen morphology can be a useful tool for species identification and delimitation. Therefore in this study, we aimed to investigate the anatomical, palynological and achene micromorphological characteristics of Cousinia aucheri DC. and to contribute to the systematics of Cousinia in this study. Paraffin method was used on stem, leaf and midrib sections for anatomical studies. It was determined that the number of palisade parenchyma, the shape of the midrib, the number and arrangement of the vascular bundles provide important taxonomic information. The pollen slides were prepared according to Wodehouse method. The pollen grains have tricolporate aperture and verrucate ornamentation. Furthermore, the morphological and micromorphological features of the achenes were investigated and their surface ornaments were found to be retipilate.
