AB  - Buaraştırma ile Türkiye’de yayılış gösteren Centaureacinsine ait morfolojik olarak birbirine oldukça yakın karakterlere sahip C. lycopifolia ve C. cheirolopha taksonlarının anatomik, palinolojik ve akenmikromorfolojik özellikleri ayrıntılı olarak ortaya konulmuştur. Anatomikaraştırmalar, parafin yöntemi ya da el ile alınan kesitlerin kullanılmasıylagerçekleştirilmiştir. Türlerin anatomik yapılarında, kök korteksinde C.cheirolopha’nın sklerenkimatik hücreler ihtiva etmesi ile iki türünbirbirinden farklılık gösterdiği gözlenmiştir. Gövdelerden alınan eninekesitler, tipik dikotiledon anatomik yapısını yansıtmış olup, türlerinsilindirik yapıda korteks tabakası ile kollenkimatik hücreler ihtiva ettiğitespit edilmiştir. Gövdedeki iletim demetlerinin sıra sayısı C. lycopifolia’da iki iken, C. cheirolopha’da tektir. Yaprakanatomisinde mezofil dokusu her iki takson içinde ekvifasiyal olarak tespitedilmiştir. Midripteki iletim demet sayısı yine türler arasında farklılıkgöstermekte olup, C. cheirolopha’daüç, C. lycopifolia’da tektir.İncelenen türler, monad, izopolar, prolat-sferoidal ve trikolporat polentanelerine sahiptir. Her iki takson için ekzin skülptürü skabrat-perforatolarak gözlenmiştir. Araştırılan taksonların her ikisi de kahverengi-samanrenkli akenlere sahip fakat C.cheirolopha’da belirgin krem çizgiler mevcuttur. Pappustaki kılçıkşekillerinin taksonlar arasında açık şekilde farklılık gösterdiğigözlemlenmiştir. Sonuç olarak, C.lycopifolia ve C. cheirolophataksonlarının anatomik, palinolojik ve mikromorfolojik karakterlerinintaksonların ayrımına destek sağladığı ortaya konulmuştur.

N2  - With this study, C.lycopifolia and C. cheirolophawhich are close species with their anatomical, palynological and achene micromorphological traits were presented in detail. The anatomical researches havebeen carried out by paraffin method or using handmade sections. In theanatomical structures of taxa, it was observed that C. cheirolopha contains sclerenchymatic cells and that two speciesdiffered from each other. The cross sections taken from stems were reflectedthe typical dicotyledonous stem anatomical structure and were determined thatspecies have cortex parenchyma with cylindrical shaped and collenchymaticcells. The rows of vascular bundles in stem are two in C. lycopifolia as one in C.cheirolopha. Mesophyll were detected as equifacial in both species inleaves. The numbers of vascular bundles in midrib are variable between studiedspecies and were three in C. cheirolophaand one in C. lycopifolia. Thestudied taxa have monad, isopolar, prolate-spheroidal and tricolporate pollengrains. For two examined species, exine sculpture were observed asscabrate-perforate. Both of examined species have brown-straw color achene but C. cheirolopha has also distinct creamlines. The shapes of pappus of spines were observed distinctly different inspecies. As a conclusion, the characteristics of anatomical, palynological andmicro morphological in C. lycopifoliaand C. cheirolopha have been revealedsupporting the separation of species.
