| Özet |
| Centaurea is one of the largest genus of the familyAsteraceae. Turkey is one of the distribution areas of this genus. This genusrepresented with 194 taxa in Turkey, which 105 of them are endemics. In thisstudy, pollen morphology and achene micro and macro morphology of 5 taxabelonging to Centaurea (C. iberica, C. virgata, C. cheirolopha, C.urvelli subsp. urvelli, C. solstitialissubsp. solstitialis) wereinvestigated. The aim of the study was to determine taxonomic value of pollenand achene micro features.Pollengrains of Centaurea taxa observed asisopolar, with tricolporate aperture and subprolate and prolate-spheroidalpollen shape. Polar axis ranges between 30.4-49.9 µm while equatorial axisbetween 25.7-41 µm. Theachene shape was observed as ovoid and oblong in studied taxa. SEM showed thatthe achene surface had a striate sculpture and was depressed on both lateralsurfaces, without rare hairs. The microcharacters contain polar axis, equatorial axis, pollen shape, pollen surfaceornamentation, intine and exine thickness, achene length, Pappus length, achenesurface ornamentation was determined as important features for systematics oftaxa. |
