PALYNOLOGY OF TAXA BELONGING TO ANTHEMİS L., AND COTA J. GAY GENERA THAT GROW AT ÇANAKKALE PROVINCE

Abstract

Pollen morphology of Anthemis L. and Cota J. GAY taxa that were collected from various localities at Çanakkale province in 2015 are examined in this article. Wodehouse (1935) and Asetoliz (1960) methods were used in this study. Pollen morphologies of 5 taxa (2 species and 1 subspecies of Anthemis L. genusand 1 species and 1 variety of Cota J. GAY genus) were identified according to LM and SEM. Pollen grains are monad, tricolparate, isopolar and they have radial symmetry under light microscope. Pollen grains are in the shape of suboblate and oblatae-spheroidae. Amb are in the shape of semiangular-circular and interhexagonal-subtriangular. Ornamentation of Anthemis L. and Cota J. GAY are echinate-reticulate under light micrograph. Also, in SEM micrograph, ornamentation of Anthemis L. and Cota J. GAY genera are echinate-microperforate. Morphological properties of pollen grains belonging to Anthemis L. and Cota J. GAY have some similarities. Sexine2 is more apparent in pollen grains of Cota genus. Base length of spine is longer than spine length in both genera. In addition, exines of Anthemis L. and Cota J. GAY prominently have laminarstructure. Palynological properties of Anthemis auriculata Boiss., Anthemis tomentosa L. subsp. tomentosa taxa are examined for the first time in this study. Also, according to type records in Flora of Turkey, Anthemis cotula L. is collected from Çanakkale for the first time.
