Pollen morphology of twenty three species of Allium L. (Amaryllidaceae) species from Turkey

The pollen morphology of 23 Allium L. species, grown in Turkey, belonging to the sections; Rhizirideum, Schoenoprasum, Cepa, Molium, Brevispatha, Scorodon, Acanthoprason and Melanocrommyum, were investigated by LM (light microscopy), TEM (transmission electron microscope), SEM (scanning microscopy). This paper presents detailed morphological features are given for these taxa. Common characteristics species ellipsoidal heteropolar, bilateral symmetry; grains shed as monads. They monosulcate (extended sulcate types) monosulcate-operculate. sculpturing exine, membrane ornamentation, lumina shape, sulcus with a fragmented operculum found be characteristic separating species. Based on properties three main types determined different exine sculpturing. structures observed micrographs, striate­perforate, striate­regulate-perforate regulate-perforate. Sulcus ornamentations psilate, psilate-perforate, rugulate is semitectate tectum perforate. Columellae simplicolumellate. Bangladesh J. Plant Taxon. 30(1): 1-19, 2023 (June)
