Identification of some Characteristics of Pollen Grains and Achines by SEM for some Species Belong to Crepis L. Genus (Asteraceae) in Iraq
Year: 2025
Type: conference-paper
Abstract: The microscopic characteristics of pollen grains and fruits of two species of plants belonging to the Asteraceae family was examined by scanning electron microscopy and dissecting microscope. plant samples were collected from different areas of Kirkuk Governorate from February to August 2024. The species were study: Crepis foetida and Crepis capillaries, the current study focused on pollen grain form and Achene ornamentation, Polar and equatorial axis diameter, Length of thorns and diameter of germination aperture, wall thickness and surface ornamentation, the result point to that the aperture number was three tri-porate type, spherical-oblate pollen grain shape in both studied species, wall thickness of pollen grain was (4.5),(2.5) in Crepis foetida and Crepis capillaries respectably, the surface ornamentation was papillae in Crepis foetida species and undulate in Crepis capillaries, the result refer to that the achene deamination was (0.4*0.06) in Crepis foetida species and (0.5*0.2) Crepis capillaries species, Crepis foetida and Crepis capillaries respectably while the form was fusiform in both species,, the study aim to determine the taxonomic characteristics based on pollen grain and Achene morphology.
