Online published on 24 July, 2018. Abstract The study examined the precise The micromorphology of pollen grains characteristics of some species belonging to the Cyperaceae family, which included four species of Cyperus L. which it: C.difformis, C. rotundus, C.odoratu and C.alternifolius and one species of genre Bolboschoenus maritimus. The samples were collected from the banks of the Diwaniyah River and specifically (Sunni area, Dagara district, Diwaniyah district and al-Sudair district) During the autumn and winter season Beginning mid-October 2016 and the end of February 2017. The study examined the Micromorphology of the pollen and showed variations, which helped to isolate the taxa at the level of genera and species The study went on the shape and size of the polar and Equlature view and wall thickness, using the Light Microscope(LM) besides the number of aperturate and length of the grooves and the shape of the surface decoration using the Scanning Microscope Electronic (SEM) The results showed that there was a variance of most of the above-mentioned traits. At the level of the shape, the pollen showed that the pollen was in two shapes: Oblate Spheroidal and Sub Oblate. As for size, B. maritimus recorded the largest size of the pollen while the species C.difformis The smallest size also gave the number of pores a taxonomic importance that cannot be ignored as it was possible to divide the species into two groups and The prevailing model was (Tetracolporate). The surface decoration showed clear variations, and all species were isolated, which increased the taxonomic importance of this characteristic. The thickness of the wall did not appear to be of great importance for the separation of the species. The present study concluded that five species of Cyperaceae family were diagnosed along the Diwaniyah River. Two species were recorded for the first time on the river: C.odoratu and C. alternifolius Top Keywords Cyperaceae.Cyperus L. Bolboschoneus maritimus. Micromorphological pollen grains. SEM. Top |
