College of Education for Pure Sciences Discusses a Doctoral Thesis on an Anatomical and Taxonomic Study of Species of the Cyperaceae Family in Iraq

PhD Thesis Discussion

 Department of biology at the College of Education for Pure Sciences/University of Karbala discussed a doctoral thesis entitled (Anatomy and Taxonomic Study of Species of the Sadia family Cyperaceae in Iraq) by the student (Basma Aziz Hamid Al-Jubouri) and under the supervision of (Prof. Dr. Majid Khalif Kamer), and (Asst. Prof. Dr. Nepal Umtair Al-Karaawi.
The objective of the thesis was a phenotypic study of the reproductive parts and fruits of the species under study, an anatomical study of the vegetative parts, which included (the cuticle of leaves, stems and transverse sections of leaves and stems) for the species under study, an anatomical study of the flower parts (the caps) of the species under study, a study of the characteristics of pollen and its phenotypic characteristics for the species under study. studying.
Among the conclusions presented by the thesis, it was found from the study the extent to which the anatomical characteristics showed by the genera and species of the Saadia family under study, especially with regard to the characteristics of the epidermis and transverse sections of leaves and stems and the skin of the flower parts, which contributed in many aspects to support the separation between the different taxonomic units studied, and thus the Many of them are reliable traits in diagnosing these units, and they are no less important than phenotypic traits, even if they are not visible. The importance of the phenotypic characteristics of the flowering parts and the fruits of the species, as many of them reported in the diagnosis of taxonomic units and the distinction between them.
The researcher recommended the need to expand phenotypic studies to include all plant parts, especially those that were not included in the current research, using scanning electron microscopy of the surfaces of the flowering and vegetative parts, pollen and fruits, using modern techniques, especially molecular studies, such as PCR techniques and Restriction Fragment Length Polymorphism (RFLP). Which reflects the genetic differences in the genes of plants, thus helping to distinguish and classify and thus isolate the genotypes that are close to each other, and the need to carry out chemical studies, which also show the extent of convergence between the taxonomic ranks and the isolation and classification of effective chemical compounds, especially that the studied species of the family are of medical importance and contain medically effective compounds. The student received an excellence grade.
