PH.D. Dissertation Viva in the College of Education for Pure Science entitled “Intrinsic and heterogeneous allelopathic evidence between fenugreek and wheat plants treated with ascorbic acid grown in saline soil”The College of Education for Pure Science, University of Mosul, has done the PH.D. Dissertation Viva entitled “Intrinsic and heterogeneous allelopathic evidence between fenugreek and wheat plants treated with ascorbic acid grown in saline soil “,On Tuesday, June 21, 2022, the College staff including the respected Dean of the College, Assistant Professor Dr. Qais Ismail Ibrahim, the Honorable Scientific Associate and Administrative Associate, the Honorable Head of the Department of Biology, and a number of the college’s teachers were attended the viva. This study, presented by the PH.D. Student Hanan Ameer Abdullah Al Rashedy in the Department of Biology was conducted at the University of Mosul / College of Education for Pure Sciences / Department of Biology. It includes conducting three laboratory experiments. The first experiment included the effect of the water extract of wheat and fenugreek plants on the germination and growth of fenugreek seedlings.The second experiment was conducted in the wire house for two consecutive seasons in the agricultural season 2019-2020. It included the cultivation of wheat plants (Aba’ type) and fenugreek (Indian type) in soils treated with different levels of salinity (0, 50, 100, 150) mmol / liter of sodium chloride with spraying the shoots with concentrations of ascorbic acid (0, 100, 200) ppm. The effect of these factors was shownin some physiological traits and the second season, the experiment was conducted in the wire house in the agricultural season 2020-2021.It included the effect of soils previously planted with fenugreek and wheat plants and treated with different levels of salinity and ascorbic acid on some physiological, chemical and biochemical characteristics and the growth of fenugreek plants. The results were analyzed statistically, the results can be summarized as follows: Chemical analysis results:The results showed that there were differences in the concentration of phenolic compounds in the alcoholic extract of fenugreek seeds grown in the second season and grown in soils containing fenugreek residues and wheat grown in the first season, which were treated with sodium chloride and ascorbic acid The Viva committee was chaired by Prof. Dr.Shakir Mahdi Salih from University of Tikrit / College of Agriculture and the membership of Prof. Dr.Janan Saeed Abdul khaliq / university of Mosul / college of science, Prof. Dr. Faeq Hassan Ali University of Mosul / Science Botany, Prof. Dr.Muthanna Jasim Mohamed / university of Mosul / college of Education for pure sciences.
