Discussing a PhD thesis

The Department of Biology Sciences at the College of Education for Pure Sciences / University of Karbala discussed a doctoral thesis entitled (The effect of chelated and metallic nanoscale iron and the method of addition on growth and some chemical compounds and anatomical properties of Moringa oleifera Lam.), To the student (Jawad Kazem Obaid Al-Hujairi), on Sunday coincidence December 20, 2020, and in the discussion room of the Department of Life Sciences, under the supervision of Prof. Abdoun Hashem Alwan Al-Ghanimi, and Prof. Dr. Nepal rainy cruiser Karawi
The aim of the discussion was: To study the effect of adding chelated iron and metallic iron nan fertilizer and the method of adding it by foliar fertilization and ground fertilization on the vegetative, physiological and anatomical growth characteristics and some vitamins and active substances of Moringa oleifera Lam. . Among the conclusions of the study – the effect of foliar or ground spraying with chelated and metallic nanoscale iron led to a significant increase in the characteristics of vegetative and root growth, enzymatic and non-enzymatic antioxidants, active substances in plant leaves, anatomical properties of leaves and stems, and the concentration exceeded 360 mg. L-1 of nanoscale iron and iron. The effect of ground fertilization was different from foliar fertilization, and the ground additive was the most effective in most of the studied traits in Moringa oleifera plant, and the use of nanowire and mineral iron fertilizers alone at different levels had a significant effect on the vegetative and physiological growth characteristics and active substances, especially when Add concentrate 360 ​​mg. L -1
The effect of triple interference on most of the vegetative growth characteristics, mineral and biochemical content, and the anatomical features of leaves and stems of the plant did not affect leaf area rates, absolute and relative growth, root growth characteristics, chlorophyll content, and the activity of enzymes, flavonoids and G-Sitosterol in leaves. The discussion resulted in several recommendations: – We recommend setting up extension courses for farmers to spread the cultivation and propagation of Moringa oleifera in Iraq due to its nutritional, medicinal and economic importance and to encourage its production on a commercial scale. Interest in studying the rest of the other micronutrients, knowing the response of the Moringa oleifera plant, determining the efficient concentrations of them, conducting studies that include micronutrients and macronutrients, and determining the best combinations of them for Moringa plants on the field scale.
The composting combination can be recommended to use 360 ​​mg-liter-1 nano-iron and 360-mg-liter-1-metallic iron to obtain the best vegetative properties, mineral content and active compounds.
Estimating the effectiveness of enzymatic antioxidants, non-enzymatic antioxidants and other active substances that have not been studied in our research. Conducting genetic and anatomical studies of other varieties of Moringa plant treated with nanowire and metallic iron to find out their effect on these traits. Conduct an analytical study to find out the active substances and their concentrations in flowers and roots. The plant has different concentrations of chelated iron and metallic iron. The thesis was accepted by the discussion committee.
