Under the supervision and attendance of the Dean of the College, Dr. Yusra Majeed Al-Shaker, the discussion of the master’s thesis entitled “The efficiency of gamma rays in producing environmentally friendly nanoparticles from the callus of the blessed purslane plant Portulaca oleracea and testing its efficiency in bioremediation” was held this morning, Wednesday, February 26, 2025, for the student Nour Ali Najmuddin Muhammad Ali in the discussion hall of our college.

The discussion committee was headed by Professor Dr. Muhammad Ibrahim Khalil and the membership of each of
Assistant Professor Dr. Muhammad Mahmoud Younis and Assistant Professor Dr. Hekmat Mustafa Musayyib and the membership and supervision of each of Assistant Professor Dr. Rahab Abdul-Jabbar Hamid and Professor Dr. Laith Ahmed Najm.

The study included the effect of gamma rays on the vegetative growth of purslane seedlings, the study of the effect of these rays on the creation of callus farms, and measuring the effectiveness of the stimulating role of gamma rays on primary and secondary metabolism compounds, in addition to studying the effect of rays on causing mutations in purslane plants and the production of environmentally friendly nano-tools from purslane callus. The study aimed to find an optimal sterilization method that increases the germination rates of Portulaca oleracea seeds after exposing them to gamma rays, and to study the effect of gamma rays on the vegetative and root system of Portulaca oleracea seedlings, and to demonstrate the role of gamma rays in stimulating the initiation and growth of callus, as well as studying the effect of gamma rays on the accumulation of primary metabolism (protein) and secondary metabolism (active compounds), and to investigate the effect of gamma rays in the production of new genetic patterns, in addition to producing environmentally friendly nano-supplements from Portulaca callus and evaluating the effect of the pH function on production, and finally studying the efficiency of the nano-supplement in the inhibitory activity of pathogenic bacteria. The study recommended studying the effect of gamma radiation activity and studying its effect on seed germination rates and vital growth indicators of seedlings and callus farms of the blessed purslane plant Portulacaoleracea and various other plants, studying the effect of various environmental factors other than the pH indicator on the production of nano-equipment from callus farms, and studying the application of environmentally friendly and vegetatively manufactured silver nanoparticles in other fields of study, for example, inhibiting the growth of cancer cells and using them as carriers and carriers for drugs, and finally using and exploiting plant tissue culture in general and callus farms in particular to manufacture nano-equipment particles in general locally as fast, continuous and environmentally friendly cell factories and using these particles in all scientific and applied fields.
