The College of Education for Pure Sciences is discussing a doctoral thesis on the effect of spraying with nano-nitrogen and potassium on some physiological and biochemical characteristics of chrysanthemum plants.
The Department of Life Sciences at the College of Education for Pure Sciences at the University of Karbala discussed a doctoral thesis entitled “The Effect of Spraying with Nano-Nitrogen and Potassium on Some Physiological and Biochemical Traits of Chrysanthemum (Calendula officinalis L.) Under Water Stress Conditions.”
By student Aqeel Abdul Abbas Abdul Zahra Al-Sudani Under the supervision of Prof. Qais Hussein Abbas Al-Samak
The study aimed to determine the response of chrysanthemum plants to spraying with nano-Nitrogen and Potassium and its impact on their phenotypic, physiological, and biochemical traits. It also aimed to study the dual and triple interactions of the studied factors to obtain the optimal treatments for improving the growth and productivity of chrysanthemum plants grown under different irrigation water levels.
The study concluded that the interactions between the three studied factors significantly improved the phenotypic, physiological, and biochemical traits of the studied plants. The study reinforced the importance of spraying with nano-materials in improving the conditions of plants exposed to water stress, as the oil extract plays a distinct role in chemical studies in identifying the nature of the materials. Chemical metabolism contributes to many important biological and physiological activities.
The study recommended the necessity of spraying nano nitrogen at a concentration of 4 ml L-1 and nano potassium at a concentration of 4 g L-1 to reduce damage caused by water stress. It also recommended expanding the use of other nanomaterials under various abiotic stresses to determine their impact on plants. The study also recommended studying the effect of chemical compounds extracted from oils and other extracts on microorganisms such as bacteria, fungi, and others, to determine their sensitivity to the extract and determine their biological activities.
