Title: Preparation and Application of Some Nitrogenous Derivatives of Gum Arabic as Plant Growth Promoters
Author: Mudawi, Hassan Ali; Abdelrahim, Saifeldin Mohamed Khair; Abdelhamid, Yassin Mohammed
Abstract: The study was conducted to determine the effect of adding gum and some of their nitrogenous derivatives to the Winka seeds. Derivatives of arabic acid, arabamide, ammonium arabate, derivative of high protein and derivative of low protein were prepared. The physiochemical parameters for these derivatives were examined and comparisons were carried out. The results showed that there were no significant differences between the derivatives in specific rotation and in emulsifying stability. However, there were significant differences between these derivatives in pH, except between arabamide and aminoarabate with arabic acid. There were significant differences between all derivatives in nitrogen (protein content). These derivatives were added in concentration of either 5% or 10% to pots containing Winka seeds while to other pots only water was added. The experiment duration was 10 weeks. The results showed that there was significant difference in the number of plant leaves which were treated with these derivatives. The highest number of leaves was reported for plants treated with arabic acid (C = 5% and C = 10%). There was significant difference in plant height, the highest plant height was reported for plants to which arabic acid (C= 5% and C = 10%) were added. The shortest height was reported for plant to which only water was added. Concerning the dry matter production, significant differences between these treatments were noticed. The highest value was reported for plants which were treated with arabic acid (C = 5% and C = 10%). The lowest value was reported for plant to which only water was added.
