Effect of Gibberellic Acid and Indole 3-acetic Acid on Improving Growth and Accumulation of Phytochemical Composition in Balanites aegyptiaca Plants

Seeds of Balanites aegyptiaca were soaked in Gibberellic acid solutions (0, 50,100, 150, ppm) and Indol 3-acetic acid solutions (IAA) (1000, 2000, 3000 ppm) for 14 h to study their effects on the germination percentage, plant height, number of branches and leaves, total chlorophyll content, dry weight and protein, carbohydrates, alkaloids, tannins, saponins and phenol contents. The study resulted in significant increases in most of these parameters mentioned previously. In contrast, a decrease in phenols content was found using all concentrations of both GA3 and IAA. The concentrations of 50 ppm of GA3 and 2000 ppm of IAA gave the best results by increasing the growth and phytochemical composition.
