Gibberellic acid (Gibberellins) are plant hormones. When purified, it is a white to pale yellow crystalline powder, soluble in ethanol and sparingly soluble in water. Germination is the process by which the dormant embryo wake up, grow out of the seed coat and establishes itself as a seedling. 36 viable seeds were soaked in different concentrations (2. 5 mg/L, 5.0 mg/L and 7.5 mg/L) of gibberellic acid for 24 hours and sowed. 10 days after, the number of germinated seeds were determined. The result shows that the rate of seed germination is proportional to concentration of the gibberellic acid. The seeds treated with high concentration of gibberellic acid (7.5 mg/L) has the highest number of germinated seeds compared to those of lower concentrations of gibberellic acid whereas the gibberellic acid treated seeds was found to be higher than untreated control group (0.0 mg/L).
