The germination success of seeds placedunderthecanopiesofA.tortilis(N=20),Gardenia ternifolia Schum. It can be suggested that this increased germination rate occurs because the boiling water, by which the seeds were soaked in, breaks down the hard coating on the outside layer of the seed, thus allowing the seedling to penetrate through the coating and begin the germination process. A bean seed will grow into a bean plant. & Thonn. In the natural environment, the hard coating of the Acacia seeds may be broken down due to a bush fire allowing the plant to begin rejuvenation (Hill & French 2003). Germination experiment. Specifically, the boiling water treatment showed maximum seeds swelling while the majority of oven treated and The data collected, highlights how the control group, which was left untreated with boiling water had a near perfect germination (%) with 7 out of 8 seeds germinating while the final group of Acacia decurrens heated using an oven, had a total of 1 seed out of 8 germinating (Table 1).
