Seed dormancy is the most limiting factor for some plants propagation. Dormancy allows seeds to separate from their mother plant and survive dispersal, over distance and time before growth recommences. This study was aimed to determine the effect of three pre-treatments on breaking the seed dormancy of Adansoniadigitata L., a multi-purpose and indigeneously endangered tree. The study was carried out in the greenhouse of the Department of Biological Sciences, Federal University Dutsin-Ma, Nigeria. The three pre-treatments are: soaking in hot water (100C) for 5, 10, 15 and 20 minutes; and soaking in sulphuric acid (H2SO4) and Hydrochloric acid (HCL) concentrations (100%, 75%, 50% and 25%) for 5, 10, 15 and 20 minutes. Untreated intact seeds have served as control. These were laid out in a Complete Randomized Design (CRD) with three replications. Data were collected on Germination Percentage (GP), Germination Rate (GR), Day of Emergence (DOE) and the Average Seedlings Height (ASH).The result showed that earliest mean days of emergence (7days) was observed in seeds subjected to hot water treatment at 15 minutes. It also showed the highest rate of germination and percentage 6(100%). On the other hand, the effect of acids (H2SO4and HCL) pre-treatments on the seeds gave a fair result (16.66 to 33.33%). Untreated seeds did not germinate at all. All the pre-treatments used in the study were found to be effective. However, soaking of seeds in hot water (100oC) pre-treatment for 15 minutes is therefore recommended for breaking the seed dormancy of A. digitata.
