AB  - A study on effect of various pretreatment techniques on germination of <I>Acacia senegal</I> was conducted in the Teaching and Research Farm of Faculty of Agriculture, Delta State University, Asaba Campus. These seeds were subjected to pretreatments in water at 60 and 28ºC; dilute sulphuric acid (H<SUB>2</SUB>S04) and storage in refrigerator at 0ºC. Under warm water experiments the following treatments were considered: 5 and 15 min soaking, 20 min and control (No soaking). With regards to cold water experiment, the following treatments were also considered 12, 24, 48 and 72 h soaking in water. While, under dilute H<SUB>2</SUB>S04, the seeds were soaked for 5, 15, 20 min and control (no soaking). Lastly, seeds were stored in refrigerator for 48, 120 and 192 h and control (no soaking). The results indicated that dilute H2S04 pretreatment of the seeds for 20 min gave a significantly higher percent germination of 90 than other treatment (p< 0.05), while highest germination of 60% was recorded for seeds soaked in cold water for 48 h. Seeds stored in refrigerator had no significant effect on germination as it gave highest germination of 40% after storing for 192 h. However, no germination was recorded for seeds pretreated with warm water. It is recommended that local farmers should adopt these techniques for a better germination of the species.
