Studies were made on some aspects of the seed germination and seedling growth of two multipurpose trees. These include the effect of pre-sowing treatments, seed sizes and gibberellic acid on the germination of seeds and seedling growth. The tree species include Prosopis africana (Guill. & Perr.) Taub. and Dialium guineense (Wild). Two seed sizes designated small- size (Ss) and Big-size (Bs) were identified in the seed. The effect of gibberellic acid (GA3) had a greater significance effect (P < 0.05) on seed germination of both D. guineense and P. africana seeds. The big size seeds had a significant effect (P < 0.05) on the seed germination when compared to the small size seeds. The hydration/dehydration, pre-sowing treatments on the seeds did not have any significant effects on germination.
