E Department of Forestry and Wildlife, Faculty of Agriculture Delta State University, Asaba Campus, Delta State,Nigeria Okechukwu, E. M Department of Forestry and Wildlife, Faculty of Agriculture Delta State University, Asaba Campus, Delta State,Nigeria Abstract A study was carried out in 2005 on the seedling growth of Gmelina arborea as influenced by crude oil in soil in Asaba, Delta State, Nigeria. The experiment was laid out in a randomized complete block design with four treatments (0% (control), 4%, 8% and 12% wet weight (w/w) of crude oil) and replicated four times. Parameters measured at different growth stages (1, 2 and 3 months after transplanting) were plant height, number of leaves, leaf area, collar girth and dry weight biomass per seedling per treatment. The results showed significant reductions (P=0.0.5) in all the growth characters assessed throughout the experimental period in seedlings subjected to crude oil treatment when compared with those grown in the uncontaminated soils. The height, number of leaves, leaf area and collar girth of seedlings exposed to 12% oil treatment was 29. 6 cm, 6.3, 50.2 cm 2 and 1.0 cm while those in the control soils were 49.4 cm, 17.8, 109.3 cm 2 and 2.2 cm at 2 months after transplanting respectively. This study has demonstrated that crude oil contaminated soil significantly reduced the performance of Gmelina seedlings. The present study indicated that G. arborea could be tested for phyto – remediation studies in crude oil contaminated areas. Key words: Crude oil, soil contamination, seedling growth, Gmelina arborea. Introduction Gmelina, Gmelina arborea, a fast growing exotic tree species was first introduced to Nigeria in 1924 (Akoun et al., 2002). It is a fuel wood and a chew stick species. Goat and sheep relish G.arborea greatly (Etukudo, 2000). With the current high cost of building materials, many people are using wattles as support in wattle – and - daub houses and G. arborea is a popular species in this direction. In the rain forest and derived savanna zones, G. arborea is recommended for use in our farms to supply nitrogen to the soil (Etukudo, 2000). He maintained that G. arborea is among the trees recommended
