Evaluation of the early growth performance Bauhinia monandra, Delonix regia and Tetrapleura tetraptera (Leguminous Tree Species) in crude oil-contaminated soil.

This study investigates the early growth performance of Bauhinia monandra, Delonix regia and Tetrapleura tetraptera (Leguminous Tree Species) (LTS) on crude oil-contaminated soil. It aimed to assess the growth performance of these LTS species in different levels of crude oil contamination (0, 25, 50, 75 and 100 ml in 4000 g soil; which represents the degree of light crude oil spillage concentration of 0.0, 0.63, 1.25, 1.88 and 2.5 %v/w respectively) on the growth performance. Seedling height, seedling girth and number of leaves were measured following standard protocols. The effectiveness of the 3 LTS for phytoremediation were in the order; D. regia > B. monandra > T. tetraptera. Results revealed percentage germination, seedling height, seedling girth and number of leaves decreased as the concentrations of crude oil in the soil samples increased at P<0.05. The tendency of the LTS plants under study suggests that they are promising for crude oil remediation in soil.
