The phytotoxic effects of gasoline on Ischaemum rugosum were investigated in 2005 in Benin-City, Edo State, Nigeria. 0, 2, 4 and 8 L m-2 of gasoline served as the treatments. The experiment was arranged in a Randomized Complete Block Design (RCBD) and replicated four times. The results showed a significant decrease (p≥0.05) in plant height, number of leaves, leaf area, shoot and root biomass and percentage mortality with increasing concentration of gasoline in soil when compared with I. rugosum plants grown in soils without gasoline treatment (control). At 9 Weeks After Transplanting (9 WAT), I. rugosum plants at 2 and 4 L m-2 gasoline treatment showed generation potential compared to those in 8 L m-2, which showed no regeneration capacity even at 12 WAT. The study has established that soils contaminated with gasoline have a highly significant effect of reducing the growth characters of Ischaemum rugosum. The study has also demonstrated that I. rugosum could regenerate at low concentration of gasoline contamination. |
