Effect of crude oil and simulated acid rain on the growth and physiology of Thaumatococcus daniellii
Abstract
This research work was carried out to investigate the effect of crude oil and simulated acid rain (SAR) on the growth and physiology of Thaumatococcus daniellii. 24 seedlings were planted on soil with different concentrations of crude oil 0.5ml, 2.5ml, 5.0ml, 7.5ml, 10ml, 12.5ml, 15ml and 17.5ml, while soil without crude oil served as the control (0ml). On the other hand, simulated acid rain (SAR) was prepared in varying pH values 4.0, 4.2, 4.4, 4.6, 4.8, 5.0, 5.2, and 5.4 while pH 7.0 served as the control. Results showed that there were no significant differences (p>0.05) in the morphological and physiological traits of plants treated with crude oil at all concentrations except in the percentage dry matter content which showed significance at p<0.05. Plants treated with simulated acid rain (SAR) showed significant differences (p<0.001) in petiole length, plant height, SO4-accumulation, Al3+, H+ accumulation and percentage dry matter content. Results indicated that Thaumatococcus daniellii can be exploited in phytoremediation. Also, there is an indication that the plant species cannot thrivefavourably on high acidic soil.
