ABSTRACT
In order to know the
capacity of Desmodium ramosissimum species to grow and replenish in a crude oil
polluted soil, an experiment was carried out. Two weeks after planting, number
of leaves, plant height, stem girth and leaf area were evaluated bi-weekly. Heavy
metals (Copper, Nickel, Lead, and Cadmium) concentrations of crude oil
contaminated soils were determined for 16 weeks after planting. Also
phytochemical constituents of the plant and changes in anatomy in the
vegetative parts of the plant were examined. The mean values of the growth
parameter obtained were higher in control soil (0%) and then progressively
decreased in 1 4% crude oil polluted soil. The crude oil pollution had a
significant (P0.05) effect on leaf area, number of leaf, plant height and stem
girth, but significant (P~0.0T) only on leaf area and plant height. •The plant
accumulated heavy metals in their vegetative parts. Lead accumulated more in
the root and leaves followed by Copper, Nickel and Cadmium, while higher amount
of'copper (48 mg/100 g) and Nickel (26.2 mg/TOO g) were left in the soil 16
weeks after planting. Those plants in polluted soils (1 - 4%) exhibited greater
sinuosity in their epidermal cell walls compared to those in controls (0 %).
Also seen were oil droplets in the ground tissues of the contaminated plants.
The presence of phytochemicals like alkaloids, flavonoids, saponins and tannins
mostly observed on the leaves and the u.ptke ofthe heavy metals by the
vegetative parts of I). ramosissinnim and their changes in anatomy in response
to oil pollution were discussed in the light of their possible economic value
and use in phytoremediation and phytoindication of crude oil polluted soils.
