Studies On Anatomy Of Digitaria Horizontalis H. And Setaria Barbata L. As A Phytoremediator Of Waste Engine Oil Contaminated Soil:- Chukwu, Martin K.
ABSTRACTS
Waste engine oil (WEO)
contaminated soil has been considered as harmful to the soil and plants
physiology as well. The study was carried out to evaluate the effect of waste
engine oil contaminated soil on the anatomy of Setaria barbata and Digitaria
horizontalis and the concentrations were 0%, 2%, 4%,7% and 10% respectively.
The experimental grasses (D. horizontalis and S. barbata) were collected from the
wild fallow farmland in the university campus and the waste engine oil obtained
as pooled used engine oil from heavy-duty vehicle at motor mechanic workshop in
Umuahia, Ahia state. The soil used in this research were sieved and homogenized
with the waste engine oil. The plants were raised in buckets containing 4kg of
sieved sand each at 80ml, 160ml, 280ml and 400ml. The waste engine oil was
mixed to the 4kg sand in the buckets. Each treatment including the control was
replicated three times (3x). The plants were allowed for six weeks. At the
control, the stomata of S. barbata and D. horizontalis were clearly viewed but
as the concentration increased reduction in stomata and increase in sinous
epidennal cell wall were seen. Large parenchyma and intercelJular air spaces
was observed in the stem then the root experienced distortion in the parenchyma
pith on both plants (D. horizontalis and S. barbata). This showed that at high
concentration of waste engine oil contamination, the anatomic structure and
arrangement of celJs and tissues are affected negatively and the ability for
the two experimental plants (D. horizontalis and S. barbata) to withstand this
stress made them fit for phytoremediation.
