Abstract:
In this study the effect of different concentrations of light crude oil (up to 10%) on the growth and germination of Festuca arundinacea (Tall fescue) was studied. Present results showed that the germination number and dry biomass of the plant decreased by increasing light crude oil concentration in the soil. The biomass was higher in 1% crude oil sample while it was lower in 10% crude oil sample. The length of leaves reduced in higher crude oil concentration in comparison with the control. Total and oil-degrading colony count of soil showed that the microbial population in 7 and 10% samples was higher than the control and low concentrations of crude oil (1 and 3% samples). The crude oil reduction in the vegetated and the non-vegetated samples was higher in 1% sample. All vegetated samples had higher crude oil reduction than non-vegetated samples. The higher reduction was occurred at 1% sample, while the lower reduction was seen at 10% sample.
