THE EFFICIENCY OF BARLEY HORDEUM VULGARE IN PHYTOREMEDIATION OF CRUDE OIL - CONTAMINATED SOILNAYYEF M. AZEEZ AND DHURGHAM A. QASIMAbstract This study aimed to evaluate the phytoremediation potentiality of barley Hordeum vulgare L. that could be used to remediate hydrocarbon from the contaminated soils. A pot culture experiment was conducted taking 2 kg of field soil mixed with crude oil at a concentration of 25, 50, 75, and 100g.kg-1. Ten healthy seeds of barley were sown in pots of each concentration for germination. A control setup was maintained without adding crude oil. The duration of the experiment was fixed for three months. The results showed that the plantsâ uptake of hydrocarbon increased with increasing crude oil concentration in the soil. The results also demonstrated a reduction in plant shoot and root biomass with an increase in crude oil concentration. Furthermore, the results revealed that the shoot biomass was higher than root biomass in all the treatments. BCF of barley was the highest in low concentration treatment. |
