Effects of Heavy Crude Oil on the Physiological Responses of Zea mays L. Species

The remediation of oil contaminated soils has been a major problem in oil producing countries. Germination of seeds in soil polluted
with crude oil may be significantly reduced the seeds germination. Apparently, the hydrocarbon film created on the seed surface prevents
the imbibition of water and oxygen to the developing embryo, inhibited seed germination in oil contaminated soil also can be directly
or indirectly related to the presence of oil in soil. The effected of type of crude oil (heavy) was used on different concentrations (0.0 V/V,
0.5 V/V, 1.0 V/V, 2.0 V/V, 4.0 V/V, 6.0 V/V, 8.0 V/V, 10.0 V/V) examined for seed germination and seedling performance the Zea mays
L. (Corn), showed promoted heavy crude oil of Zea mays performance was not affected by heavy oil applications. This might be due to
that heavy oil is more viscous and less soluble in water.
