“…Some research results showed that crude oil has harmful effects on plant seed germination [2,3]. On the contrary, other studies found that low oil concentration can improve the seed germination and accelerate the seeding growth [4,5]. Therefore, further study should be done in order to clarify the effects of oil pollution on plant growth.…”

The effects of oil-contaminated soil on plant growth are the focus study area all over the world. In this paper, two kinds of local plant seeds germination and seedlings growth in oil-contaminated soil were studied by germination experiment. Five different oil concentration gradients (0g/kg, 0.2g/kg, 5g/kg, 20g/kg, 40g/kg) were set up in this experiment, and the seed germination rates and bud length of wheat and rice cultivated in thermostat were observed and recorded. The results showed that crude oil took negative effects on wheat seed germination and germinability. With the oil concentration increasing, the germination rate of wheat seed and germinability decreased respectively. Crude oil impacted the seeding growth obviously, even under low oil concentration (20g/kg). Seedling growth almost stopped under high oil concentration such as 40 g/kg. Crude oil promoted germination and germinability of rice seed. The germination rates and germinabilities of three Oil concentrations (0.2 g/kg, 5 g/kg, 20 g/kg, 40 g/kg) were all higher than that in pure soil, further, the higher the oil concentration was, the germination rates and germinabilities were higher. Oil also accelerated the rice seedling growth under three different concentrations.
