Researching regularities of influence of oil on the initial growth parameters of test-objects plants was carried out. It was established the oil, in majority, suppresses viability and growth of plants, but detected those to which oil has a stimulating effect at certain concentrations. The most sensitive to oil pollution are L. usitatissimum, H annuus, F. vulgare. Test-parameters of these plants monotonously decrease with increasing concentration of oil in the soil. The dependence between concentration of oil in the soil and initial growth parameters of plants are close to the linear. Established dependences can be used for biotesting and bioindication of oil-contaminated soils.
