Abstract
The features of growth of C. hirta on the oil-contaminated soil were studied for the first time. Reduction of morphometric parameters of leaves, rhizomes, and enlargement of roots under the influence of oil were determined. Duration of morphogenesis of C. hirta plants on the oil-polluted soil was also reduced. Early ageing of leaves was observed. Rhizomes of the plants from the petropolluted soils branched less. Their plagiotropic growth soon changed to the orthotropic. As the result of the study, the data on morphology, morphogenesis and ecology of C. hirta were replenished.
