The soil petroleum pollution impact on the lettuce seed germination

The increase in biomass indicators, root length, as well as sprout length, of 4-day germs with petroleum concentration of 3 and 6 of g/kg in the soil that is probably caused by the plant additional nitric nutrition is determined in the laboratory experiments. The petroleum negative effect on the seed germination with the pollutant concentration of 9 g/kg and higher, that is apparently connected with hydrophobic film formation on seeds and roots, worsening their gas and water exchange is registered.
