Abstract
Sunflower plants were grown in the laboratory under continuous light on the ground, the sand and the liquid medium. Fluorescence parameters were measured using PAM fluorimeter (Walz, Germany) and optical spectrophotometric sensor CCM-200 plus, Opti-Sciences, USA). The change of parameters of Fo, Fm, Fv/Fm, ETR and CCI in leaves after addition of oil at a concentration of 6 g/kg is investigated. It is shown that the parameters CCI and ETR (electron transport rates) are most sensitive to oil pollution. The value of the CCI in sunflower leaves increased (compared to control) after the addition of oil in the soil and decreased after the addition of oil in sand and liquid culture medium.
