Abstract

Phytoremediation is an emerging technology where plants are used for environmental cleanup. Crude oil contaminated soils are one of the most challenging tasks for phytoremediation applications due to the complexity of the process affected by variability in chemical composition of oil, plant-microorganism interactions and phytotoxicity of contaminants. Although signs of phytotoxicity are very often easily visible, sometimes plant physiological processes can indicate stress in plants due to the presence of xenobiotics in cases without visible signs. This paper presents investigation of the potential of various poplar (Populus sp.) clones for phytoremediation of soils contaminated with crude oil through assessment of physiological parameters. Biomass production together with: (i) nitrate reductase activity; (ii) net photosynthesis/dark respiration, (iii) proline content (iv) chlorophyll fluorescence and (v) pigments contents were studied. Investiagted clones showed various reactions to the different levels of soil contamination.
