Eucalyptus Gomphocephala: Morphological Characterization and Seed Germination under Influence of Contaminated Soil

To study the impact of soil pollution on plant growth, our work focused on soil polluted by heavy metals. This soil was taken from the municipal landfill of Jendouba (North of Tunisia). We have undertaken to study the morphological behavior of a forest specie “Eucalyptus gomphocephala”. Two treatments are chosen (substrate containing 100% and 50% of soil taken from municipal solid waste of Jendouba) compared to a control (pilot soil). Morphological Parameters (stem height, root length, leaf area, the ratio of the stem/root and biomass) was measured. The plants grown on substrates based on an S1 (100% soil taken from municipal waste) and S2 (50%), exhibit morphological appreciable contribution to the control soil.
