الملخص

One of the major environmental problems is the contamination of the atmosphere,water and soil by many toxic elements and compounds such as lead, which is a harmfulelement and has no biological advantage.This requires the use of an alternative technique for the decontamination ofcontaminated soils, called "Phytoremediation", which consists of using plants and/ormicro-organisms to decontaminate these soils.Plants are more sensitive to the germination stage because it is the first phase ofplant development and this is a critical step in the evolution of plants in a leadcontaminatedenvironment.The purpose of this work is to determine the impact of increasing concentrations ofPb (0, 3, 5, 7, 7 and 10mM) on the kinetics of the germination rate and the elongation ofthe roots and tigelles of Moringa oleifera L. The seeds were put to germinate in Petridishes, at a rate of 10 seeds per dish and five repetitions for each treatment, which are thenplaced in the dark in an oven, at a temperature of 27°c, for fifteen days. The number ofsprouted seeds and lengths of roots and tigels were collected daily every other day.The results obtained show that lead has a negative effect on the germination ofMoringa oleifera L. seeds, which results in a decrease in the germination rate of leadtreatedseeds compared to the control where a germination rate of 100% was recorded inthe absence of Pb, as well as a significant decrease in the elongation of Moringa oleifera L.roots and tigelles, at the level of seeds treated with high lead concentrations (7 and 10mM).
