摘要: Petroleum contamination and its remediation via plant-based solutions have got increasing attention by environmental scientists engineers. In the current study, physiological growth responses of two diesel-tolerant plant species (tolerance limit: 1500–2000 mg/kg), Italian ryegrass (Lolium multiflorum) Birdsfoot trefoil (Lotus corniculatus), been investigated in vegetable oil– diesel oil–amended soils. A long-term (147-day) greenhouse pot experiment was conducted to differentiate main focus study: physical chemical effects oil (vegetable diesel) freshly spiked soils evaluating performance hydrocarbon degradation. Moreover, evaluated terms seed germination, shoot biomass, parameters, root biomass. Addition both showed deleterious on seedling emergence, root/shoot chlorophyll content grass legume plants. more sensitivity germination rate as compared non-contaminated while reduced only oil–impacted The results study suggest that pose negative development. This observation may explain phenomenon aged/weathered contaminated during rhizoremediation experiments.
