Abstract

Plant bioassays are excellent tools for the evaluation of environmental risks. In particular the use of seeds of vascular plants is recommended due to their higher sensitivity. The aim of this study was to evaluate the behavior of native plants in order for them to be used as biological indicators of environmental oil pollution in relation to a standardized bioindicator. We analyzed the germination index (GI) of Lactuca sativa L., Atriplex lampa (Moq.) D.Dietri. and Prosopis denudans in thirty soil samples taken from an oil field to detect phytotoxic effects. GI, is a cheap, fast and reproducible biological method for determining the toxicity of the soil, thus helping to characterize areas with contaminated soils. The results show that, after germination, Atriplex lampa (Moq.) D.Dietri. and Prosopis denudans are more resistant in the contaminated soils of an oil field than the reference bioindicator (Lactuca sativa L.).
