The effects of environmental pollutants on plants can be monitored using various techniques at different levels. Random amplified polymorphic DNA RAPD is a semi-quantitative technique that has been used for genetic mapping, taxonomy, phylogeny and the detection of various kinds of DNA damage and mutations that result from genotoxic agents such as heavy metal contamination. In this study, tomato Lycopersicum esculentum L. seeds that had germinated in various concentrations of Pb NO3 2 solutions were used for measuring population parameters such as dry weight, total soluble protein content, root length and, ultimately, inhibitory rate IR values. The seeds were also used to determine the genotoxic effect of the lead, reflected as the appearance or disappearance of bands in RAPD profiles. Inhibition or activation of root elongation was found to be the first effect of metal toxicity to show up in the plants that were tested. Also, total soluble protein content was significantly affected by increased Pb2+ concentrations. The data obtained from RAPD band profiles and genomic template stability GTS revealed results that were consistent with the population parameters}, number={1}
