Tomato plants (Solanum lycopersicum L.) grown in experimental contaminated soil: Bioconcentration of potentially toxic elements and free radical scavenging evaluation.

摘要: Tomato is the most widespread vegetable crop in world. In Italy, tomatoes are mainly cultivated South and Campania region, precisely area called Agro Nocerino-Sarnese. This flatland affected by an extreme level of environmental degradation, especially related to Sarno River, where concentrations Potential Toxic Elements (PTEs) have been found be higher than maximum permitted level. The aim this study was determine PTEs uptake roots their translocation aerial parts plants two cultivars (Pomodoro Giallo San Marzano Cirio 3). To purpose, samples were grown both pots with experimentally contaminated soil containing: Cr or Cd Pb at extremely high uncontaminated soils (control). Additionally, antioxidant properties selected on uncontaminated/contaminated assessed. results showed that contaminant significantly interfered growth tomato plants, whereas caused lower phenotypical damage. from root organs observed cultivars. Specifically, total amount stems leaves Pomodoro (254.4 mg/kg dry weight) 3 (165.8 weight). only PTE fruits cultivars, values 6.1 3.9 weight 3, respectively. PTEs-contaminated inhibition stimulations radical scavenging activity compared soil. highlighted that, despite relatively experimental PTEs, edible part comparatively low absent.
