Seed germination represents the first crucial stage in the life cycle of a plant, and the seed must contain all necessary transition elements for the development and successful establishment of the seedling. Problematically, seed development and germination are often hampered by elevated metal(loid) concentrations in industrially polluted soils, making their revegetation a challenging task. Biscutella laevigata L. (Brassicaceae) is a rare perennial pseudometallophyte that can tolerate high concentrations of trace metal elements. Yet, the strategies of this and other plant species to ensure reproductive success at metalliferous sites are poorly understood. Here we characterized several parame..View full abstract
