Abstract

In the era of increasing environmental pollution, microevolutionary processes occurring in plants inhabiting anthropogenic areas play a special role. With time, these processes may lead to formation of new plant species. A good example of occurrence of microevolutionary processes on anthropogenically altered areas is the metallophyte Biscutella laevigata L. The studies have shown the existence of significant morphological, anatomical and physiological differences between two groups of the B. laevigata populations occurring in Poland – the population of calamine waste heaps in Bolesław near Olkusz (Silesian Upland) and the population inhabiting the Tatra Mountains (Western Carpathians). The demonstrated differences are the adaptation (hereditary characteristics) of the plants to the unfavorable conditions of the calamine waste heap, i. a. high concentration of heavy metals in the soil. The research has also shown theexistence of significant differences between these two groups of populations – both at the genetic and morphological levels (a clonal form of vegetative propagation, removal of heavy metals by the oldest and drying leaves, a zinc tolerant species, trichomes accumulating metals, metal detoxification at the cellular level). The demonstrated differences between the zinc-lead (calamine) waste heap population and the Tatra Mountains population indicate the existence of the new subspecies of Biscutella laevigata subsp. woycickii on the heaps in Boleslaw, in Poland.
