TY - JOUR N2 - The aim of the paper is to improve the phytoremediation features of the metallophyte Silene vulgaris through photo-stimulation of seeds using a semi-conductive laser. Seeds of two Silene vulgaris ecotypes were used in the experiment. One type of seeds – “Wiry” ecotype – originated from a site contaminated with heavy metals (a serpentinite waste heap), and the other ecotype – “Gajków” – was collected on a site with naturally low heavy metal content. The seeds of both types were preconditioned with laser light with previously fixed doses: C(D0), D1, D3, D5, D7, D9. The basic radiation dose was 2.5·10-1 J·cm-2. The soil for the experiment was serpentinite weathering waste. The seeds and plants were cultivated in the controlled conditions of a climatic chamber. Laser light indeed stimulated seed germinative capacity but better effects were obtained in “Wiry” ecotype, originating from a location contaminated with heavy metals. In the case of morphological features, a significant differentiation of stem length was found for different ecotypes, dosages and the interactions of these factors. The study showed a strong influence of laser radiation on selected element concentrations in above-ground parts of Silene vulgaris, though “Wiry” ecotype clearly accumulated more heavy metals and magnesium than the “Gajków” ecotype.
