Abstract
This experiment was carried out in the autumn of 2000 in laboratory condition. The aim of this work was to estimate allelopathic potential of Hieracium pilosella on early development of turf grass grains (Lolium perenne, Festuca rubra). The effect varies concentration of Hieracium pilosella plant and rhizosphere soil extracts on energy and capacity of germination and on the seedling length of grasses was evaluated. The obtained results showed that the energy and capacity of germination for both grasses decreased proportionally to increasing concentration of extracts used, whereas the rhizosphere soil extracts influenced positively seedling length of Lolium perenne.
