Abstract: The allelopathy research can contribute to protecting the biodiversity and may develop new strategies for sustainable ecosystems controlled by allelochemicals. The present investigations have estimated the allelopahtic features at Festuca rubra and the ability of the allelopathic compounds to affect the germination and the quality of perennial grasses (Dactyilis glomerata, Lolium perenne and Poa pratensis). These perennial grasses were treated with alcolic extracts obtained from dry aerial parts of Festuca Rubra. Were quantified and also physico-chemical characterized the polyphenolic compounds and the alkaloids from the chemical structure of plants. The extracted compounds from the dry aerialparts of F. Rubra were quantified using HPLC method. In the aqueous extracts were quantified the following alkaloids: N-formyl-loline (NFL), N-acetyl-loline (NAL) and ergovaline (EGV). The results of the research have showed that the effect of the alkaloids lead to modifications in the quality index by reducing of the crude protein content and thus lead to lower feed value of these plants.
