Abstract
Arundo donax often dominates plant communities by forming large stands throughout Mediterranean climate zones. The objective of this study was the investigation of allelopathic property of A. donax leaves on germination and seedling growth of lentil (Lens culinaris) under laboratory and greenhouse conditions. Four concentrations of aqueous extract (2, 4, 6, and 10%) were compared with the control (distilled water). The germination percentage of lentil seeds was significantly reduced at extract concentrations ≥ 6%. Aqueous extracts of A. donax at concentrations of 6 and 10% significantly reduced the germination percentage of lentil with reduction percentages of 21.3% and 47.4%, respectively. Aqueous extract of A. donax significantly delays the germination process of lentil and reduces the seedling vigor index. Root and shoot growth of lentil seedlings were significantly inhibited by the extract. Root growth was more suppressed than shoot growth in response to A. donax aqueous extract. The results suggested that A. donax aqueous extracts possesses allelopathic potential which could explain in part the dominance competitiveness for this invasive species. Further, the A. donax extract or its active substances could be used for the development of bio-herbicides as alternatives of commercial herbicides.
