ABSTRACT

Water leachates of aerial parts of Acacia dealbata Link were artificially obtained during one complete year, beginning during flowering, and bioassayed to explore their allelopathic potential on germination and growth of Lactuca sativa L. Var. Great Lakes. Results indicate that the potential phytotoxicity is related only to blooming phase, independently of other factors that could also influence this allelopathic effect. A short methodological discussion about the validity of obtained results is done.


Keywords: Acacia dealbata, Allelopathy, Germination Bioassays, Lactuca sativa var. Great Lakes, water leachates.
