Germination and Seedling Growth Bioassay for Evaluation of Allelopathic Potential of Petiferiaalliace aagainst Four Selected Seeds

Adedeji Timothy Adesipo, Labunmi Lajide, Bodunde J Owolabi, Femi Adejoro


The allelopathic potential of Petiferia alliacea was evaluated using seed germination and seedling growth bioassay. Seeds of Amaranthus,Tomato, Cowpea and Maize were used as test seeds and the medium was Whatman No1 Filter paper placed in Petri Dish. Different concentrations of Petiveria alliacea extract in MeOH was prepared and used -1%, 2.5% & 5% w/w. The extract inhibited the seed germination and growth of the Amaranthus and Tomato to a large extent, while seeds of cowpea and maize were inhibited to a reasonable extent. The result showed that Petiveria alliacea has considerable allelopathic potential and can be further studied
