| summary |
Laboratory experiments were conducted to screen the allelopathic activity of the leaf litter leachate and leaf volatilization of ten different tree species by using sandwich and dish pack method, respectively. The leaves from ten tree species that were collected from Besut District of Terengganu were used as plant materials of donor plants. The site of the study was composed of BRIS (Beach Ridges Interspersed with Swales) soil. Lactuca sativa (lettuce) were used as the receptor plants for both methods. In sandwich method, the lettuce seedlings growths were tested using different amounts of leaf litter (5 mg, 10 mg and 50 mg) in agar media. Whilst, in dish pack method, the lettuce seedlings growth were evaluated through the different distances of the leaves from donor plants towards the lettuce seedlings (41 mm, 58 mm, 82 mm and 92 mm). The results from sandwich method showed that the highest radicle inhibition was by Tamarindus indica (81%) followed by Terminalia catappa (57.22%) and Leucaena leucocephala (54.13%); whereas, the highest hypocotyl inhibition was by Tamarindus indica (63.70%), followed by Leucaena leucocephala (27.75%) and Melaleuca cajuputi (27.08%).
