Abstract: We evaluated the allelopathic effects of leaf leachates, aqueous and organic extracts from Tetraclinis articulata on seed germination and seedling growth of lettuce, barley, radish and tomato. Leaf powder from T. articulata added to soil and leaf leachate irrigated soil were evaluated in pot assays. The leaf extracts and the leachate significantly decreased the germination of the target plants. Total inhibition of lettuce, tomato and radish seedling growth was observed at 40g/l and 500g/l concentrations for the extract and the leaf leachate, respectively. All organic extracts were very toxic at 6000 ppm. Soil incorporation of residues at 100 g/kg significantly decreased the root and shoot length of target species. The irrigation with leaf aqueous extracts was harmful for tomato, radish and lettuce and leachate was harmful only to lettuce and tomato. Quantitative and qualitative analyses of the extracts were done by gas chromatography-mass spectrometry to identify the allelochemicals present in leaves
