The experiment was conducted at the Toxicology laboratory, Faculty of Agriculture, Universiti Putra Malaysia, Serdang, Malaysia in 2013. Allelopathic potential of aqueous methanol and water extracts of M. cochinchinensis leaves, seed and root was investigated on seed germination and seedling growth of goosegrass and biotest crop species: lettuce (Lactuca sativa). The treatments consisted of five concentrations (100, 75, 50, 25, 0 %); plant parts (leaves, seed, root) and extraction solvents (methanol, water) were replicated three times and arranged as a completely randomized block (CRD) design. Germination, radicle and hypocotyl growth of all test plant species were inhibited at concentrations (100, 75, 50 and 25%). The total germination percentage was lowest with the methanolic extracts of leaf, seed and root of M. cochinchinensis at 100 % concentration in the order of 0.00, 30.66 and 4.66%, respectively. Concomitantly, the radicle length inhibition percentages of methanolic extracts at higher concentration of 100% were 100, 88.5 and 94.4% of the leaf, seed and root extracts, respectively. The water extracts recorded the highest germination percentage and lower inhibitory activity of the radicle and hypocotyl length. The study confirmed plant growth-inhibitory compounds of M. cochinchinensis is dependent on the extraction solvents and extract concentrations as expressed that methanolic solvent at higher extract concentration had the stronger inhibitory activity.
