Laboratory bioassays were conducted to investigate the allelopathic effects of leaf aqueous extracts of Lantana camara on selected tree species (Albizia lebbeck and Dalbergia sissoo). Lantana leaf extracts has significant impact on seed germination on various forest tree species. The effect of different concentrations of lantana leaf extracts (10, 20, 30 and 40%) were recorded and compared with control (Distilled water). The aqueous extracts of Lantana camara causes inhibitory effect on seed germination; shoot length, root length, fresh weight of shoot and root, and vigour index of both the tree species on increasing the concentration of Lantana camara. The leaf extracts have more inhibitory effect on the germination percentage of Dalbergia sissoo than Albizia lebbeck. Results depicted that significant (P<0.05) difference in concentration levels and their interaction for the aforementioned parameters. From this study it is found that Lantana causes inhibitory effect over the germination and growth of these tree species which may be possibly due to allelopathic chemicals present in it.
