The present revision was aimed to assess the germination and growing responses of green gram seeds which were exposed to various (control, 1%, 5%, 10%, and 20%) concentrations of dried leaves of Tecomastans (L.) by conducting laboratory tests. Dried leaves of Tecomastans (L.) affected negatively the radical length, reduced germination percentage, delayed germination and hindered shedding of seed coat in green gram. Bioassay readings showed that the total protein activity, amylase activity, invertase activity and protease activity were significantly reduced with increasing concentrations of the Tecomastans (L.) leaf extracts. The maximumaction of all the biochemical components of the green gram was found in control while as minimum action was found in 100% of extract concentration. The tolerance index was found to be reduced while as the phytotoxic index was found to be improved from control to 100% in day by day of the experiment. The germination index was found to be increased on a daily basis of the experiment. The possible biochemical feature responsible for such allelopathy is debated grounded on earlier reports.
