초록

Aqueous and dichloromethane (DCM) extracts of leaves, root bark and inflorescences of Parthenium hysterophorus L. at various concentrations were used to quantify its allelopathic potential against Indigofera tinctoria, Amaranthus viridis, A. gangeticus, Phaseolus mungo (cv. CO 1), Sorghum vulgare (cv. SPT- 462). Pennisetum typhoideus (cv. WCC-75) and Eleusine corocana (cv. CO 1). The aqueous extracts were more inhibitory than the DCM extracts to the germination and seedling growth of the plants studied. The relative rate of inhibition increased in the order of inflorescences. leaves and root bark in the aqueous extracts. whereas DCM root bark and inflorescences extracts were promoted at lower concentrations.
