摘　　要：Current study aims to investigate the allelopathic potential of the differentparts (leaf, bark, stem, twig and root) of three oil-enrich plant species ofBangladesh viz., Jatropha curcus, Ricinus communis and Aphanamixispolystachya. The aqueous extract of those plant parts were diluted intofour different concentrations viz., 1:5, 1:10, 1:15, 1:20 (w/v) and testedagainst the seedling growth of jute, rice, wheat, radish, tomato, mungbeanand mustard under control laboratory condition. A control (distilled waterwithout extract) was also maintained in every cases and the bioassayexperiment was replicated thrice. The results of this research showed thatthe shoot and root growth inhibition of rice, wheat, jute, tomato, radish,mungbean and mustard by leaf, bark, stem, twig and root extracts of J.curcus, R. communis and A. polystachya varied significantly. Compareto the shoot growth, the root growth of the test species inhibited moreexcept J. curcus. The leaf and root have higher allelopathic potential thanany other parts of the studied plants. Finally, it can be concluded here thatJ. curcus plant extracts has higher allelopathic potential than other twoplants R. communis and A. polystachya. Therefore, J. curcus can be usedas a candidate plant for isolation and identification of allelopathic substancesfor the development of new natural herbicides.
