Abstract:
The allelopathic potential of Eucalyptus tereticornis Sm. an introduced species was assayed by using aqueous extracts from leaves, flower-buds and bark against Sorghum vulgare vairable Sorghum vulagare var. Wiay, Phaseolus mango, Brassica chinensis, B. campestris, Sisymbrium firo, Nigella sativa, Raphanus sativus and Setaria italica in filter paper bioassays. The germination and radicle growth of various species was reduced by aqueous extracts, especially by leaf and flower bud extracts, Sisymbrium, Nigella and Brassica were more susceptible than other species. The phytotoxicity depended upon the part assayed, and test species used with an independent effect on germination of growth. Aqueous extracts through soaking is one of the suggested routes for releasing phytoxins in this plant. Further study is underway to envisage other aspects of allelopathy by this eucalypt.
