Abstract:
Allelophathic potential of aqueous extracts of leaves of Prosopis juliflora and Eucalyptus camaldulensis and bark of Acacia nilotica @ 0, 150, 100 and 59gL"`.The dry plant materials were ground and soaked for 24 hours in water. Ten seeds each of Triticurn aestivum; Avena fauna and Carthamus oxycantha were used as test species. The data were recorded on germination percentage, seeding length (mm) and biomass (mg) plant. There were two identical runs of the experiment. The inhibition was recorded in all the species for all the parameters studied, but it was most pronounced in the ation percentage. Carthamus oxycantha was the most inhibited . Wheat was the most tolerant. Only 20% seeds as compared to the check germinated . in this species when exposed to E. ulensis @ 150 gL-`.AII other concentrations of P. juliflora and E. ensis proved severely inhibitory to germination of C.oxycantha.For parameters the inhibition was observed at the higher concentrations of and E.camaldulensis. Acacia nilotica emerged as the weakest in inhibiting the growth parameters of the tested species.
