Striga seeds required after- ripening, pretreatment (conditioning) in moist warm environment for 2-14 days and subsequently exposure to an exogenous stimulant. In the present study, an inhibitor of ethylene biosynthesis, AgNO 3 and CoCl 2, was found to inhibit germination. Germination was found to be inhibited by higher concentrations of AgNO 3 and CoCl 2. Combination of ACC with AgNO 3 and CoCl 2 increased Striga seeds suppression as compared with control. Also this study investigates the effect of microorganism in Striga germination. Klebsiella spp. strains known to produce large amounts of ethylene w ere tested for efficacy in germinating seeds of Striga hermonthica (Del.) Benth. Incubation of conditioned S. hermonthica seeds over a medium inoculated with a Klebsiella sp. resulted in considerable germination (34-49%) this indicates an involvement of a volatile substance. Unconditioned S. hermonthica seeds were not stimulated. | Cite this Reference: M.M. Hassan, M.E. Abdelgani, A.E. Babiker and M.G. Osman, 2010.
