dc.description.abstractThe ability of different bacteria to inhibit Orobanche radical elongation was examined. Seeds of Orobanche aegyptiaca Pers. and O. cernua Loefl. were induced to germinate with the Growth Regulator GR24 in the presence or absence of test bacterium. Radical lengths were estimated microscopically on a scale relative to seed length (0 5 seed lengths) after 5 days of incubation at 258C. The results indicated that Pseudomonas aeruginosa QUBC1, P. fluorescens QUBC3, Bacillus atrophaeus QUBC16, and B. subtilis QUBC18 significantly inhibited radical elongation (P50.01) of both O. aegyptiaca and O. cernua relative to control radicals, whereas Microbacterium hydrocarbonoxydans QUBC11 and Ochrobactrum anthropi QUBC13 showed less inhibitory effects. Other bacterial isolates had no inhibitory effects. Bacterial isolates were identified using the universal method in addition to morphological and biochemical features. The establishment of the inhibitory effect of the most promising isolates, B. atrophaeus QUBC16 and P. aeruginosa QUBC1 on radical elongation of both Orobanche spp. is a step towards utilizing such bacteria as biocontrol agents against O. aegyptiaca, O. cernua, and potentially other Orobanche species.en_US
