To examine the impact of microorganisms (PGPR-Planth Growth Promoting Rhizobacteria) on seed germination of field dodder (Cuscuta campestris Yunck.) and alfalfa (Medicago sativa L.) is the most common hosts of this parasite plants were used for bacterial culture: Bacillus licheniformis, B. pumilus, B. amyloliquefaciens, B. megaterium and A. chroococcum Ps 1 were isolated from the rhizosphere of different plants grown and stored in fridge at a temperature of 4 deg C until use. Seeds collected field dodder in the area of Šabac (Serbia) during autumn of 2008. Every day for a period of nine days is done counting germination seeds. All treatments were done in four repetitions, and the whole experiment was repeated twice. Based on the results and statistical data processing, in general it can be concluded that all tested treatments (MO1 - B. licheniformis, MO2 - B. pumilus, MO3 - B. amyloliquefaciens, MO4 - B. megaterium and MO5 - A. chroococcum Ps 1) were similar effect on the germination seed of field dodder and alfalfa. Treatments of bacterial culture of Bacillus demonstrated different inhibitory effect on seed germination, field dodder while the same treatment of bacterial culture of Bacillus are more or less 100% inhibitory alfalfa seed germination. In contrast, the bacterial cultures with A. chroococcum has acted in stimulating germination field dodder and alfalfa.
