Three radish cultivars (‘Antep’, ‘Beyaz’, and ‘Siyah’) were used as plant material and 5 bacteria strains (Agrobacterium rubi strain A 16, Burkholderia gladii strain BA 7, Pseudomonas putida strain BA 8, Bacillus subtilis strain BA 142, and Bacillus megaterium strain M 3) were applied as priming agent. The effect of bio-priming with PGPR on germination percentage under saline conditions varied with bacteria strains and cultivars. Applications of bio-priming with bacteria strains significantly improved the percentage of seed germination under saline conditions. These results suggested that bio-priming with PGPR under saline conditions could be useful to obtain higher seed germination percentages in radish.
