Abstract :The present study was conducted to examine the effects of bio-priming with plant growth promoting rhizobacteria insert ignore into journalissuearticles values(PGPR); on the germination of radish insert ignore into journalissuearticles values(Raphanus sativus L.); seeds under different saline insert ignore into journalissuearticles values(NaCl); conditions. Three radish cultivars insert ignore into journalissuearticles values(`Antep`, `Beyaz`, and `Siyah`); were used as plant material and 5 bacteria strains insert ignore into journalissuearticles values(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.
