“…Inoculation of A. chroococcum enhanced the plumule length of Chinese cabbage significantly by 1.75 and 2.25 cm under salinity of 50 and 100 mM of NaCl, respectively. Similar results were shown by Kim et al (2012), they found that co-inoculation of Brevibacterium iodinum and Methylobacterium oryzae mitigated the salinity stress and promoted the root length of maize and sorghum seedling by 22.9% and 29.7%, respectively. However, under salinity level of 150 and 200 mM of NaCl, A. chroococcum did not show positive effect on the plumule length.…”

Salinity has been a threat to agriculture in some parts of the world; and recently, the threat has grown. Plant growth-promoting rhizobacteria (PGPR) may benefit plant growth, either by improving plant nutrition or producing plant growth hormones. The effects of rhizobacterial strains to attenuate the salinity stress on the germination of Chinese cabbage seeds were tested using four different concentrations of NaCl (50, 100, 150, and 200 mM). Also, PGPR strains were tested to enhance the early germination of Chinese cabbage seeds under normal conditions. Azotobacter chroococcum performed best with enhancing the radicle length of 4.0, 1.2, and 1.0 times at treatments of 50, 100, and 150 mM of NaCl, respectively. Additionally, significant differences were found in plumule length, A. chroococcum and Lactobacillus sp. showed remarkable activation either in normal or under stress conditions. Co-inoculation by three rhizobacterial strains (LAPmix) indicated synergistic effect to enhance the early germination of the seeds. The results of this study are promising for application of rhizobacterial strains that possess plant growth promoting traits to enhance the plant tolerance against salinity.Key words: Rhizobacteria, Salinity, Tolerance, Plant growth promotionThe effect of different inoculations on the length of radicle and plumule and the seeds germination percentage of Chinese cabbage, Brassica rapa var. glabra, after 96 hour under normal conditions.

“…plant growth. Several earlier studies also documented the single and co-inoculation increased plant height (Kim et al, 2012;Saber et al, 2012). We got the same kind of results with Adesemoye and Kloepper (2009), who reported that plant height significantly higher in bacterial inoculated treatment compared to non-inoculated treatment.…”

The objective of this study was to determine the effect of single and co-inoculation of plant growth promoting bacteria (PGPB) on early plant growth in Saemangeum reclaimed soil. Plant growth promoting Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 were inoculated on maize (Zea mays L.) and sorghum-sudangrass hybrid (Sorghum bicolor L.) grown in Saemangeum reclaimed soil. Single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased plant height, dry biomass accumulation and macro-nutrient accumulation of maize and sorghum-sudangrass hybrid. M. oryzae CBMB20 treatment increased plant height in maize by 41.2% at 30 days after sowing (DAS), shoot dry weight and total dry weight compared to non-inoculated treatment. Macro-nutrient accumulation (N and P) in maize roots was significantly increased with co-inoculation treatment, K and Ca content was significantly increased at B. iodinum RS16 treatment compared to non-inoculated treatment. Macro-nutrient accumulation (P, K, Ca and Mg) in shoot was higher with M. oryzae CBMB20 treatment compared to non-inoculated treatment. In case of sorghum-sudangrass hybrid, co-inoculation treatment showed 33.7% increase in plant height compared to non-inoculated treatment at 30 DAS. M. oryzae CBMB20 treatment increased root dry weight and total dry weight, macro-nutrient accumulation in roots and N, Ca and Mg accumulation in shoot compared to non-inoculated treatment. P and K accumulation in shoot was significantly increased at co-inoculation treatment compared to non-inoculated treatment. This pot culture experiment demonstrated that single and co-inoculation of B. iodinum RS16 and M. oryzae CBMB20 increased the early growth and nutrient accumulation of maize and sorghum-sudangrass hybrid.Key words: Brevibacterium iodinum RS16, Maize, Methylobacterium oryzae CBMB20, Saemnangeum reclaimed soil, Sorghum-sudangrass hybrid Effect of co-inoculation of Brevibacterium iodinum RS16 and Methylobacterium oryzae CBMB20 on the early growth of crop plants in Saemangeum reclaimed soil 2
