Canola Plant Growth Promotion by a Selected Plant Growth Promoting- Rhizobacteria, Burkholderia pyrrocinia Strain 13-1 in the Cold Condition

*Division of Agriculturral Microbiology, National Academy of Agricultural Science, RDA Suwon 441-707, KoreaPlant growth-promoting rhizobacteria (PGPR) are beneficial native soil bacteria that colonize plant roots and result in increased plant growth. The objective of this study was to determine the plant growth promotion in canola plants by selected PGPR strain 13-1 under low temperature condition. The seed treatment of strain 13-1 was enhanced plant height and root elongation on canola plant at low temperature condition. This result determined that a selected strain of PGPR can enhance plant growth and root propagation under extremely low temperature conditions. Thus, this PGPR strain extends their role on plant growth promotion on canola until low temperature condition for practical applications.
