Isolation and Screening of Multifunctional Plant Growth Promoting Rhizobacteria (PGPR) from Onion Rhizosphere (Allium cepa)

摘要

Plant Growth Promoting Rhizobacteria (PGPR) can enhance the growth and productivity of plants through direct and indirect mechanisms. In this study, rhizobacteria were isolated from onion rhizosphere and their plant growth promoting activities were studied. The investigations of activities include: nitrogen fixation, phosphate solubilization, zinc mobilization, hydrogen cyanide and indole-3-acetic acid production abilities. Plant growth promoting rhizobacteria (PGPR) influence plant health and productivity by various ways. It can be summarized that the isolated multifunctional PGPR strains may have potential to be successful bio-inoculants for onion plant.
