Oryza sativa - Opis:
- The use of plant growth promoting rhizobacteria is increasing in agriculture and gives an appealing manner to replace chemical fertilizers, pesticides, and dietary supplements. Th e objective of our research was to access the plant growth promotion traits of Pseudomonas aeruginosa, P. fl uorescens and Bacillus subtilis isolated from the maize (Zea mays L.) rhizosphere. In vitro studies showed that isolates have the potential to produce indole acetic acid (IAA), hydrogen cyanide, phosphate solubilisation, and siderophore. RNA analysis revealed that two isolates were 97% identical to P. aeruginosa strain DSM 50071 and P. aeruginosa strain NBRC 12689 (AK20 and AK31), while two others were 98% identical to P. fl uorescens strain ATCC 13525, P. fl uorescens strain IAM 12022 (AK18 and AK45) and one other was 99% identical to B. subtilis strain NCDO 1769 (AK38). Our gnotobiotic study showed signifi cant diff erences in plant growth variables under control and inoculated conditions. In the present research, it was observed that the isolated strains had good plant growth promoting eff ects on rice.
