Here, 248 endophytic bacterial strains were isolated to assess the distribution and population diversity of endophytic bacteria in ginger plants. A total of 10.4 x 10⁴ to 20.2 x 10⁴ CFU/g fresh weight endophytic bacteria of different growth stages were isolated. Maximum bacterium numbers were obtained at the seedling stage. A total of 107 functional strains were screened, including 17 antibacterial strains and 90 indole acetic acid-producing strains.
