Abstract: (3227 Views)
Biocontrol of Fusarium oxysporum f. sp. ciceris by six Bacillus species was evaluated. Also plant growth promoting potential of the bacteria was assessed. Results showed that four bacterial strains produced the chitinase and cellulase enzymes and all isolates produced indole acetic acid. Bacillus licheniformis proved to be the most productive of hydrogen cyanide and particularly, Bacillus firmus solubilized phosphorus on Pikovskaya solid and liquid media. The majority of strains were able to produce siderophore and three produced NH3. Results showed that the Flip05-156C chickpea variety was less susceptible to Foc isolates compared to Flip93-93C and there was a clear difference in pathogenicity of the Foc isolates. Thus, Foc1 and Foc2 isolates caused 31.25% and 41.66%, plant mortality, respectively. As regards PGPR effect, results showed that B. licheniformis gave the best branching number, stem length and root weight of both chickpea varieties. However, Bacillus lentus distinctly improved the root length while Bacillus amyloliquefaciens improved weight of the vegetative parts.
