| Research Abstract |
This study investigated the interactions between AMF Glomus mosseae and PGPF Phoma sp. isolates GS8-2, GS8-3, Penicillium simplicissimum GP17-2 or Trichoderma harzianum GT3-2 for their colonization, plant growth promotion and disease suppression. Mycorrhizal colonization by G. mosseae in cucumber roots was enhanced by T. harzianum GT3-2, while Phoma sp. GS8-2, GS8-3 and P. simplicissimum GP17-2 had no effect. The effects of G. mosseae on the establishment of PGPF differ with the different PGPF species combined. Although, the colonization of Phoma sp. isolates was strongly suppressed by G. mosseae, T. harzianum was slightly affected. In contrast, neither the root nor rhizosphere colonization of P. simplicissimum was altered by G mosseae. The ability of Phoma sp. isolates to promote growth and induce systemic resistance was also adversely affected by G. mosseae, however, the same beneficial effects of P. simplicissimum or T. harzianum was not affected. Instead, the ability of T. harzianum to promote plant growth was synergistically enhanced by the presence of G. mosseae. Combined inoculation of P. simplicissimum or T. harzianum with G mosseae resulted in better suppression of the root pathogen R. solani, though such an effect was not observed on the leaf pathogen C. orbiculare.
