Abstract

---

Five strains of Frankia isolated from root nodules of Casuarina glausa collected from different localities of Islamabad were characterized by the occurrence of branched and septate hyphae bearing spongia and vesicles typical of Frankia. The strains showed marked differences in their growth requirements, growth rate, nitrogen fixing ability, production of pigments and infectivity of host seedings, CAQP1 and CAQP2 strains infected C. glauca seedlings while CAQP3, CAQP4 and CAQP5 failed to induce nodules on the host.
