Abstract

In this study, host-symbiont interactions between Eucalyptus camaldulensis seedlings and five isolates of ectomycorrhizal fungus Pisolithus tinctorius (Pers.) Coker and Couch in terms of colonisation and growth responses in vermiculite-peat at the end of 18 weeks were investigated. The treatment combinations consisted of five isolates of P. tinctorius (K55, PTE, PT3, PT7 and PT8) and four nutrient regimes (Ingestad's 2.5, 5.0, 10 and 20 mg I'1 P). Only isolate K55 resulted in considerable colonisation (up to 27% root tips mycorrhizal) that occurred at 2.5 mg l'1 P while the other isolates resulted in <1% colonisation. Colonisation by P. tinctorius K55 reduced growth in terms of shoot dry mass in E. camaldulensis seedlings. Regression of total dry mass of seedlings on the extent of colonisation was found to be negative.
