Abstract

Ultrastructure of Eucalyptus ectomycorrhizas initiated by compatible, host-specific fungi and by broad-host range fungi was compared with that of roots inoculated with incompatible, conifer-specific ectomycorrhizal fungi. The results indicate little difference in morphology between ectomycorrhizas formed by compatible, host-specific fungi and those formed by broad-host-range fungi. However, interaction between eucalypt roots and incompatible fungus species known to be conifer-specific induced either deposition of tannins in root tissue or, in the case of the Pseudotsuga-specific Suillus lakei, a characteristic hypersensitive reaction which resulted in lysis of hyphae and of epidermal and outer cortical cells of roots.
