Host specificity of Dipterocarp ectomycorrhizal fungi

Patahayah M., . and Lee S. S., . (2003) Host specificity of Dipterocarp ectomycorrhizal fungi. [Proceedings Paper]

Dipterocarps are able to form ectomycorrhizas with a range of different fungi. However it is not known whether ectomycorrhizal fungi isolated from dipterocarp hosts could form ectomycorrhizas ECM with other ectomycorrhizcli host species. This study investigated the ability of two indigenous ectomycorrhizal fungal strains isolated from dipterocarps viz. Tomentella spp. and Pisolithus aurantioscabrosus to form ectomycorrhizas on seedlings of the exotic legume Acacia mangium in vitro. In nature A. mangium can form both ectomycorrhizas and arbuscular mycorrhizas. The result showed that both the indigenous fungal strains successfully formed ECM on roots of A. mangium. Tomentella spp. Produced characteristic ECM six days after inoculation while P. aurantioscabrosus ECM were produced two days later. Microscopic examination of hand-sections of the infected root tips formed by both fungi at the end of the study period showed the presence of a well developed mantle but a poorly developed Hartig net. Results from this study show that the fungi associated with dipterocarp ECM are not host specific thus providing useful information on the choice of fungi for use in ectomycorrhizal inoculation programmes.

Abstract

Dipterocarps are able to form ectomycorrhizas with a range of different fungi. However it is not known whether ectomycorrhizal fungi isolated from dipterocarp hosts could form ectomycorrhizas ECM with other ectomycorrhizcli host species. This study investigated the ability of two indigenous ectomycorrhizal fungal strains isolated from dipterocarps viz. Tomentella spp. and Pisolithus aurantioscabrosus to form ectomycorrhizas on seedlings of the exotic legume Acacia mangium in vitro. In nature A. mangium can form both ectomycorrhizas and arbuscular mycorrhizas. The result showed that both the indigenous fungal strains successfully formed ECM on roots of A. mangium. Tomentella spp. Produced characteristic ECM six days after inoculation while P. aurantioscabrosus ECM were produced two days later. Microscopic examination of hand-sections of the infected root tips formed by both fungi at the end of the study period showed the presence of a well developed mantle but a poorly developed Hartig net. Results from this study show that the fungi associated with dipterocarp ECM are not host specific thus providing useful information on the choice of fungi for use in ectomycorrhizal inoculation programmes.
