Abstracts |
Orchids are generally held to form a special kind of mycorrhiza, called orchid mycorrhiza. This association is formed between orchids and fungi of the form genus Rhizoctonia. Research on associated achlorophyllous orchids has shown that the orchid genera Corallorrhiza, Neottia and Hexalectris are associated with ectomycorrhizal fungi and usually exhibit significant specificity. Recent investigations on a few close relatives of the genus Neottia, including green orchids of the genera Epipactis and Cephalanthera demonstrated the occurrence of ectomycorrhizal fungi in their root systems. Stable isotope analysis provides further support for the hypothesis that both the achlorophyllous and the chlorophyllous orchids that associate with ectomycorrhizal fungi, obtain their carbon through nearby ectomycorrhizal plants via the ectomycorrhizal fungus. |
