The initiation of a programme of screening and selection of arbuscular-mycorrhizal fungi (AM fungi) and ectomycorrhizal fungi (ECM fungi) for use as inoculant fungi in agriculture, horticulture of forestry will depend on whether inoculation is more appropriate as a management option than manipulation of the indigenous mycorrhizal populations. The greatest immediate potential for the successful use of mycorrhizal inoculants will be in soils and growth media where phosphorus (P) limits plant growth and where the indigenous mycorrhizal fungi are either ineffective at increasing P uptake by the plant or their numbers have been drastically reduced by human influence or natural disturbance. In recent investigations, however, additional benefits to the plant following colonization of roots by effective AM or ECM fungi have been demonstrated. These additional benefits of an effective mycorrhizal association have necessitated a re-evaluation of the optimum screening procedures for isolates of AM and ECM fungi. Both current methodologies and suggestions for alternative approaches to the screening of AM and ECM fungi are discussed in this paper. The problems inherent in choosing suitable experimental conditions to compare different isolates at the screening stage are also addressed. The review also stresses the importance of continued monitoring of introduced mycorrhizal fungi to learn more about their longer-term ecological role, particularly within reforestation or revegetation studies.
