Operational Ectomycorrhizal Fungus Inoculations in Forest Tree Nurseries: 1989
During the past 15 years, the mycorrhizal research and development program has evolved to the practical, efficient, and cost-effective application of the ectomycorrhizal fungus, Pisolithus tinctorius (Pt), in both container and bare-root nurseries. The benefits of Pt in reforestation, mineland reclamation, and Christmas tree production include significant increases in nursery seedling quality (reduced culls), and increased survival and growth in field outplantings. Four types of commercial inoculum are currently available, including vegetative mycelium, bulk spores, spore pellets, and spore- encapsulated seeds. Custom equipment has been developed and is commercially available for the operational application of vegetative inoculum in bare-root nurseries. The demand for custom-grown, Pt- inoculated seedlings for an expanding variety of forest applications continues to increase. Approximately 6.5 million seedlings were inoculated with Pt in 1989 in bare-root and container nurseries in the Southern, Central, and Eastern United States. Technology is being expanded to other ectomycorrhizal fungi, host tree species, forest applications, and geographic locations.
