The chapter "Working with Mycorrhizas in Forestry and Agriculture" by Mark Brundrett, Neale Bougher, Bernie Dell, Tim Grove, and Nick Malajczuk provides a comprehensive overview of mycorrhizal associations in forestry and agriculture. It covers various aspects, including the structure and development of mycorrhizal roots, the influence of root structure on mycorrhizal formation, and methods for identifying and defining different types of mycorrhizal associations. The chapter also delves into the taxonomy and biodiversity of ectomycorrhizal fungi, the management of collections as genetic resources, and the isolation and propagation of glomalean fungi. Additionally, it discusses techniques for examining mycorrhizal associations, such as clearing and staining mycorrhizal roots, measuring root colonization, and conducting bioassays. The chapter further explores the production of pure cultures of fungi and the synthesis of ectomycorrhizal associations, as well as the management of mycorrhizal plants in glasshouses, nurseries, and fields. Finally, it provides guidance on planning and conducting field experiments, including experimental design, data processing, and statistical analysis.The chapter "Working with Mycorrhizas in Forestry and Agriculture" by Mark Brundrett, Neale Bougher, Bernie Dell, Tim Grove, and Nick Malajczuk provides a comprehensive overview of mycorrhizal associations in forestry and agriculture.
