Abstract

Eucalyptus species are of great importance to plantation forestry and play a significant role in world timber supply. Some 460,000 ha of Eucalyptus plantations have been planted in China, and about 60,000 ha are established each year (Bai & Gan, 1996). However, successful plantations of exotic eucalypts in China may require inoculation of nursery plants with effective mycorrhizal fungi, since the diversity of ectomycorrhizal fungi in eucalypt plantations in southern China is low (Dell & Malajczuk, 1996; Gong et al., 1997). Eucalypt trees form ectomycorrhizas (ECM) and the anatomy, morphology and ecology, as well as physiology of these associations have been extensively studied (Brundrett et al., 1996). Eucalyptus seedlings are capable of forming both ECM and vesicular-arbuscular mycorrhiza (V AM), even on the same root system (Brundrett et al., 1996; Chilvers et al., 1987). Colonization of different fungi in the same root system commonly occurs in nature, but little is known about its significance. Tree seedlings with multiple mycorrhizas including both ECM and V AM fungi may withstand a wider range of site conditions than those colonized by one fungus.
