A pot experiment was carried out to study the effects of two species of VAM fungi (Glomus sp.)on the vegetative growth and physiology of tea trees(Camellia sp.) and the quality of tea. The results showed that infection of host plants with mycorrhizal fungi markedly raised the activity of phosphorylase in the soil and the dehydrogenase of their roots, promoted the absorption of P, Cu and Mn, and increased their growth volumes and rates. In addition, the contents of chlorophyll and coffeine increased, but the activity of peroxidase and the contents of Fe and catechins reduced.
