- Abstract
The mycorrhizal associations in 47 indigenous Tanzanian trees and shrubs, mainly from less humid areas, were studied. Forty species were found to be endomycorrhizal. One, <em>Uapaca kirkiana Müll</em>. Arg. (Euphorbiaceae) was ectendomycorrhizal while six, four <em>Brachystegia</em> spp., <em>Julbernardia globiflora</em> (Benth.) Troup. (Caesalpiniaceae) and <em>Monotes elegans</em> Gilg. (Dipterocarpaceae), were ectomycorrhizal. The results demonstrated a dominance of endomycorrhizal species, which is typical for the tropics and is further reinforced by taxonomic considerations. However, in the Miombo (<em>Brachystegia--Julbernardia</em>) woodlands, a major ecosystem in East and South Central Africa, ectomycorrhizal trees predominate in volume. In three other ecosystems studied -- a <em>Combretum</em> woodland, a groundwater forest and a semi-evergreen forest -- ectomycorrhizal species were absent or almost absent. Nodulated leguminous species appeared to be more common in the fire-induced woodlands than in the closed forests.
