The infection roots with arbuscular mycorrhizal fungi (AMF) can increase the efficiency in growth and nutrients uptake of plants. With the objective to verify this effect, the degree of colonization in rubber tree plantation cultivated in a Xanthic Ferralsol (dystrophic Yellow Latosol) and the efficiency of six AMF in colonization, growth and nutritional status of rubber tree seedlings were evaluated, with three and six months of transplanting. The results showed a low level of mycorrhizal infection and number of spores in adult rubber tree. Six months of transplanting of rubber tree seedlings were sufficient detectable AMFs infection. There was no increase in height, diameter and number of leaves. The foliar nutrients concentration (N, P, K, Ca, Mg, Cu, Fe, Mn and Zn) were also not influenced by the number of spores and infection degree, with only differences by age of the plants (three and six months of transplanting).
