Abstracts |
A greenhouse experiment was conducted to evaluate the effects of arbuscular mycorrhizal fungi (AMF) inoculation and phosphorus fertilizer application on mangabeira (Hancornia speciosa) seedlings. The treatments on the native soil from the H. speciosa orchard include: fumigation with methyl bromite and non-fumigation; six rates of P (3*, 3, 48, 93, 138 and 183 mg/dm3); and AMF inoculation with Gigaspora albida, Glomus etunicatum and uninoculated control, with four replicates. The treatment 3* did not receive nutrient solution, while the others received Hoagland nutrient solution without phosphorus at the time of inoculation. After 150 days, a significant increase on height, shoot biomass and leaf area were observed in the treatments with Gigaspora albida in fumigated soil. A positive response to inoculation occurred in seedlings cultivated in soil with lower phosphorus rate, in both soil treatments. H. speciosa was mycorrhiza dependent only when in fumigated soil and at the lowest phosphorus rate. In treatments at other rates, the dependency varied according to the AMF and soil condition. The association with G. albida enhanced the growth of H. speciosa.. |
