Arbuscular mycorrhizal fungi and phosphorus supply on seedlings of mangabeira
The objective of this work was to evaluate the effects of the association of arbuscular mycorrhizal fungi (AMF) and phosphorus fertilization on seedlings of "mangaba" (Hancornia speciosa). The experiment, at a greenhouse, was in a completely randomized factorial design with two treatments of the native soil from an H. speciosa orchard, fumigated with methyl bromite and non-fumigated, six doses of P (3*, 3, 48, 93, 138 and 183 mg dm-3) and three inoculation treatments, Gigaspora albida Schenck & Smith, Glomus etunicatum Becker & Gerdemann and an uninoculated control, with four replicates. The treatment 3* did not receive nutrient solution and the others received Hoagland nutrient solution without phosphorus, at the time of inoculation. After 150 days, high increment on height, shoot biomass and leaf area were observed in the treatments with G. albida, in fumigated soil. Positive response to inoculation occurred in seedlings cultivated in soil with the lower phosphorus level, in both soil treatments. Hancornia speciosa was mycorrhiza dependent only when in fumigated soil, at the lowest phosphorus level. In treatments at other levels, the dependency varied according to the AMF and soil condition. The association with G. albida enhanced growth of H. speciosa.

O objetivo deste trabalho foi avaliar os efeitos de fungos micorrízicos arbusculares (FMA) e da adubação fosfatada em mudas de mangabeira (Hancornia speciosa Gomes). O experimento, em casa de vegetação, utilizou delineamento inteiramente casualizado em fatorial com dois tratamentos de solo nativo oriundo de pomar com mangabeiras, desinfestado com brometo de metila e não-desinfestado, seis doses de P (3*, 3, 48, 93, 138 e 183 mg dm-3) e três tratamentos de inoculação, Gigaspora albida Schenck & Smith, Glomus etunicatum Becker & Gerdemann e controle sem inoculação, com quatro repetições. O tratamento 3* não recebeu solução nutritiva e os demais receberam solução nutritiva de Hoagland sem fósforo por ocasião da inoculação. Após 150 dias, observou-se aumento na altura, biomassa e área foliar nos tratamentos com G. albida, em solo desinfestado. Respostas à inoculação ocorreram nas mudas cultivadas com a menor dose de P, nos dois tratamentos de solo. A mangabeira mostrou-se dependente da micorrização apenas na menor dose de P em solo desinfestado. Nos demais níveis de P, a dependência variou em função do FMA e da condição do solo. A associação com G. albida proporcionou melhor desenvolvimento das mudas de mangabeira.
