The production of shifts sweet passion fruit tree (Passiflora alata Curtis) is hampered by the presence of soils that, sometimes, doesn¿t tend to nutritional demand of the plant, needing, then, fertilization. The application of Arbuscular Mycchorizic Fungus (AMF) is a way to available this nutrients in the soil. It can take to a reduction of time of the shifts in vegetation house anticipating the transplantation for the field, increasing the growth, developing the biomass of the plant and the production of fruits of quality. The aim of this work was to analyze the growth of the shifts of sweet passion fruit according to the levels of concentration of this innoculus. The experiment was conducted in casualty entirely lineation (CEL) with factorial arrangement of 2 x 4, as: 2 innoculation treatments (Gigaspora albida Schenck & Smith and Scutellospora heterograma Nicolson & Gerdemann) x 4 levels of innoculation (without innoculus = WN/I 100 spores = N1, 200 spores = N2 and 300 spores = N3) whit 5 repetitions. In each 30 days after the innoculation were measured the height, stem diameter and number of leaves. After harvest (90 days) also were evaluated: leaf area, fresh and dry biomass of the air and radicular part, colonization of roots and density of spores of Arbuscular Mycchorizic Fungus. Plants of sweet passion fruit showed high Mycchorizic dependence when innoculated with Gigaspora albida, this fungus proportioned in the plants of sweet passion fruit better answers in relation to the evaluated parameters.
