The experiments were carried out (August to November of 1999 and 200) under greenhouse conditions in Embrapa Cerrados, Planaltina-DF. In the first assay, passion fruits (Cv. Marília-MSC) cuttings containing two internodes were immersed in IBA (indolbutiric acid) solution at 2000 ppm for 10 seconds and planted in expanded polystyrene trays, with 72 units containing eight organic substrates. The evaluation was made 90 days after planting, by determining the percentage of rooted and budded cuttings and the incidence (% of died cuttings) of Colletotrichum gloeosporioides. The Plantmax Florestal Estaca<FONT FACE=Symbol>Ò</FONT> exhibited higher level of budding and rooting and lower incidence of C. gloeosporioides compared to the substrate Plantmax Hortaliças<FONT FACE=Symbol>Ò</FONT>. The Nutriplanta<FONT FACE=Symbol>Ò</FONT> combined with Osmocote<FONT FACE=Symbol>Ò</FONT> was more efficient than the Plantmax Florestal Estaca<FONT FACE=Symbol>Ò</FONT>. In the second assay, the cuttings of hybrid RC1 ((F1: Marilia X Roxo Australiano) x Marília) were collected in August 2000 and treated with 2000 ppm of IBA. The organic substrates used were twelve. The results indicated that the rooting level of RC1 cutting was similar for all substrates. The addition of 1g of Osinocote per cutting, 30 days after they were planted in substrate plantmax florestal estaca, prorrided the better development to aerial portion for the RC1 hybrid.
