The knowledge of substrate effects, stages of fruits maturation and presence of the aril on the passion fruit seeds germination is importante for development of this culture. Therefore, the objective of this work was to study the germination and vigor of passion fruit seed on different stages of fruits maturation, substrate and presence of the aril. An experiment was set up on an entirely randomized design following a factorial arrangement of 2 x 2 x 3, with four replications of 25 seeds, in order to determine the effects of two stages of fruit maturation (ripe and withered), presence and absence of aril and three substrate (vermiculite, sand and soil+sand+dung (bovine). Evaluation were performed for the germination (%); index of emergency speed; normal and abnormal seedlings (%); hard seeds and deteriorated (%) and mass dries of aerial part and of root (mg). The seeds of (vermiculite, sand and soil+sand+dung (bovine). Evaluation were performed for the germination (%); index of emergency speed; normal and abnormal seedlings (%); hard seeds and deteriorated (%) and mass dries of aerial part and of root (mg). The withered fruits presented larger germination percentage, happening the same when it was made the removal of the arilo. The speed of emergency of the seedlings was favored by the planting of seeds of withered fruits with aril in the soil + sand + dung substrate.
