The main part of a successful production of passion fruit is dependent on seedling quality. The present research had the objective of comparing methods of passion fruit seedling production. The treatments were: 1- seedlings formed in plastic bags, filled with fertilized soil, and fertirrigated weekly; 2- seedling formed in rigid plastic tubes, filled with commercial substract, kept on a bench and receiving the same fertirrigation as treatment 1; 3- As treatment 2, but the containers were polystyrene trays; 4- As treatment 3, but the seedlings were not fertirrigated, and were placed into a "floating" system every two days; 5- Same as treatment 4, but the trays were kept throughout the period inside the "floating" system. The experimental design was completely randomized with five treatments and four replications. In the greenhouse, the experimental arrangement was composed of 64 plants. Each plot of eight plants was evaluated weekly, for the following variables: 1- plant height; 2- root length; 3- shoot dry weight; 4- root dry weight. After this period, the remaining seedlings were taken to the field for plant survival (%) and development analysis. In this second stage, the experimental arrangement was composed of 5 plants per plot. In the greenhouse, the trays kept in the floating system (treatment 5) showed the highest averages for all the variables, except for root length, for which the highest average was found for seedlings kept in plastic bags (treatment 1). In the field, a 100% rate of succeeds was observed for all treatments, and plants from treatment number 5 showed the highest average values for plant height.
