In order to evaluate the pollen performance of Passiflora suberosa, in vitro germination of pollen in plants grown on greenhouse at Ilhéus, South of Bahia, was studied. Statistical analysis was performed considering a randomized experimental design, with six treatments that consisted of collection times, from 7:00 to 5:00. The germination element was the same used for yellow passion fruit, and the slides were incubated at 28°C (+ 1°C). There was a significant difference (P<0.01) among the six collect times tested, and among plants at 7:00 and 8:00, showing heterogeneity among the genotypes. The average percentage of pollen germination was negatively influenced by the later testing times. The greatest germination index was at 7:00 and 9:00.
