The objective of this work was to study the reproductive systems, pollen viability, and pollen?pistil inter-actions in 11 species of Passiflora. The reproductive systems were evaluated by the pollen/ovule ratio(P/O) and field pollination. Pollen viability was estimated by in-vitro germination of pollen grains andthe colourimetric method with 2,3,5-triphenyltetrazolium chloride (TTC) and the pollen?pistil interac-tions through aniline blue fluorescence. According to the P/O ratio, Passiflora suberosa, Passiflora morifolia,Passiflora capsularis, and Passiflora tenuifila were classified as obligatory autogamous, Passiflora foetidawas classified as facultative autogamous, and the other species as facultative allogamous. Controlledpollination under field conditions identified six self-incompatible (Passiflora edulis f. flavicarpa, Passi-flora gibertii, Passiflora muchronata, Passiflora galbana, Passiflora racemosa, and Passiflora edmundoi) andfive self-compatible (P. tenuifila, P. morifolia, P. capsularis, P. foetida, and P. suberosa) species. Interspe-cific hybridisations were successful for some combinations, and the fruits obtained produced fertileseeds. Regarding pollen viability, there were different responses among species. P. capsularis showedthe highest in-vitro germination (80.1%) and stained pollen grains (96.2%). In self-incompatible species,the pollen?pistil interactions showed pollen tube inhibition due to the irregular deposition of callose,while, in self-compatible species, regular deposits of callose were observed. The results obtained fromstudies of the reproductive biology can aid in planning crosses and establishment of Passiflora breedingprograms using compatible genotypes with expressive ornamental potential.
