Resume Introduction - Conservation and management of recalcitrant-seeded species are a major concern, particularly for socio-economically important species such as Synsepalum dulcificum in which seed viability and storage behavior are not sufficiently documented. Materials and methods - In order to improve the seed propagation management of S. dulcificum, we investigated the effects of seed provenance, short-term storage, culture medium, and pulp removal on viability, germinability, germination speed, and seedlings growth. A first experiment following a complete randomized block design consisted of two treatments (intact fruit or depulped fruit). In a second experiment we used a split-split-plot design with 16 treatments of a factorial combination of 2 provenances (Houéyogbé and Toffo), 2 culture media (soil and sawdust) and 4 storage times (0, 1, 2, and 7 days). Results and discussion - The seed viability remained high (85%) on the second day of storage at ambient condition and decreased to 0% when seeds were stored for 7 days. It was affected by the type of culture medium. All factors, except pulp removal, affected germinability and germination speed with percentages ranging from 44 to 99% at two months after sowing. Seedling growth was extremely slow and was affected by the seed provenance, substrate, and storage time. Conclusion - The time of storage is a major limiting factor for S. dulcificum seed viability whereas successive use of sawdust and soil for germination and seedling growth, respectively, is recommended to improve seedling production in the nursery.
