For the other species, all seeds that were stored at room temperature declined its germination percentage with time, as has been reported for T. flexuosa and T. fasciculata (Zotz, 2013b).
Where seed germination percentage followed a quadratic pattern, it began to decline abruptly after 200–250 days (T. achyrostachys) and 250–300 days (T. schiedeana).
Both species concur with our hypothesis, and seed germination percentage decreases at the end of the rainy season or over the next dry season following dispersion.
The early and constant decline of seed germination in T. circinnatioides, T. recurvata and T. hubertiana suggest that these species must germinate at the beginning of the rainy season or following the first three months of rain (middle rain season).
However, since we studied seeds stored under laboratory conditions, where fluctuating seed hydration and temperature differ from conditions in the tropical dry forest, the longevity of the species studied could be less.
