Storage of recalcitrant seeds of Eugenia brasiliensis Lam. under control of water availability [PDF]

Journal of Seed Science, 2023
: The reduction in humidity and temperature makes it possible to prolong the storage of seeds, except for those sensitive to desiccation (recalcitrant), which therefore cannot be included in ex situ conservation banks.
