My experience with Amorphophallus seeds is that they should not be 
allowed to dry out, and should be sown as quickly as possible. There are 
people on the list who have germinated far more of them than I have, 
including this species, and I hope they'll comment (I've never tried 
this one from seed). I wouldn't expect any Amorphophallus seed to need 
refrigeration, but have no clue whether some might tolerate it.

Many species germinate pretty quickly when sown fresh, but this link 
mentions A. kiusianus as one that doesn't:…
