Dear all,

I might add that if you try to freeze pollen that contains moisture, you 
are guaranteed to destroy the pollen.  The moisture expands on freezing and 
ruptures the pollen grain.

For long term storage, almost all pollens retain viability longer at lower 
temperatures -- that is simple straight-forward biochemistry.  Dr. Robert 
Carr (Ocala, Florida) made careful studies of drying time vs. viability 
lifetime using Hemerocallis.  In all cases he stored the dried pollen in 
the freezer.  He found partial viability lifetimes for the most thoroughly 
dried pollen samples of several years' time.

Hippeastrum pollen keeps about 12 months if dried thoroughly and then 
frozen.  Clivia pollen keeps for several years.
