how?
And how long is it viable?
Thanks,

Hi Matt and all,
I have stored sundew pollen for only a few days within sealed vials in my
refrigerator. When sundew pollen dries it dies. I once put D. capensis
pollen in the freezer over night and used it in pollination and it proved
viable, so maybe it could be stored longer this way, I should study this
more. Dionaea, which I think of as a sort of sundew, has much larger
pollen grains than most sundews. Freezing kills Dionaea pollen, maybe by
internal freeze fracturing. I have only stored Dionaea pollen in the
refrigerator for a few days also. Things dry in the refrigerator too,
this is why it must be kept in a sealed container with high humidity.
During longer periods mold will grow, and this will also destroy the
pollen. To collect the pollen I use needle tip forceps to grasp the
stamen filament and pluck off the whole stamen. Then later after storage
I again pick up the stamen by the filament to dab the pollen onto
stigmas.
