Re: HYB: storing pollen

In theory, Christy, that's all true.  But with 100% humidity here most
mornings when it's good hybridizing weather, I figure moisture can
instantly condense on cold pollen AND dessicant.  I wondered about it
last year, and seeing the note about having problems with pollen moved
in and out of the freezer made me decide not to do that any more.  I
suppose if I had all the pollen in one sealed container with dessicant
and I planned ahead enough, I could let it reach room temperature before
opening....easier just to store several little packets of pollen to
remove one at a time.

Some of the crosses I wanted to make were with blooms on the ridgetop
garden - no way to get up there quickly.  Once pollen is out of the
freezer, it wouldn't get back in for several hours.

Yes, Sandra, dry the anthers first for a couple of days, then freeze.  I
don't use dessicant because it's a losing battle in our humidity.  I dry
the collected anthers in compartment of a pill minder container under
lights to keep them dry, then put the pill minder container inside a
snaptight freezer container.

<Linda,    If you're storing the frozen pollen with a desiccant capsule
in the
                   container, it should last more than that! The biggest
culprit of lost
                   viability is moisture.

                   I've gotten some nice pods from pollen that's as old
as 2 years. Though I
                   try to work quickly and get the container back to the
freezer ASAP, a
                   container will be pulled out for use half a dozen or
more times over the
                   course of a season.


Now to go back in the pouring rain and hunt for the rest of those Tempo
