Byron and crew,

If I remember correctly, I was one of the culprits behind the frozen seed
discussion.

I'm glad you did your experiment. Exactly how did your freeze your seeds?
Did you freeze them in water (frozen mammoth technology) or just toss them
into bags and into the freezer?

If I remember correctly, the main argument for freezing the seeds was to
increase the number of years the seeds might stay viable. It sounds like the
germination rate for the freezing method you used didn't work wonders for
many of the seeds. I wonder if different methods would prove more reliable.

I haven't tried it yet, but just off the top of my head, it would seem there
would be less cell damage if the seeds were very dry when frozen. The
expansion of the water freezing would probably damage the seeds. No water,
no expansion. Also, if the seeds are very dry to begin with there would be
much less possiblity of freezer burn.

Just some ideas.
