Re: deep-freeze

Hello Valerie,
Thanks for your reply. The plants have been dried under normal atmospheric pressure, so not freeze-dried. Guinnea has a marked dry season, so the spores should be drought tolerant to at least some degree, I presume. So concluding it is not completely pointless, I'll give it a try, then.

William,

If the spores were dry when they were frozen, there is a very good chance that
they will survive and be viable.  It would only depend on whether the spores
are able to survive drying.  Most spores are desiccation tolerant (at least
when they are fresh), but I have not had any experience with spores from
equatorial Africa.
It's certainly worth a try, though.

Dear People,

We got some leaves with spores of Blotiella reducta, collected a month
ago in equatorial Africa. The leaves have been deep-frozen to discourage
animal trespassers. Would we still have any chance to have the spores
germinated?

kind regards,

Wim de Winter
