Re: fern spores available

Hello
In reply to Valerie, I am very interested to hear about your activities in
storage of spore.
We run a specialist ferns nursery here in New Zealand & over the years
worked on different methods to store spore.
This has come about due to the ideal of being able to sow small lots of fern
spore on a regular basis over the season, until we can once again go &
collect fresh spore.
We have definitely found with our NZ native fern spore that viability
quickly decreases with age.
At present we are bleaching the spore then measuring out small spots into
test tubes fill of distilled water.
We then place this in a dark turned off fridge.
We have been doing this now for a season so evidence to prove its usefulness
is not conclusive as yet, but starting to see some good results.
The whole issue of collecting viable spore is something I have alot to learn
about.
Interested to hear anyone's comments on this subject.
Regards
