Dear Dick;
Our friend & member Aaron Hicks, of the OSP, knows of several sources
about mycorrhiza and orchids, cited in his excellent orchid seed propagation
book. People are starting to cultivate mycorrhiza for commercial applications.
Are you propagating native Australian orchids? I have found that in my
rescue work in the USA. to incorporate some of the old soil from the rescued
mother plants into the new potting media and hope that the mycorrhiza will
multiply. So far so good, but I haven't tried this with Cyprepedium orchids. If
any of the members who rescue US. slippers would care to comment, I would
appreciate your input. Thanks.
Regards,

Hi all.
I would be very appreciative if I can get help in relation to orchids that
have been germinated asymbiotically and then introducing the mycorrhizal fungi
to the orchid when deflasking the seedlings.
Is anybody aware of any research that has been undertaken or other evidence of
the success or otherwise of these strategies.
The orchids I am working with are temperate terrestrial orchids that germinate
readily and grow well in the flask. But need the appropriate fungi for post
flask life. They can be germinated and grown symbiotically but there are
significant challenges in maintaining the correct nutrient balance within the
flasks so that the fungi do not consume the orchid seedlings.
Thankyou for any advice or direction towards published research that can be
forwarded.
Dick Thomson, Melbourne, Australia
