I believe they use Hydrogen peroxide to wake up Protea seed, at least
that
is what I was told to do.

There has been some success with it, but the best thing to use is smoke
(as smoke water or paper discs which have been exposed to smoke, rested on
the seed compost, and gently sprayed to allow the smoke to soak into the
compost).

that's enough, Jeff. If you want to be cruel I'm not allowing it.

It's very unlikely that smoke germination would be appropriate for
Alder, if that's what you think Jeff is suggesting. It's an
evolutionary adaptation by plants exposed to wild-fires. Many South
African and Australian plants respond well. It may be because young
seedlings won't survive a wild-fire, but after fire has swept through,
there's nothing left to burn, and seedlings can get established to the
point at which they stand a chance of surviving the next fire.
Chemicals in the smoke trigger the germinating process.

I've used it myself on a number of occasions to encourage germination
of South African proteaceae (as Jeff said) and SA heathers. Can't say
how successful it was though, because I didn't do an unsmoked test
alongside it.

This idea of smoke to kill fungi, and maybe ME, is a nasty turn in
this thread. But I workng with a partner in another project, to grow
sequoia

I don't know how this thread became OT. I was just replying to Bob's
message on waking up Protea seed. As Chris said, it can be used
successfully for SA, and in my experience, Western Australian proteaceae
seed. I doubt it would have any beneficial effect on alder seed, and
might inhibit it from germinating. AFAIAA smoke had no effect on fungi.
