Oxygen and seed germination

The technique of putting seeds in toilet tanks (UK "cisterns") is to
enclose the seeds in a nylon sock and lower them into the water for a
few weeks. I think it was mostly recommended for germinating
recalcitrant Iris seeds, particularly in the Oncocyclus section. I don't
know if it's in Deno's book, which has some helpful information but is
based on germinating seeds in controlled conditions that may be hard for
the home gardener to duplicate.
If I happen to be home when it snows, if it does, I'll try the snowmelt
trick again.

Hi,
There's been chat here in the past about putting seeds in toilet
cisterns so that repeated changes of water wash out any chemicals that
inhibit germination.
It also chimes with the thread about floating seeds to germinate them.
Surprising no one has made a seed washing machine.
Probably some answers in:
SEED GERMINATION THEORY AND PRACTICE; by Professor Norman C. Deno.
