Hi Robin. Then I suppose you'll be probably be among the first to find out, how quickly it can be done. . I noticed the the cleaning agent, for the seeds, was actually Potassium hypochlorite, by the chemical formula , which was given, as the "cleaning" agent, used. They named it as Calcium instead, but according to letter, as used in the Element Chart, as K, which is Potassium, ( & not Calcium, which, is Ca... )
I suppose to help prevent mold, or fungus, ( from any growth,) on the seeds., before adding, "buffering agent", (to a ph 7- neutral) & rinsing, (likely with distilled water) then sowing.
Regular "household bleach", is sodium hypochlorite, although I forget off hand, the mol, measurement stated, in amount, used, if you know anything about Chemistry & bleach has to be rinsed off thoroughly & is really rather quite potent, unless diluted first, by adding to water. ( Never, to be done, by adding water to bleach !) Because it was only the 'Abstract" of the entire article published & didn't sign up for trial use of JStor, didn't finish the entire article...
Although, it explained results were achieved, with germination of ordinary garden variety crossing of bearded Iris seeds, starting in 78 days, after sowing.. Instead of 'harvesting fully ripe seeds" drying & soaking & then waiting for germination , until spring of the Next Year !
Then, I went on to read an old Forum post, about harvesting slightly "unripe "seeds & having no problem, with quickly germinating Iris ( koreana?) seeds, & doing so, because of the faster germination, by sowing while still barely ripe, immediately. Not, after the seeds, have already started to turn brown, either. As that just may be ,a little too late !
