I agree with David, there's no advantage, and possibly a disadvantage, to leaving them in the solution (or on paper towels) once they have started to, or have, germinated. I would plant them right away, but not everyone does.
Re gibberellic acid, that's one of the few methods I haven't tested. Several years ago a hybridizer told me he'd tried GA-3 on daylily seeds, having used it successfully on some other plant seeds, and although germination was prompt the resulting seedlings were stunted for a long time and, although they got going eventually, even by the next year they were behind in comparison to his untreated seedlings.
It's possible for some batches of daylily seeds to have little or no seed dormancy, and they'll germinate right away as soon as planted, no damp chilling or other pre-treatment needed to get them synchronized.. It's too bad we can't tell which they are in advance!
