The only hormone I've heard of anyone trying with daylily seeds is gibberellic acid. My recollection is that the results weren't especially good, but I'd have to look up my notes. Let me know if you're interested and I'll find the reference.
It would help to know what you're finding confusing about seed dormancy, Christy. The easiest solution is probably to just do what you've done and plant them. If they have seed dormancy some may take weeks or months to germinate, so don't throw away the medium if you want to give them all a chance and you haven't seen as many seedlings as you planted seeds. Damp chilling (or peroxide soak) just speeds things up so you don't have to wait for stragglers.
Seed dormancy is just the plants way of not having all its eggs in one basket. Staggered germination prevents all the seeds/seedlings from being wiped out at once by some catastrophe. Seeds that respond to stratification experience a winter (fridge or outdoors) and then a spring (room temperature or warmer temps outdoors). That sequence clues them in that it's safer to germinate all at once because they have the whole warmer growing season ahead of them to get big before winter, whereas germinating in fall would be hazardous to their survival.
Not sure if this helps or makes it even more complicated!
