I use 1 1/2 teaspoons of 3% H2O2 per cup of water and soak them overnight. I have also used straight 3% H2O2 for ten minutes. However, I think it really works best on hard seeds. I wouldnt try it on recalcitrants seeds, since utlimately the reason it works is becuase it destroys cell walls.
I dont know about the others, but the annonas should be good candidates for overnight soaking.
I also use 1 tablespoon of H2O2 per cup to spray on seedlings to prebvent damping off.
The use of different H2O2 strengths and lengths of soaking have long been the source of school science experiments, so if you have enough seeds, you can always conduct your own research! I am thinking of doing just that on my hundreds of jacaranda seeds, where I am getting a germination rate of about 5%...
