Pawpaw persons,
This is from: Dirr, Michael A. and Charles W. Heuser. The Reference
Manual of Woody Plant Propagation: From Seed to Tissue Culture. page
94

Assimina triloba, Pawpaw
SEED: Seed (usually 2 to 3, large, dark brown) should be removed from
pulpy matrix.  Delayed germination is caused by slowly permeable
seedcoats and dormant embryos. Interestingly, seed from a southern source
germinated 100% without cold treatment. Three seed lots, each given 2
months cold stratification, germinated 50%, 62%, 82%, respectively. Fall
sowing of untreated seed did not improve germination. Fall planted seeds
may germinate over a two-year period. Seedlings have a long
taproot.  

CUTTINGS: No report of stem cuttings being successfully rooted. The
authors have observed colonies of pawpaw not unlike those of sumac
(Rhus). It would seem that root cuttings might be successful.

GRAFTING: Professor Joseph McDaniel, University of Illinois, was a master
grafter/budder and successfully chip-budded (spring-summer) pawpaw
cultivars on established trees. Seedling understock would also 
work.
