10 years ago or more a fellow persimmon enthusiast, David Pierce, tried
and tried to root persimmon cuttings. He used various rooting compounds,
and chemical mixtures in his basement under controlled temperature and
light conditions. He managed to get one cutting to develop one root and
when he took it out of the liquid the root broke off. Under the right
conditions they will develop callous but I've never seen any developed
roots from the callous. They can be propagated in vitro and Prof. Paula
Pijut at Purdue University researched the subject and wrote a paper on
it. I have about a half dozen trees of Rosseyanka that she propagated in
vitro that have been in the ground maybe 10 years but haven't borne any
fruit. Acclamation (transferring from the test tube to soil) with
persimmon is a big problem.
