Are persimmon and black sapote graft compatible?

[Eric Estrada]

Anyone ever graft American or Japanese persimmon onto black sapote (diospyros nigra)? I have a fruiting black sapote and would like to graft any persimmon onto it. Both are Diospyros so if anyone has ever grafted black sapote onto a persimmon that would be helpful to me too. Thanks

This guy claims to have proof it can work.

I think I have heard of it, but not sure what direction, i.e. which was the rootstock.
Also Black Sapote is evergreen, but Kaki and American are deciduous.
However that is not an issue in Citrus ( deciduous Trifoliata rootstock under evergreen Citrus varieties, and the reverse combo is ok )
I think Kaki is compatible with some other Diospyros as rootstock. ( Date Plum and American )
Diospyros is also a very big Genus, and not all are closely related.
Some Australian Diospyros species seem close to Kaki in fruit and foliage, some quite different, some like mini Black Sapote.

Saw a black sapote grafted on a Fuyu persimmon at Leo Manuel's place.  Persimmon was dormant, but the black sapote was leafed out.
