So, my first question is whether or not there is a dwarfing/semi-dwarfing rootstock for American persimmons? Are they compatible with kaki or lotus rootstock? Texana? The various Asian cultivars reach a good size for me at maturity--if I could get a good-quality American in that size I'd be quite happy.

My second question: Will d. texana pollinate d. virginiana? There aren't any wild American persimmons in my area, but we're flush with Texas persimmons. Could the local pollen trigger fruiting?

Finally, anyone know the chromosome count of d. texana? I'm not finding that information anywhere online. D. virginiana and d. kaki, sure, but nothing for d. texana. Thanks!

I've grafted virginiana to both kaki and lotus and they grow and fruit well on each. I would expect that a kaki rootstock would have some dwarfing effect on the tree, but with the risk of various problems down the road, I don't think it would be wise to recommend kaki over virginiana rootstock for this application.

I believe texana has the same number of chromosomes as the southern virginianas, but I haven't heard of any hybrids between the two. Prok and Yates have an additional set of chromosomes, so they would be incompatible. These varieties don't appear to require any specific trigger to induce fruiting, so I would doubt that having no local wild virginiana would pose a cropping problem.
