sometimes, Pond apple is a decent rootstock for Atemoya. It depends on several factors, like the variety of atemoya you have, the variety of pond apple you have, and your soil conditions (drainage in particular)
...
I think for commercial growers, that would be a lot of dependencies and therefore a lot of risks.
yes I agree...
with that said, I seldom graft atemoya onto A. glabra.
but i do have the variety that was mentioned by Har (in the articles I posted), which is more compatible.
and I have grafted many annonas onto these pond apples with good success, including the Dream.
I think it could be a great rootstock for a dooryard grower who has a lot that is too wet for growing atemoya, maybe somewhere in south FL.
even if the tree dies in less than 10 yrs...having 5 yrs of fruit production in a spot that would normally be useless, is of great value.
just keep in mind...some atemoyas are more compatible with annona glabra than others, even if the A. glabra is a highly compatible variety.
