Jujube Pollination Question

[So_Cal_Mike]

Will Indian jujube (ziziphus mauritiana) pollinate Chinese jujube (ziziphus jujuba) and vice versa?

I've been attempting to hand pollinate an indian jujube seedling with pollen from three different chinese cultivars with no takes as of yet. It may be that the seedling Indian jujube is still too young or that the pollen is incompatible. I would appreciate opinions on the subject.

Doesn't the Indian jujube set fruit on its own?
It seems more finicky than the Chinese jujube although the Chinese one also aborts a majority of flowers.

Are you watering them enough? Jujube is drought tolerant, but not fruit-bearing if they don't get enough water.

[So_Cal_Mike]

Yes, I believe I am giving it sufficient water. It is in a #5 nursery pot, looks healthy and
is growing and flowering, just not fruiting

Still, I am curious about the pollen compatibility question between The Indian and Chinese
jujube.

Probably.   The only significant difference between the two types (Z. Jujuba vs Z. mauritania) seems to be with the leaves.  You can even graft one onto the other successfully.

Maybe see who has experience with growing jujube in containers.

I transplanted my Chinese jujube airlayer from 1 gallon pot into the ground this year and I'm already getting a few fruit set. A neighbor has a jujube tree so maybe that helped. But the trees are not that close in distance.

I have two Chinese jujubes in the ground (Li and Lang), and one in a container (Sugar Cane). That is what I am attempting to hand pollinate the Indian jujube with.

ajbb: That is interesting that the two are graft compatable, I hadn't heard that before.
