Ackee Fruit and Seed Question

[Lumi-Ukko]

I recently located a lone Ackee tree growing on the sidewalk here in Merida, loaded with fruit. Since it's on public property I grabbed a few open and unopen fruits to collect some seed. However, I found the seed to be very small and unlike the photos I find online.

On research, it would appear Ackee is dioecious. Is it the case then, that Ackee can develop fruit as a dioecious tree but if unpollinated, does not create viable seed? Picture of the fruit, but don't have one of the seed.

Supposedly there are hermaphrodite self-fruitful ones.  I got a grafted one from Lara Farms that is described this way.  No flowers yet though.  Not sure about growing from seed.

My Dad had an Ackee tree that fruited and produced full sized seed as a lone tree. I would be very skeptical of eating unpollinated fruits. I would think the aborted seeds might be harmful if left in and would be tedious to pick out.

Thank you for everyone's answers so far. I realized that if you zoom in on the picture on my first post, you can see in the opened fruit where the tiny small/aborted seeds are, just visible in the flesh. Of all the fruit I checked, they have been the same. I'm very curious as to why this would be. The tree is large and well-established, so it would seem that age is not the issue.

In my experience Akee is not dioecious.  Some seeds come small but that they all do is unusual.  It’s planted quite commonly here, pretty much all by side. We have production and I sell seedling trees in my nursery.  The fruit looks very good to me in the photo.
The small seeds won’t be difficult to remove.  The thing is to make sure that they are not overlooked.  Enjoy!

I actually just harvested some fruit in Playa del Carmen with the same characteristics. The difference in size wasn't clear to me either. I only planted the larger seeds.

Thanks Peter! Maybe I'll plant the seeds and see what happens nevertheless. It can't harm to try! Happy New Year!

Hi Daniel, long time no hear!  Interesting that you got mostly small seeds too, but at least a few larger ones. Perhaps I need to go bak and collect a few more fruit to see if I can find some larger seeds. If you do successfully germinate the small seeds, I'd be interested to hear.  Happy New Year!

I also harvest seeds from a lone tree. The tree is huge and produces hundreds
of fruit every year. The seeds are normal size and germinate fine. They actually
sprout under the tree on top of the ground. When you plant the seeds you don't
need to bury them. Just keep them warm and damp
