Have access to some 30 year old (according to carer) Annonidium manii Jungelsop tree's  and want to vegetative propagate them. They have not set fruit so maybe pollination is an issue becuase there's plenty of flowers.
Please share advice on marcotting annonace or what type of species that could be suitable as root stock for a. manii.
Maybe there's a more common african annona that would be suitable as root stock.

a. manii is quite different form a. reticulata and a. muricata, sqamosa and soncoya,  so I don't know if those would work. But will try in the mean while.
And maybe in some time I have some to report myself :)

this thread had some usefull info but nothing on marcotting or rootstock etc.

there's a thread somewhere of people's experiences with grafting different annona species onto different annona root stocks - hope it helps

can't find it in the search but can find threads with questions of root stock for soncoya and reticulata for example.

I have heard that this species can be dioecious: separate trees for male or female.  Also have heard that some trees can be monoecious.

I tried grafting with fresh, leafy scion-wood from Bill Whitman's trees, in the 1990's.  I no longer remember details about the root-stocks, but presumably included Soursop and Mountain-Soursop.  None lived.

thanks for finding the link driftwood, definetly some usefull info there.

thanks for the input Guanabanus. Maybe all my friends tree's come from a single fruit (with same parantage) and thus not able to pollinate each other? and/or it's of the monoecious type as you have heard and none have the female flowers or working female parts. haven't studied the flower.
Ill try to take an image of the flowers if I can sync my visit with flowering.
Will try Soursop and mountain soursop (a. montania I think) but will probobly wait until I also have a african annonace plant to graft onto.
A. spinesences I know of and can get but the tree and fruit is not similar at all so maybe it won't work.
Maybe Annona senegalensis? Don't have access to seeds yet.

Probobly have to find other genetic material of a. manii to get fruit becuase if my friends tree's in the highlands haven't borne fruit I doubt they will fruit here in the lowlands.

So nobody thinks it could be worth trying to air layer?

It's just that I am not sure how I am gonna keep the root medium moist, my friend won't water it and he's quite some distance away.
So if anyone know a method that is kinda "maintanance free" or keeps moist for a while, that would be great :D
Maybe if I try and do it in the wet season and leave some holes where rain can enter...

"30 years and no fruit, wow" That's what he said, will measure the girth once there.

Can try stenophylla also but it looks like a shrub like annona.

You might end up waiting another 30 years using this method but I found this site saying it’s possible to propagate via leaf cuttings

https://www.google.com/amp/s/innspubnet.wordpress.com/2021/03/11/research-paper-on-vegetative-propagation-of-anonidium-mannii-oliver-engler-diels-annonaceae-by-paluku-augustin/amp/

As for grafting compatibility, I wonder Søren would know anything about it? The flowers especially and fruit to a lesser extent look quite different from true Annona, maybe an African Duguetia might work?

Cross generic and intercontinental grafts? There are quite a few 12 to 8 year old ones around FNQ but don't know who has them. Just marcott, and if the 30 year old one has no fruit why bother? I heard loose talk around the traps around 10 years ago that there is a fruit one in NQ somewhere.

aka, you really found some info there, thanks! Will try that too in the wet season as this is probobly gonna be the best time to have a go at this and marcott. Postponeing grafting atempts until I'v got more then montana and muricata seedlings.

Mike, good there's some around of those but don't know anyone with a bearing a. manii yet.
Why bother with this fruit-less tree? thought maybe it will be a possible pollinator for another source of a. manii that I will be trying to get.

Another thing that probably hasn't been tried with this species outside of mid-Afrika, is to include Cobalt and Nickel and Vanadium in the fertilization, in imitation of many soils in Congo and surrounding countries--- to get healthier growth and fruiting.

Hi Guanabanaus, can give this hypothesis to my friend as he is into that stuff and knowlageable at it.
I would assume this would be applied in tiny amounts then.
Maybe I could compare a soil test from congo/ cameroon and see what our soil is in comparison. As a rough guide.

I assume these would be applied at the minuscule rates used for Molybdenum.  Or less.

For the Cobalt, one can use Vitamin B-12 (Cobalamin).
