How long, and how, to hold jackfruit seeds before planting

[Daintree]

So I bought a fresh Sweet Thai jackfruit at a local Asian market. It is now ripe, but my tree pots won't be here until Friday. How long can I hold the seeds, and how? Wet paper towels?

Thanks!

I'd just pop them in a tray with some water. They'll be fine for a while and will germinate in the water if left long enough. Waiting till Friday shouldn't be a problem.

Thanks!
Got the fruit cooked slightly in brown sugar syrup with spices for ice cream, the cut seeds for hummus, the scraps for my composting worms, then the plantable seeds later this week.

They can technically go in the fridge.
But if you just keep them moist
with a bit of vermiculite or perlite or something even sand or old dirt,
it's fine

Can I just wait for seeds to dry completely and store them for 5 years like Squash, Corn & Bean Seeds?
It's not like Jackfruit seeds die apon drying out right?

They will die after drying out!
Must be kept moist at all times and planted out asap.

I’d start them in any tray or wide pot as a group, then transfer to individual pots as they germinate.  They should be kept moist but I would not keep them submerged in water.  I think it’s best for seeds to begin rooting into a medium similar to what they will eventually be planted in.

Dang... why are jackfruit seeds so weird? Is there any Artocopus species that can dry their seeds and not die? Mulberries & Figs are from the same family so why is jackfruit so weird?
Do you know what's causing jackfruit to die apon drying? Is it a lack of seedcoat, exposed embyro, or something else? I'm hoping theirs a way I can breed a jackfruit to have viable dry seeds.

Also once fully dried, no amount of soaking them in water will help?

I've been told Pawpaw seeds also die apon fully drying out but I've managed to germinate fully dried seeds somehow, I'm know almost nothing about jackfruits but is it possible they work the same way?

No papaya seeds are fine dried out and will germinate up to a years later from my experience . Lots of seeds are not and will not germinate after loosing the moisture content in the seed

Professor, I don’t know what you mean by weird.  I have an extensive collection of fruit trees and the vast majority are recalcitrant.  The fruit most commonly talked about on this forum, the mango, cannot germinate from a seed that has been completely dried out.  Not too sure about your use of the word “weird” for most of the seeds we work with.

Many gardeners who have not gardened in tropical areas get a big education. Tropical fruit trees seed themselves right after fruit drops and grow immediately. Temperate fruit have adaptation that allow them to overwinter and grow during following springtimes or summers. Tropical fruit trees don’t need this adaptation. It’s pretty simple.
Best time to plant jak seeds is right after harvested from fruit. Many times they already growing in the ripe fruit,in this case the seed should be handled with care when planting and not break off the tap root.

I've never gardened in tropical areas, I don't even own land to garden, my experience has been mostly foraging/wild gardening. Maybe weird isn't the right word, it's just sad the jackfruit seeds have to die because I can't grow them now (All I can do is Save the seed by not trowing it away). I was hoping preserve some jackfruit genetics so that i could eventually try grafting Jackfruit onto Mulberry & vice versa.

How strong is the recalcitrant trait and is it some we can breed out/select against? Is the recalcitrant seed trait only for plants that lack a seedcoat (Idea being seedcoat preserves the embyro for dry storage)?
So far from experience, Citrus & Java Plums seeds literally fall apart into dust when fully dry and thus 100% recalcitrant (Will Jackfruit also crumble too?).

For example Chayote (Sicyos edulus) lacks a seedcoat while the wild Chayote (Sicyos angulatus) has a seedcoat, My plan is to cross the seedcoat trait into Chayote (Sicyos edulis). I'm hoping I can do the same with Jackfruit, exploiting horizotnal gene flow via Mentor Grafting & Mentor Pollination to transfer the viable when dry seed trait into Jackfruit from mulberry (Unless you know of a different Artocarpus species with viable seeds when dry). Since Mulberries dry find & store well.

Help me understand why anyone would need viable dried Jack fruit seeds.

@DavidBYE
To store Jackfruit seeds for longterm, how is this not a feature available? Wet storage doesn't last as long as dry storage.
It's a big shame this isn't a feature.
