The Tropical Fruit Forum

I saw that you did that! I've done an outdoor one already on my original Prague Chimera which was grafted to flying dragon and barely grows, so did the approach using standard poncirus this past summer and it took. It technically has 2 rootstocks at the moment which I will need to cut the FD in the coming season.

Here are those hybrids the Edulis that I named purple boots was the father, incarnata was the mother. I have 6 in total with 4 more unique plants that havent flowered yet






A 3rd plant is showing some buds so hopefully we'll see that soon.

Neither of the 2 that flowered held a fruit which could indicate sterility with its own pollen or female sterility

I wonder apprach grafting could work to induce a graft chimera from the callus tissue

Did anyone ever tried to approach graft cherimoya and paw paw ? I am interested in this as i have some seedlings of both i would likw to wxperiment with ??

Will be testing Iva grafts this winter here in NJ and update. 3 large grafts on a swingle that is against a retaining wall, and 1 graft on poncirus that is out in the open but also close to the roof of our garage (house is on a hill with garage at street level). I have seedlings from the Iva seeds themulberries sent me as well as dingle (somewhere lol) the Iva are in pots but I can't remember where I put the Dingle lol. I also have some troyer citrange x pomelo that are too small to plant so I'll test those next season. Those probably won't be hardy in z7a at all.

The same happened to me when I bought veinte cohol, they sent me dwarf cavendish. Where did you purchase it?
My orinoco didn't have the brown marking at any stage.

Sold as veinte cohol, def not lol

Saved some seeds from my Afganksi pom harvest this month Nov 2025, air dried they will last for about a year. I tested some seeds from last Nov 2024 back in September and some germinated at around 2 weeks with ziplock bag + paper towel method on top of fridge I didn't continue the test. These will be fresh from the 2025 batch.

The tree is hardy, has not died back at even 1f during a polar vortex. Fruit ripens in late October here in zone 7a.

Flavor is sweet + tart, arils become darker the longer the fruit hangs. Seeds don't come true but fruit should be similar ~3-5 years to see flowers.


I can fill some baggies around 20+ seeds

Not my heaviest (that one was 1.5lb)

Cool, would love to see the results on those seeds when you notice anything.

This winter, while outdoor gardening stops, I’m brainstorming a series of indoor experiments using oryzalin as a safer alternative to colchicine for inducing polyploidy. I’m especially interested in seeing how different species respond, both in growth and eventual fruit quality.

Some ideas working with seeds that I have or need to source:
Hindsii kumquat (my tree died from root rot this spring)
Fast flowering trifoliate,
Afganski pomegranate,
A large-fruit pawpaw (not really precocious but I don't see polyploid pawpaw varieties in the trade)
As well as doing targeted bud treatments on my Passiflora incarnata × edulis hybrid cuttings.

My goals are to explore whether polyploid lines can give improvements like thicker foliage, increased vigor, larger fruit, or in the Passiflora hybrid potential restoration of fertility where sterility is an issue. I think these trials could lead to some unusual phenotypes, maybe even new breeding material and a good way to kill time when it's freezing out.

Pollination issue? Dropping after they've opened? Root issues? Could be a handful of things

My vine is still growing but it never flowered. It's in a 5 gallon pot, already moved indoors for the winter.

Luis it sounds like you have great varieties. I don't think the members are saying you aren't trustworthy, it is just equally important to follow the quarantine and photosanitary laws.

Take this as an example someone imported decorative stones or the story goes- something innocent- from China and introduced the invasive laternyfly from egg cases that were on the stone. Now this pest has virtually no predators on the east coast USA and is having a great time multiplying. It is better to be cautious than pay for it later. 

Jsea when you mention major damage are you are you talking about the hardiness of the pseudostem and leaves recovering from cold damage? The hardiness I am interested is at the corm level, which will need to resprout after winter here like the musa basjoo does in the spring after freezing down to ground level.
