I didn't realize that and I really don't know, honestly, what the species is I have. This seems like what the rollinia here is, if that's any help at all: Biriba

I think you are referring to this plant?

Reading a bit further, I found that about 10 years ago Rollinias were reclassified as Annona. So the plant in question is listed here along with its synonyms: Annona mucosa information from NPGS/GRIN

I don't have information on Annonacin levels in the fruit. But I did find this interesting article on a simplified method for checking directly from fruit pulp:
http://www.mdpi.com/1420-3049/14/12/5235/pdf
The Ag lab at the HILO GRIN repository would probably do this for the usual fee, or perhaps you have access to other resources.
Once the concentration is known, it can be compared to the published conc. of soursop.

how did you arrive at those numbers? i've read that a fruit a day over the course of a year is enough to produce effects, but then there are so many other factors that need to be taken into account (cultivar, environment, etc.). i am sure a guanabana grown in the tropics could equal the effects of 10 grown in the subtropics. i am just curious, because 2 /year probably isn't going to cut it for me.

i personally don't think i could cut it out of my diet. my family grew up on soursop in the islands, so the reward of a good soursop every once in a while exceeds the perceivable risk to me.

Analysis of peer-reviewed published papers and knowledge of neurotoxicity.

Personally I don't believe that. In one paper, the tested conc. of annonacin in cherimoyas grown in Costa Rica and southern California were statistically identical.

But Merce, I'm not trying to convince you one way or another. Instead I'd like other readers to have a balanced presentation.

i meant you as in you guys or you two...

i am just trying to weigh the risk, but it's hard to get a balance of info without knowing which articles you are referencing. i appreciate your knowledge, but i think the risk is over-exaggerated. the articles that i have read (published and peer-reviewed) associate larger amounts with side effects and 2 soursop versus 365 a year is a huge difference, so i am trying to bump that number up to say ~300 /year?

at least cherimoyas don't grow here because of the environmental differences, so i guess i don't have to worry about those. then again the dream atemoya that i have growing closely resembles cherimoya, so i'm not so sure...

Ponderosa lemon and limequat. Both were purchased in December as was the Sunrise blueberry; all have fruit on them! I love this instant gratification FL gardening.

We had a very mild winter and are about 3 weeks ahead of where we should be. The crocuses are long finished but tulips and daffodils are everywhere. My arctic kiwis are developing blossoms and both the peach and pear trees are already blossoming. Even my dragon's claw arum is about 6" above ground (on it way to an eventual height of well over 4ft)

My Grimal jaboticaba was blooming over the last few days. Didn't manage to get a photo of it in bloom, but here's one from a day or two before the flower buds opened.

Looking good!
What is the origin of your Grimal jaboticaba?
