These normally don’t have three sections it seems. [IMG_0113] [IMG_0114] [IMG_0115]

Well! You got me to go to my freezer and look at the ginkgo nuts I have stored there. You are correct, they normally have two sections. This is a thing that happens in plants sometimes: a developing flower or fruit will, by accident, come out larger or smaller than normal. When that happens, instead…

Wow, thanks, that’s really interesting!

@jasonhernandez74 I have to smile at the idea that you have ginkgo nuts in your freezer! :grinning: Are they for research purposes or are they edible?

Out of 24 ginkgo fruits I collected from a single tree last year, 2 had seeds that looked exactly like this. I believe this “deformity” is caused by the fertilization and successful development of 2 ovules within a single seed. Usually 3/4 ovules resulting from the meiosis of the female gametophyte …

Do you know any articles that support this? I was collecting seeds and noticed around 8% of seeds form 3 sections instead of 2 (and occasionally i have found a disfigurement where it doesn’t fully form 2 shell sections). Anyway I found this very interesting and wanted to look deeper into this. Any r…

Sorry I have no references except prior knowledge from biology videos and courses. It is interesting that the proportion of tripartite seeds you found is similar to mine (2/24 = 1/12 = 8.25%).

I found the reference to "the weak compound middle lamella " in this article on gingko seed mechanical design interesting. https://pubmed.ncbi.nlm.nih.gov/36442101/ It’s conceivable such a structure can respond to stresses by atypical growth development.
