A simple UVF image of a longitudinal section through a pineapple (Ananas comosus). Some interesting patterns appearing!
Nikon D850 with 105mm micro Nikkor. 20 seconds @f/16, light painted with Convoy S2+UV torch.

Great side by side.
I may have to fldo series of a pinapple, the next time I cut one up.
I think the woody core would also have a nice IR fluorescence.

I did try a horizontal section, but the woody core didn't seem to fluoresce much

Interesting. I guess you can never guess!
A kiwi with a "wood like" core has IR fluorescence off the chart.
I will have to take a look at it.

But they are two totally different things, so just because they look similar doesn't mean they evolved the same.
