Poncirus fruit comparison
Jibro:
Thanks Jim for clarification, even if only one fruit was that big, it still shows the great potential that poncirus have for improving fruit quality. I think if someone crazy enough ;) will try to grow poncirus as fruit tree with a lot of fertilization, pruning and fruit thinning, fruit size may increase even further...
Btw I grow Spartan apple too it was very popular variety in the past here and I still like the taste.

That 7cm fruit was a real outlier; the 4-5cm fruits shown in the photo are more typical, with quite a scattering of smaller ones. I wish I'd taken a picture of the big one.
I have an apple tree called Spartan that does something similar. One year I got an apple that weighed very nearly a pound, whereas 2-3 fruit per pound is more typical. Why that happens is a mystery to me.
The seedless ones tend to be the small one, though I did get a couple largeish ones that were seedless.

Any updates from this tree?

Hi Bussone
No, nothing particularly new. The 2021 harvest was about the same as earlier ones, but with no 7 cm mega-fruit; the largest one was about 5.8 cm. Here's the image for that:
There really wasn't much of a 2022 harvest last fall, probably due to an extremely cold and wet spring/early summer; it rained almost nonstop until July 5th. This resulted in a late bloom and very few pollinators; only a couple dozen fruit resulted. This effected my other citrus adversely as well. About the only interesting thing on the tree were a couple of rather gnarly fruit, discussed on another thread. This could be caused by insect damage, or fungus. Here's the picture:
The three-lobed fruit only had two seeds, which I planted for kicks, hoping, perhaps for a weird looking plant. The single sprout was rather ordinary, however.
A large number of the upper branches are still thornless. It might be interesting to get some Dip-N-Grow and take some cuttings of said thornless branches and see if the thornlessness breed true.
