Having trouble uploading images, this is a test run. Images are uploading to
ImageShack, but not appearing in this post. Any ideas?
thanks Ivica, haven't sorted it out yet, had to drag from one browser window to another to load this image url, but it worked.
This 45cm tall P.trifoliata has flowered and fruited 2 years in a row, after being noticed as an early flowering seedling amongst rootstock production seedlings. It is also fairly spindly, and probably would have been discarded as too thin for rootstock use.
If it turns out to be a consistent fruiter, it may defy the normal rules of Citrus development to reach flowering ?

Interesting.
Unusual flower too.

Very interesting indeed! How old was the seedling when it first flowered and produced fruit? |

Poncirus seedling first flowered between 2 and 3 years old. Looking at the foliage the plant doesn't seem strongly off type, compared to the rest of the rootstock seedlings, but it was obviously skinny and shorter than average. Probably the flower stood out as unusual and it seemed worth keeping as an early flowerer. |

Very interesting. Is it giving polyembryonic seedlings?

I saw no difference between seedlings during first 5 years. Unusual characteristics came later in this case: "When everything fits (poncirus)"

I have had a seedling poncirus for about 5 or 6 years that was planted one spring and fruited the following spring. It produces seedlings that do the same. The early fruiting tends to make it less desirable as a rootstock, but I have thought that it may make it useful in a breeding program.

Ned,
Are you sure the seedlings really reliably flower at one or two years old?
I have had a few early flowering Poncirus seedlings, and various research papers I have read recognise that these occur, but they all say that next generation seedlings revert to normal maturity time.
If you really do have consistent early maturity, then this does need using in some hybrid attempts. I'd love to have early flowering citranges etc.
