An unusual seedling

[BorisR]

An unusual Keraji seedling. The bud is not visible. I wonder what he's going to do next. Will he die?

Looks funny, keep us updated

cool looks like a carnivorous pitcher plant

umbrella tree.

I grafted a variegated macrophylla and it turned completely albino in 4 months.

Boris,
Is this a cotyledon?

[BorisR]

Boris,
Is this a cotyledon?

Cotyledons, aren't these the parts from which the seed is formed? They remained at ground level, as usual. This leaf appeared in the place where the first two real leaves usually appear, located opposite each other.

[Ilya11]

But cotyledons, they are normal?
  So only  the first two leaves are fused together. Interesting, what will happen to the second pair.

[BorisR]

Yes, the cotyledons are normal. I have not found a bud. So I assume that the plant will die over time. Or, after some time, it will be able to form a bud.

[BorisR]

Perhaps it is a hybrid with PT, and the three-leaf genes somehow did not work correctly.

[Till]

Let's wait. I had seedlings that lost the central bud. It took a very very long time until it the top of the stem burst and a new bud appeared.

[Marcin]

There should be dormant buds in the axils of cotyledons. A new twig can grow from there, as in the photo.

Have you found evident hybrids with Poncirus?

Yes, I've had this happen on PT seedlings and hybrid seedlings: the top died and then the bud below woke up. But the fact is that this seedling does not have sinuses. This funnel-shaped leaf is the first one, and there are no leaves or buds below it. I also did not find a bud in the center of the funnel. Maybe it will still form? I had the idea to injure the stem under the leaf to form a callus, which would then form a bud. But I wonder if the plant can handle itself.

Yes, there are hybrids. I wanted to write about this later, when all the seeds have germinated, and the percentage of hybrids obtained will be clear. So far, I can say that there are about 20 Keraja × PT hybrids. There is also Valentine × PT, PT × Valentine and some others, the seeds are still sprouting.

[Marcin]

I meant the area described in your picture as cotyledonary node, I think there is a hidden bud above each cotyledon. Or at least a bud can form there. A few times I've seen a new twig appear in the axil of the cotyledon, when the seedling had no other buds left.

This could work. Or if there's no growth for a longer time, you could cut off the "funnel" and maybe a bud will appear at the top, such as Till wrote.

Cool, that's good news. Keraji x P.t. is prospective I think, it should be very hardy.
