some experimental grafts
Pterocactus tuberosus 4" pot 6 month old graft on Pereskiopsis this started with a 1" section.
And on Opuntia subulata monstrose 4 month old I find it interesting
how the scion has taken on the "branching" characteristics of the stock

I agree. This must be so. Very cool Bob! I think you discovered a new chimera!peterb wrote:I'd venture the second graft is a chimera, incorporating tissues from the subulata into the tuberosus, accounting for the monstrose appearance of the scion. Very unusual and interesting!

I have 3 of these grafts on the Opuntia stock
and all are branching quite well.
Much more than the ones grafted on the Pereskiopsis
stock,so it could be a chimera type thing going on.
I wonder what would happen grafting to O. subulata
crest probably nothing but I will give it a shot.
I should name it before someone else does,how about this
genus name +Pteropuntia
cultivar name +Pteropuntia cv.Patten
or
cultivar name +Pteropuntia cv.Cactusbutt
and all are branching quite well.

This is a very interesting issue, although I don't think it's a chimera. It's quite unlikely that the opuntia cells have traveled throughout the scion tissues (that would mean that these cells can detach and travel like a malignant tumor through the scion. Even more, manage to spread/diffuse evenly over the whole scion. As far as I understood, chimera cacti form when at the border stock/scion tissue gets mixed and forms a new growth from that point. And even then, these tend to be unstable and easily revert back to unmixed tissues.
But, nevertheless, it is very fascinating.
There are two more possibilities that can explain this phenotype:
1. A virus that causes the monstrose in the opuntia, and that has infected the scion. In that case, the growth should remain this when you degraft. You should in this case be able to provoke monstrose formation by transplanting only a small piece of tissue to other cacti.
2. It consider it also likely that the monstrose formation in this opuntia is due to hormonal abnormalities. In that case, the scion sprouts due to this altered hormone levels. I would also feel safer if this turns out to be the cause, as I would not be too keen on virus-induced malformation...
Well, that's my two cents on this topic. I must admit, I'm quite new to cacti. But as geneticist, I'm very much interested in this!
I' think I'll experiment with this as well. There is a lot to discover about stock-scion effects...
