As I have quite a lot of seedlings of the three-ribbed 'Onzuka', I just decided to play with them a bit. So I grafted the seedlings onto different rootstocks this morning (6...8 seedlings in each combination):
- Opuntia humifusa - seedlings
- Cuttings of the seedlings of O. humifusa
- Two different clones of O. humifusa - unrooted pads
- Two different clones of O. fragilis - unrooted pads
- O. basilaris - unrooted pads
- Echinopsis denudata - seedlings
- Selenicereus hybr. - rooted cuttings
- Selenicereus pteranthus - unrooted cuttings
- Pereskiopsis spathulata - intensly growing plants from the previous year
Time will show what will happen and on which stocks the growth is good enough.
Some pictures taken shortly after I had finished with grafting:

Very interesting project! Keep us updated.

I'm trying, I'm trying... :)
I am too busy now for making pictures and counting succsessful / unsuccsessful grafts. Nevertheless, I made some photos of the young Onzuka tricostatums and also of some grafts made at the same time. Have a look:

Great work.
How did the opuntia grafts work out? I often have problems with humidity and large cut-surfaces, because they get infected with fungi. Do you also have this problem?

Well, actually not - not at all. Using
Opuntia as a rootstock is quite a new thing for me and I do not have just much experience yet. But so far I have not lost ANY (out of around 50)
Opuntia grafts due to the rot of the stock. Some grafts just did not take, right - but none of the cut surfaces were damaged by fungi (though I keep the grafted plants in very humid (close to 100%) environment for a week or so.
I plan to take some more photos next week and also calculate the succsess rate. So far I can say that
O. basilaris and
Epiphyllum as rootstocks did show very poor results...
Last month ago I made around 30 grafts on Echinopsis and 60 on Opuntia. On Echinopsis I had fungi problems in around 50% of the plants (I had to use copper to stop the infection) and on Opuntia I had no problems, even if the cut surface was much larger. In both cases I used the same blades, the same sterilizing products (ethanole and H2O2).

Overview of grafted Onzuka tricostatum seedlings on different rootstocks (rootstock - total grafts/success/not sure yet):
- Opuntia humifusa seedlings - 7/7
- Cuttings of the seedlings of O. humifusa - 7/6
- Two different clones of O. humifusa, unrooted pads - 7/7
- O. fragilis v denudata, unrooted pads - 7/7
- O. fragilis v parviconspicua, unrooted pads - 7/2
- O. basilaris, unrooted pads - 7/0
- Echinopsis denudata seedlings - 7/5/2
- Selenicereus hybr., rooted cuttings - 8/7
- Selenicereus pteranthus, unrooted cuttings - 6/5
- Pereskiopsis spathulata, intensly growing plants from the previous year - 8/7
- Epiphyllum, young intensly growing plant - 7/2
As you may easily guess, grafts on
Pereskiopsis have the most vigorous growth. And so far, there is no big difference in growth rates on the other rootstocks.
Some pictures:

None of the grafts with O. basilaris was successful. It seems to me that this rootstocks is not suitable for Astrophytums (I tried it last also year - with the same result).

I do like this graft on the
Echinopsis denudata!
(https://www.e-aiand.com/kaktusefoorumisse/fragdenud.JPG)
Grafts on the
Opuntia fragilis v denudata took very well...
(https://www.e-aiand.com/kaktusefoorumisse/fragparv.JPG)
but results with the
O. fragilis v parviconspicua were poor... True enough, it's too early to make any conclusions as the number of grafts is too low.
(https://www.e-aiand.com/kaktusefoorumisse/humis.JPG)
O. humifusa seems to fit well for using as an Astrophytum rootstocks -both as seedlings...
(https://www.e-aiand.com/kaktusefoorumisse/humisu.JPG)
...and as unrooted pads.
(https://www.e-aiand.com/kaktusefoorumisse/peresk1.JPG) (https://www.e-aiand.com/kaktusefoorumisse/peresk3.JPG)
Pereskiopsis, of course, is probably the best choice for the youngest seedlings.

Very nice work!
I'm impressed with the growth of the kikko koh-yo. They seem to have started growing very fast already.
Great job, congratulations!

Yes, you're right - somehow, they seem to be in hurry indeed. :)
By now, the young Onzukas have grown quite a bit. Here, the initial observations of
Astrophytum myriostigma f. tricostatum 'Onzuka' grafts on several rootstocks:
- not noticeable difference between Selenicereus hybr and Pereskiopsis in growth rates; or maybe, grafts on Selenicereus hybr grow a little bit faster
- growth rate on the Selenicereus pteranthus is a little bit lower than in case of the above-mentioned rootstocks
- grafts on Echinopsis stock grow more slowly
- grafts on Opuntia humifusa also grow slowly; nevertheless, their growth rate is higher than that of the ownrooted seedlings
- I did not notice a big difference in growth rates while comparing grafts on unrooted pads and grafts on growing seedlings
- Opuntia fragilis does not seem to be suitable for A. myriostigma: though the grafts generally took, their growth rate is even lower than that in case of own-rooted seedlings
It is too early to calculate the percentage of the three-ribbed seedlings as the rib number has not stabilized yet. Some grafts that initially seemed to have 4 ribs, are now losing the fourth one and some three-ribbed grafts have started to form the additional rib(s). Also, in some cases, it's not clear how many ribs there are.
Have a look at some photos (most of the grafts are around 15...20 mm in diameter and 20...25 mm in height now):

Hi robinast,
Your little onzuka are very very nice, congratulation. ;)
they are your own plants seeds?
Thank you, ibiza23!
Yes, the seeds were my own.
ok good,
Do you have photos of mother plants?

Ah very nice!! I like I like ::) ::) ::)
Yeah, indeed - beauties they are! :D
those motherplants are great! and seedlings are very promising too!!!
