Obregonia denegrii f. variegata seedlings

[robinast]

I ordered some seeds of the Obregonia denegrii f. variegata from CactusHeaven in Malta. Have to graft the seedlings soon, some of them seem to be without any chlorophyll at all...

[fanecchissimo]

good luck. i wish they will be great!

Please show us some pictures of the graft !!!
I'm so curious !!!

Actually, nothing to show - the grafts are too small yet... But here you are:



The stock is Selenicereus, less tha 1 cm in diameter.

From ten seeds, I got 8 seedlings. Several were very weak and nearly colourless from the very beginning and so the grafting success was merely 50% - which actually is far too low for young seedlings: in general, the success is over 90%. All the grafts are on the Selenicereus hybr. stock

One of the seedlings is nearly without any chlorophyll:


and the others also seem to have some chlorophyll deficiency:


The previous plant from above:

The grafts are growing nicely - but in most plants, the variegation is only barely seen...





Only one graft has no chlorophyll at all, being completely yellow with some reddish hint here and there:

Very nice indeed! they show good progress.
How is your experience with selenicereus vs. pereskiopsis? Which one give the best results for you?

Well, the growth rate for the grafts on both stocks is nearly the same; on the Selenicereus at my conditions it may even be a bit higher. So far, I continue using both - but I easily may abandon the Pereskiopsis later. Or not...
