Commercial grafting!

[XP_2600]

I wonder how the commercial production for grafted cactus going on ? (the most famous ones are the Gymnocalycium mihanovichii on heliocereus)
I find the stock looks fresh and young, while the scion looks old enough and attached well, do they let the stock root then graft? or take cuttings, graft them and let they root ?

I would think they do both at the same time, as it makes for faster production.

I think they root the Hylocereus stocks first, as the take rate using non-rooted specimens may be low. The stocks look fresh and young as they are normally grown inside tunnelhouses/greenhouses and given a lot of fertilizer and water. They have specialized techniques on how to use Hylocereus as stock, you can glean some information from this site:

I've seen the "Lollipop" type coloured Gymocalyciums grafted to unrooted Hylocereus which they sell in bundles from China via alibaba or other wholesale website
