i needed to shorten some of my apple rootstocks(B9 and M26) to fit in the pots i have for them so i took a chunk off the bottoms that carried some roots. i put them in cups with the same mix the stocks were going into at about ~1" depth. not a typical root cutting. a super root cutting! well see how it goes.
Last spring I took about 4 of my Bud 9 tops left over from my grafting and put them in a quart jar of water a placed in the window sill. It took over a month, but 2 of them rooted.
since ohxf stock is propagated by cuttings and the roots are mainly at the bottom of the stock i didnt have extra to cut off. i did have a couple quince cutoffs to park some medlar on. not my best work but well see:
