Hi all,
Just an addition as I found a very interesting report on multiplication of Sorbus domestica, including best grafting technics and best rooting technics.
It's in French but most online translator should allow you to get the interesting parts out of it if you are not french speaker:
https://hal.science/hal-03565204/document
"Comment domestiquer le Cormier (Sorbus domestica)? Bilan des recherches sur la multiplication sexuée et végétative."
BTW, I successfully grafted Sorbus domestica scions on Pyrus communis rootstock this year based on ancient book mentioning it as possible. So far so good.
Kind regards
