Hi Loulac
I think SE is Standard Error - an expression of confidence in the result
SC is scion
RS is rootstock
I think the pdf is rather light on description though it's good to have some data. I agree that there are other factors to consider for a balanced assessment of quality. I noted that the trials used cleft grafting
I've just watched through a youtube video from a link posted earlier by aclum. (Thank you Anne!).
Cary Rivard seems like a knowledgeable helpful guy. He discusses amongst many other things plant spacings in high tunnels and in the field. He was talking of plant spacing 18 inches, 24 inches and 36 inches and had tabulated data for these. (Thats 45cm, 60cm, 90cm.)
Incidentally he pretty much dismisses every type of graft except tube grafts.
I'm interested in your interest! Are you planning on grafting next year? If so have you managed to source any rootstock seeds and grafting clips? Whereabouts in France are you?
In the UK I can only find Aegis and HeMan rootstocks and spring loaded grafting clips. If you know of sources of others, especially silicone clips do let me know.
Thanks, Jeremy
