While skeptical about the theory about rejuvenation of airlayers/clones as discussed off-topic at this other thread, i, too, wish that the theory is correct, since that would translate to eternal life of all clones of perennials(in the absence of disease/pests).
Now, and pardon my amateurish artistry, but on the illustration below, am really curious when the purported rejuvenation of the clone might actually occur. Does anyone here have the expertise to tell me which, and tell mewhy? Will subject A on sequence 1 already have self-conferred rejuvenation by having grown roots–but still attached to mother tree(B)?
Will subject A on sequence 2 now be considered younger than the mother tree(B)?
And on sequence 3, will removing the top of subject A and grafted back to B effectively result in A reverting to its original age? Or would it actually be ‘younger’ than the mother tree, by virtue of having been removed temporarily and grown on its own roots?
on to the next diagram, which between Y and Z will be rejuvenated?
