Hello Jerry,
It would be neat to try the method you mention in
tissue culture using meristems instead of whole buds. A grad student at
the university of MD tried to obtain graft induced chimeras in the early 90's by
using in vitro techniques. She was trying to produce a "hand in glove"
type apple chimera which would have the outer cell layer from a scab resistant
apple variety and the inner cell layers from a high quality apple susceptible to
scab. She was also trying to produce a thornfree blackberry hybrid in the
same way. There are thornfree Rubus which are natural hand in glove type
chimeras and need to be propagated by stem cuttings rather than root cuttings in
order to maintain thornlessness.
