Graft transmissibility influenced by the
tissue used for inoculum. As different tissue
from the same diseased budwood were
used as inoculum, the transmissibility is
different as follows: single bud bud, , 22/26 (85%);
piece of stem without bud bud, bud bud, , 29/43 (67%);
piece of stem bark bark,2/43 ,2/43 (5%).
Above data indicated that the graft
transmissibility by bark as inoculum is much
lower than that by the other tissues (Zhao et al.
1982).
