| Research Abstract |
Cavitation development in pine wilt disease was monitored non-destructively by MRI after inoculation of pine wood nematodes. The massed embolism occurred around the nematode inoculation point, and it developed gradually. Patchy embolisms around xylem resin canals also occurred independently from the massed embolism. The patchy embolisms were thought to be induced by migrating nematodes in the resin canals.
