The resistance of dahurian larch (Larix dahurica) to fungal attack by
Postia placenta and Trametes versicolor was evaluated in laboratory so
il-block tests. Average weight losses ranged from 13.7 to 34.5 percent
with P. placenta and 9.6 to 34.9 percent with T. versicolor. These re
sults suggest that dahurian larch should be considered non-durable in
terms of resistance to fungal attack.
