Abstract
The susceptibility of Scots pine (Pinus sylvestris L.) sap- and heartwood against the wood decaying brown-rot fungus (Coniophora puteana)
was investigated after long-term forest fertilization at three
different sites in central Finland. Different wood properties: wood
extractives, wood chemistry, and wood anatomy were used to explain sap-
and heartwood decay. Scots pine sapwood was more susceptible to decay
than its heartwood. In one site, sapwood seemed to be more resistant to
wood decay after forest fertilization whereas the susceptibility of
heartwood increased. Significant changes in the sapwood chemistry were
found between treatment and sites, however, no relationship between wood
chemistry and wood decay was observed in the factor analysis. The
results of this study show that there was an inconsistent relationship
between decay susceptibility and fertilization and the measured physical
and chemical attributes of the wood were not consistently correlated
with the decay rate.
