摘要：

The degree of moose damage was estimated for 32 Finnish pine progenies grown in two field trials in Central Finland. In both trials, the browsing intensity correlated negatively with the increasing geographical latitude of the progeny origin. The lower susceptibility of northern pine progenies to moose was associated with the higher dry matter content of current and 1-year-old needles of these progenies.
