摘要:
The role of the resin‐top disease caused byPeridermium piniin volume and value losses to Scots pine (Pinus sylvestrisL.) was surveyed in two heavily infected stands in northern Finland. Of the Scots pines, 26% were infected by the disease.Peridermium pinicaused 2% volume losses to saw timber trees and 3% volume losses to pulpwood trees in the stem‐lesion class and 10% and 14% in the dead‐top class, respectively. The disease caused saw timber volume losses to saw timber trees of 34% and 22% in the stem‐lesion and dead‐top class, respectively. However, saw timber volume losses increased the pulpwood volume in both disease classes. The disease reduced the marketing value of saw timber trees and pulpwood trees by 18% and 3% in the stem‐lesion class and by 15% and 14% in the dead‐top class.
