Changes in toughness and fracture characteristics of wood attacked by the blue stain fungus lasiodiplodia theobromae

摘要

Losses in toughness correlated with losses in weight were found in birch (Betula verruscosa), Scots pine (Pinus sylvestris) and Caribbean pine (Pinus caribaea var. Hondurensis) over a six months period after inoculation with the blue stain fungus Lasiodiplodia theobromae. Differences between wood samples loaded radially and tangentially in the toughness testing device were not found, probably because the size of the samples (10x10x100 mm) was smaller than that specified in standards.
