In an inoculation experiment to test the effect of wood moisture content on infection of Sitka spruce ( Picea sitchensis ) stumps by basidiospores of Heterobasidion annosum , exposure to high rainfall increased infection in the heartwood and reduced sapwood infection compared to covered stumps. This was associated with a greater moisture content in both wood types. Within‐treatment variation in the amount of infection was high and it is suggested that endogenous factors in stumps may have a greater influence on infection than the environment or the availability of spores.
