Scots pine trees (Pinus sylvestris) recovering from a 90-100% defoliation 2-3 years previously were pretreated with small mechanical wounds or inoculations with the blue-stain fungi Leptographium wingfieldii and Ophiostoma canum. Pretreated trees were less susceptible to a subsequent massive inoculation with L. wingfieldii than untreated control trees, which were extensively colonised by the mass-inoculation. A low pretreatment dosage of L. wingfieldii was somewhat more effective in inducing disease resistance than a higher dosage. Pretreatment with L. wingfieldii, O. canum, and mechanical wounding were about equally effective inducers of resistance in Scots pine, even though L. wingfieldii is known to produce much more extensive phloem necrosis than the other pretreatments. Thus, the strength of the induced resistance response did not depend on the amount of host tissues that was destroyed by the pretreatment. Previously, induced disease resistance has been demonstrated in Norway spruce (Picea abies), and the present study shows that similar responses can be activated in Scots pine.
