Significance of wood terpenoids in the resistance of Scots pine provenances against the old house borer, Hylotrupes bajulus , and brown rot fungus, Coniophora puteana
We tested how terpenoid (i.e., monoterpenes and resin acids) composition and concentration in wood affects resistance against wood-borers and decaying fungi. Scots pine ( Pinus sylvestris ) wood from nine provenances having variable terpenoid profiles was studied against the old house borer, Hylotru...
