The influence of Ceratocystis polonica inoculation and methyl jasmonate application on terpene chemistry of Norway spruce, Picea abies

Constitutive and inducible terpene production is involved in conifer resistance against bark beetle and their associate fungi. We investigated terpene induction 30 days and one year after Ceratocystis polonica inoculation and methyl jasmonate application and demonstrated effects of terpene chemistry on spruce resistance against the spruce bark beetle, Ips typographus.
