Pre-treatment with salicylic acid induces phenolic responses of Norway spruce (Picea abies) bark to bark beetle (Ips typographus) attack

摘要

The temporal gradations of the investigated phenolics in Norway spruce bark after bark beetle (Ips typographus) attack followed the general eco-physiological concept. Treatment with salicylic acid inhibits bark beetle colonisation, alleviates the phenolic responses and activates the synthesis of condensed tannins on later sampling dates.
