| Résumé : | The phloem phenolic content of 5 Scots pine clones was analysed in the branches of 3 trees per clone. Five emerging beetles were encaged in one branch per tree and the damage were estimated 2 weeks later by measuring the area of removed bark. Phloem phenol content was analysed in another branch of the same trees. Clones were clearly separated from each other by their phenol content, but not by weevil damage. However, a significant negative correlation was found between the concentration of an acetophenone glycoside and weevil damage. |
