Resin oozing from wood. Cross-section of a trunk of the larch tree (Larix eurolepis) showing the circular bands of growth rings,each ring representing a year of growth for the tree. Resin is being exuded from the cut end. This is produced within resin ducts and is thought to serve as a deterrent to wood-boring beetles and as a defence against rot fungi | |
