Absorption d'un panneau de signalisation par un platane à Noves (13). La croissance radiale des arbres est assurée par le cambium, une couche de cellules mère en perpétuelle division. Lorsque nécessaire, le cambium peut produire un cal pouvant totalement englober un corps étranger pour poursuivre ensuite normalement sa croissance.
