Phellogen initiation in the stems of Eucalyptus camaldulensis Dehnh

Abstract

The induction of phellogen in E. camaldulensis stems by various environmental factors was investigated.

High humidity and a continuous flush of oxygen were found to cause early initiation of the phellogen. Light, temperature changes, or mechanical pressure did not play an important role in the initiation of phellogen as long as they were applied under dry conditions.
