- Abstract:
- A sample of Fagus grandifolia that had survived extensive damage was studied. Ring counts indicate that the tree had been knocked over after 10 years of growth. A 2 year old branch subsequently dedifferentiated into a trunk that 10 years later was 20 feet high and normal looking. A 6 to 7 year old branch at the time of injury remained a branch 10 years later, indicating a potential cap on dedifferentiation. Microscopic analysis of cells from the juncture of the new and old trunk showed evidence of dicotyledonous tension wood, confirming that Fagus grandifolia is capable of generating tension wood to manipulate the orientation of branches and trunks.
