Red oak is a ring porous, intermediately shade tolerant, and moderately fast growing tree species that is native to most of the eastern United States. Red oak trees can live to be more than 300 years old and vessels in red oak can be as long as 10 meters.
This is a 3D representation of about 1,000 X-ray microCT scans of a red oak (Quercus rubra) petiole. The grayscale images below show transverse and longitudinal views through the scanned petiole. White areas in the images generally represent cell walls and other dense materials that absorb X-rays. The dark gray areas are typically air spaces.
The original microCT data were collected at the Lawrence Berkeley National Laboratory Advanced Light Source (beamline 8.3.2, microct.lbl.gov).
