Article Figures & Data
Figures
- Fig. 1.
Dissection of noninjected tree that died from Dutch elm disease. The sapwood was clear. Discoloration associated with the disease was in the tissues between the wood and bark.
- Fig. 2.
The discolored wood associated with the four USFS injection wounds in this tree was well compartmentalized within the tissues present at the time of injection.
- Fig. 3.
The discolored wood associated with the four USFS injection wounds in this tree was throughout almost the entire cylinder of wood present at the time of injection.
- Fig. 4.
Obvious decay associated with a USFS injection wound.
- Fig. 5.
Discoloration associated with gravity-flow injections repeated for 3 consecutive years.
- Fig. 6.
Discoloration 8 feet above injection wounds made in 4 consecutive years by the deep drill-hole method with pressure.
- Fig. 7.
Discoloration associated with wounds from deep drill-hole pressure injections followed the next year by the USFS shallow-hole pressure injection.
- Fig. 8.
Dark discoloration associated with deep drill-hole injections made for 2 consecutive years.
- Fig. 9.
The discolored wood associated with injection wounds made on the flat side of the tree coalesced, while those made on the ridges of large roots did not.
- Fig. 10.
Very slight injury was associated with shallow injection wounds Inflicted in 1 year, especially when the sapwood was wide.
- Fig. 11.
The discolored areas associated with the drill wounds in this tree spread into a wedge shape when they touched the large central core.
- Fig. 12.
The injection wounds that touched the internal decay spread rapidly to form large columns. The wounds that were surrounded by clear sapwood were well compartmentalized.
