- Intervention effect Flooding induced abnormal xylem.
- Intervention effect Tilting induced abnormal xylem.
- Intervention effect Flooding decreased dry weight increment in roots and needles.
- Intervention effect Flooding increased bark growth.
- Intervention effect Tilting did not decrease root and needle dry weight increment or increase bark growth.
- Intervention effect Tilting decreased height growth.
- Intervention effect Tilting stimulated tracheid production.
- Intervention effect Tilting formed well-developed compression wood with rounded, thick-walled, lignin-rich tracheids lacking S3.
- Intervention effect Flooded seedlings had thicker bark.
- Intervention effect Ethrel-treated seedlings had thicker bark.
- Intervention effect Flooding increased stem ethylene.
- Intervention effect Flooding formed rounded, thick-walled tracheids lacking key compression wood features.
- Intervention effect Ethrel greatly increased stem ethylene in vertical stems.
- Intervention effect Ethrel on vertical stems did not induce well-developed compression wood.
- Intervention effect Ethrel treatment reduced underside tracheid lignification in tilted stems.
- Intervention effect Ethrel induced longitudinal resin ducts in xylem.
- Mechanism Ethylene appeared less important in compression wood formation than bark growth.
