- Intervention effect P60 significantly improved all tested indices relative to P22.
- Intervention effect Higher planting density decreased specific leaf area.
- Intervention effect Higher planting density increased nitrogen balance index.
- Observation Dry to fresh weight ratio and photochemical reflectance index were significantly affected without a general tendency.
- Intervention effect Light penetration did not affect photochemical reflectance index.
- Observation Nitrogen balance index decreased significantly in the upper canopy.
- Intervention effect Less crown light increased specific leaf area and photochemical reflectance index.
