- 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.
