Other claims from this paper (9)
- Observation Photosynthesis was optimal at 0.5 mol m−3 Pi.
- Observation Light utilization capacity was highest at 0.5 mol m−3 Pi.
- Observation Leaf organic phosphorus content was maximal at the optimal photosynthesis phosphate concentration.
- Intervention effect Low medium phosphate inhibited plant growth rate.
- Intervention effect Phosphate deficiency decreased photosynthetic oxygen evolution.
- Intervention effect Phosphate deficiency decreased PSII photochemistry efficiency.
- Intervention effect Phosphate deficiency decreased PSII electron transport quantum efficiency.
- Observation PSII primary electron acceptor QA was highly oxidized at 0.1 mol m−3 Pi.
- Mechanism Reduced RuBP regeneration efficiency mainly caused diminished photosynthesis under sub and supra optimal Pi at high light.
