Other claims from this paper (13)
- Observation Final Amax of cucumber leaves was highest in MM-leaves.
- Observation Final Amax of cucumber leaves was lowest in LL-leaves.
- Observation Final Amax of cucumber leaves was intermediate in ML- and LM-leaves.
- Observation Acclimation of photosynthesis in cucumber leaves occurred within 7 days.
- Observation Full acclimation of thylakoid processes underlying PSII efficiency and non-photochemical quenching occurred in ML- and LM-leaves.
- Association Dark respiration of cucumber leaves correlated with irradiance level.
- Association Dark respiration of cucumber leaves was not correlated with Amax.
- Observation Light-limited quantum efficiency was similar in all cucumber leaves.
- Mechanism The increase in photosynthesis at moderate irradiance in LM-leaves was primarily driven by nitrogen import.
- Observation Nitrogen remained allocated in a similar ratio to Rubisco and bioenergetics in LM-leaves.
- Observation Allocation of nitrogen to light harvesting relatively decreased in LM-leaves.
- Association A contrary nitrogen response was associated with a decrease in photosynthesis in ML-leaves.
- Intervention effect Net assimilation of LM-leaves under moderate irradiance remained lower than that of MM-leaves.
