Title

Other claims from this paper (9)
- Intervention effect Net photosynthesis dropped 94% during drought.
- Intervention effect Conductance dropped 95% during drought.
- Intervention effect SIF values decreased 21% during drought.
- Intervention effect Electron transport rate fell 64% against control in the last drought week.
- Observation Electron transport continued as net photosynthesis approached zero.
- Association SIF yield correlated positively with steady-state fluorescence.
- Observation Normalized steady-state fluorescence and SIF yield had a more pronounced drought response.
- Method / resource The authors infer that SIF may be a less accurate photosynthesis estimator in brief mild stress.
- Mechanism The authors suggest light reactions mainly control SIF on a different timescale from stomatal response.
