Other claims from this paper (10)
- Intervention effect Water stress significantly decreased net CO2 assimilation and leaf stomatal conductance.
- Intervention effect Water stress did not affect PS II photochemistry in dark-adapted leaves.
- Intervention effect Maximal PS II efficiency did not change significantly.
- Observation No apparent damage occurred in PS II reaction centre or antenna systems.
- Intervention effect Water stress decreased excitation capture efficiency and PS II electron transport quantum yield.
- Intervention effect Water stress significantly increased non-photochemical quenching.
- Intervention effect Water stress increased susceptibility to photoinhibition.
- Association Photoinhibition became more pronounced with increasing water stress.
- Intervention effect Water-stressed plants had a smaller rise in non-photochemical quenching during photoinhibition.
- Mechanism The altered PS II responses might explain increased susceptibility to photoinhibition.
