Other claims from this paper (10)

Intervention effect Waterlogging at the jointing stage caused the second-largest yield penalty, after the tillering stage.
Observation Waterlogging at the grain filling stage had less effect on yield.
Intervention effect Waterlogging at the tillering stage reduced spike and grain numbers per m2.
Intervention effect Waterlogging at the jointing and booting stages reduced grain weight through reduced dry matter translocation.
Intervention effect Waterlogging at the tillering stage significantly reduced chlorophyll content.
Intervention effect Waterlogging at the tillering stage lowered Fv/Fm, apparent electron transport rate and effective quantum yield of photosystem II.
Intervention effect Waterlogging at the tillering stage lowered photochemical quenching (qP).
Intervention effect Waterlogging at the grain filling stage improved leaf photosynthetic capacity and grain yield.
Observation The tillering stage was the most susceptible growth stage of wheat to waterlogging.
Recommendation The authors suggest that maintaining photosynthetic performance after anthesis could be a strategy for increasing wheat grain yield.
