Persistence of photosynthetic components and photochemical efficiency in ears of water‐stressed wheat (Triticum aestivum)

Other claims from this paper (8)

Intervention effect Post-anthesis drought accelerated loss of chlorophyll, Rubisco and LHCII in flag leaves.
Intervention effect Drought affected photosynthetic component degradation less in awns and ear bracts than in flag leaves.
Intervention effect Water stress decreased PSII quantum yield in leaves.
Association Ear bracts had higher PSII quantum yield than leaves.
Intervention effect Removing grains immediately before measurement slightly reduced PSII quantum yield.
Association Even after grain removal, PSII quantum yield remained much higher in ear bracts than in flag leaves.
Mechanism The authors infer that grain-respired CO2 may help maintain high ear photochemical efficiency.
Mechanism The authors suggest stable ear photosynthetic components and high photochemical efficiency may sustain ear photosynthesis during grain filling under drought.
