Title

Grain yield of wheat (Triticum aestivum L.) under long‐term heat stress is sink‐limited with stronger inhibition of kernel setting than grain filling

Birgit W. Hütsch; Dana Jahn; Sven Schubert Journal of Agronomy and Crop Science 2018. doi:10.1111/jac.12298

Other claims from this paper (15)

Intervention effect Heat stress decreased total above-ground biomass of wheat by 19% to 41%.
Intervention effect At grain filling, heat stress depressed wheat grain yield by 77%.
Intervention effect At maturity, heat stress depressed wheat grain yield by 58%.
Intervention effect Heat-stressed wheat had a significantly higher ear number per plant than the control.
Observation At maturity, the ear number per plant of heat-stressed wheat more than doubled.
Observation Heat stress strongly decreased kernel number per ear by 83% during grain filling.
Observation Heat stress strongly decreased kernel number per ear by 75% at maturity.
Observation Individual kernel weight of wheat decreased by 23% at maturity.
Intervention effect Heat-stressed wheat had a 36% lower harvest index than the control.
Observation Under heat stress, wheat water use efficiency for grain decreased by 62%.
Intervention effect Heat stress did not significantly change sucrose, glucose and fructose concentrations in ears and grains.
Intervention effect Heat stress reduced sink capacity in wheat, with smaller and fewer kernels than the control.
Mechanism The sink-limiting step during kernel set is probably active transport of hexoses into the developing kernels.
Observation The supply of assimilates to wheat kernels under heat stress was not restricted.
Mechanism Heat-stressed wheat presumably transpired more without higher total water consumption.
