Other claims from this paper (6)

Intervention effect Drought lowered photosynthetic rate and chlorophyll content; both recovered after watering.
Intervention effect In fully pollinated maize, drought significantly reduced apical kernel dry weight at 12–16 days after pollination.
Intervention effect In fully pollinated maize, drought significantly reduced apical kernel volume at 16 days after pollination.
Intervention effect Drought significantly reduced mature apical kernel dry weight and volume.
Intervention effect Apical kernels grew normally under drought when basal ear positions were not pollinated.
Mechanism The authors attribute apical kernel failure under drought to reduced assimilate production and supply.
