Title

Differential responses of maize yield to drought at vegetative and reproductive stages

MI Na; Fu CAI; Yushu ZHANG; et al. Plant Soil and Environment 2018. doi:10.17221/141/2018-pse

Other claims from this paper (6)

Intervention effect Progressive drought significantly reduced maize grain yield during either the vegetative or the reproductive stage.
Intervention effect Reproductive-stage progressive drought reduced grain yield by 41.6-46.6%.
Intervention effect Vegetative-stage progressive drought reduced grain yield by 18.6-26.2%.
Intervention effect The grain yield reduction from reproductive-stage drought was greater than that from vegetative-stage drought.
Mechanism The decrease in kernels per ear largely caused the decrease in maize grain yield.
Recommendation Guaranteeing water supply for maize during the reproductive stage is crucially important to avoid yield loss.

Tomasz Hura; Katarzyna Hura; Agnieszka Ostrowska; et al. Plant and Soil 2015. doi:10.1007/s11104-015-2607-1

Other claims from this paper (9)

Intervention effect Rehydration further increased hydrogen peroxide in the cultivar that did not fully recover.
Intervention effect Rehydration inhibited photosynthetic apparatus activity compared with drought in that cultivar.
Observation On day 42 of rehydration, flag leaf photosynthetic activity was reduced.
Intervention effect Rapid rehydration lowered total peroxidase activity in its first week.
Intervention effect Rapid rehydration lowered catalase activity in its first week.
Observation Gradual restoration of leaf water content compensated increased hydrogen peroxide.
Observation Gradual leaf water restoration prevented further decline in photosynthetic apparatus activity.
Mechanism Rapid rehydration intensified physiological processes associated with reactive oxygen species overproduction.
Mechanism The authors suggest electron leakage from an overloaded electron transport chain causes hydrogen peroxide overproduction.
