e0“The goal of this study was to identify water‐stress‐related limitations in the antioxidant protection in cotton ( Gossypium hirsutum L.) in the field”
e1“Cotton was grown under full irrigation and severe‐to‐moderate water deficits in both years of the study”
e4“Gluthione reductase activity varied (≈ 5×) seasonally, but again not in response to water deficits”

Other claims from this paper (7)
- Intervention effect Glutathione amount did not respond to the water treatment in field cotton.
- Observation Glutathione amount varied more than twofold during the sampling interval.
- Intervention effect The reduced/oxidized glutathione ratio varied seasonally but did not respond to water deficits.
- Intervention effect Ascorbate amount increased under water stress, by about fivefold.
- Intervention effect Ascorbate peroxidase activity increased under water stress, by about 1.5-fold.
- Intervention effect Malondialdehyde amount varied seasonally by about twofold and did not respond to water stress.
- Mechanism Antioxidant metabolism under production-condition water deficits was sufficient to protect cotton against oxidative damage.
