Other claims from this paper (10)

Intervention effect Water deficit increased superoxide dismutase, peroxidase and catalase activities in maize leaves.
Intervention effect Water deficit increased polyphenol oxidase activity in maize leaves.
Intervention effect Foliar ascorbic acid reduced stress-induced antioxidant enzyme activities.
Intervention effect Ascorbic acid decreased proline in water-deficit-stressed maize.
Intervention effect Ascorbic acid decreased malondialdehyde in water-deficit-stressed maize.
Observation Ascorbate was oxidized to dehydroascorbate in maize leaves.
Observation Total ascorbate decreased in maize leaves.
Observation Dehydroascorbate increased in maize leaves.
Mechanism Ascorbic acid reduced harmful reactive oxygen species effects and improved water stress resistance.
Recommendation The authors suggested ascorbic acid treatment may improve stressed plants in arid and semi-arid regions.
