Other claims from this paper (9)
- Intervention effect Waterlogging caused leaf yellowing and senescence.
- Intervention effect Waterlogging decreased leaf area, dry matter and leaf relative water and chlorophyll contents.
- Intervention effect Waterlogging decreased membrane stability in roots and leaves.
- Association These waterlogging-associated declines were greater in Pusa 207 than in ICP 301.
- Intervention effect Superoxide radical, hydrogen peroxide and TBARS contents initially decreased during waterlogging.
- Intervention effect Superoxide dismutase, ascorbate peroxidase, glutathione reductase and catalase increased under waterlogging.
- Association ICP 301 had greater antioxidant enzyme activity and less oxidative stress than Pusa 207.
- Mechanism Greater antioxidant activity and reduced oxidative stress may explain the greater flooding tolerance of ICP 301 relative to Pusa 207.
- Mechanism The authors attribute waterlogging-induced ROS increase to NADPH oxidase.
