Other claims from this paper (8)
- Intervention effect Eight days of waterlogging reduced wheat shoot and root growth through maturity.
- Intervention effect Hypoxic seedlings had 27% higher root carbon dioxide emission rates.
- Intervention effect Hypoxic seedlings had 37% higher root oxygen consumption rates.
- Mechanism Whole-root elevated respiration disappeared during aerated recovery with newly initiated roots.
- Observation Previously hypoxic roots retained abnormally high respiration rates.
- Intervention effect Hypoxic roots had 3.6 times higher total sugar concentrations than untreated roots.
- Mechanism Elevated sugar may explain persistent high respiration.
- Observation Exposed roots failed to regain weight after waterlogging or hypoxia.
