Other claims from this paper (10)
- Intervention effect Leaf water potential, stomatal conductance, transpiration and net photosynthesis decreased quadratically as flooding duration increased.
- Intervention effect One day of flooding reduced net photosynthesis by 17% relative to controls.
- Intervention effect Seven days of flooding brought net photosynthesis near zero.
- Association After one day of flooding, reduced photosynthesis was not associated with leaf water potential or stomatal conductance.
- Association Recovery of leaf water potential, transpiration and photosynthesis after a week was linear with prior flooding duration.
- Association Recovery of stomatal conductance after a week followed a quadratic relation with prior flooding duration.
- Intervention effect Flooded plants had not regained control-level gas exchange after seven days of recovery.
- Association Stem dry weight had a linear relation with flooding duration.
- Association Root and leaf dry weight had quadratic relations with days of flooding.
- Intervention effect Even one day of flooding decreased plant dry weight, with greater decreases over longer flooding.
