Other claims from this paper (7)
- Intervention effect Water deficit and flooding stress decreased rice photosynthetic capacity (Vcmax25) and water transport capacity (Kmax) during the post-stress period.
- Intervention effect Water deficit and flooding stress increased rice intrinsic water-use efficiency (iWUE) by altering the relation between photosynthetic rate and stomatal conductance.
- Association The stress-induced decrease in Vcmax25 was significantly correlated with the decline in Kmax in rice.
- Association The Vcmax25-Kmax relationship differed significantly between the water deficit and flooding treatments.
- Observation In rice under flooding, the slope of the Vcmax25-Kmax relationship is closer to 1:1.
- Intervention effect Model predicts that stress-induced disproportionate Vcmax25-Kmax co-reduction improves rice iWUE.
- Intervention effect Model predicts that the same Vcmax25-Kmax co-reduction keeps the intercellular to atmosphere CO2 concentration ratio relatively high in rice.
