Other claims from this paper (12)
- Intervention effect Leaf water potential of drought-stressed potato cultivars decreased from the first day of treatment.
- Observation Diacol Capiro leaf water potential reached about -2.00 MPa at 4 days after treatment.
- Observation Pastusa Suprema leaf water potential reached about -2.00 MPa at 5 days after treatment.
- Observation Esmeralda leaf water potential reached about -2.00 MPa at 6 days after treatment.
- Intervention effect Drought-stressed cultivars showed decreased A, gs and E from the first day after treatment.
- Association Leaf temperature was highest when stomatal conductance was lowest in the three drought-stressed cultivars.
- Association WUEi was higher in Esmeralda under drought.
- Association WUEi was lower in Diacol Capiro (DC) under drought.
- Observation PSII photochemical efficiency (Fv/Fm) stayed above 0.8 in all drought-stressed cultivars, suggesting no non-stomatal limitation of photosynthesis.
- Intervention effect Chlorophyll content of Esmeralda increased under drought from 5 to 7 days after treatment compared with well-watered plants.
- Intervention effect Carotenoid content, Car/Chl ratio and electrolyte leakage increased in the three drought-stressed cultivars.
- Mechanism Early synthesis of carotenoids may maintain photosystem II function under water stress.
