e0“A greenhouse experiment was conducted to evaluate the effects of water stress on leaf water potential, plant growth, and photosynthesis in purple passionflower ( Passiflora incarnata )”
e2“Plants in both 25% and 10% ET irrigation treatments had reduced net CO 2 assimilation rates (4.25 and 3.50 μmol·m −2 ·s −1 , respectively) than plants watered with 100% ET (8.53 and 6.77 μmol·m −2 ·s −1 , respectively)”

Other claims from this paper (6)
- Intervention effect The 10% ET irrigation lowered leaf water potential compared with control plants in Passiflora incarnata.
- Intervention effect The 10% ET irrigation decreased the maximum carboxylation rate allowed by rubisco by about 60%.
- Intervention effect The 10% ET irrigation reduced the rate of photosynthetic electron transport by about 30% compared with control.
- Intervention effect The 10% ET irrigation reduced triose phosphate use (TPU) by about 45% compared with control.
- Intervention effect After recovery, previously stressed plants showed no difference from control in water potential and net CO2 assimilation rates.
- Recommendation Passiflora incarnata plants could adapt well to landscaping situations where extreme drought is expected.
