Other claims from this paper (11)
- Observation Stem hydraulic conductivity did not decrease significantly during the day.
- Observation Leaf relative water content decreased distinctly at midday versus predawn.
- Observation Leaf hydraulic conductance decreased distinctly at midday versus predawn.
- Association Diurnal leaf hydraulic-conductance loss accompanied a midday decline in stomatal conductance.
- Association Diurnal leaf hydraulic-conductance loss accompanied a midday decline in CO2 assimilation.
- Observation Positive root pressures were sufficient to refill leaf embolisms across habitats.
- Mechanism The authors concluded this bamboo does not use stem water storage for daily transpiration.
- Mechanism The authors concluded reduced leaf hydraulic and stomatal conductance protects the stem hydraulic pathway by slowing water loss.
- Observation Leaf hydraulic conductance did not recover in late afternoon.
- Mechanism The authors infer leaf embolism refilling probably depends fully on nocturnal root pressure.
- Mechanism Root-pressure embolism refilling could aid growth and persistence.
