Other claims from this paper (9)
- Observation During the first 24 hours of chilling, stomata remained open and plants wilted as transpiration exceeded root absorption.
- Observation ABA did not accumulate in bean leaves or roots during the first chilling phase.
- Observation After 24 hours of chilling, ABA increased in roots and leaves.
- Observation After 24 hours, leaf diffusion resistance increased.
- Observation Turgor recovery was not associated with osmotic adjustment.
- Observation After turgor recovery, stomata remained closed and root and leaf ABA levels were elevated versus controls.
- Intervention effect Root-applied ABA prevented chilling-induced water stress.
- Intervention effect ABA-fed excised leaves had greater diffusion resistance than non-fed controls at both temperatures.
- Observation More ABA was needed for a given stomatal closure at 3 than 20 degrees C.
