Other claims from this paper (6)
- Observation Cut stems of Thryptomene vaxicola placed in water showed ultrasonic acoustic emissions after 8 to 12 h.
- Observation No acoustic emissions were found in Thryptomene calycina stems within 100 h.
- Observation Air-dehydrated cut stems of T. saxicola showed a primary peak in acoustic emission frequency after 3 to 5 h.
- Observation Water uptake rates of T. calycina after dehydration were not lower than in controls not held dry.
- Intervention effect Water uptake rates of T. saxicola decreased after 16 h of dehydration and were very low after 24 h.
- Intervention effect Recutting the stems under water prevented acoustic emissions in T. saxicola stems placed in water.
