Other claims from this paper (11)
- Observation Audio acoustic emissions were attenuated less and travelled further than ultrasonic emissions in plant materials generally.
- Observation Audio acoustic emissions travelled considerably more than 40 mm in all species tested.
- Observation Ultrasonic emissions in Thuja were transmitted up to 40 mm.
- Observation Ultrasonic emissions in a range of other species were transmitted only up to 10 mm.
- Observation Thuja produced fewer audio acoustic emissions than ultrasonic emissions.
- Observation Tasmannia produced fewer audio acoustic emissions than ultrasonic emissions.
- Observation In Ricinus, audio acoustic emissions tended to predominate over ultrasonic emissions.
- Observation Ultrasonic emissions were produced in abundance when excised stem tissue was dehydrated.
- Observation The dual-probe technique is useful for locating sites of cavitation in whole plants.
- Observation Audio acoustic emission detection ranged from 0.13% to 5.1% of counting units.
- Observation Ultrasonic emission detection was considerably greater, ranging from 27% to 76%.
