Other claims from this paper (12)
- Observation In the field, the germination rate of A. amorphoides varied between sites independent of soil relative humidity and landscape.
- Intervention effect A. amorphoides seeds exposed to a water potential of -0.5 MPa showed delayed germination.
- Intervention effect At a water potential of -1.0 MPa germination of A. amorphoides seeds was inhibited by 80%.
- Intervention effect At a water potential of -1.5 MPa germination of A. amorphoides seeds was inhibited by 100%.
- Observation Seeds exposed to the inhibiting water potentials remained viable.
- Observation Oxygen consumption of the seeds did not differ between the water potential treatments.
- Observation Respiration profiles of the treated seeds did not show the same triphasic curve as the control.
- Intervention effect H2O2 and O2- levels in the seeds were not significantly different at the low water potentials of -0.5 and -1.0 MPa.
- Intervention effect Catalase, superoxide dismutase and glutathione reductase activities in the seeds were not significantly different at the low water potentials of -0.5 and -1.0 MPa.
- Intervention effect Only ascorbate peroxidase activity was inhibited at the two low water potentials.
- Observation A. amorphoides seeds remained in phase II during low water potentials without high levels of reactive oxygen species production.
- Mechanism The authors suggest that the seeds continuing to be viable might explain the low influence of humidity and landscape on field germination.
