Other claims from this paper (14)
- Intervention effect Karrikinolide significantly increased germination in all six Byblis species.
- Intervention effect Ethylene significantly increased germination in all six Byblis species.
- Intervention effect Warm dry after-ripening amplified the stimulant response in B. filifolia.
- Intervention effect Warm dry after-ripening amplified the stimulant response in B. rorida.
- Association Seed dormancy depth was partitioned more strongly among habitats than among species.
- Association Germination response to KAR1 was partitioned more strongly among habitats than species.
- Association Germination response to ethylene was partitioned more strongly among habitats than species.
- Association Shallow sandy soil populations produced less dormant seeds than deeper sand or cracking clay populations.
- Observation Shallow soil habitats had higher average upper-soil temperatures.
- Observation Shallow soil habitats had greater diurnal temperature fluctuations.
- Observation Shallow soil habitats had reduced moisture persistence.
- Observation Widely distributed Byblis species show high plasticity in dormancy depth and germination responses among habitats.
- Observation Sympatric species showed similar responses.
- Recommendation The authors recommend further study of plasticity and local adaptation of seed traits.
