Other claims from this paper (13)
- Observation Phase A water absorption duration did not differ among rice varieties.
- Mechanism The authors suggest phase B duration could explain low-temperature germinability differences.
- Observation The same proportion was reported unchanged in higher-germinability varieties at low temperature, conflicting with the preceding statement.
- Observation Amylase activity rose significantly at germination onset in high-germinability varieties.
- Observation Amylase activity did not increase even at 30 days in low-germinability varieties.
- Observation High-germinability varieties had somewhat high respiration at the end of phase A.
- Observation High-germinability varieties increased respiration significantly at germination onset.
- Observation Low-germinability varieties showed no respiration increase after 30 days.
- Association Oxygen concentration interacted with variety in low-temperature germination.
- Intervention effect Low oxygen delayed germination and rooting in higher-germinability varieties.
- Intervention effect Low oxygen promoted germination and rooting in lower-germinability varieties.
- Observation About 5 per cent oxygen was optimal for inducing or promoting germination in lower-germinability varieties.
- Intervention effect The low-oxygen germination benefit strengthened with longer treatment.
