Other claims from this paper (10)
- Intervention effect Germination rose from 87.2% to 99.2% as alternating temperature rose from 5:15°C to 10:20°C.
- Intervention effect Germination declined as alternating temperature rose beyond 10:20°C.
- Intervention effect Seeds did not germinate at 25:35°C under the stated photoperiod.
- Intervention effect Darkness yielded similar final germination to light.
- Intervention effect Constant and alternating temperature gave similar germination patterns.
- Intervention effect Final germination percentage did not differ significantly between alternating and constant temperatures.
- Intervention effect Germination rate did not differ significantly between alternating and constant temperatures.
- Intervention effect Germination exceeded 74.4% without significant differences across light intensities.
- Intervention effect Germination rate followed the same pattern as final germination across water potentials.
- Recommendation The authors recommend seed dispersal from early to mid-May for better germination.
