- Observation At 15°C the three wild oat types differed little in seed dormancy.
- Observation At 20°C type fA had a larger dormant seed proportion than fB or fC.
- Observation Overall dormancy was 97% for seed produced at 15°C.
- Observation Overall dormancy was 63% for seed produced at 20°C.
- Intervention effect Water stress reduced viable seed production.
- Intervention effect High temperature reduced viable seed production.
- Observation Without water stress, seed matured at 15°C had 10% first-autumn emergence.
- Observation Without water stress, seed matured at 20°C had 30% first-autumn emergence.
- Observation With water stress at 15°C, emergence was 47%.
- Observation With water stress at 20°C, emergence was 78%.
- Observation Petri dish tests indicated seed from hot dry summers was less dormant than seed from cool moist summers.
