- Intervention effect A 28 °C day temperature generally delayed awn emergence except under longer days for Athenais or Arabi Abiad.
- Observation At lower temperatures and short photoperiods, time to awn emergence in five barley genotypes followed a genotype-specific temperature and photoperiod equation.
- Observation Arabi Abiad showed no significant temperature response.
- Intervention effect Seed low-temperature pretreatment reduced time to awn emergence in Athenais.
- Intervention effect Seed low-temperature pretreatment reduced time to awn emergence in Ager, Arabi Abiad and Gerbel B, especially in longer days.
- Observation Seed low-temperature pretreatment had no effect or tended to delay awn emergence in Emir and Mona.
- Observation The critical photoperiod in spring-sown barley types exceeded 16 h d−1.
- Observation The critical photoperiod was approximately 13 h d−1 in Ager.
- Observation The critical photoperiod was just over 13 h d−1 in Gerbel B.
- Observation Vernalized Arabi Abiad had a critical photoperiod almost 15 h.
- Observation In Athenais, critical photoperiod rose from about 12·5 h d−1 at 10 °C to about 15 h d−1 at 20 °C irrespective of seed vernalization.
