Other claims from this paper (19)
- Intervention effect Low temperature vernalization was reversed at 18°C or higher, increasingly at higher temperature.
- Intervention effect Short day vernalization was greatest at 18°C and decreased above 22°C.
- Intervention effect Short days hastened heading even at 30°C.
- Intervention effect High temperature after short days retarded heading less than during short days.
- Observation Short day vernalization became stable to high temperature earlier than low temperature vernalization.
- Intervention effect Without seed chilling, heading hastening by short days at 26°C or 30°C was smaller than outdoors.
- Intervention effect Chilled plants showed the same heading hastening under both temperature conditions.
- Association Winter habit was unrelated to high temperature reduction of short day vernalization.
- Observation Kobinkatagi No. 36 differed from four other varieties in the reduction.
- Intervention effect High night temperature affected heading hastening more than high daytime temperature.
- Association Heading hastening reduction was closely related to duration of high temperature within 24 hours.
- Mechanism High temperature decline in short day vernalization was attributed more to partial destruction of its effect than slowed short day reaction.
- Observation Short day devernalization was pronounced around 26°C or higher.
- Intervention effect Intercalated long days reduced short day vernalization.
- Intervention effect Separately intercalated long days caused stronger devernalization than a series.
- Intervention effect Alternating single short and long days completely reversed short day vernalization.
- Intervention effect Long days in the former half of short days caused stronger devernalization.
- Intervention effect High temperature during intercalated long days caused stronger devernalization.
- Mechanism Short day vernalization may play an important role in heading of autumn-sown barley.
