Other claims from this paper (9)
- Intervention effect Cold pretreatment made net oxygen consumption decline faster than warm pretreatment.
- Intervention effect Red preirradiation enhanced the cold effect on oxygen consumption.
- Intervention effect Cold pretreatment brought the oxygen compensation point sooner than warm pretreatment.
- Intervention effect A following warm dark pretreatment nullified the cold effect on oxygen compensation.
- Observation Cold and red-light treated leaves had a strong early carbon dioxide release burst.
- Association Oxygen uptake and the high carbon dioxide release showed no apparent correlation.
- Intervention effect Cold dark pretreatment decreased later carbon dioxide release.
- Intervention effect The authors infer red preirradiation and cold pretreatment stimulate photosynthetic oxygen evolution and carbon dioxide uptake.
- Mechanism The authors hypothesize pretreatment causes carbon dioxide release unrelated directly to respiration or photorespiration.
