Other claims from this paper (7)
- Observation Where changes in photosynthesis occurred, they took place at the same time but usually lacked a clear-cut diurnal pattern.
- Observation Under both temperatures, one type of diurnal photosynthetic change showed no change and the other showed some decrease during night hours.
- Observation Italian ryegrass, red clover and orchard grass remained unchanged in photosynthesis throughout day and night and were non-sensitive to temperature.
- Observation Rye remained unchanged in photosynthesis throughout day and night and was non-sensitive to temperature.
- Intervention effect Dallisgrass, Sudangrass and new sorgo showed depression in photosynthesis when the temperature level fell beyond their optimum range, with little change within it.
- Observation Teosinte and common vetch showed depression in photosynthesis during night hours under both temperature levels.
- Observation Respiration of the forage crops showed a gradual decrease as time passed under both temperature levels.
