Abstract
Daily CO2 exchanges have been followed on Sinapis alba L., grown in short or long day conditions. For the CO2 measurements three types of experimental conditions have been used, differing in the level and duration of daylight.
The shape of the night respiration curve is affected by the previous photoperiodic regime, while the shape of daily apparent photosynthesis is not. There is a beneficial effect of lengthening the light period for the same daily energy amount on CO2 balance, specially on the short day grown plant.
In all daylengths, for long and short day grown plants, there is a significant correlation between CO2 gain in the light and loss in the dark. The results suggest that this dependence may be different in short and long day plants.
