Summary Investigations about global radiation losses in cuvettes, in dependence upon their exposure, showed losses of 20% of the daily radiation sum due to absorption by the cuvette material. Changing the cuvette angle from the horizontal led to considerably higher losses as a result of the radiation coming through the sides and corners of the chamber. If the chamber is kept horizontal and oriented in a north-south exposure the daily radiation losses remain relatively constant. The effect of the radiation losses due to the cuvettes must primarily be considered when the light saturation of the experimental plants in the chamber is not surpassed. |
