LEAF TEMPERATURE PEAKS AFTER WITHDRAWAL OF THERMAL SCREENS |
| Authors: | Otto F. Nielsen, Marius G. Amsen |
| Abstract:
Leaf temperatures were recorded at intervals of 20 s with an infrared thermometer. An temporary increase in leaf temperature of 3°C was typically recorded within the first few minutes after the withdrawal of the thermal screens. This peak is observed in a single glass greenhouse with thermal screens, shading curtains and capillary benches. The peak is not found in the same type of house with slatted benches, nor in a twin walled PMMA greenhouse without thermal screens, but with shading curtains and capillary benches. | |
