Material of measurement
Advanced infra-red 3D cameras (AIR3DC) installation. Analytical light source is provided by LED1 and LED2 (950 nm) in continuous in dark as well as in light conditions. Normal photosynthetic and/or photomorphogenetic light provided by the fluorescent tubes (not shown) is eliminated in the cameras by a filter which allows only light with a higher wavelength than 850 nm to pass. Therefore the plant can be monitored in light as well as in dark conditions.
Measure of a rhythm in the movement of cotyledons
Upper and side view of cotyledons movements in seedlings of A. thaliana C24. Image samples are shown with the letters corresponding to their time graphics shown below. These latter have been established with a measure each 3 hours
