Phototropism Light System (PLS)
Published: 15 September 2015
Plants use light as a signal to orientate their growth in order to maximise light-capture for photosynthesis.
Plants use light as a signal to orientate their growth in order to maximise light-capture for photosynthesis. This re-orientation of growth is called phototropism and is mediated specifically by blue-light. The phototropism LED chamber consists of two blue-light LEDs positioned to illuminate plant seedlings from only one side. A camera attached to the other end of the chamber takes time-lapse images allowing us to track the growth responses of individual seedlings to the unilateral blue-light illumination and calculate kinetics of the phototropic response. The light intensity of the LEDs and the illumination time can be varied from the attached control box, allowing different illumination conditions to be tested.
