Abstract:
A small lightweight leaf movement recording system using a strain gauge coupled to an amplifier and a recorder was devised. The need for such a system was dictated by the physical limitations of an orbiting capsule. We have also found that such a system is useful for earthbound experiments was devised. The small size of the sensing unit makes it possible to place several units on a single plant. The monitored plant can easily be placed in a small control chamber and continuous records of several weeks duration can be obtained when the movements are recorded on a strip chart recorder.
