Description: Bell-Jar Apparatus during low-pressure test. Radishes were subjected to tests of two hours at pressures of 10 kPa, 25 kPa, 50 kPa and 101 kPa. Infrared temperature sensors and thermocouples inserted into the leaf were used to measure changes in temperature as transpiration increased. Variables such as air temperature and humidity were controlled and recorded during the experiments.
