Abstract

The temperatures on the surfaces of intact Scindapsus (pothos lime) leaves subjected to ultraviolet radiation (UV-A, UV-B) as a function of time were investigated. The thermal images of leaves were taken at intervals of 1 min for 2 to approximately 11 h using a thermal video system, by which thermal information in the 3 to 5.4 micrometer infrared band were recorded. After the tests, the difference between the mean temperature of the leaf and the atmospheric temperature at each time point under each condition was determined. The results showed that the temperature differences for UV-A and UV-B irradiation were different from those for visible light supplied by a green house lamp. Therefore, the temperature on the leaf surface suggested the possibility of applications in the prediction of the level of UV-A and UV-B radiation.
