Digital Infrared Thermal Imaging of Crape Myrtle Leaves Infested with Sooty Mold

다국어 초록 (Multilingual Abstract)

The spatial patterns for temperature distribution oncrape myrtle leaves infested with sooty mold wereinvestigated using a digital infrared thermal imagingcamera. The mean temperatures of the control andsooty regions were 26.98oC and 28.44oC, respectively.
In the thermal images, the sooty regions appeared asdistinct spots, indicating that the temperatures in theseareas were higher than those in the control regions onthe same leaves. This suggests that the sooty regionsbecame warmer than their control regions on the adaxialleaf surface. Neither epidermal penetration norcell wall dissolution by the fungus was observed on theadaxial leaf surface. It is likely that the high temperatureof black leaves have an increased cooling load. Toour knowledge, this is the first report on elevated temperaturesin sooty regions, and the results show spatialheterogeneity in temperature distribution across theleaf surface.
