Abstract
Symptom of high temperature injury of pale green and dark green leaves of Oncidium under the same sunlight condition was investigated. Although the flavonoid content in pale green leaves was larger than dark green leaves, carotenoid content, superoxide dismutase, ascorbate peroxidase, catalase activities and hydrogen peroxide content were smaller. However, by exposure to high temperatures (42°C maximum air temperature) for 4 days, 31% area of pale green leaves was sunburned, whereas dark green leaves were completely burned. Thus, the high temperature injury in pale green leaves was comparatively mitigated compared with that of dark green leaves in Oncidium plants.
