4.55～10.4℃。 Both thermal infrared imaging and thermocouples were applied to real time measurement of cut gerbera during vacuum cooling. Surface temperatures of the ligule-shape petal, tubular petal and stem were detected. Results show that there is a significant difference of different parts in average cooling rate, and for the petal and stem, the temperature distribution is nonuniform. The average final temperature obtained with thermal images is 4.55～10.4℃ lower than the thermocouple.
