From: Water balance altered in cucumber plants infected with Fusarium oxysporum f. sp. cucumerinum

Response of the leaf temperature to the light intensity in the healthy and FOC-infected cucumber plants.
The light intensity changed from 10,000 Lux to 0 Lux. The leaf temperature was recorded by digital infrared thermography. ΔT represents the temperature difference between the leaf temperature and the environmental temperature.
