Temperatures experienced by an ear of wheat in the sample chamber. The air conditioning temperature was set either at room temperature, or 3 °C higher, or 6 °C higher. The difference between mean sample temperature and the temperature of the incoming air are plotted depending on PPFD level. The error bars represent the standard error associated with thermocouple measurements made at various positions on an ear triplicate
