Temperature profiles of the Sauromatum appendix in the presence of 2,6-DHBA. Each set of treatments of in A, C, and E was performed with one pre D-day appendix. The gray line in B, D, F, and H shows the environmental chamber temperature for A, C, E, and G respectively. The temperature along an appendix of an intact inflorescence in shown in (G). Each line color (G) represents a distance from the appendix base and is a subtraction of the environmental chamber temperature from the appendix temperature. Temperature profiles in A, C, and E are a subtraction of the control from a treatment.
