Experimental setup for AIRT; temperature curves of aluminium and a Ficus benjamini leave

(A) Experimental setup.

(B) Infrared heaters before, after and during the heat pulse.

(C) This figure shows the background temperature (aluminium) and the temperature of a leaf sample (Ficus benjamini) during and after heat pulse application (pulse duration: 1.15 s). Background temperature was measured by placing crumpled aluminium foil in the center of the heater beam.
