Suppl Fig. 3. Experimental setting for measuring
ethylene production in Petri plates. A-B The
lower part of a Petri dish with the agar was
covered with a glass plate with an inlet and
outlet for gas flow and assembled leak-tided
between two metal pieces. C Experimental setting
allowing the alternated measurement of four
plates with seedlings and one empty plate (to
correct background noise) connected the ETD300
photoacoustic ethylene detector (Sensor-Sense,
Nijmegen, the Netherlands).
