Abstrakt: A method has been developed for the determination of the radioactivity from C14-labelled ethylene absorbed in aqueous mercuric perchlorate – ethylene glycol. Counting was done on a liquid sample in a gas flow counter. This procedure was designed for the analysis of C14-labelled ethylene evolved by fruit to which possible ethylene precursors had been administered. Total ethylene could be measured manometrically on the same sample. The manometric procedure permitted analysis for ethylene in quantities evolved by one or two tomatoes or other fruit.
