An apparatus is described for the collection of headspace volatiles from comparative samples of watercress in controlled temperature and lighting conditions by adsorption on Porapak Q. Gas chromatographic and mass spectrometric analysis of the volatiles from green watercress with and without a cytokinin treatment, and green and Florida type watercress were compared over a 7‐day period at 10°C in the dark.
