Abstract
No significant amount of ethylene-C14 was incorporated into the bitter compound, isocoumarin of carrot roots. The results suggest that ethylene action on isocoumarin formation is catalytic. Isocoumarin formation in the presence of ethylene is prevented by short anaerobic treatments. Pretreatment of roots for only 4 days in a N atmosphere with or without ethylene prevented subsequent formation of isocoumarin by the roots when they were placed in air with or without ethylene. High CO2 production occurred during the anaerobic treatment.
