Abstract
Ethylene stimulated the activity of l‐phenylalanine ammonia‐lyase (PAL) in carrot (Daucus carota L.) tissues. It is also known to induce the formation of isochlorogenic acid. However, the induction patterns were different for isochlorogenic acid and PAL activity. Ethylene action seems to be indirect, as it did not affect the PAL activity of cell‐free extracts.Keywords
